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...

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...

We derive emission tax rules that take into account (i) the rent-shifting argument, (ii) the need to mitigate transboundary pollution, (iii) correction for restrictive oligopoly output, and (iv) correction for domestic coordination of outputs. We show that trade liberalization does not...

We analyze a model of lobbying by oligopolists who allocate resources between lobbying and internal cost-reducing activities. We ask the following questions: (i) if firms differ with respect to comparative advantage in lobbying, what is the equilibrium allocation of resources between lobbying...

Favoritism in vertical relationship is a situation in which an upstream firm sets favorable exchange conditions to some agents at the expense of others. This paper explores the reason for, and direction of, favoritism in the vertical relationship between an upstream firm and a number of...
