We formulate a two-country model with monopolistic competition and heterogeneous firms to reconsider labor market linkages in open economies. Labor-market imperfections arise by virtue of country-specific real minimum wages. Two principal experiments are considered. First, we show that trade...

This paper argues that the theoretical foundations for the gravity equation are general, while the empirical performance of the gravity equation is specific to the type of goods examined. Most existing theory for the gravity equation depends on the assumption of differentiated goods. We show...

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...

The literature on multinationals and developing countries has examined the causality" running from direct investment to changes in country characteristics (wages skills, etc.) and also the opposite direction of causality, from existing country characteristics to" inward direct investment. This...

What we term the firm includes three principal assumptions. First, services of knowledge-based and knowledge-generating activities, such as R&D, can be geographically separated from production and supplied to production facilities at low cost. Second, these knowledge-intensive activities are...

The institution and enforcement of property rights and contracts have been an important policy issue for the developing countries, the transition economies, and the developed countries in the 1990s. This has led to the development of a literature on technology transfer and how property rights...

Recent theoretical developments have incorporated endogenous multinational firms into the general-equilibrium model of trade. One simple taxonomy separates the theory into vertical' models in which firms geographically separate activities by stages of production and horizontal' models of...

A model is constructed in which multinational firms may arise endogenously. Multinationals exist in equilibrium when transport and tariff costs are high, incomes are high, and firm-level scale economies are important relative to plant-level scale economies. Less obvious, multinationals are more...

Despite several theoretical contributions and considerable informal empirical evidence" to the contrary, a notion that trade and investment are substitutes persists in trade policy" analysis. This paper considers the liberalization of commodity trade versus liberalization" allowing direct...

This paper contributes to research endogenizing multinational firms in general-equilibrium trade models. We attempt to integrate separate contributions on horizontal multinationals which produce the same final product in multiple locations, with work on vertical multinationals, which...
