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...

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...

Entry of large ("big-box") stores along with a drastic fall in the number of stores are striking trends in retail. We use a dynamic model to measure the impact of large entrants on productivity, allowing for a controlled productivity process and accounting for prices, local markets, and the...

Quantifying possible inefficiencies stemming from regulation is important to both policymakers and researchers. We use a dynamic structural model to evaluate the role of local market entry regulations in the productivity of retail trade. Our model is flexible with respect to how local market...

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...

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 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...

We study the effects of parallel trade in the pharmaceutical industry. We develop a model in which an original manufacturer competes in its home market with parallel-importing firms. The theoretical analysis results in two key hypotheses. First, if the potential for parallel imports is...

The purpose of this paper is to examine the effects of European integration on the location of investments by Swedish multinational corporations (MNCs). Evidence is presented about the extent to which European integration has attracted investment by Swedish MNCs, and whether foreign direct...
