In monetary models in which agents are subject to trading shocks there is typically an ex-post inefficiency in that some agents are holding idle balances while others are cash constrained. This inefficiency creates a role for financial intermediaries, such as banks, who accept nominal deposits...

This paper advances three fundamental propositions regarding money: (1) As R. W. Clower (1965) famously put it, money buys goods and goods buy money, but goods do not buy goods. (2) Money is always debt; it cannot be a commodity from the first proposition because, if it were, that would mean...

This paper presents an integrated theory of money and banking. I address the following question: when both individuals and banks have private information, what is the optimal way to settle debts? I develop a dynamic model with micro-founded roles for banks and a medium of exchange. I establish...

While the mainstream long argued that the central bank could use quantitative constraints as a means to controlling the private creation of money, most economists now recognize that the central bank can only set the overnight interest ratewhich has only an indirect impact on the quantity of...

The sharp exchanges that Keynes had with some of his critics on the loanable funds theory made it harder to appreciate the degree to which his thought was continuous with the tradition of monetary analysis that emanates from Wicksell, of which Keynes's A Treatise on Money was a part. In the...

We establish a benchmark result for the relationship between the loanablefunds and the money-creation approach to banking. In particular, we show that both processes yield the same allocations when there is no uncertainty and thus no bank default. In such cases, using the much simpler...

Irving Fisher's encounter with the Quantity theory of Money began in the 1890s, during the debate about bimetallism, and reached its high point in 1911 with the publication of The Purchasing Power of Money. His most important refinement of the theory, derived from his recognition of bank...

We present a thought-provoking study of two monetary models: the cash-in-advance and the Lagos and Wright (2005) models. We report that the different approach to modeling money - reduced-form vs. explicit role - neither induces theoretical nor quantitative differences in results. Given...

Monetary theorists have advanced an intriguing notion: we exchange money to make up for a lack of enforcement, when it is difficult to monitor and sanction opportunistic behaviors. We demonstrate that, in fact, monetary equilibrium cannot generally be sustained when monitoring and punishment...

This paper uses the occasion of the twenty-fifth anniversary of Basil Moore's book, Horizontalists and Verticalists, to reassess the theory of endogenous money. The paper distinguishes between horizontalists, verticalists, and structuralists. It argues Moore's horizontalist representation of...
