Search, money, and inflation under private information

I study a version of the Lagos-Wright (2003) model of monetary exchange in which buyers have private information about their tastes and sellers make take-it-or-leave-it-offers (i.e., have the power to set prices and quantities). The introduction of imperfect information makes the existence of monetary equilibrium a more robust feature of the environment. In general, the model has a monetary steady state in which only a proportion of the agents hold money. Agents who do not hold money cannot participate in trade in the decentralized market. The proportion of agents holding money is endogenous and depends (negatively) on the level of expected inflation. As in Lagos and Wright's model, in equilibrium there is a positive welfare cost of expected inflation, but the origins of this cost are very different.Money - Mathematical models

Government Policy and the Probability of Coordination Failures

This paper introduces an approach to the study of optimal government policy in economies characterized by a coordination problem and multiple equilibria. Such models are often criticized as not being useful for policy analysis because they fail to assign a unique prediction to each possible policy choice. We employ a selection mechanism that assigns, ex ante, a probability to each equilibrium indicating how likely it is to obtain. We show how such a mechanism can be derived as the natural result of an adaptive learning process. This approach leads to a well-defined optimal policy problem, and has important implications for the conduct of government policy. We illustrate these implications using a simple model of technology adoption under network externalities.

Understanding monetary policy implementation

The Federal Reserve implements its monetary policy objectives by intervening in the interbank market for overnight loans. In particular, it aims to change the supply of reserves available to commercial banks so that the (average) interest rate in this market equals an announced target rate. A recent change in legislation will give the Federal Reserve greater flexibility in this process by allowing it to pay interest on reserve balances. Together, the change and recent events in financial markets have renewed interest in the process of monetary policy implementation. This article presents a simple analytical framework for understanding this process. We use the framework to illustrate the main factors that influence a central bank’s ability to keep the market interest rate close to a target level. We also discuss how paying interest on reserves can be a useful policy tool in this regard.Monetary policy ; Federal Reserve banks
