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...

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,...

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 rate - which has only an indirect impact on the quantity of...

How well can a cryptocurrency serve as a means of payment? We study the optimal design of cryptocurrencies and assess quantitatively how well such currencies can support bilateral trade. The challenge for cryptocurrencies is to overcome double-spending by relying on competition to update the...

In this paper, we focus on the Lagos and Wright (2005) monetary search model - a workhorse in the so-called New Monetarist Economics. After describing this micro-founded yet tractable framework, we review recent developments in extending it to study a variety of issues from monetary theory to...

This paper studies the efficiency of electronic money system by focusing on the decentralized setting of issuance. In the model competitive money issuers can create small denominated money (or e-money) backed by large denominated government bonds. Under the decentralized environment the issuers...

Monetary theory texts teach that governments create money and control monetary policy. Researchers at the Bank of England, IMF and many others show that fractional reserve banking allows the private sector to create money. Most money currently in existence is created by the private sector,...
