We develop a model in which the heterogeneous firms in an industry choose their modes of organization and the location of their subsidiaries or suppliers. We assume that the principals of a firm are constrained in the nature of the contracts they can write with suppliers or employees. Our main...

We propose a new solution concept for a game among oligopolists that simultaneously compete in several segmented markets. The motivation for this solution comes from international trade, but it also has applications in other areas. It is based on a three-stage extension of the two-stage...

Empirical studies have found that enhanced foreign competition can encourage or discourage innovation. To address this relationship, I examine a market structure in which a small number of large multi-product oligopolists compete with a large number of small single-product firms in the same...

We develop a model of large multinational enterprises, each one producing a continuum of products. These outsized firms compete as oligopolists in a domestic and foreign market, facing competitive pressure from single-product firms that engage in monopolistic competition. The multinational...

Polities differ in the extent to which political parties can pre-commit to carry out promised policy actions if they take power. Commitment problems may arise due to a divergence between the ex ante incentives facing national parties that seek to capture control of the legislature and the ex...

We examine the effects of the interaction between lobbying and legislative bargaining on policy formation. Two systems are considered: a US-style congressional system and a European-style parliamentary system. First, we show that the policies generated are not intermediate between policies that...

We study the competition between two political parties for seats in a parliament. The parliament will set two types of policies: ideological and non-ideological. The parties have fixed positions on the ideological issues, but choose their non-ideological platforms to attract voters and campaign...

This paper explores a series of general-equilibrium models in which people can choose to be either producers or predators, and in which producers can allocate their resources either to production or to guarding their production against predators. The analysis shows how the ratio of predators to...

We consider a model in which the level of taxes and seignorage are too low to finance government expenditures and debt service. Government debt will therefore grow without bound, implying the eventual need to change policy. Starting with utility maximization, we analyze the effect of the...
