Rejuveniles are "grown-ups who cultivate juvenile tastes in products and entertain-ment". In this note, we study a standard AK growth model of overlapping gener-ations populated by rejuveniles. For our purposes, rejuveniles are old agents whoderive utility from "keeping up" their consumption...

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...

This paper introduces endogenous longevity risk in an otherwisestandard overlapping generations model with capital. In the model, an agent mayincrease the length of her old age by incurring investments in her own health fundedfrom her wage income. Such private health investments are more...

Faced with real and nominal shocks, what should a benevolent central bankdo, …x the money growth rate or target the inflation rate? In this paper, wemake a …rst attempt at studying the optimal choice of monetary policy in-struments in a micro-founded model of money. Speci…cally, we produce...

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

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...

This paper represents a first attempt at a tractable analysis of how monetary policy influences the income distribution in an economy. It presents a monetary growth model in which inflation affects credit market efficiency, and via this link, influences capital accumulation, and the income...

Many countries around the world have large public pension programs. Traditionally, these programshave been used to induce retirement by the elderly in order to free up jobs for the young andto redistribute income across generations. This paper provides an efficiency rationale for the...
