This paper develops a model in which upstream network insiders' conduct relationship specific investment that induces the downstream firm to transact within networks. The scale of destination-country production and part-specific measures of the importance of network relationships and engineering...

This paper investigates the effect of endogenous horizontal product differentiation on trade patterns and the gains from trade under Bertrand and Cournot oligopoly. Firms differentiate their products to mitigate competition, but only if the investment required is not too high. Investment in...

This paper provides a new and simple model of endogenous horizontal product differentiation based on a standard demand structure derived from quadratic utility. One objective of the paper is to explain the "empirical Bertrand paradox" - the failure to observe homogeneous product Bertrand...

Recent research has demonstrated the importance of institutional quality at the country level for both the volume of trade and the ability to trade in differentiated goods that rely on contract enforcement. This paper takes advantage of cross-provincial variation in institutional quality in...

Large firms played a central role in the “new trade” models that became a major focus of trade economists in the early 1980s. Subsequent literature for the most part kept imperfect competition but jettisoned oligopoly. Instead, as the heterogeneous firms literature burgeoned in the 2000s,...

In a model where upstream network insiders conduct relationship-specific investment, downstream firms have an incentive to transact within networks. Evidence from U.S. auto parts exports to 26 auto-producing countries supports key predictions of the model. Greater production scale for assemblers...
