Monetary Policy Implementation with an Ample Supply of Reserves
Methods of monetary policy implementation continue to change. The level of reserve supply—scarce, abundant, or somewhere in between—has implications for the efficiency and effectiveness of an implementation regime. The money market events of September 2019 highlight the need for an analytical framework to better understand implementation regimes. We discuss major issues relevant to the choice of an implementation regime, using a parsimonious framework and drawing from the experience in the United States since the 2007–09 financial crisis. We find that the optimal level of reserve supply ...

Nearsighted justice
Chapter 11 structures complex negotiations between creditors and debtors that are overseen by a bankruptcy court. This paper identifies conditions under which it is optimal for the court to sometimes err in determining whether a firm should be liquidated. Such errors can affect the optimal action choices by both good and bad entrepreneurs. We first characterize the optimal error rate without renegotiation, providing conditions under which it is optimal for the court both to sometimes mistakenly liquidate "good firms," but not "bad firms." When creditors and debtors can renegotiate to ...

Some benefits of cyclical monetary policy
In this paper, we present a simple random-matching model in which different seasons translate into different propensities to consume and produce. We find that the cyclical creation and destruction of money is beneficial for welfare under a wide variety of circumstances. Our model of seasons can be interpreted as providing support for the creation of the Federal Reserve System, with its mandate of supplying an elastic currency for the nation.

Introduction to the macroeconomic dynamics: special issues on money, credit, and liquidity
We motivate and provide an overview to New Monetarist Economics. We then briefly describe the individual contributions to the Macroeconomics Dynamics special issues on money, credit and liquidity.

The tale of Gresham's law
Gresham?s law, which says that bad money tends to drive good money out of circulation, may account for many nations? episodes of money troubles, as far back as ancient Athens. This Commentary discusses the two main explanations for Gresham?s law and suggests some circumstances in which the law does not apply.

Limited liability and the development of capital markets
We study the consequences of the introduction of widespread limited liability for corporations. In the traditional view, limited liability reduces transactions costs and enhances investment incentives for individuals and firms. But this view does not explain several important stylized facts of the British experience, including the slow rate of adoption of limited liability by firms in the years following legal reforms. We construct an alternative model that accounts for this and other features of the nineteenth century British experience. In the model, project risk is private information, and ...

On the recognizability of money
This paper develops a model of currency circulation under asymmetric information. Agents are heterogeneous and trade in bilateral matches. Coins are intrinsically valuable and are available in two weights, light and heavy. We characterize the equilibrium under complete information and under imperfect information about the quality of coins. We determine a set of conditions under which the two currencies circulate and are traded according to different terms of trade. We study how output, welfare, and the velocity of currency are affected by the recognizability of coins. We show that society's ...

Bank runs without sequential service
Banking models in the tradition of Diamond and Dybvig (1983) rely on sequential service to explain belief driven runs. But the run-like phenomena witnessed during the financial crisis of 2007-08 occurred in the wholesale shadow banking sector where sequential service is largely absent. This suggests that something other than sequential service is needed to help explain runs. We show that in the absence of sequential service runs can easily occur whenever bank-funded investments are subject to increasing returns to scale consistent with available evidence. Our framework is used to understand ...

Diamond-Dybvig and Beyond: On the Instability of Banking
Are financial intermediaries—in particular, banks—inherently unstable or fragile, and if so, why? We address this question theoretically by analyzing whether model economies with financial intermediation are more prone than those without it to multiple, cyclic, or stochastic equilibria. We consider several formalizations: insurance-based banking, models with reputational considerations, those with fixed costs and delegated investment, and those where bank liabilities serve as payment instruments. Importantly for the issue at hand, in each case banking arrangements arise endogenously. ...
