There is a growing interest in multi-sector models that combine aggregate balanced growth, consistent with the well-known Kaldor facts, with systematic changes in the relative importance of each sector, consistent with the Kuznets facts. Although variations in the income elasticity of demand...

Constructing a dynamic game model of trade of an exhaustible resource, this paper compares feedback Nash and Stackelberg equilibria when the exporting country sets quantity rather than price. We consider two different leadership scenarios: leadership by the importing country, and leadership by...

The purpose of this study is to illustrate, using a simple model of monopolistic competition with multi-product firms, how trade liberalization affects the degree of foreign brand penetration. We model this in terms of the profit incentives for domestic entrepreneurs to choose to offer domestic...

In a model where a monopolistic downstream firm (assembler) negotiates simultaneously with each of its intermediate-input suppliers the prices of the complementary components which enter its product, we analyze the process by which the assembler separates from its suppliers as a Markov Perfect...

Does a country strictly gain if it acts as a leader in a resource market under bilateral monopoly? Using differential games, we show that the answer is "yes"" when leadership can be exercised globally (global Stackelberg leadership), but possibly ""no"" when it is exercised only at each stage...

This paper examines how two geographically separated ports compete for a market consisting of manufacturing firms located between the two ports. There is a firm in each port, and these two firms, taking the infrastructure provided by their governments as given, compete in a Bertrand sense. The...

This paper proposes a new welfare criterion which satisfies three desiderata: strong sensitivity to the least advantaged, sensitivity to the present, and sensitivity to the future. We develop necessary conditions for optimal paths under this new criterion, and demonstrate that, in a familiar...

A model of location choice by Cournot oligopolists is presented, under the assumption that R&D spillovers depend on the distance between firms. We show that a variety of patterns emerge. Agglomeration is optimal under certain assumptions. Geographical dispersion in a two-dimensional plane is...

We present a model where the probability distribution over the space of an agent's achievements depends not only on her ability and effort, but also on the goals set for her. The agent chooses her effort according to her utility net of perceived cost of effort. This cost is inversely...

In this paper, we consider an asymmetric polluting oligopoly: firms have different production costs, and their pollution characteristics may also be different. We will demonstrate that, in this case, optimal tax rates per unit of emission are not the same for all firms. We call this property...
