This paper develops a two-sector overlapping generations model in which one sector produces an externality on the environmental quality and the other has no effect. We assume that environmental quality degradation results from production activity of one sector. Then, we characterize the...

Kimball [1990] developps a theory of prudence isomorphic to Pratt [1964] and Arrow [1965] theory of risk aversion. Nevertheless, if the Arrow-Pratt risk aversion index determines behavior in risk, it is not always the case for prudence. Moreover, concept of prudence and precautionary behavior...

Models of tax competition usually assume a single period framework. This paper sets up a repeated interactions model of tax competition, and establishes conditions under which fiscal policy harmonization can result from repeated interactions between governments. It is shown that fiscal policy...

In this paper, we study the intertemporal equilibria of an infinite-lived representative agent model with public debt. We show that for a given path of government expenditures, there generally exist a continuum of equilibria depending on various debt policies.

This paper is a study of money in overlapping generations models with cash-in-advance constraints a la Champ and Freeman and Hahn and Solow. We first offer a brief review of different features of the cash-in-advance constraint. Then we propose a general formulation. We show that neutrality of...
