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...

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...

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...

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...

The authors investigate the extent to which monetary policy can enhance the functioning of the private credit system. Specifically, they characterize the optimal return on money in the presence of credit arrangements. There is a dual role for credit: It allows buyers to trade without fiat money...

When agents are liquidity constrained, two options exist - sell assets or borrow. We compare the allocations arising in two economies: In one, agents can sell government bonds (outside bonds) and in the other they can borrow (issue inside bonds). All transactions are voluntary, implying no...

We study the effects of money (anticipated inflation) on capital formation. Previous papers on this adopt reduced-form approaches, putting money in the utility function or imposing cash in advance, but use otherwise frictionless models. We follow a literature that is more explicit about the...

David Hume's monetary theory has two standard yet inconsistent readings. As a forefather of the quantity theory of money, Hume sees money as neutral. As an inflationist, Hume sees an active positive role for monetary policy. This paper reads Hume consistently instead, by showing that for Hume...

We describe counterfeiting activity as the issuance of private money, one which is difficult to monitor. Our approach, which amends the basic random-matching model of money in mechanism design, allows a tractable welfare analysis of currency competition. We show that it is not efficient to...

When agents are liquidity constrained, two options exist - borrow or sell assets. We compare the welfare properties of these options in two economies: in one, agents can borrow (issue inside bonds) and in the other they can sell government bonds (outside bonds). All transactions are voluntary,...
