We construct a model of consumer credit with payment frictions, such as spatial separation and unsynchronized trading patterns, to study optimal monetary policy across different interbank market structures. In our framework, intermediaries play an essential role in the functioning of the payment...

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...

The authors study optimal monetary policy in a model in which fiat money and private debt coexist as a means of payment. The credit system is endogenous and allows buyers to relax their cash constraints. However, it is costly for agents to publicly report their trades, which is necessary for the...

The author studies the terms of credit in a competitive market in which sellers (lenders) are willing to repeatedly finance the purchases of buyers (borrowers) by engaging in a credit relationship. The key frictions are: (i) the lender is unable to observe the borrower's ability to repay a loan;...

We show the existence of an inherent instability associated with a purely private monetary system due to the role of endogenous debt limits in the creation of private money. Because the bankers' ability to issue liabilities that circulate as a medium of exchange depends on beliefs about future...

We show that the regulation of bank lending practices is necessary for the optimal provision of private liquidity. In an environment in which bankers cannot commit to repay their creditors, we show that neither an unregulated banking system nor narrow banking can provide the socially efficient...

It has been largely acknowledged that monetary policy can affect borrowers and lenders differently. This paper investigates whether the distributional effects of monetary policy are an inherent feature of monetary economies with private credit instruments. In our framework, both money and credit...

Monetary economists have long recognized a tension between the benefits of fractional reserve banking, such as the ability to undertake more profitable (long-term) investment opportunities, and the difficulties associated with fractional reserve banking, such as the risk of insolvency for each...

The goal of this paper is to provide a framework to analyze the effectiveness of bank coalition formation in response to an external aggregate shock that may cause disruption to the payment mechanism and real economic activity. I show that the kind of insurance mechanism provided by a specific...

This paper develops a dynamic model of bank liquidity provision to characterize the ex post efficient policy response to a banking panic and study its implications for the behavior of output in the aftermath of a panic. It is shown that the trajectory of real output following a panic episode...
