"High-powered money has been declining relative to nominal GDP in the United States. Does the ability of monetary policy to affect aggregate activity decline as the money-income ratio falls? In this paper, I specify simple model economy, examining the effects that monetary policy actions and...

In this paper, we argue that the observed di¤erence in the cost of intraday and overnightliquidity is part of an optimal payments system design. In our environment, the interestcharged on overnight liquidity a¤ects output while the cost of intraday liquidity onlyaffects the distribution of...

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

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

In models of money with an infinitely-lived representative agent (ILRA models), the optimal monetary policyis almost always the Friedman rule. Overlapping generations (OG) models are different: in this paper, westudy how they are different, and why. We investigate the welfare properties of...

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...

Central banks typically find it difficult to turn off the "political pressure valve". This has important consequences for the types of monetary policies they implement. This paper presents an analysis of how political factors may come into play in the equilibrium determination of inflation. We...
