Why hasn't Canadian Tire Money displaced the Canadian dollar?

Canadians will all know what Canadian Tire Money is, but American and overseas readers might not. Canadian Tire, one of Canada's largest retailers, defies easy categorization, selling everything from tents to lawn furniture to hockey sticks to car tires. Since 1958, it has been issuing something called Canadian Tire Money (see picture above). These paper notes are printed in denominations of up to $2 and are redeemable at face value in kind at any Canadian Tire store.

Because there's a store in almost every sizable Canadian town, and the average Canadian make a couple visits each year, Canadian Tire money has become ubiquitous—everyone has some stashed in their cupboard somewhere. Many Canadians are quite fond of the stuff—there's even a collectors club devoted to it. I confess I'm not a big fan: Canadian Tire money is form of monetary pollution, say like bitcoin dust or the one-cent coin. I just throw it away.

It's the monetary oddities that teach us the most about monetary phenomena, which is why I find Canadian Tire money interesting. Here's an observation: despite the fact that it is ubiquitous, looks like money, trades at par, and is backed by a reputable issuer, Canadian Tire money doesn't circulate much. Stephen Williamson, a Canadian econ blogger, had an entertaining blog post a few years back recounting unsuccessful efforts to offload the coupons on Canadians. Sure, from time to time we might encounter the odd bar or charity that accepts it, or maybe a corner-store in Wawa. But apart from Canadian Tire stores, acceptability of Canadian Tire money is the exception, not the rule.

Why hasn't Canadian Tire money become a generally-accepted medium of exchange? One explanation is that Canadian law prevents it. Were the government to remove the strict rules that limit the ability of the private sector to issue paper money, bits of Canadian Tire paper would soon be circulating all across the nation, maybe even displacing the Bank of Canada's paper money.

A second hypothesis is that even if the law were to be loosened, Canadian Tire would remain an unpopular exchange medium. Some deficiency with Canadian Tire money, and not strict laws, drives their lack of liquidity. Nick Rowe, another Canadian econ blogger (notice a theme here?), once speculated that this had to do with network effects. Canadians have long since adopted the convention of using regular Bank of Canada-issued notes, and overturning that convention by accepting Canadian Tire money would be too costly. David Andolfatto (not another Canadian econ blogger!), would probably point to limited commitment as the deficiency. IOUs issued by Canadian Tire simply can't be trusted as much as government money, and so they inevitably fail as a medium of exchange.

In support of the first view, which is known in the economics literature as the legal restrictions hypothesis, Neil Wallace and Martin Eichenbaum (yep, another Canadian) recount an interesting anecdote. Back in 1983, competitor Ro-Na (since renamed RONA), a major hardware chain, started to accept Canadian Tire coupons at face value. I've found an old advertisement of the offer below:

RONA advertisement in La Presse, 1983 (source)

Eichenbaum and Wallace say that this is evidence that Canadian Tire money isn't just a mere coupon but readily serves as a competitive medium of exchange among Canadians. After all, if a major store like RONA accepted the coupons, then their acceptance wasn't just particular—it was general.

The story doesn't end there. Here is an interesting 1983 article from the Montreal Gazette:

The article mentions how in retaliation Canadian Tire sought an injunction against RONA to prevent it from accepting Canadian Tire money. We know this tactic must have been somewhat successful since RONA does not currently accept said coupons. Eichenbaum & Wallace slot this into their legal restrictions theory, noting that the injunction was probably motivated by Canadian Tire's desire to comply with legal prohibitions on the private issuance of currency, a damaging law suit helping to inhibit general use of their coupons. Remove these legal restrictions, however, and Canadian Tire would probably not have sued RONA, and usage of Canadian Tire coupons as a medium of exchange would have expanded. Presumably if Tim Horton's took up the baton from RONA and accepted Canadian Tire money, and then Couche-Tard joined in, you'd end up with a new national currency.

So we have two competing theories to explain Canadian Tire money's lack of acceptability. Which one is right? Let's introduce one more story arc. Zoom forward to 2009 when Canadian Tire lawyers sent a notice to a NAPA car parts dealer asking him to stop accepting Canadian Tire money. The reason cited by Canadian Tire: trademark infringement. As the article points out, Canadian Tire Money constitutes intellectual property, and if companies do not sufficiently police their trademarks against general usage, they may lose control of them. For instance, over the years Johnson & Johnson has had to vigorously defend its exclusive rights to the name "Band-Aid." If it hadn't, it might have lost claim to the name in the same way that Otis Elevator lost its trademark on the word "escalator" because the word fell into general use. That the 1983 RONA challenge probably had less to do with currency laws than trademark infringement damages Eichenbaum &Wallace's argument.

The last interesting Canadian factoid is the observation that a number of community currencies circulate in Canada. Salt Spring dollars, a currency issued by the Salt Spring Island Monetary Foundation, located off the coast of British Columbia, is one of these. Other examples include Calgary Dollars and Toronto Dollars. According to Johanna McBurnie, Salt Spring dollars are legal because they are classified as gift certificates. If so, I don't see why the use of Canadian Tire money as a medium of exchange wouldn't fall under the same rubric. This puts the final nail in Wallace & Eichenbaum's argument that restrictions on circulation of competing paper money have prevented broad usage of Canadian Tire paper. Rather, if laws are to blame for the minimal role of Canadian Tire Money's as currency, then it is the company's desire to protect its trademark that is at fault.

That local IOUs like Salt Spring dollars can legally circulate but lack wide acceptance (even in the locality in which they are issued) means we need something like the Nick Rowe's network effects or David Andolfatto's limited commitment to  explain why incumbent paper money tends to exclude competing paper money from circulation. Which isn't to say that Canadian Tire money would never circulate. As Larry White and George Selgin have pointed out, private paper money has circulated along with government paper money in places like Canada. But the bar for Canadian Tire money is probably a high one.

Deep money, the coexistence puzzle, and the legal restrictions hypothesis

WWI Liberty bonds, which according to Neil Wallace circulated alongside Federal Reserve notes [source]

What follows are some thoughts on the coexistence puzzle as well as the folks who find it interesting.

There is plenty of hyperbole over the difference between freshwater and saltwater economists, but one peculiarity that surely distinguishes a freshwater economist from his saltier cousin is that they tend to be interested in the underlying motivations guiding monetary exchange, the so-called microfoundations of money. (Saltwater economists tend to be content with broad assumptions about monetary phenomena). Representatives of the microfounded approach, which includes the blogosphere's own David Andolfatto as well as Stephen Williamson—who has anointed his approach New Monetarism—like to refer to their models as "deep models of money".

One of the classic questions that continues to interest deep money types is the so-called coexistence puzzle. Zero-yielding financial assets like central bank-issued banknotes are "dominated" in terms of rate of return by interest-yielding financial assets created by governments. The puzzle that needs explaining is why these dominated instruments can continue to coexist with the instruments that do the dominating.

A quick answer is that a lower-yielding asset can coexist with the higher-yielding asset because the first is more liquid than the second. In an uncertain world, the stream of liquidity services that an asset provides over its lifetime is a valuable service. An asset that provides a little less income can still be demanded in the marketplace as long as it provides a little more liquidity. Deep money folks would say that my answer is a bit shallow. It avoids exploring both the qualities of the assets being used and the frictions that characterize the world in which those assets trade that might render one asset more liquid than the next.

Let's explore the setup of the coexistence problem in more detail. In a 1982 paper, deep money pioneer Neil Wallace defined the problem thusly; if the government were to issue small denomination bearer bonds, say in units of $5, $10, and $20, and these instruments were to yield interest, just like their larger denomination relatives, why would anyone carry 0% Federal Reserve notes in their wallets when they might own an interest-yielding replica instead? These two instruments shouldn't coexist—cash should be driven out of existence or, if they are to coexist, then bearer bonds should yield no more than the 0% rate on cash.

One aspect of the problem, Wallace noted, was that for some obscure reason, governments typically choose not to issue small denomination bearer bonds. The large denomination size of t-bills and t-bonds inhibits their use in trade, thus preventing at the outset any sort of direct competition between government bonds and zero-yielding cash.

However, Wallace pointed out that this doesn't explain why private issuers don't simply buy high denomination government bonds and create their own government bond-backed small denomination bearer notes. If they did so, Wallace believed that two things might happen. These private issuers, by virtue of paying interest on their notes (more specifically by issuing bearer bonds at a discount to face value and allowing them to appreciate in price till maturity, much like treasury bills) would drive inferior 0% yielding banknotes out of existence so that only interest-bearing notes circulate.

Alternatively, the public would allow privately-issued bearer bonds to circulate at par with existing currency. Par acceptance would mean that private bearer bonds no longer paid interest in the form of a steadily rising price. However, Wallace stumbled upon an interesting side effect of par acceptance: nominal rates on government bonds would have to fall to zero. Why? According to Wallace, arbitrage dictates that as long as the rate on long term government bonds is above zero, competing private issuers will flock to buy those term bonds with which to back their 0% bearer notes, putting upward pressure on bond prices and downward pressure on yields. It makes sense for banks to do so because they earn the spread between the 0% notes that they issue and the interest-yielding bonds they purchase. According to Wallace, the arbitrage window will only be shut when banks have driven long term rates close enough to zero that the the opportunity for excess profits disappears. In a free market, the term structure of interest rates disappears. All we have is a flat yield curve.

Here is Wallace: "Thus, my prediction of the effects of imposing laissez-faire takes the form of an either/or statement; either nominal interest rates go to zero or existing government currency becomes worthless."

Of course in the world we live interest-yielding bearer currencies have not kicked out 0% notes nor have private notes driven long term bond rates to zero. Wallace attributed this to various legal restrictions against banks from entering the small denomination bearer bond line of business. Take away these legal restrictions and he believed that his conclusions followed.

Even if we removed these legal restrictions, I'm not convinced by Wallace's arguments. Given free competition in note markets, I don't think that positive-yielding small denomination bearer bonds (issued either by a private bank or a government) must necessarily drive cash into exile, not do I think their coexistence means that the term structure of interest rates must be flat.

To start with, the necessity of calculating interest payments throws a wrench in the smooth transfer of a bearer asset, a point made by Larry White. Say that the bearer bonds are printed with a $10 face value but sold by the government at a discount to face so that their price appreciates over time until maturity, the capital gain being a stand-in for interest payments. Should someone wish to use their unmatured bearer bond to pay for something, they will have to calculate how much of a discount to face to apply to the bond. Such a calculation imposes a burden on the transactors since it will take time to crunch the numbers or require a costly technology to speed up the process. As White has noted, a $20 note held for one week at 5% interest would yield less than 2 cents. Is it really worth it for a banknote user to take the time and trouble to compute and collect such a small amount?

The interest rate feature of bearer bonds also precludes the simple summations that round numbers allow. An owner of a $10, $5, and $20 bearer bond doesn't have $35 in purchasing power. Rather, discounting the bonds will show that their purchasing power is composed of inconvenient sums like $9.33, $4.89, and $19.60. This makes it harder to know how much purchasing power is in one's wallet prior to going to market, thereby inhibiting the usefulness of bearer bonds as a liquid medium. Carrying around 0% currency which trades at its face value allows for certainty of purchasing power, a feature that may more than compensate for lack of a pecuniary yield.

Even worse, having inconvenient non-round bonds in one's wallet or till makes the process of obtaining or providing change a nightmare. If you buy a $10 bottle of wine with an unmatured bearer bond worth $11.56, what are the odds that the cashier will have a $1.56 bearer bond to give you as change? 0% cash may not offer interest payments, but at least the standardized even denominations in which it is available (combined with small change) allow for hassle-free transactions.

Lastly, all transactions in bearer bonds face capital gains taxes. That means on each exchange, the owner of bearer bonds must fish back into their records to find the original price at which they received the bond, determine the price at which it was sold, compute the profit, and then submit all this information to the tax authority. Payments made with 0% banknotes are not taxed, saving those who choose to transact with banknotes time and energy.

So in a nutshell, the previous factors may explain why interest-yielding small denomination bearer bonds will always be less liquid relative to 0% yielding cash, thus preventing the former from kicking the latter out of circulation.

If Wallace's first point is wrong and the payment of interest on banknotes doesn't drive existing 0% cash out of existence, what about his second prediction? Assuming that privately issued bearer bonds are accepted at par, what prevents profit-hungry banks from issuing 0% bankotes and accumulating interest-bearing bonds, eventually arbitraging bond rates down to zero?

As I've already illustrated, interest yielding instruments (especially large and ungainly ones like t-bills) will always be less liquid than cash. This gives rise to an un-arbitrageable wedge between the yield on cash and that on bonds, or a liquidity premium. Note-issuing private banks eager to earn more spread income may be able to temporarily push rates down through bond purchases. However, at these lower bond rates the marginal bond investor will be dissatisfied. They are now holding an asset that offers the same inferior liquidity return as before but less interest. These investors will sell their bonds, in the process pushing interest rate right back up to so that bonds once gain offer an attractive return on the margin. In short, bond-buying banks can't push long term bond rates down to zero because the rest of the liquidity-buying public won't let them.

But if long term rates won't budge when banks buy them, doesn't that mean that banks can continuously earn excess profits by perpetually issuing 0% notes and purchasing risk-free long term bonds? Free dollar bills left on the floor are, after all, the biggest no-no in economics. This ignores the fact that even if rates don't fall to zero, other costs will rise instead as banks compete to enjoy the spread. Larry White refers to this as non-price competition. It might include any number of costly strategies used to attract note-holders, including longer bank operating hours, more tellers, increased advertising expenses to make notes more trusted, and special engraving of notes to make one's bills more attractive relative to the competitions'. Thse mounting costs will soon counterbalance the fat spread income, thereby reducing the window for excess profits.

So contra Wallace, laissez faire doesn't reduce the risk-free bond yield curve to a flat line. Because liquidity differentials between bonds and notes will continue to exist free market or not, bond rates will always have to provide a sufficiently high nominal interest rate in order to attract holders.

What makes Wallace's conclusion about the yield curve in a free market interesting is its pleasing counter-intuitiveness. Many of the theories that deep money people come up with have this same quality, including one of my favorites: the irrelevance of open market operations, or what some call Wallace Neutrality. Stephen Williamson's odd theory that central bank's need to fight inflation by lowering rates, not increasing them, is in this same tradition, although in this case I think he's probably wrong.

Empirical evidence is the best way to test deep money theories. In the case of Wallace's legal restrictions theory, reality is not kind. For instance, we know that in the 18th and 19th centuries Scottish banks were not burdened by legal restrictions on the issue of notes, yet the Scottish yield curve was not a flat one. Indeed, interest bearing bills-of-exchange circulated freely with notes. Despite dominating notes, bills of exchange did not drive them to oblivion. Makinen and Woodward report on the coexistence of small-denomination interest-paying "bons" in 1920s France with the franc currency, and Wallace himself points to evidence that Liberty bonds circulated concurrently with Fed cash during WWI. (I should note that David Andolfatto is skeptical of these instances since they are commonly associated with periods of fiscal distress.)

As for some of the more modern deep money efforts like Stephen Williamson's, reality remains a hard customer. One wonders how Rudolph Havenstein's tight interest policy would have created the Wiemar hyperinflation, for instance. While I'm being tough on the deep money folk, I want to sign off on a positive note. Figuring out the underlying nature of monetary exchange is no doubt an important endeavor. Anyone who wants to learn more about monetary phenomena and central banking should probably be reading what the deep money people have to say.
