"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 difference in the cost of intraday and overnight liquidity is part of an optimal payments system design. In our environment, the interest charged on overnight liquidity affects output, while the cost of intraday liquidity only affects the distribution of...

We examine models with spatial separation and limited communication that have shown some promise toward resolving the disparity between theory and practice concerning optimal monetary policy; these models suggest that the Friedman rule may not be optimal. We show that intergenerational transfers...

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...
