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...
