There is wide agreement that currency was not available in conveniently small denominations prior to the 19th century. Here, estimates of the costs of providing and maintaining money (coins) in 15th century Europe and parameterized versions of a matching model of money are used to find the...

Previous work on the denomination structure of currency treats as exogenous the distribution of transactions and the denominations held by people. Here, by way of a matching model, both are endogenous. In the model, trades in pairwise meetings alternate in time with the opportunity to freely...

The separation of a unit of account (UoA) from a medium of exchange (MoE) in the commodity-money system is investigated by considering explicitly a seller¡¯s choice with regard to posting price in terms of either an MoE or a UoA. If the likelihood of debasement of MoE or its rate is high...

Retailers in the Netherlands and the U.K. can charge different prices for a commodity depending on whether cash or a debit card is used as payment, whereas retailers in the U.S. generally cannot. These two types of economies with and without a uniform pricing constraint for cash and debit card...

Using a standard Ramsey approach, we examine an optimal allocation of the social cost for electronic payment system in the context of a dynamic general equilibrium model where money is essential. The benevolent government provides electronic payment services and allocates the relevant social...

The welfare cost of inflation is explored via a search-theoretic model in which along with non-interest-bearing cash, interest-bearing liquid and illiquid assets are available. With inflation, agents are willing to replace higher-return illiquid assets with lower return liquid assets for...

The welfare cost of inflation is studied with a model in which non-interest-bearing money coexists with an interest-bearing liquid asset. Compared to a money-only model, the presence of an interest-bearing liquid asset reduces the consumption distortion of inflation. However, it also induces the...

A simple monetary model is constructed to study the implications of an indexed unit of account (Indexed-UoA). In an economy with an Indexed-UoA, credit trade friction attributed to inflation is resolved and there is no redistributional effect from unexpected inflation between debtors and...

Retailers in the Netherlands and the U.K. can charge different prices for a commodity depending on whether cash or a debit card is used as payment, whereas retailers in the U.S. generally cannot. These two types of economies with and without a uniform pricing constraint for cash and debit card...

The coexistence puzzle is explained via an interaction between intermediary cost and uncertainty with regards to consumption trade. If a trade opportunity as a buyer is more likely to arise, ex-ante net return on bond at the margin would be negative up to a certain amount of transactions and,...
