A Tale of Two Countries: Cash Demand in Canada and Sweden
Cash use for payments has been steadily decreasing in many countries, including Canada and Sweden. This might suggest an evolution toward a cashless society. But in Canada, cash in circulation relative to GDP has been stable for decades and has even increased in recent years. By contrast, the cash-to-GDP ratio in Sweden has been falling steadily. What has caused this difference? Are there lessons to be learned from comparing the Canadian and Swedish experiences? -

A Framework for Analyzing Monetary Policy in an Economy with E-money
This paper considers an economy where central-bank-issued fiat money competes with privately issued e-money. We study a policy-setting game between the central bank and the e-money issuer and find (1) the optimal monetary policy of the central bank depends on the policy of the private issuer and may deviate from the Friedman rule; (2) multiple equilibria may exist; (3) when the economy approaches a cashless state, the central bank’s optimal policy improves the market power of the e-money issuer and can lead to a discrete decrease in welfare and a discrete increase in inflation; and (4) first best cannot be achieved.
