We develop a 2-country model of legal dynamics in which each country's social welfare depends generally on its actual law, its culturally ideal one, its technologically efficient one and the actual law of the other country. In our model, countries are better off when all these laws coincide....

The purpose of this note is to study first a notion of a surplus function that originates in the work of [Boiteux, M., 1951. Le Revenu Distribuable et les Pertes Économiques. Econometrica 112-133] and to rely upon this notion to study dual Pareto efficiency in an exchange economy. This...

Private property in land has often been criticized because it is supposed to bring about a waste of productive resources weakening economic growth. Indeed, because it is non reproductible, land earns a rent which increases in a growing economy and whose capitalization decreases the "productive"...

This paper investigates the macroeconomic portfolio implications of monopoly rents. We make use of a two-sectors overlapping generations model with a Cournot oligopoly in one sector. We show that when the competitive equilibrium is characterized by under-capitalization with respect to the golden...

This note shows that a general oligopolistic equilibrium (GOLE), a notionrecently introduced in the literature by Neary, may be Pareto-efficient. Consequently,at a GOLE, the allocation of resources can be identical to thatof a competitive equilibrium. We also propose a characterization of...

This article is devoted to a study of the optimal monetary and fiscal policies within the framework of an overlapping generations model with cash-in-advance constraints. We first characterize the intertemporal equilibrium. Then we show how to decentralize the optimal growth path using available...

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 exists a continuum of equilibria depending on various debt policies. These equilibria are characterized...
