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,...

TTwo equilibrium possibilities are known to obtain in a standard overlapping-generations model with dynastic preferences: either the altruistic bequest motive is operative for every generation (in which case, Ricardian equivalence obtains) or it is not, for any generation. Dynamic equilibria,...

This paper studies a pure-exchange monetary overlapping generations economy in which young and old agents face exogenous minimum consumption requirements, and money is the only asset. The presence of the minimum consumption requirement on the old is shown to produce multiperiodic monetary...

This note studies a model in which heterogeneous income agents get a utility boost only when their consumption catches up with the Joneses'. The resulting utility function is non-concave. In this setup, participation in a fair consumption lottery has the potential to make some agents ex-ante...

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.

In this paper, we assume away standard distributional and static-efficiency arguments for public health, and instead, seek a dynamic efficiency rationale. We study a lifecycle model wherein young agents make health investments to reduce mortality risk. We identify a welfare rationale for public...

We compare two institutions head on, a family compact – a parent makes a transfer to her parent in anticipation of a possible future gift from her children – with a pay-as-you-go, social security system in a lifecycle model with endogenous fertility wherein children are valued both...
