I present a model of international trade and foreign direct investment (FDI), where FDI is comprised of greenfield FDI and mergers and acquisitions (M&A). Working in a monopolistically competitive environment, merging firms do not reduce competition. Mergers are motivated by efficiency gains and...

Both proximity-concentration trade-off and factor proportions explanations have been forwarded to explain the existence of multinational enterprises. This paper analyses to what extent these different explanations are supported empirically, in making a first attempt to distinguish explicitly...

This paper investigates whether European integration has an effect on the geographical concentration of Swedish multinationals' production inside the European Union. The results indicate that agglomeration and dispersion forces are present, and that the relative strength of these forces has been...

This paper analyses the effects of the Single European Market and Swedish Investment liberalisation on the structure of Swedish multinationals with their EU affiliates. The empirical results suggest that the determinants associated with horizontal and vertical multinationals have become...

We develop a two-country general equilibrium model where firms make separate choices about the location of R&D and high-tech production. There are two agglomeration forces: R&D spillovers and backward linkages associated with high-tech production. The latter tends to attract production to the...

In this paper, we present a standard quality ladders endogenous growth model with one significant new assumption, that it takes time for firms to learn how to export. We show that this model without Melitz-type assumptions can account for all the evidence that the Melitz (2003) model was...

This paper analyses the effects of non-tariff barriers, in terms of both variable and fixed export costs, on trade structure. The relationship between fixed and variable trade costs determines whether international trade emerges. If trade emerges, only variable, but not fixed export costs,...

This paper examines if international trade can reduce total welfare in an international oligopoly with differentiated goods. We show that welfare is a U-shaped function in the transport cost as long as trade occurs in equilibrium. With a Cournot duopoly trade can reduce welfare compared to...

This paper studies the effect of production subsidies used as strategic instruments by two rivalling countries whose firms differ in production efficiency. In particular, it examines the welfare effects of a uniform subsidy reduction from the Cournot-Nash equilibrium under different assumptions...

This paper analyses the effects of non-tariff barriers, in terms of both variable and fixed export costs, on the structure of trade and industry. We find that the relationship between fixed and variable trade costs affects industrial structure and determines whether international trade emerges....
