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...

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 presents a dynamic general equilibrium model of trade between two advanced countries in which both innovation and skilled acquisition rates are endogenously determined. The model offers a North-North (as opposed to a North-South) trade explanation for increasing relative wage...

Previous research has been inconclusive as regards the effect of outward foreign direct investment (FDI) on domestic investments. In this article we show that this inconclusiveness can be explained at a disaggregated level as a function of the way industries are organized. Based on a simple...

Standards and technical regulations which govern the admissibility of imported goods into an economy raise costs of exporters entering new markets, and may have a particularly high impact on firms seeking to export from developing countries. Yet standards may also have a positive side, such as...

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...

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...
