Immigrants may expand trade with their country of origin, owing to superior knowledge of, or preferential access to, market opportunities. The authors test this proposition using Canadian trade data with 136 partners from 1980 to 1992. In an augmented gravity equation, they find that a 10...

Recent theories of economic geography suggest that firms in the same industry may be drawn to the same locations because proximity generates positive externalities or 'agglomeration effects.' Under this view, chance events and government inducements can have a lasting influence on the...

Paul Krugman's model of trade predicts that the country with the relatively large number of consumers is the net exporter and hosts a disproportionate share of firms in the increasing returns sector. He terms these results "home market effects". This paper analyses three additional models...

Knickerbocker (1973) introduced the notion of oligopolistic reaction to explain why firms follow rivals into foreign markets. We develop a model that incorporates central features of Knickerbocker's story-oligopoly, uncertainty, and risk aversion-to establish the conditions required to generate...

The majority of independent nations today were part of empires in 1945. Using bilateral trade data from 1948 to 2006, we examine the effect of independence on post-colonial trade. On average, there is little short run effect of trade with the colonizer (metropole). However, after three decades...

Krugman's model of trade between two countries of unequal size predicts that the country with the relatively large number of consumers is the net exporter and host of a disproportionate share of firms in the differentiated good sector. He terms these results home market effects. This paper...

A firm can serve overseas customers by exporting or by producing in the foreign market. Thus, ceteris paribus, one might expect increases in overseas investment to displace exports. However, most empirical work has found a positive relation between the two variables. The authors use a panel...
