A number of recent papers reach different conclusions concerning the effects of trade and industrial policy on imperfectly competitive industries; the implications for policy are therefore sensitive to assumptions concerning both firm behaviour and market structure. This paper sets out a single...

An important component of Robert Lipsey's work has been his research on multinational firms, and his careful documentation of their behavior in terms of production and intra-firm trade. In this paper, we extend recent theory referred to as the knowledge-capital model', which simultaneously...

A two-sector, two-period trade model is developed in which one sector has increasing returns based on the creation of specialized intermediate inputs. One of the two (otherwise identical) countries is not able to enter the increasing returns sector in the first period through some "accident of...

Almost all of the large literature on international trade with imperfect competition assumes exogenous market structures. The purpose of this paper is to develop a simple model that generates alternative market structures as Nash equilibria for different parameterizations of the basic model....

We illuminate the relationship between optimal firm pricing and optimal trade policy by exploring a generalized model that accommodates product differentiation at both the national and sub-national (firm) levels. We assume monopolistic competition in the differentiated products at the...

At some conceptual level, trade in goods and services are not that much different. However, the speed at which trade and foreign investment in services is growing, along with the fact that the barriers to these activities are quite different from those for trade in goods, prompts us to take a...

A poorly understood empirical phenomenon is export-platform affiliate production (EP), particularly for sale in third countries rather than in the parent or host countries. We develop a three-region model, with two identical large, high-cost countries (collectively called North) and a small,...
