The reverse home-market effect in export. A cross-country study of the extensive margin of exports

Do small countries have higher proportions of firms that export in manufacturing industries than large ones? As small countries are well known to be more open than large ones, it may appear uncontroversial to claim that the answer is yes. Nevertheless, this contradicts predictions from many standard trade models positing a home-market effect in the number of manufacturing firms and exporters. In this article, I present a theoretical model where a home-market effect in the number of firms coexists with a reverse home-market effect in the number of exporters: as in standard models, the number of firms in a small country relative to that in a large one is lower than relative income, but, in contrast to standard models, the relative number of exporters is larger. As a consequence, small countries will have higher proportions firms that export in manufacturing industries – a claim I support empirically.

Learning, Networks and Sunk Costs in International trade: Evidence form Norwegian Seafood Exports

Based on new survey data for 81 Norwegian seafood exporters, the report examines the composition and magnitude of different types of trade costs, ranging from tariffs and transport costs to other sales costs. The results suggest that there are economies of scale in the exporting activity, due to fixed costs of market entry, learning through experience, and externalities between firms so that one exporter benefits from the others via learning or joint marketing effects. Seafood exports strongly rely on personal networks, and firms incur costs in order to establish these networks. On the whole, however, fixed sales costs for seafood exports are small, due to these products being relatively homogeneous. In spite of this, such costs matter for the choice of markets and the magnitude of trade. The report analyses how costs vary across products, firms and markets. For seafood exports, traditional trade barriers such as tariffs and transport costs are more important than the sunk costs. Transport costs do not increase proportionally with geographical distance, mainly since this is not the case for sea transports.
