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...

This paper analyses the effect on agglomeration tendencies of allowing firms to become multi-region firms in a standard model of trade and location. More specifically, we introduce horizontal and vertical multi-region firms into the core-periphery (CP) model developed by Krugman (1991). The...

This paper takes a step towards formalizing the theoretical interconnections among four post-Indutrial Revolution phenomena - the industrialization and growth take-off of rich 'northern' nations, massive global income divergence, and rapid trade expansion. Specifically, we present a...

The paper demonstrates how trade between developing countries can cause the divergence of long-run growth among these countries. The model describes two symmetric countries trading with each other and the industrial rest of the world. Bilateral trade occurs at any moment if the countries have...

The paper estimates the causal effect of trade liberalisation on aggregate productivity through mechanisms related to firm selection. The construction of a bridge in 2000 across the Öresund Strait linking Copenhagen with Malmö, Sweden's third largest city, provided a natural experiment with...

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...

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...
