We study discretionary equilibrium in the Calvo pricing model for a monetary authority that chooses the money supply. The steady-state inflation rate is above 8 percent for a baseline calibration, but it varies substantially with alternative structural parameter values. If the initial condition...

This paper develops a general equilibrium model in which households face fixed costs associated with searching for a new supplier of consumption goods. These search costs provide firms with some monopoly power over their existing customers and generate the kind of customer flow dynamics first...

We describe a stochastic economic environment in which the mix of money and trade credit used as means of payment is endogenous. The economy has an infinite horizon, spatial separation and a credit-related transaction cost, but no capital. We find that the equilibrium prices of arbitrary...

Optimal monetary policy maximizes welfare, given frictions in the economic environment. Constructing a model with two sets of frictions - the Keynesian friction of costly price adjustment by imperfectly competitive firms and the Monetarist friction of costly exchange of wealth for goods - we...

Reasoning within the New Neoclassical Synthesis (NNS) we previously recommended that price stability should be the primary objective of monetary policy. We called this a neutral policy because it keeps output at its potential, defined as the outcome of an imperfectly competitive real business...

In a canonical staggered pricing model, monetary discretion leads to multiple private sector equilibria. The basis for multiplicity is a form of policy complementarity. Specifically, prices set in the current period embed expectations about future policy, and actual future policy responds to...

The paper explores the relationship between financial stability, deflation, and monetary policy. A discussion of narrow liquidity, broad liquidity, market liquidity, and financial distress provides the foundation for the analysis. There are two preliminary conclusions. Equity prices are a...

For the United States economy (1960-1989), the correlation between the growth rates of the Solow residual and the real price of energy (government spending) is -0.55 (0.09). The Solow residual confounds movements in energy prices and government spending with those in true technology. Why? To...

Arguments in favor of Keynesian models as opposed to real business cycle models are often made on the grounds that the correlations and impulse response patterns found in the latter are inconsistent with the data. A recent and prominent example of this reasoning is Gali (1999). But certain...

Various laws and policy proposals call for regulators to make use of the information reflected in market prices. We focus on a leading example of such a proposal, namely that bank supervision should make use of the market prices of traded bank securities. We study the theoretical underpinnings...
