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,...

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...

Evidence supports the notion that those who grow up to be patient dobetter than those who do not. Parents can inculcate the virtue of delayedgratiÂ…cation in their children by taking the right actions. We study a modelin which parents, for selÂ…sh reasons, invest resources to raise patient...

This paper shows how policies aimed at insuring health risks and those intended to improve the environment are (and should be) deeply intertwined. In the model economy, inspired by recent Chinese experience, pollution raises the likelihood of poor health in the future prompting agents to self...
