|September 2016||Better, Faster, Stronger: Global Innovation and Trade Liberalization|
with Federica Coelli, Andreas Moxnes: w22647
This paper estimates the effect of trade policy during the Great Liberalization of the 1990s on innovation in over 60 countries using international firm-level patent data. The empirical strategy exploits ex-ante differences in firms' exposure to countries and industries, allowing us to construct firm-specific measures of tariffs. This provides a source of variation that enables us to establish the causal impact of trade policy on innovation. Our results suggest that trade liberalization has economically significant effects on innovation and, ultimately, on technical change and growth. According to our estimates, about 7 percent of the increase in knowledge creation during the 1990s can be explained by trade policy reforms. Furthermore, we find that the increase in patenting reflects innova...
|May 2014||Two-Sided Heterogeneity and Trade|
with Andrew B. Bernard, Andreas Moxnes: w20136
Empirical studies of firms within industries consistently report substantial heterogeneity in measures of performance such as size and productivity. This paper explores the consequences of joint heterogeneity on the supply side (sellers) and the demand side (buyers) in international trade using a novel transaction-level dataset from Norway. Domestic exporters as well as foreign importers are explicitly identified in each transaction to every destination. The buyer-seller linked data reveal a number of new stylized facts on the distributions of buyers per exporter and exporters per buyer, the matching among sellers and buyers and the variation of buyer dispersion across destinations. The paper develops a model of trade with heterogeneous importers as well as heterogeneous exporters where ma...
