In this article, I discuss the broad influence of Diamond and Dybvig (1983) in the field of money and banking. My review is centered on two aspects of their sharp concept of liquidity when doing mechanism design in a simple economy with a single resource constraint. It calls into question an old...

This special issue of the Economic Quarterly is dedicated to the 1983 model of bank runs developed by Douglas Diamond and Philip Dybvig. Their model has been a workhorse of banking research over the last 25 years and during the recent financial crisis it has been one that researchers and...

Recent models of monetary policy can have indeterminacy of equilibria. The indeterminacy property is often viewed as a difficulty of these models. We consider its significance using the learning approach to expectations formation by employing expectational stability as a robustness criterion for...

Following the New Classical Macroeconomics and the New Keynesian Macroeconomics, the independence of central banks significantly increased after 1990, which could preclude the coordination between the fiscal and the monetary policies. The purpose of this paper is to consider the stabilizing...
