This paper explores a series of general-equilibrium models in which people can choose to be either producers or predators, and in which producers can allocate their resources either to production or to guarding their production against predators. The analysis shows how the ratio of predators to...

This paper examines the international experiences with four basic types of monetary policy regimes: 1) exchange-rate targeting, 2) monetary targeting, 3) inflation targeting, and 4) monetary policy with an implicit but not an explicit nominal anchor. The basic theme that emerges from this...

This paper reports empirical tests for the existence of rational bubbles in stock prices. The analysis focuses on a familiar model that defines market fundamentals to be the expected present value of dividends, discounted at a constantrate, and defines a rational bubble to be a self-confirming...

A rational bubble would involve a self-confirming belief that an asset price depends on information that includes variables or parameters that are not part of market fundamentals. The existing literature shows that, if market fundamentals are economically interesting, i.e., forward looking, any...

This paper derives a reputational equilibrum for inflation in a model in which the government obtains valuable seigniorage by issuing fiat money in echange for real resources. One insightful result is that , with contemporaneous perceptionof actual government behavior and immediate adjustment of...

This paper attempts to provide a perspective on the causes of inflation by exploring why sustained inflations occur and the role of monetary policy in the inflation process. The conclusion reached in this paper is that in the last ten years there has been a convergence of views in the economics...

This paper focuses on the problem of formulating an analysis of economic policy that is consistent with rational expectations. Cooley, LeRoy,and Raymon show that the Lucas and Sargent strategy for econometric policy evaluation is itself vulnerable to the logic of the Lucas critique. The present...

Several recent studies find that ex ante real returns for short-term U.S. Treasury securities are negatively correlated both with inflation and with nominal interest rates. This paper examines whether these findings extend to the short-term holding return on publicly and privately issued...
