Abstract In this paper I explore the quantitative implications for savings of population aging. In doing so, I pay particular attention to some features that have been partially over-looked in the literature. These features include the details of the population aging process, the initial...

Abstract This paper explores the efficiency of decentralized search behavior and matching patterns in a model with ex ante heterogeneity and a constant returns to scale search technology. We show that a linear tax or subsidy on search intensity decentralizes the social optimum. In the absence of...

Abstract We develop a two-country, two-currency, search-theoretic model of monetary exchange, extending previous such models by endogenizing prices using bargaining theory. We analyze features of the environment that make it more likely that a given money circulates internationally. We show the...

This paper shows that, in a multi-country framework with government deficit spillovers, designing institutions that reduce the budget deficit is an optimal response from a country's individual point of view. However, at an aggregate level this non-cooperative behavior is counterproductive. The...

We compare equilibrium allocations in directed search models where prices are determined alternatively by posting and by competing auctions, with the following results. With finite numbers of players, sellers' expected payoffs are higher when all sellers auction than when all sellers post. This...

A common hypothesis of interest in estimated Taylor rules is whether the Federal Funds rate increases more than one-for-one with inflation; a rule with this characteristic is described as stabilizing. This paper discusses the interaction of this hypothesis with the widespread use of a partial...
