Much of Africa has been ravaged by the AIDS epidemic. There, heterosexual contact is the primary mode of transmission for the HIV virus. Even when access to condoms is good and their price low, a large fraction of young Africans continue to engage in unprotected sex. In this paper, we propose a...

Central banks typically find it difficult to turn off the "political pressure valve". This has important consequences for the types of monetary policies they implement. This paper presents an analysis of how political factors may come into play in the equilibrium determination of inflation. We...

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...

We study a variant of the conventional keeping-up-with-the-Joneses setup in which heterogeneous-ability agents care both about consumption and leisure and receive an utility premium if their consumption exceeds that of the Joneses'. Unlike the conventional setup in which all agents are assumed...

In an overlapping generations model, momentary equilibria are defined as points that lieon the intergenerational offer curve, i.e., they satisfy agents’ optimality conditions and marketclearing at any date. However, some dynamic sequences commencing from such points may notbe considered valid...

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...

This paper takes a discrete-time adaptation of the continuous−time matching economy described in Pissarides (1990, 2000), and computes the solution to the dynamic planning problem. The solution is shown to be completely characterized by a first−order, non−linear map. We show that the map...
