Using a portfolio balance model of exchange rate determination, this paper develops a theoretical explanation of why central banks do not make precise announcements of their exchange rate targets. In foreign exchange markets, where it is common knowledge that the central bank intervenes to...

A finite number of sellers (n) compete in schedules to supply an elastic demand. The costs of the sellers have uncertain common and private value components and there is no exogenous noise in the system. A Bayesian supply function equilibrium is characterized; the equilibrium is privately...

Deposit insurance schemes are becoming increasingly popular around the world and yet there is little understanding of how they should be designed and what their consequences are. In this Paper we provide a new rationale for the provision of deposit insurance. We analyse a model in which agents...

A model is presented of a uniform price auction where bidders compete in demand schedules; the model allows for common and private values in the absence of exogenous noise. It is shown how private information yields more market power than the levels seen with full information. Results obtained...

We study interventions to restore efficient lending and investment when financial markets fail because of adverse selection. We solve a design problem where the decision to participate in a program offered by the government can be a signal for private information. We charac terize optimal...

We analyse a general equilibrium model in which there is both adverse selection of and moral hazard by banks. The regulator has several tools at their disposal to combat these problems. They can audit banks to learn their type prior to giving them a license, they can audit them ex post to learn...

I consider some of the leading arguments for assigning an important role to tracking the growth of monetary aggregates when making decisions about monetary policy. First, I consider whether ignoring money means returning to the conceptual framework that allowed the high inflation of the 1970s....

In a simple macromodel with forward-looking expectations, this Paper looks into disclosure policy when a central bank has private information on future shocks. The main result is that advance disclosure of forecasts of future shocks does not improve welfare, and in some cases is not desirable as...

The paper discusses several issues related to how monetary policy should be conducted in an era of price stability. Low inflation (with base drift in the price level) and price-level stability (without such base drift) are compared, and a suitable loss function (corresponding to flexible...

We construct a model to analyse the two types of tender procedures used by the European Central Bank (ECB) in its open market operations. We assume that the ECB minimizes the expected value of a loss function that depends on the quadratic difference between the interbank rate and a target...
