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...

In this paper, we study a decentralized monetary economy with a specified set of markets, rules of trade, an equilibrium concept, and a restricted set of policies and derive a set of equilibrium (monetary) allocations. Next we set up a simpler constrained planning problem in which we restrict...

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

This paper clarifies and extends previous work on the equivalence between monetary regimes and fiscal regimes involving social security systems. We show that monetary regimes of the type we study are equivalent to two alternative types of social security regimes. This result has two important...

Researchers have incorporated labor or credit market frictions in isolation within simple neoclassical models to open up a role for institutions, inject realism into their models and examine the impact of these distortions on output and employment. We present an overlapping generations model...

We study the properties of two-period monetary cycles in simple pure exchange overlapping generations economies in which the households live for three periods. We demonstrate that these economies can support cycles under a much broader -- and, arguably, more plausible -- range of assumptions...

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

We consider an otherwise conventional monetary growth model in which spatial separation and limited communication create a transactions role for currency, and stochastic relocation gives rise to financial intermediaries. In this framework we consider how changes in fiscal and monetary policy,...

A classic result in dynamic public economics states that there is no welfare rationale for pay-as-you-go (PAYG) pensions in a dynamically-efficient neoclassical economy with exogenous labor supply. Parenthetically, a welfare justification for PAYG pensions exists if the economy is dynamically...

In most demographic transitions, declines in child mortality precede declines in net fertility rates. Variants of the Barro-Becker model of fertility fail to deliver this link. A simple extension, the inclusion of social norms regarding fertility, generates the desired effect.
