Failed monetary technology

Archaic and ignored monetary technologies can be very interesting, especially when they teach us about newer attempts to update our monetary system. I recently stumbled on a neat monetary innovation from the bimetallic debate of the late 1800s, Nicholas Veeder's Republic of Eutopia coin:
If you've read this blog for a while, you'll know that I like to talk about monetary technology. Unlike financial technology, monetary tech involves a technological or sociological upgrade to the monetary system itself. And since we are all unavoidably users of the monetary system—we all think and calculate in terms of our nations unit of account—each of us is immediately affected by the change.

Veeder's Eutopia coin is an old monetary technology that was never adopted. More recent examples of unadopted (or as-yet not adopted) montech include Fedcoin, NGDP futures targeting, or Miles Kimball's technique for evading the zero-lower bound, which would decouple the value of paper money from electronic money. Examples of recent monetary tech that went on to be adopted include the switch from paper to plastic banknotes, the replacement of older end-of-day clearing systems to real time gross settlement systems, and inflation targeting.

Fintech is more limited in scope than monetary tech. Only that portion of the population that uses these innovations is affected—everyone else's financial habits continues on as before. Recent examples include bitcoin, p2p lending, and roboadvisors. (If bitcoin ever became the standard unit of account, it would have made the trek over to becoming monetary technology, and not just fintech.)

-------------

To make sense of Veeder's Republic of Eutopia coin, we need to understand the problem that his monetary innovation was meant to solve. Most nations were on a gold standard by the 1870s, and with the price of gold rising, the world price level was generally falling. This development provided an unexpected boost to the creditor class, who were owed gold, while hurting the debtor class, who owed gold. A higher price for the yellow metal meant that the loan contract to which a debtor had signed their name now required them to work that much harder to pay it off.

In that context, a broad popular movement for the remonetization of silver emerged. Prior to being on gold standards, nations were generally on a pure silver standard or a bimetallic standard. On a gold standard the debtor class had only one way to settle the debt, by providing the proper amount of gold coins. But if silver coinage was reintroduced at the old rate of sixteen-to-one, debtors could instead sell their labour to buy cheap silver, have it minted into legal tender silver coins, and use those silver coins to pay off the debt. Paying their debts with silver rather than gold meant they'd have a bigger amount of wealth remaining in their pocket.

The movement to restore bimetallism wasn't purely a populist one. The smartest economists of the time--folks like Irving Fisher, Leon Walras, and Alfred Marshall--also preferred bimetallism. A bimetallic standard recruits more monetary material into service than a gold standard. This is advantageous because, as Fisher put it, it "spreads the effect of any single fluctuation over the combined gold and silver markets." In other words, the evolution of the price level under a bimetallic system should be more stable—and thus more fair—than under a monometallic system, since it can absorb larger shocks.

The problem with bimetallism is that it very quickly runs smack into Gresham's law. The traditional way to bring the two metals into service as monetary material was to offer to mint both high denomination gold coins and lower denomination silver coins. So if a merchant needed £20 worth of coins, he could bring either a chunk of raw gold to the mint, or an even bigger chunk of pure silver, and the mint would convert either chunk into £20 for him. The specified amounts of raw silver or raw gold that were required to get a certain number of £-denominated coins constituted the mint's official gold-to-silver exchange rate.

Inevitably the market's gold-to-silver exchange rate would diverge from the mint's official exchange rate, effectively over- or undervaluing one of the two metals. In this situation, no one would bring any of the overvalued metal to the mint to be turned into coins. After all, why bother minting a chunk of gold (assuming the yellow metal was the overvalued one) into £20 worth of coins if that same amount of gold has far more purchasing power overseas? The overvalued metal would thus disappear as it was hoarded and exported, leaving only the undervalued metal in circulation. A monometallic standard had accidentally emerged, and all the benefits of bimetallism were for not.

To prevent Gresham's law from being engaged, the mint had to constantly adjust its official rate so that it stayed in-line with the ever-evolving market rate. Not only would these changes have been politically costly, but they would required an expensive series of recoinages in order to ensure that coins always had the proper amount of silver or gold in them.

--------

Enter Veeder's Eutopia coin. Nicholas Veeder was no economist, but an executive at C.G. Hussey, a copper rolling mill in Pittsburgh. In 1885, he published a pamphlet with the wordy title Cometallism: A Plan for Combining Gold and Silver in Coinage, for Uniting and Blending their Values in Paper Money and For Establishing a Composite Single Standard Dollar of Account.

Rather than defining a dollar as simultaneously a fixed amount of gold OR a fixed amount of silver, Veeder's pamphlet suggested defining it as a fusion of the two together. Specifically, Veeder's dollar was to contain 12.9 grains of gold AND 206.25 grains of silver. It's worth noting that under a proposed cometallic standard, paper dollars needn't be redeemed with actual Eutopia coins, but could be converted into separate silver and gold bars or coins. The important rule was that each dollar's worth of debt had to be discharged with 12.9 grains of gold and 206.25 grain of silver.

A model of a cometallic gold certificate, from page 60 of Veeder's pamphlet on cometallism

Veeder's cometallic scheme was a neat way to keep all the benefits of bimetallism with none of its drawbacks. Cometallism would draw on the combined supplies of the gold and silver markets, so that the system would be much more elastic than a pure gold standard, and thus fairer to both creditors and debtors. At the same time, Gresham's law would be avoided. Under traditional bimetallic coin systems, the mint established an exchange rate between the two metals. This rate inevitably became the system's undoing when it diverged from the true rate.

But a mint that was operating under a cometallic standard would only accept fixed quantities of silver AND gold before it would mint a $1 coin, and so it would no longer be setting an exchange rate between the two precious metals. The undervaluation of one of the metals, a key ingredient for Gresham's law, could never emerge under cometallism.

---------

A year after Veeder published his pamphlet, Alfred Marshall—one of the world's leading economists—described a remarkably similar system. Here is part of his response to the Royal Commission on the Depression in Trade and Industry in 1886, which had been convened to address the Long Depression:
"I propose that currency should be exchangeable at the Mint or Issue Department not for gold, but for gold and silver, at the rate of not £1 for 113 grains of gold, but £1 for 56^ grains of gold, together with, say, twenty times as many grains of silver. I would make up the gold and silver bars in gramme weights, so as to be useful for international trade. A gold bar of 100 grammes, together with a silver bar, say, twenty * times as heavy, would be exchangeable at the Issue Department for an amount of the currency which would be calcalated and fixed once for all when the scheme was introduced. (It would be about .€28 or .€30 according to the basis of calculation)."
Marshall's proposal was later dubbed symmetallism. (I wrote about it here.) If you study monetary systems, you'll run into the gold & silver basket idea sooner or later. The concept is invariably refereed to as symmetallism (and not cometallism) and attributed to Marshall (not Veeder). In the 1800s academics were not required to provide references, and from what I understand plagiarism was rampant. Did Marshall develop his idea separately from Veeder, or did he rip it off? Whatever the case, Veeder was an unknown executive at a small manufacturing concern, whereas Marshall a world famous academic. Celebrity carried the day.

---------

Interestingly, Veeder himself probably borrowed the idea, or at least part of it, from someone else. Almost a decade earlier, William Wheeler Hubbell had tried to get the U.S. congress to adopt the so-called "goloid dollar," a coin containing silver and gold alloyed together.
Hubbell owned the patent to the goloid alloy, so he would have made a good profit if the goloid dollar had been adopted by the U.S. Treasury. Unlike Veeder, Hubbell doesn't seem to have been a very good monetary economist, and the case he makes for goloid misses much of nuances of the benefits of bimetallism and the hazards of Gresham's law. He lists a number of advantages for his proposed coin, including: superior durability to gold and silver coins; not susceptible to oxidization (unlike silver); a goloid dollar was smaller than a silver dollar and thus more convenient for consumers to carry around; the mint would be able to make more goloid dollars than silver dollars with its existing capacity; and goloid coins could not be easily melted down for usage in the arts as was the case with gold and silver coins.

Hubbell's idea foundered on the fact that a goloid coin, despite containing gold, has almost the exact same colour as a silver coin. Hubbell's critics believed this set the coin up to be widely counterfeited. A counterfeiter could make a replica with lower gold content, this alteration unlikely to be noticed by the public since the colour of a genuine goloid coin and the fake would be the same.

The difficulties that Hubbell experienced alloying gold and silver were not lost on Veeder. In has pamphlet he mentions that "my first approach, as with many other persons, was to combine the two metals as an alloy for coinage, but, owing to certain difficulties... this idea was soon considered impracticable and abandoned." To avoid Hubbell's color problem, Veeder ended up mechanically wedding the two metals rather than chemically combining them, the Eutopia coin being comprised of a ring of silver and a gold plug embedded inside.

--------------

The topic of goloid and Eutopia dollars seem a bit obscure, but the issues of stability and fairness that concerned monetary technologists in the late 1800s remain relevant today.

Today, most western central banks define the national currency in terms of a basket of consumer goods and services rather than a fixed amount of gold (gold monometallism) or a basket of gold & silver (cometallism, symmetallism). This makes a lot of sense. If we want to create a stable monetary standard, one that provides creditors and debtors with an even playing field, better to use a broad basket of stuff that regular people buy than a narrow basket of metals. That way all parties to a contract know many years ahead of time exactly how much consumer goods they will get (if they are creditors) or give up (if they are debtors). Knowing how much gold and silver baskets they will owe or be owed is less relevant to the average person, since gold and silver are a very small part of most people's day-to-day consumption profiles.

There is an important debate going on today about whether to continue defining national currencies in terms of a consumer goods & services basket, or whether to move to something more fluid like a nominal gross domestic product (NGDP), or output. One problem with using a consumer goods basket is that, in the event of a large economic shock that leads to significant loss of jobs, debtors take on all the macroeconomic risk. After all, they owe just as many CPI baskets as before, but have less capacity to meet that obligation because they might not have a job. This doesn't seem like a fair splitting up of risks and rewards.

The nice thing about defining the national currency in terms of NGDP, or output, is that the risk of a large shock, and the associated loss of jobs, is shared between creditors and debtors. This is because if a recession occurs, debtors will owe a smaller amount of real wealth to creditors than they otherwise would. And during a boom, when the job offers are rolling in, creditors will owe more.

Cometallism was never adopted. Perhaps it was a bit too fancy. NGDP is a bit exotic too, but then again so were many forms of monetary technology, until they were actually adopted and became part of the background. We'll have to see what happens.

From ancient electrum to modern currency baskets (with a quick detour through symmetallism)

Electrum coins [source]

First proposed by economist Alfred Marshall in the late 19th century as an alternative metallic standard to the gold, silver and bimetallic standards, symmetallism was widely debated at the time but never adopted. Marshall's idea amounted to fusing together fixed quantities of silver and gold in the same coin rather than striking separate gold and/or silver coins. Symmetallism is actually one of the world's oldest monetary standards. In the seventh century B.C., the kingdom of Lydia struck the first coins out of electrum, a naturally occurring mix of gold and silver. Electrum coins are captured in the above photo.

While symmetallism is an archaic concept, it has at least some relevance to today's world. Modern currencies that are pegged to the dollar (like the Hong Kong dollar) act very much like currencies on a gold standard, the dollar filling in for the role of gold. A shift from a dollar peg to one involving a basket of other currencies amounts to the adoption of a modern version of Marshall's symmetallic standard, the euro/yen/etc playing the role of electrum.

The most recent of these shifts has occurred with China, which late last year said it would be measuring the renminbi against a trade-weighted basket of 13 currencies rather than just the U.S. dollar. Thus many of the same issues that were at stake back at the turn of the 19th century when Marshall dreamt up the idea of symmetallism are relevant today.

So what exactly is symmetallism? In the late 1800s, the dominant monetary debate concerned the relative merits of the gold standard and its alternatives, the best known of which was a bimetallic standard. The western world, which was mostly on a gold standard back then, had experienced a steady deflation in prices since 1875. This "cross of gold" was damaging to debtors; they had to settle with a higher real quantity of currency. The reintroduction of silver as legal tender would mean that debts could be paid off with a lower real amount of resources. No wonder the debtor class was a strong proponent of bimetallism.

There was more to the debate than mere class interests. As long as prices and wages were rigid, insufficient supplies of gold in the face of strong gold demand might aggravate business cycle downturns. For this reason, leading economists of the day like Alfred Marshall, Leon Walras, and Irving Fisher mostly agreed that a bimetallic standard was superior to either a silver standard or a gold standard. (And a hundred or so years later, Milton Friedman would come to the same conclusion.)

The advantage of a bimetallic standard is that the price level is held hostage to not just one precious metal but two; silver and gold. This means that bimetallism is likely to be less fickle than a monometallic standard. As Irving Fisher said: "Bimetallism spreads the effect of any single fluctuation over the combined gold and silver markets."  Thus if the late 1800s standard had been moved from a gold basis to a bimetallic one, the stock of monetary material would have grown to include silver, thus 'venting' deflationary pressures.

Despite these benefits, everyone admitted that classical bimetallism had a major weakness; eventually it ran into Gresham's law. Under bimetallism, the mint advertised how many coins that it would fabricate out of pound of silver or gold, in effect setting a rate between the two metals. If the mint's rate differed too much from the market rate, no one would bring the undervalued metal (say silver) to the mint, preferring to hoard it or export it overseas where it was properly valued. The result would be small denomination silver coin shortages, which complicated trade. What had started out as a bimetallic standard thus degenerated into an unofficial gold standard (or a silver one) so that once again the nation's price level was held hostage to just one metal.

The genius of Alfred Marshall's symmetallic standard was that it salvaged the benefits of a bimetallic standard from Gresham's law. Instead of defining the pound as either a fixed quantity of gold or silver, the pound was to be defined as a fixed quantity of gold twinned with a fixed quantity of silver, or as electrum. Thus a £1 note or token coin would be exchangeable at the Bank of England not for, say, 113 grains of gold, but for 56 grains of gold together with twenty or so times as many grains of silver. The number of silver and gold grains in each pound would be fixed indefinitely when the standard was introduced.

Because symmetallism fuses gold and silver into super-commodity, the monetary authority no longer sets the price ratio between the two metals. Gresham's law, which afflicts any bimetallic system when one of the two metals is artificially undervalued, was no longer free to operate. At the same time, the quantity of metal recruited into monetary purposes was much larger and more diverse than under a monometallic standard, thus reducing the effect of fluctuations in the precious metals market on aggregate demand.

While symmetallism was an elegant solution, Alfred Marshall was lukewarm to his own idea, noting that "it is with great diffidence that I suggest an alternative bimetallic scheme." To achieve a stable price level, Marshall preferred a complete separation of the unit of account, the pound, from the media of exchange, notes and coins. This was called a tabular standard, a system earlier proposed by William Stanley Jevons. The idea went nowhere, however; the only nation I know that has implemented such a standard is Chile. As for Fisher, he proposed his own compensated dollar standard plan, which I described here.

The urgency to adopt a new standard diminished as gold discoveries in South Africa and the Yukon spurred production higher, thus reducing deflationary pressures. None of these exotic plans—Marshall's symmetallism, Jevons tabular standard, or Fisher's compensated dollar—would ever be adopted. Rather, the world kept on limping forward under various forms of the gold standard. This standard would be progressively modified through the years in order to conserve on the necessity for gold, first by removing gold coin from circulation and substituting convertibility into gold bars (a gold bullion standard) and then having one (or two) nations take on the task of maintaining gold convertibility while the remaining nations pegged to that nation's currency (a gold exchange standard).

---

Let's bring this back to the present. In the same way that conditions in the gold market caused deflation among gold standard countries in the late 1800s, the huge rise in the U.S. dollar over the last few years has tightened monetary conditions in all those nations that peg their currency to the dollar. To cope, many of these countries have devalued their currencies, a development that Lars Christensen has called an 'unraveling of the dollar bloc.'

A more lasting alternative to re-rating a U.S. dollar peg might be to create a fiat version of electrum; mix the U.S. dollar with other currencies like the euro and yen to create a currency basket and peg to this basket. China, which has been the most important member of the dollar bloc, has turned to the modern version of symmetallism by placing less emphasis on pegging to the U.S. dollar and more emphasis on measuring the yuan against a trade-weighted basket of currencies. This means that where before China had a strictly made-in-the U.S. monetary policy, its price level is now determined by more diverse forces. Better to put your eggs in two or three baskets than just one.

Bahrain, Oman, Qatar, Saudi Arabia and United Arab Emirates are also members of the dollar bloc. Kuwait, however, links its dinar to a basket of currencies, a policy it adopted in 2007 to cope with the inflationary fallout from the weakening U.S. dollar. In an FT article from April entitled Kuwaiti currency basket yield benefits, the point is made that Kuwait has enjoyed a more flexible monetary policy than its neighbours over the recent period of U.S. dollar strength. Look for the other GCC countries to mull over Kuwaiti-style electrum if the U.S. dollar, currently in holding pattern, starts to rise again.

Modern day electrum can get downright exotic. Jeffrey Frankel, for instance, has suggested including commodities among the basket of fiat currencies, specifically oil in the case of the GCC nations. Such a basket would allow oil producing countries to better weather commodity shocks than if they remained on their dollar pegs. If you want to pursue these ideas further, wander over to Lars Christensen's blog where Frankel's peg the export price plan is a regular subject of conversation.

A 21st century gold standard



Imagine waking up in the morning and checking the hockey scores, news, the weather, and how much the central bank has adjusted the gold content of the dollar overnight. This is what a 21st century gold standard would look like.

Central banks that have operated old fashioned gold standards don't modify the gold price. Rather, they maintain a gold window through which they redeem a constant amount of central bank notes and deposits with gold, say $1200 per ounce of gold, or equivalently $1 with 0.36 grains. And that price stays fixed forever.

Because gold is a volatile commodity, linking a nation's unit of account to it can be hazardous. When a mine unexpectedly shuts down in some remote part of the world, the necessary price adjustments to accommodate the sudden shortage must be born by all those economies that use a gold-based unit of account in the form of deflation. Alternatively, if a new technology for mining gold is discovered, the reduction in the real price of gold is felt by gold-based economies via inflation.

Here's a modern fix that still includes gold. Rather than redeeming dollar bills and deposits with a permanently fixed quantity of gold, a central bank redeems dollars with whatever amount of gold approximates a fixed basket of consumer goods. This means that your dollar might be exchangeable for 0.34 grains one day at the gold window, or 0.41 the next. Regardless, it will always purchase the same consumer basket.

Under a variable gold dollar scheme the shuttering of a large gold mine won't have any effect on the general price level. As the price of gold begins to skyrocket, consumer prices--the reciprocal of a gold-linked dollar--will start to plummet. The central bank offsets this shock by simply redefining the dollar to contain less gold grains than before. With each grain in the dollar more valuable but the dollar containing fewer grains of the yellow metal, the dollar's intrinsic value remains constant. This shelters the general price level from deflation.

This was Irving Fisher's 1911 compensated dollar plan  (see chapter 13 of the Purchasing Power of Money), the idea being to 'compensate' for changes in gold's purchasing power by modifying the gold content of the dollar. A 1% increase in consumer prices was to be counterbalanced by a ~1% increase in the number of gold grains the dollar, and vice versa. Fisher referred to this fluctuating definition as the 'virtual dollar':

From A Compensated Dollar, 1913

Fisher acknowledged that 'embarrassing' speculation was one of the faults of the system. Say the government's consumer price report is to be published tomorrow and everyone knows ahead of time that the number will show that prices are rising too slow. And therefore, the public expects that the central bank will have to increase its gold buying price tomorrow, or, put differently, devalue the virtual dollar so it is worth fewer ounces of gold. As such, everyone will rush to exchange dollars for gold at the gold window ahead of the announcement and sell back the gold tomorrow at the higher price. The central bank becomes a patsy.

Fisher's suggested fix  was to introduce transaction costs, namely by setting a wide difference between the price at which the central bank bought and sold gold. This would make it too expensive buy gold one day and sell it the next. This wasn't a perfect fix because if the price of gold had to be adjusted by a large margin the next day in order to keep prices even, say because a financial crisis had hit, then even with transaction costs it would still be profitable to game the system.

A more modern fix would be to adjust the gold content of the virtual dollar in real-time in order to remove the window of opportunity for profitable speculation. Given that consumer prices are not reported in real-time, how can the central bank arrive at the proper real-time gold price? David Glasner once suggested targeting the expectation. Rather than aiming at an inflation target, the central bank targets a real-time market-based indicator of inflation expectations, say the TIPS spread. So if inflation expectations rise above a target of 2% for a few moments, a central bank algorithm rapidly reduces its gold buying price until expectations fall back to target. Conversely, if expectations suddenly dip below target, over the next few seconds the algorithm will quickly ratchet down the content of gold in the dollar to whatever quantity is sufficient to restore the target (i.e. it increases the price of gold).

Gold purists will complain that this is a gold standard in name only. And they wouldn't be entirely wrong. Instead of defining the dollar in terms of gold, a compensated dollar scheme could just as well define it as a varying quantity of S&P 500 ETF units, euros, 10-year Treasury bonds, or any other asset. No matter what instrument is being used, the principles of the system would be the same.

A compensated dollar scheme isn't just a historical curiosity; it may have some relevance in our current low-interest rate environment. Lars Christensen and Nick Rowe have pointed out that one advantage of Fisher's plan is that it isn't plagued by the zero lower bound problem. Our current system depends on an interest rate as its main tool for controlling prices. But once the interest rate that a central bank pays on deposits has fallen below 0%, the public begins to convert all negative-yielding deposits into 0% yielding cash. At this point, any further attempt to fight a deflation with rate cuts is not possible. The central banker's ability to regulate the purchasing power of money has broken down.*

Under a Fisher scheme the tool that is used to control purchasing power is the price of gold, or the gold content of the virtual dollar, not an interest rate. And since the price of gold can rise or fall forever (or alternatively, a dollars gold content can always grow or fall), the scheme never loses its potency.

Ok, that is not entirely correct. In the same way that our modern system can be crippled under a certain set of circumstances (negative rates and a run into cash), a Fisherian compensated dollar plan had its own Achilles heel. If gold coins circulate along with paper money and deposits, then every time the central bank reduces the gold content of the virtual dollar in order to offset deflation it will have to simultaneously call in and remint every coin in circulation in order to keep the gold content of the coinage in line with notes and deposits. This series of recoinages would be a hugely inconvenient and expensive.

If the central bank puts off the necessary recoinage, a compensated dollar scheme can get downright dangerous. Say that consumer prices are falling too fast (i.e. the dollar is getting too valuable) such that the central banker has to compensate by reducing the gold content of the virtual dollar from 0.36 grains to 0.18 grains (I only choose such a large drop because it is convenient to do the math). Put differently, it needs to double the gold price to $2800/oz from $1400. Since the central bank chooses to avoid a recoinage, circulating gold coins still contain 0.36 grains.

The public will start to engage in an arbitrage trade at the expense of the central bank that goes like this: melt down a coin with 0.36 grains and bring the gold bullion to the central bank to have it minted into two coins, each with 0.36 grains (remember, the central bank promises to turn 0.18 grains into a dollar, whether that be a dollar bill, a dollar deposit, or a dollar coin, and vice versa). Next, melt down those two coins and take the resulting 0.72 grains to the mint to be turned into four coins. An individual now owns 1.44 grains, each coin with 0.36 grains. Wash and repeat. To combat this gaming of the system the government will declare the melting-down of  coin illegal, but preventing people from running garage-based smelters would be pretty much impossible. The inevitable conclusion is that the public increases their stash of gold exponentially until the central bank goes bankrupt.

This means that a central bank on a compensated dollar that issues gold coins along with notes/deposits will never be able to fight off a deflation. After all, if it follows its rule and reduces the gold content of the virtual dollar below the coin lower bound, or the number of grains of gold in coin, the central bank implodes. This is the same sort of deflationary impotence that a modern rate-setting central bank faces in the context of the zero lower bound to interest rates.

In our modern system, one way to get rid of the zero lower bound is to ban cash, or at least stop printing it. Likewise, in Fisher's system, getting rid of gold coins (or at least closing the mint and letting existing coin stay in circulation) would remove the coin lower bound and restore the potency of a central bank. Fisher himself was amenable to the idea of removing coins altogether. In today's world, the drawbacks of a compensated dollar plan are less salient as gold coins have by-and-large given way to notes and small base metal tokens.

In addition to evading the lower bound problem, a compensated dollar plan would also be better than a string of perpetually useless quantitative easing programs. The problem with quantitative easing is that commitments to purchase, while substantial in size, are not made at any particular price, and therefore private investors can easily trade against the purchases and nullify their effect. The result is that the market price of assets purchased will be pretty much the same whether QE is implemented or not. Engaging in QE is sort of like trying to change the direction of the wind by waving a flag, or, as Miles Kimball once said, moving the economy with a giant fan. A compensated dollar plan directly modifies the price of gold, or, alternatively, the gold content of the dollar, and therefore has an immediate and unambiguous effect on purchasing power. If central bankers adopted Fisher's plan, no one would ever accuse them of powerlessness again.



*Technically, interest rates need never lose their potency if Miles Kimball's crawling peg plan is adopted. See here.

Alberta Prosperity Certificates and a Greek parallel currency



This post is about the Alberta Prosperity Certificate, one of the world's stranger monetary experiments. Issued in late 1936 and early 1937 by the newly-elected Alberta government, these monetary instruments are the largest-scale example of Silvio Gesell's "shrinking money," or stamp scrip, in action. Gesell, a German business man and self taught economist, had written a treatise in 1891 in which he described a currency that depreciated in value, thus preventing hoarding and encouraging spending.

To make this more interesting, let's jump forward in time. In 2014, Greece's Finance Minister Yanis Varoufakis wrote a blog post that described a new Greek financial instrument that could be used to make payments while circulating in parallel with the already-existing euro. Varoufakis's post, combined with constant rumors that Greece may be planning to issue its own parallel currency in order to make internal payments,* means that a revisitation of Alberta's early dalliance with scrip, which circulated concurrently with Canadian dollars, is more relevant than ever. The attempt by Albertan authorities to issue scrip 80 years ago would end in failure; most of the paper refused to stay in circulation. Understanding why this happened provides some insights into what sorts of conditions might promote the success of a Greek parallel currency—or its downfall.

Virginius Frank Coe

The best source on Prosperity Certificates is a 1938 survey by Virginius Frank Coe, an American economist who visited Alberta in August 1937, five months after the program had been abandoned. Coe's life is interesting enough to deserve its own tangent. An economist educated at the University of Chicago, Coe would go on to hold a number of important positions in various U.S. government institutions both during and after World War II, including monetary research director at the Treasury Department. This brought him into the orbit of Harry Dexter White, then the Assistant Secretary of the Treasury and the architect of the Bretton Woods agreements. Coe himself was a representative at Bretton Woods and would go on to become secretary of the International Monetary Fund in 1946, nine years after having written his Prosperity Certificate paper.

Readers of Benn Steil's The Battle of Bretton Woods will know that much of the evidence incriminates Harry Dexter White as spying for the Soviets, an accusation White himself denied. The same sources who named White as a Soviet agent also fingered Coe, and in 1952 Coe was forced to resign from his post at the IMF. He would appear in front of the McCarran Committee later that year, pleading the fifth in response to all questions posed to him, and would later face Senator Joseph McCarthy. His passport revoked, and unable to find work in the U.S., Coe headed to China to serve as an adviser to Mao until his death in 1980.

Coe's Prosperity Certificate paper betrays the author as someone with a strong interest in alternative monetary systems. While we can't know for sure if his interest in alternative systems extended as far as being a Soviet mole, we shouldn't let this possibility detract from what is otherwise an excellent account of this early Canadian monetary experiment.

Alberta and Social Credit 

Coe describes an Alberta electorate that is facing the same economic backdrop as Greece's voters did prior to the recent election of Syriza. Just as Greeks had endured seven years of famine prior to the 2015 election, Albertans going into the 1935 election had been beset by seven years of distress associated with low farm prices and bad crop yields. The incumbent United Farmers of Alberta government was not willing to implement the more drastic policies that the Albertan electorate demanded, says Coe. Into the void stepped William Aberhart, a pastor and newly-recruited believer in the tenets of Social Credit. Dreamt up by British engineer C.H. Douglas, the idea behind Social Credit was to create a more equal society by augmenting consumers' purchasing power via the payment of a national dividend. Aberhart formed the Alberta Social Credit party in 1935 and won the election a few months later. In electing Syriza, the Greeks, like the Albertans before them, have entrusted their future to a party of political novices.

Reading Coe, one gets the sense that the Aberhart government stumbled into Prosperity Certificates rather than purposefully selecting them as a policy. Gesell's dated stamp scrip was a rival monetary reform to Social Credit, not a complement. Why turn to a non-Social Credit policy? It seems that several months after coming to power, the new Social Credit government was already splintering as one faction had grown impatient with Aberhart's inability to implement economic changes. Coe, speculating that the decision to implement dated stamp money was a token gesture to demonstrate forward momentum and heal internal rifts, says that "any one of a number of plans would have done as well." If a non-Social Credit monetary scheme such as Gesell money were to fail, at least a Social Credit policy option still had a kick at the can. The implication that the government didn't put much thought into the design of the certificates finds some confirmation in the fact that the Free-Economy League, an organization formed by Gesell, published a criticism of the Alberta government's procedure for creating Prosperity Certificates and predicted their failure.

How the certificates worked

Here's how Alberta's stamp scrip worked. In early August 1936, when the program debuted, an unemployed Albertan was paid, say, a $1 certificate for each $1 worth of road maintenance work rendered. This certificate was to be redeemed by the Alberta government two years hence, or in August 1938, for $1 in Canadian dollars. However, redemption required that the certificate have 104 stamps affixed to it (see figure above). Each week during that two year period, the owner of the certificate was to buy a government stamp for 1 cent from an approved stamp dealer and glue it to the note.

The necessity of buying stamps created a fairly onerous fee on cash holdings. As such, any laborer who received the scrip from the government was unlikely to hoard it, preferring instead to spend it on, say at a retailer, who in turn would only accept scrip as payment for goods and services if the correct number of stamps has been affixed. In order to avoid the cost of buying the next weekly stamp in order to keep the scrip current, the retailer themselves would quickly offload it to their suppliers and so on.

The 1 cent stamp fee was collected by the Alberta government and held as a reserve for redemption in two years. With 104 cents being collected over each $1 certificate's life time, this meant that the scheme was entirely self financing. The extra four cents represented a profit to the government.

Failure

We know that the Prosperity Certificate scheme didn't work. The certificates began to be paid to unemployed Albertans in August 1936 for roadwork rendered in July. According to Coe, the maximum amount of outstanding certificates in circulation in August and early September was $239,391 (around $9 million in current dollars). However, by mid-September 1937, just one month after the program's debut, over 60% of the certificates outstanding, or $144,280 out of $239,391, had ceased to circulate.

Where had they gone? The government now held them. The reason for this development was a last minute decision by Aberhart to offer monthly redemption of certificates at par in Dominion currency (i.e. $1 in certificates for $1 in Canadian bills). This short-circuited the original two-year life of the certificates. Rather than continuing to pass the scrip along to the next Albertan, Albertans leapt at the government's offer and converted en masse when the first redemption date presented itself in early September.

In the end, the government might as well have paid for work rendered using Canadian dollars, since the net effect of paying in either Certificates or Canadian dollars was the same. As Coe says, "the dated stamp scrip was in the end little more than a small nuisance." Subsequent issues of scrip were small relative to the original August 1936 issue and the government officially ended the program in April 1937.

"The problem of the wholesalers"

In the planning stages of the program, government officials ran into what Coe refers to as the "problem of the wholesaler." The first to receive the certificates would be farmers on relief, who in turn would make payments to retailers. The payments by retailers would primarily flow to Albertan wholesalers whose dominant payments were to manufacturers and others outside the province. However, those outside the province would not accept Prosperity Certificates, requiring instead hard currency, or Canadian dollars. The Albertan wholesaler would be left holding the bag, so to say, having acquired the entire issue of Prosperity Certificates with no outlet. According to Coe, wholesalers and large retailers were vocal in their opposition to the plan, which they expressed through trade associations and in the press.

One way of solving the wholesalers' problem would have been to establish an exchange market such that wholesalers could sell certificates in order to buy the necessary hard currency and thus fund out-of-Province imports. Banks would normally be an important party to the creation of such a market. Irving Fisher, who wrote a book on stamp scrip, entitled one paragraph "Have at Least one Bank." But the banks who operated in Alberta refused to participate in the Prosperity Certificate scheme—no wonder given that one of the Social Credit party's planks advocated the removal of the "banking monopoly" on the issuance of credit. The tenets of Social Credit thus interfered with the execution of Gesell money, impeding the latter's success.

Even if such a market were to be created, chances are that it would have priced the Certificates at a large discount to Canadian dollars given the onerous fee on certificates relative to Canadian notes and the inferior credit of their issuer. After all, by then the Alberta government had defaulted on its international obligations whereas the Federal government's credit was still good. Such a discount would have been at odds with the Alberta government's policy of using a dollar's worth of certificates to buy one Canadian dollar's worth of labour. If the certificates were trading at 69 cents on the dollar in the wholesale market, workers paid in scrip would be loath to accept them at face value, for if they did, they would probably have problems passing them off at retailers for that amount.

In the end, the government's solution to the problem of the wholesalers was to allow wholesalers (and even retailers) to benefit from free monthly redemption at par. As I noted earlier, this resulted in most of the certificates being returned for redemption just a few weeks after having been issued.** Rather than bad money driving out the good, a garbled version of Gresham's Law had taken hold in Alberta, which Coe describes thusly: "Bad money obviously does not drive out good money when the government is willing to redeem the bad money in good money."

This garbled version of Gresham's law is a phenomenon I've described before to explain a number of monetary puzzles including the failure of the Susan B. Anthony dollar, the European Target2 bank runs of 2011-12, the proliferation of credit cards, and the zero-lower bound problem. See here and here.

What about Greece?

Alberta in 1936 and Greece in 2015 are in similar situations. Both are non-currency issuers within a larger monetary zone, in Alberta's case the Canadian dollar zone and in Greece's case the Eurozone. Both have awful credit. Neither is part of a larger fiscal union. In Greece's case, the mechanism hasn't yet been created whereas in Alberta's case, the Social Credit party was at such odds with the Federal government and the rest of Canada that it could not expect much help.

I'd argue that anyone planning to introduce a Greek parallel currency to circulate alongside euros faces the same problem that Alberta faced; the so-called problem of the wholesalers. If the Greek government starts to pay employees and contractors in Greek parallel IOUs denominated in euros, and employees buy stuff at stores with those IOUs, and stores purchase inventory from wholesalers, these wholesalers will need a mechanism to offload their parallel note surpluses in order to get euros to buy foreign imports. The IOUs can either find their own price, in which case they will most likely trade at a large and varying discount to euros, or the Greek government can offer one-to-one convertibility. They can do this by either redeeming IOUs directly for euros or allowing one euro worth of taxes to be paid with an equivalent number of IOUs.

Neither solution is ideal. If the IOUs trade at a variable discount to euros, then their ability to serve as a competing medium of exchange will suffer. People always prefer to trade using the medium in which a nation's prices are expressed, or, put differently, the medium which functions as a unit of account. For example, people see benefit in the fact that one euro will always discharge a euro's worth of Greek debt or a buy a euro's worth of Greek olive oil. But as long as Greek IOUs trade at a varying discount to euros, it is impossible to know ahead of time how many IOUs will discharge a euro's worth of debt or buy a euro's worth of oil, given that the euro will surely remain Greece's unit of account. This would hinder the IOU's ability to function as a currency. The fact that people prefer to accept stable exchange media in trade to unstable media is one of the reasons that bitcoin hasn't caught on.

So rather than serving as a competing medium of exchange, the parallel IOUs will probably function as illiquid and highly risky speculative fixed income securities. In order to compensate recipients of IOUs for this lack of liquidity, the Greek government will have to issue the IOUs at a larger discount to par than they would for an otherwise liquid equivalent, thus increasing the government's financing costs.

This lack of liquidity militates against one of the key selling points of a Greek parallel unit, which is to finance the government by displacing some of the existing circulating medium of exchange, euros, from citizens' wallets. Preferably, unwanted euros would trickle back to the European Central Bank to be cancelled, reducing the ECB's seigniorage but augmenting the seigniorage of the Greek state as Greek IOUs rush in to fill the void. However, if the new Greek parallel unit cannot compete with the euro's liquidity, then there will be very little 'space' for Greek IOUs to occupy in Greek portfolios, and little relief for beleaguered government finances.

If the Greek government tries to promote the liquidity of its parallel currency by having the units trade at a fixed one-to-one rate with euros, then the same garbled version of Gresham's Law that took hold in Alberta would overwhelm Greece. In Coe's words, the Syriza government's willingness to buy bad money, or parallel currency units, from the public with good money, or euros, will promote mass conversion into euros and thereby drive all the bad money from circulation. Greek parallel units will cease to exist.***

In sum, anyone planning a Greek parallel currency faces a conundrum. In order to pay its bills the government can do little more than introduce a volatile asset that trades at varying discount to euros. This asset's volatility and relative illiquidity won't make it very popular with its recipients. An attempt to render that asset more acceptable in trade by setting a one-to-one conversion rate to the euro will result in a short-circuiting of the scheme as everyone races to redeem IOUs. The issuance of parallel currencies seems like a hard battle to win.



*There are a number of plans including that of Biagio Bossone & Marco Cattaneo, Thomas Mayer, and Robert Paranteau
** Compounding the problem was that redemption at face value put a premium upon redemption, says Coe. "The holder who redeemed received face value; the person who did not redeem ran the risk of losing 1 per cent of the face value if he failed to pass the certificates within the next few days, and more for longer periods. This premium placed upon redemption could only have been eliminated by redeeming the certificates at a discount of more than 1 per cent-say, 2 or 3 per cent." So the government accidentally created an even greater incentive for certificate owners to redeem.
*** This is particularly damaging in Greece's case at will result in a perpetual draw down in the state's euro balances. These reserves are vital since the Greek government needs to service its (existing or renegotiated) Euro debts to the IMF and pay external suppliers, and can only do so with hard currency.

Fedwire transactions and PT vs PY

Milton Friedman's alleged license plate, showing the equation of exchange

The excruciatingly large revisions that U.S. first quarter GDP growth underwent from the BEA's advance estimate (+0.1%, April 30, 2014) to its preliminary estimate (-1.0%, May 29, 2014) and then its final estimate (-2.9%, June 25m, 2014) left me scratching my head. Isn't there a more timely and accurate measure of spending in an economy?

One interesting set of data I like to follow is the Fedwire Fund Service's monthly, quarterly, and yearly statistics. Fedwire, a real time gross settlement interbank payment mechanism run by the Federal Reserve*, is probably the most important financial utility in the U.S., if not the world. Member banks initiate Fedwire payments on their own behalf or on behalf of their clients using the Fedwire common currency: Fed-issued reserves. Whenever you wire a payment to another bank in order to settle a purchase, you're using Fedwire. Since a large percentage of U.S. spending is transacted via Fedwire, why not use this transactions data as a proxy for U.S. spending?

Some might say that using Fedwire data is an old-fashioned approach to measuring spending. Irving Fisher wrote out one of the earliest versions of the equation of exchange, MV=PT, where T measures the "volume of trade" or "real expenditure" and P is the price at which this trade is conducted. Combined together, PT amounts to the sum of all exchanges in an economy. More specifically, Fisher's T included all exchanges of goods where his chosen meaning for a good was broadly defined as any sort of wealth or property. That's a pretty wide net, including everything from lettuce to publicly-traded equities to land.

Practically speaking, Fisher wrote that it was "utterly impossible to secure data for all exchanges" and therefore his statistical approximation of T was limited to the quantities of trade in 44 articles of internal commerce (including pig iron, rice, hogs, boots & shoes), 23 articles of import and 25 of export, sales of equities, railroad freight carried, and letters through the post office. This mishmash of items included everything from wholesale goods to securities to and consumption goods. Using Fedwire transactions to track total spending is very much in the spirit of Fisher, since any sort of transaction can be conducted through the interbank payments system, including financial transactions.

Nowadays we are no longer taught the Fisherian transactions version of the equation of exchange MV=PT but rather the income approach, or MV=PY. What is the difference between the two? Y is a much smaller number than T. This is because it represents GDP, or only those goods and services that are qualified as final, where "final" indicates items bought by a final user. T, on the other hand, includes not only the set of final goods and services Y but also all spending on second hand goods, stocks and bonds, existing homes, transfer payments, and more. Whereas GDP measures final goods in order to avoid double counting, T measures final and intermediate goods, thus counting the same good twice, thrice, or even more if the good changes hands more often than that.

A good illustration of the difference in size between Y and T is to chart them. The total yearly value of Fedwire transactions, which are about as good a measure of PT that we have (but by no means perfect), exceeds nominal GDP (or PY) by a factor of 40 or so, as the chart below shows. Specifically, nominal GDP came in at $17 trillion or so in 2013 whereas the total value of Fedwire transactions clocked in at $713 trillion.




So why do we focus these days on PY and not Fisher's PT? We can find some clues by progressing a little further through the history of economic thought to John Keynes (is it a travesty to omit his middle name?). In his Treatise on Money, Keynes was unimpressed with Fisher's cash transactions standard, as he referred to it, because PT failed to capture the most important human activities:
Human effort and human consumption are the ultimate matters from which alone economic transactions are capable of deriving any significant; and all other forms of expenditure only acquire importance from their having some relationship, sooner or later, to the efforts of producers or to the expenditure of consumers.
Keynes proposed to "break away from the traditional method" of tabulating the total quantity of money "irrespective of the purposes on which it was employed" and focus instead on the narrow range of trade in current consumption and investment output. Keynes's PY measure (the actual variables he chose was PO where O is current output) would be a "more powerful instrument of analysis than their predecessor, when we are considering what kind of monetary and business events will produce what kind of consequences."

And later down the line, Milton Friedman, who renewed the quantity theory tradition in the 1950s and 60s, had this to say about the shift from PT to PY:
Despite the large amount of empirical work done on the transactions equations, notably by Irving Fisher and Carl Snyder ( Fisher 1911 pp 280-318, Fisher 1919, Snyder 1934), the ambiguity of the concept of "transactions" and the "general price level", particularly those arising from the mixture of current and capital transactions—were never satisfactorily resolved. The more recent development of national income accounting has stressed income transactions rather than gross transactions and has explicitly and satisfactorily dealt with the conceptual and statistical problems of distinguishing between changes in prices and changes in quantities. As a result, the quantity theory has more recently tended to be expressed in terms of income rather than of transactions
So there are  evidently problems with PT, but what are the advantages? Assuming we use Fedwire transactions as the proxy for PT (and again, Fedwire is by no means a perfect measure of T, as I'll go on to show later) the data is immediate and unambiguous. It doesn't require hordes of government statisticians to laboriously compile, recompile, and check, but arises from the regular functioning of Fedwire payments mechanism. There are no revisions to the data after the fact. And rather than being limited to periods of time of a month or a quarter, there's no reason we couldn't see Fedwire data on a weekly, daily, or even real time level of granularity if the Fed chose to publish it.

Even Keynes granted the advantages of PT data when he wrote that the "figures are available promptly without the necessity for any special calculation." In Volume II of his Treatise, he took U.S. "bank clearings" data (presumably Fedwire data), and tried to remove those transactions arising from financial activity by excluding New York City, the nation's chief financial centre, thus arriving at a measure of final spending that came closer to PY.

What are the other advantages of PT? While PT counts second-hand and existing sales, might that not be a good thing? Nick Rowe, writing in favour of PT, once made the point that it's "not just new stuff that is harder to sell in a recession; it's old stuff too. New cars and old cars. New houses and old houses. New paintings and old paintings. New furniture and antique furniture. New machine tools and old machine tools. New land and old land." As for the inclusion of financial transactions, anyone who thinks asset price inflation or deflation is an important property of the economy (Austrians and Austrian fellow travelers no doubt) may prefer PT over PY since the latter is mute on the subject.

I'd be interested to hear in the comments the relative merits and demerits of PY and PT. Why don't the CNBC talking heads ever mention Fedwire, whereas they can spend hours debating GDP? Why target nominal GDP, or PY, when we can target PT?

For now, let's explore the Fedwire data a bit more. In the figure below I've charted the total value of Fedwire transactions (PT) for each quarter going back to 1992. I've overlaid nominal GDP (PY) on top of that and set the initial value of each to 100 for the sake of comparison.



It's evident that the relative value of Fedwire transactions has been growing faster than nominal GDP. However, the financial crisis put a far bigger dent in PT than it did PY. Only in the last two quarters has PT been able to break to new levels whereas nominal GDP surpassed its 2008 peak by the second quarter of 2010. Is the financial sector dragging down PT? Or maybe people are spending less on used goods and/or existing homes?

Fedwire data is further split into price and quantity data. Below I've plotted the number of transactions, or T, completed on Fedwire each quarter. On top of that I've overlaid real GDP, or Y. The initial value of real GDP has been set to 16.6 million, or the number of transactions completed on Fedwire in 1992.



After growing at a relatively fast rate until 2007, the number of transactions T being carried out on Fedwire continues to stagnate below peak levels. In fact, last quarter represented the lowest number of transactions since the first quarter of 2012, a decline that coincided with the atrocious first quarter GDP numbers.

Finally, below I've plotted the average value of Fedwire transfer by quarter. On top of that I've overlaid the GDP deflator. To make comparison easier, I've taken the liberty of setting the initial value of the deflator at the 1992 opening value for Fedwire transaction size.



As the chart shows, the average size of Fedwire transfers really took off in 2007, peaked in late 2008 then stagnated until 2013, and has since re-accelerated upwards. In fact, we can attribute the entire rise in the quarterly value of transactions on Fedwire (the second chart) to the growth in transaction size, not the quantity of transactions. Fedwire data is telling us that inflation of the PT sort has finally reemerged.

A few technical notes on the Fedwire data before signing off. As I've already mentioned, Fedwire provides a less-than complete measure of PT. To begin with, it doesn't include cash transactions (GDP does, or at least those that have been reported). This gap arises for the obvious reason that cash transactions aren't conducted over Fedwire. Nor do cheque transactions appear on Fedwire, or at least they do so only indirectly. Check payments are netted against each other and canceled, with only the final amounts owed being settled between banks via Fedwire, these settlements representing just a tiny fraction of the total value of payments that have been conducted by check over any period of time.

The same goes for securities transactions. Fedwire data underestimates the true amount of financial transactions because trades are usually netted against each other by an exchange's clearing house prior to final settlement via Fedwire. The transfer of reserves that enables the system to settle represents a small percent of the total value of trades that have actually occurred.

Another limitation is that Fedwire data doesn't include wire payments that occur on competing payment systems. Fedwire isn't a monopoly, after all, and competes with CHIPS. I believe that once all CHIPS payments have been cleared, final settlement occurs via a transfer of reserves on Fedwire, but this final transfer is a fraction of the size of total CHIPS payments. And finally, payments that occur between customers of the same bank are not represented in the Fedwire data. This is because these sorts of payments can be conducted by a transfer of book entries on the bank's own balance sheet rather than requiring a transfer of reserves.

I'm sure I'm missing other reasons for why Fedwire data undershoots PT, feel free to point them out in the comments. Do Fedwire's limitations cripple its value as an indicator PT? I think there's still some value in looking at these numbers, as long as we're aware of how they might come up short.

2. A paper exploring UK CHAPS data,the British equivalent to Fedwire: Income and Transactions Velocities in the UK

* 'Real time' means that payments are immediate and not subject to delay, while 'gross settlement' indicates that payments are not grouped together for processing but submitted individually upon being entered. Fedwire gets its name from the beginning of the last century, when payments were carried out over the wires, or the telegraph system.

It was the best of times, it was the worst of times



You may know by now that the final revision of U.S. first quarter GDP revealed a shocking 2.9% decline while its mirror image, gross domestic income (GDI), was off by 2.6%.

As Scott Sumner has pointed out twice now, the huge decline in GDI is almost entirely due to a fall in corporate profits. Whereas employee compensation, the largest contributor to GDI, rose from $8.97 to $9.04 trillion between the fourth quarter of 2013 and the first quarter of 2014, corporate profits fell from $2.17 to $1.96 trillion (see blue line in the above chart) This incredible $198 billion loss represents a 36% annualized rate of decline!

A number of commentators have pointed out the difficulty in squaring this data bloodbath with reality. After all, Wall Street has not been announcing 36% quarter on quarter profit declines. Rather, earnings per share growth has been pretty decent so far this year. If earnings were off by so much, then why are equity markets at record highs? Why have there been no layoffs? It's hard to believe that a bomb has gone off when there's no smoke and debris. Investors are patting themselves down to make sure they had no wounds or broken body parts and, coming up clean, are shrugging and buying more stocks.

I'm going to argue that the odd disjunction between the numbers and reality may have arisen due to something called money illusion. We live in a historical-cost accounting world in which stale prices are used as the basis for much of our profit and loss calculations. But the gunshot rang out in a different universe, one in which accountants rapidly mark costs to market. At some point we in the historical-cost world will feel the repercussions of the gunshot since everything is eventually marked to market. For now, however, no one seems to have noticed because we're all caught up in an the illusion created by accountants focused on the ghost of prices past.

More specifically, the folks at the Bureau of Economic Analysis who compile GDI report a different corporate profit number than the profit numbers being bandied around on Wall Street during earnings season. Wall Street profits are by and large paid out after depreciation expenses, and these have been accounted for on a historical-cost basis. This is the red line in the above chart. The BEA's number, represented by the blue line in the chart above, represents the profits that remain after depreciation expenses have been marked to market. The choice between mark-to-market depreciation accounting and historical-cost accounting can result in large differences in bottom-line profit, as the last data point in the chart illustrates.

For instance, consider a manufacturing company that earns revenues of $100 per year from a machine that it bought for $600. It depreciates the machine by $60 each year over 10 years, earning a steady $40 in profits ($100 - $60). Now imagine that all over the world machines of this type are suddenly sabotaged so that, due to their rarity, the cost of repurchasing a replica doubles to $1200. If the manufacturing company uses historical cost deprecation, it will continue to bring in revenues of $100 a year, deducting the same $60 in depreciation to show $40 in earnings. All is fine in the world. But if the firm uses mark-to-market depreciation, the cost of using up the machine will now reflect the true cost of replacing it: $120 a year ($1200/10 years). Subtracting $120 from the annual $100 in revenues means the company is losing $20 a year, hardly a sign of health.

It's easy to work out an example that shows the opposite, how a glut in machinery supply (which would drive the replacement cost of the machine down) is quickly reflected in a dramatic improvement in earnings after mark-to-market depreciation expenses, but earnings after historical-cost depreciation show nothing out of the ordinary.

Thus we can have one profit number that tells us that all is fine and dandy, and another that indicates the patient is on death's door. An individual's perception of the situation depends on which universe they live in, the historical cost universe or the mark-to-market one. The GDI explosion has gone off in the latter (the BEA uses a mark-to-market methodology), but since we experience only the former (the Wall Street earnings parade is entirely a celebration of historical-cost earnings per share data) we haven't really felt it... yet.

Yet? Even a company that lives in a historical cost accounting universe will eventually have to face the market price music. Imagine our sabotage example again. If our company uses mark-to-market accounting, it will immediately know it is facing a problem since its $100 revenue stream is failing to offset the $120 cost of machinery depreciation. However, if it uses historical cost accounting then our company continues to enjoy what it perceives to be a revenue stream that more than offsets its historically-fixed $40 cost of machinery. However, once that machine inevitably breaks down and needs to be replaced with a $1200 machine, a new historical cost base will be established and depreciation will suddenly rise to $120. Several quarters too late the company will realize that it is now operating in the red. Had it marked deprecation to market, that realization would have come much sooner.

If I had to speculate, here's a more detailed story about the last quarter. US corporate revenues were particularly underwhelming between Q4 2013 and Q1 2014 due to the cold weather. At the same time, we know that a number of government stimulus acts that had introduced higher than normal historical cost depreciation allowances (this allows firms to protect their income from taxes) were rolling off. Flattish revenues were therefore offset by smaller deprecation costs, resulting in a decent bump to headline earnings numbers, as the red line in the chart shows. Everything looked great to majority of us who inhabit the historical cost accounting universe.

However, mark-to-market depreciation accounting used by the BEA strips out the effect of the expiring depreciation allowances, thereby removing the bump. The combination of flattish revenues and higher market-based depreciation expenses (perhaps due to some inflation in the cost of capital goods) would have conspired to create a fall in the blue earnings series, and therefore a groaningly bad quarter in our mark-to-market universe.

In any case, the crux of the issue is that Wall Street's headline numbers indicate that corporate America did a better job in the first quarter of 2014 generating the cash necessary to replace worn out capital than it did in Q4 of 2013. The BEA numbers are telling us the opposite, that corporate America did a poorer job of covering the costs of wear & tear. Neither of the two numbers is wrong per se, but as I've already point out in my example, mark-to-market methodology is the first to reveal problems while historical cost accounting will follow after a lag.

As I've already hinted, the fact that Wall Street hasn't yet noticed that it just lived through a miserable quarter can be attributed to money illusion: a phenomenon whereby people focus on nominal rather than real values. In this specific instance, investors are so obsessed with headline changes in earnings that they fail to adjust that number for the true cost of using up machinery. Irving Fisher himself described a version of this mistake in his book The Money Illusion:
...during inflation the cost of raw materials and other costs seem to be lower than they really are. When the costs were incurred the dollar was worth more than it is later when the product is sold, so that the dollars in the original cost and the dollars in the later sale are not the same dollars. The manufacturer is deceived just as was the German shopkeeper or the Austrian paper manufacturers who thought they were making profits.
How likely is it that Wall Street, full of so many bright individuals, is being fooled by money illusion? It's not inconceivable. Even Scott Sumner volunteers that he doesn't believe the BEA's numbers due to soaring stock prices and strong earnings, thus falling prey to that very same affliction that serves as his blog's namesake. Money illusion can happen to the best of us.

Ghost Money: Chile's Unidad de Fomento

Santiago skyline

This post continues on the topic of the separation of the medium-of-exchange function of money from the unit-of-account function. My previous post discussed how the medieval monetary order was characterized by both a medley of circulating coins and one universal £/s/d unit of account. This post introduces a modern example of medium-unit divergence: the Chilean peso and Chile's Unidad de Fomento. I'll explain how the Chilean system works and end off by asking some questions about the macroeconomic implications of this separation, specifically what happens at the zero lower bound.

Like most modern currencies, the peso is issued by the nation's central bank; the Banco Central de Chile. Local banks offer peso-denominated chequing and savings accounts. Chileans use these pesos as the nation's medium-of-exchange. They pay their bills with pesos, settle rent with it, and buy food with it.

The differences between Chile's monetary system and those of other nations only emerges when we begin look at the unit in which goods are priced. Most nations have one unit-of-account, but Chile has two. While many Chilean prices are expressed in terms of the peso, or P, a broad range of prices are expressed in an entirely different unit, the Unidad de Fomento, or UF. Real estate, rent, mortgages, car loans, long term gov securities, taxes, pension payments, and alimony are all priced using UF. As examples, this real estate website sets prices in UF terms, and this car rental business levies insurance in UFs. On the other hand, wages, consumer good prices, and stock prices are expressed in peso terms.

So what is the UF? The UF was introduced in 1967 by the Chilean government, though it only came into wide use as a unit-of-account in the 1980s. There are no UF coins or notes circulating in the Chilean economy. Rather, the Unidad de Fomento exists as a purely abstract, or indexed, unit-of-account, totally divorced from any media-of-exchange. Goods and services quoted in terms of the UF can only be purchased with an entirely different medium — pesos.

The UF is defined as the amount of currency units, or pesos, necessary for Chileans to buy a representative basket of consumer goods. The amount of pesos in one UF, or the peso-to-UF exchange rate, is calculated daily, and is published on the Banco Central's website. The daily value is interpolated from the previous month's consumer price index, or the Indice de Precios al Consumidor (IPC). If you go to this website, you can see the current peso-to-UF rate and how it has been adjusted over the last week.

This all sounds quite odd, so let's use an example to get a better idea for how the system functions. When a Chilean seller prices something in UF, they are indicating that they expect to receive a fixed quantity of CPI basket-equivalents as payment. For instance, say that a landlord advertises an apartment in downtown Santiago at a monthly rate of 10 UF. A potential renter, curious about the price, checks the UF-to-peso exchange rate at the central bank's website. He sees that today's rate stands at 23,000. Using a cellphone app (in real life, the rate will probably not be a convenient round number), he multiplies 10 UF x 23,000 P/UF to arrive at the current monthly rate in pesos, or 230,000P (this is about US$450). Deciding that the price is good, the renter signs a lease and starts to pay UF-denominated rent each month in pesos.

Say that the Banco Central adopts an easy money policy and six months later the Chilean peso's purchasing power has fallen by around 10%. Rent is still priced at 10 UF. But now the peso content of the UF has risen —after all, it takes about 10% more pesos to buy the same consumer basket. The computed rate on the central bank's website is now 25,000 P/UF. The monthly amount in pesos that the renter must make out to the landlord now comes out to 250,000P (10UF x 25,000 P/UF), up from 23,000. However, while the rent payment is nominally higher, the payment's UF value is constant. In other words, the transaction represents the exact same quantity of CPI baskets as six months before.

It works the same way when the with a tight money policy. Imagine a 10% peso deflation. The UF sticker price stays constant while the conversion rate to pesos on the central bank's website falls by 10%. Rent is nominally lower in peso terms but in terms of representative consumer baskets it has stayed constant.

The UF/P system is similar in many ways to a partially dollarized economy in which the US dollar has been adopted as the unit in which to price long term contracts while the local currency is used to price current goods and services. What makes Chile different from partially dollarized economies is that the dollar tends to circulate along with the local currency as a medium-of-exchange. Thus there are two different units-of-account corresponding to two different media-of-exchange. Chile's UF, on the other hand, is a purely abstract unit with no corresponding medium of its own.

Irving Fisher was skeptical of medium-unit divergence and declared so in his 1913 paper The Compensated Dollar:
Not only would the multiple standard necessitate much laborious calculation in translating from the medium of exchange into the standard of deferred payments, and back again but, if, as has been suggested, the employment of a multiple standard were at first optional, the result would be that many business men whose prosperity depended on a narrow margin between their expenses and receipts would be injured rather than benefited by having one side of their accounts predominantly in the actual dollar and the other in the ideal unit.
Fisher went on to propose his compensated dollar scheme, which was essentially a combined unit-of-account/medium-of-exchange dollar. The real purchasing power of the compensated dollar would stay constant over time, much like the UF/peso combination, but without the necessity of imposing the laborious calculations involved in medium-unit divergence. That Chileans did choose to adopt a somewhat laborious mechanism that involves conversion from/to pesos to/from the ideal UF demonstrates the degree to which they were willing to free themselves of the burdens imposed by the 1970s inflation of the peso. The practice of publishing the UF-to-peso rate on a daily basis—which began in 1977— may have also encouraged UF adoption. Prior to then, the UF had only been calculated monthly.

While the idea of separating the unit from the medium is not a common one, when it does arise it tends to have been inspired by the desire to avoid the deleterious effects of inflation. Widespread use of the UF, as pointed out earlier, came about as a response to 500%+ peso inflation of the 1970s. Robert Shiller, the most vocal modern advocate of unit/medium separation, has also been motivated by concerns over the deleterious effects of inflatio. Shiller believes that because people tend to succumb to money illusion when dealing with inflationary episodes, the adoption of indexed units-of-account may be the most palatable way to reduce the problem.

Just as interesting, however, is the idea of separating the unit-of-account and medium-of-exchange to help cope with deflationary episodes and the zero-lower bound problem

First, let's set up a hypothetical scenario without the UF and a combined peso unit-of-account and medium of exchange. Say the Chilean economy suddenly collapses. Pessimistic Chileans expect to earn a negative return on projects and investments. Peso cash provides a superior return in this environment since it pays 0%—hardly great, but 0% is better than -x%! Peso prices need to fall dramatically in order to restore equilibrium. Put differently, the value of the peso needs to rise to a level at which it is expected to decline at the same rate as all other projects and investments. Yet peso-denominated sticker prices are rigid, preventing the necessary adjustment. What should be a short period of sharp adjustment turns into a long painful period of high unemployment and idle resources.

Now let's assume that all prices are expressed in UF while actual transactions are conducted in pesos. The same shock hits the Chilean economy. Once again the negative yield on projects and investments is overwhelmed by the 0% yield on peso cash. Peso prices need to fall dramatically in order to equilibrate the peso's return with all other yields. As before, sticker prices are rigid.

Here's the difference between our first and second scenarios. In a world with an ideal unit-of-account and no related medium-of-exchange, it really doesn't matter that prices can't adjust. This is because prices are no longer expressed in terms of 0%-yielding peso cash. Rather, they are expressed in terms of UF. Because the UF lacks a physical counterpart, there are no equivalent UF instruments that might also hit the zero-lower bound. The peso's outsized 0% return relative to all other negative yielding assets, which before was the root of the problem, will be quickly equilibrated as the peso-to-UF exchange rate published on the central bank's website jumps higher.

So a shock to an economy in which a combined medium-of-exchange and unit-of-account prevails can quickly become a tragedy. The 0% nature of the former interferes with the stickiness of the latter. But when the medium-of-exchange is divorced from the unit-of-account, the 0% nature of the former will quickly be resolved since stickiness is now in terms of an ideal unit, and not in terms of pesos.

Medium/unit separation, it would seem, could be yet another foolproof way of escaping deflation and the zero-lower bound.

Aggressive US monetary policy... in Iran

Whenever we think of US monetary policy we usually think of the Fed. There's another side to US monetary policy, and its probably just as significant.

Being part of the worldwide US dollar clearing & settlement system means having access to the world's most liquid payments medium: the US dollar-denominated bank deposit. As long as a nation's banks are connected to this network, goods that are produced in that nation will be infinitely more saleable. On the other hand, being cut off from it means that the same goods will be a lot tougher to move. The Iranian monetary blockade illustrates the US Treasury's ability to use banishment from the USD network, or the threat thereof, to exert incredible influence over the world.

To see how this works we've got to understand how the worldwide US dollar deposit clearing system functions. Let's start at the periphery of the network. An Iranian bank (call it "Persian Bank") lets Iranians keep USD deposits and transfer them amongst each other. These trades clear on the books of Persian Bank. The US Treasury is powerless to prevent Persian Bank from doing a local USD business.

What happens if an Iranian customer want to receive USD from a French company to pay for Iranian oil?

To facilitate this transaction, Persian Bank needs to set up a what is called a correspondent banking relationship with a non-Iranian bank at the centre of the network. A Persian Bank exec flies to London and opens a USD account at "London Bank", a large multinational bank. As long as our French company's bank   we'll call it "Paris Bank" also has a USD account at London Bank, then the entire transaction can be conducted on London Bank's books. Paris Bank simply tells London Bank to transfer the appropriate quantity of USD deposits from its account to Persian Bank's account. Back in Iran, Persian Bank credits the USD account of the Iranian customer. At the same time, Paris Bank debits the USD account of the French company. The oil can now be sent.

Here's how the monetary blockade works. The US Treasury issues an ultimatum to London Bank. There's nothing that we can do to stop you from clearing USD trades on your books for Iranian banks, the Treasury says, but if you do so, you'll have to close your accounts at "New York Bank", a large US institution.

London Bank is in a pickle. The reason it keeps an account at New York Bank is so that it can transact the US side of its business. Assume that US importers keep their accounts at New York Bank and debit these accounts to pay for imported goods. London Bank's account at New York Bank allows it to settle trades between US importers and its European exporting clients. If London Bank is forced to close its New York Bank account, it can't partipate in US trade anymore.

For London Bank, the choice is easy. It will cease dealing with Iranian banks altogether since the cost of losing US business is far larger than the cost of losing Iranian business. The upshot is that in threatening to banish London from the US, the US Treasury can force London to banish Iran from the worldwide USD network.*

The removal of Iranian banks from the international USD clearing system has meant that it's infinitely tougher for Iranians to sell their crude. To get around the banking blockade, we here stories about Iran reverting to barter. But this has been insufficient to prevent Iran's economy from entering what seems to be recessionary territory.

This certainly jives with monetary theories of the business cycle. Milton Friedman, for instance, wrote that the Great Depression was caused by the Fed providing insufficient liquidity to the banking system. Rather than conduct massive open marker operations, it tightened. As the Depression worsened, we saw the emergence of barter and alternative payment schemes. Even Irving Fisher became an advocate of these systems, publishing Stamp Scrip in 1933. Because it has been caused by a lack of liquidity, Iran's recession is very much a monetary one. It will only get out of the recession if it is able to derive alternate payment schemes that make Iranian products as liquid as before, or if the US lets it back into the worldwide US dollar clearing & settlement network.

*the actual ultimatum given by the US Treasury is not an all-or-none ultimatum. As long as countries show some evidence of having reduced Iranian oil imports, the US Treasury grants a temporary waiver that allows banks in importing nations to continue to settle oil transactions made by Iranian banks. To date, all importers of Iranian oil have complied by reducing imports. This means that the Treasury hasn't had to act on its threat of sanctioning banks that do business with Iranian banks.
