The multinational firm (MNF) is introduced as the intersection between trade theory and the theory of the firm. I show that economies of scale associated with various knowledge inputs have made it possible for firms to grow large through internationalization and, once large, staying competitive...

Recent empirical evidence suggests that prices for some goods and services are higher in larger markets. This paper provides a demand-side explanation for this phenomenon when firms can choose how much to differentiate their products in a model of monopolistic competition with horizontal product...

The theory of the firm suggests that firms can respond to poor contract enforcement by vertically integrating their production process. The purpose of this paper is to examine whether firms' integration opportunities affect the way institutions determine international trade patterns. We find...

This paper shows that the R&D intensity of an industry plays an important role in determining international trade patterns via its e¤ect on scale economies. I first develop a model of trade with heterogeneous firms where firms compete with each other by spending on fixed product development...

The theory of the firm suggests that firms can respond to poor contract enforcement by vertically integrating their production process. The purpose of this paper is to examine whether firms’ integration opportunities affect the way contract enforcement institutions determine international...

These notes discuss some of the main results and models from the theory of international trade under imperfect competition. They are necessairy both selective and superficial. Multinationals are conspicuous by their absence, and the reader is referred to Markusen (1995) for a recent survey. Up...

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...

Recent theoretical analysis suggests that a reduction in the cost of exporting increases the degree of assortative matching between workers and firms in export-oriented industries. Changes that reduce the cost of imports have an ambiguous impact on matching. We combine detailed Swedish matched...

The origin of this paper was the need to provide import and export functions for the IUI-model of the Swedish economy used in the 1979 forecasting exercise, later on extended to support the analysis in the KRAN-project. This paper summarizes the results of the estimates of price elasticity’s...
