The Friedman rule, a widely studied prescription for monetary policy, is optimal in Townsend's turnpike model of money; it is not so in the overlapping generations version of his stochastic relocation model of money. We investigate these monetary models in the light of this disparity. To that...

In this paper, we explore the connection between optimal monetary policy and heterogeneity among agents. We study a standard monetary economy with two types of agents in which the stationary distribution of money holdings is non-degenerate. Sans type-specific fiscal policy, we show that the...

In this paper, we argue that the observed difference in the cost of intraday and overnight liquidity is part of an optimal payments system design. In our environment, overnight liquidity affects output while intraday liquidity affects only the distribution of resources between money holders and...

This paper studies a overlapping generations economy with capital where limited communication and stochastic relocation create an endogenous transactions role for fiat money. We assume a production function with a knowledge-externality (Romer-style) that nests economies with endogenous growth...

Recent theoretical work shows that changes in the volatility of inflation and/or unemployment affect equilibrium inflation outcomes when the central banker's loss function is asymmetric. We show that previous evidence offered in support of the proposition that the volatility of unemployment...

Caplin and Leahy (1996) show that, when central bankers learn about the economy by observing its response to policy shock, cautious monetary policy may be ineffectual as private agents correctly anticipate that today's interest rate cuts are likely to be followed by future cuts. The central...

We study several popular monetary models which generate a non-degenerate stationary distribution of money holdings. Across these environments, our principal finding is as follows: a monetary policy that sets long run nominal interest rates to zero (the Friedman rule) does not typically maximize...

Inflation rates in a number of OECD follow a common trend over the past four decades: inflation starts out low in the 1960s, rises for a time before peaking in the 1970s or early 1980s, and then falls back to initial levels. This similarity in the behavior of trend inflation suggests that any...
