We study a decentralized trading model as in Peters (1984), where a finite number of heterogeneous capacity-constrained sellers compete for a finite number of homogeneous buyers, by posting prices. This "directed search" model is known to admit symmetric equilibria; yet, uniqueness has proved...

The literature on excess entry shows that the free-entry equilibrium number of firms may be greater than is socially optimal and proposes government entry regulation as a remedy. This article tries to show that such a policy recommendation is misleading. A two-period, three-person entry game...

We develop a microfounded model, where agents have the possibility to trade money for government bonds in an over-the-counter market. It allows us to address important open questions about the effects of central bank purchases of government bonds, these being: under what conditions these...

In the post-crisis period, increased regulation of financial intermediaries led to a significant decline in corporate bond market liquidity. In order to stabilize these markets, policy makers recently proposed that the trading of corporate bonds should be more centralized. In this paper, we show...

We develop a dynamic general equilibrium model to analyze the effects of central bank purchases of government bonds by investigating the following three questions: Under what conditions are these purchases socially desirable, what incentive problems do they mitigate, and how large are these...

We integrate an overlapping generations model into a new monetarist framework and show that the Friedman rule is not optimal. This is because inflation makes saving for retirement less attractive, such that young agents optimally choose to increase their consumption at the expense of lower...

We develop a dynamic general equilibrium model to analyze the relationship between monetary policy, money demand, and unemployment. Our model succeeds in replicating the empirical fact of a downward sloping Phillips curve for low inflation rates and an upward sloping curve for high inflation...

Shortages in organs for transplantation have resulted in a renewed interest in designing incentive policies to promote organ supply. The donor-priority rule, which grants priority for transplantation based on deceased organ donor registration status, has proven to be effective in both theory and...
