The authors study the link between export product variety and country productivity based on data from 34 industrial and developing countries, from 1982 to 1997. They measure export product variety by the share of U.S. imports on the set of goods exported by each sampled country relative to the...

Product variety plays an important role in the theoretical work on monopolistic competition and trade, and recent empirical work has begun to quantify this for aggregate and disaggregate import demands. The authors discuss the measurement of product variety in trade, using a broad cross-section...

This paper provides evidence on the monopolistic competition model with heterogeneous firms and endogenous productivity. We show that this model has a well-defined GDP function where relative export variety enters positively, and estimate this function over 48 countries from 1980 to 2000....

Trade liberalizations have been shown to improve domestic firms' performance through the new varieties of imported intermediate inputs. This paper uses a unique, representative sample of Bangladeshi garment firms to highlight that local intermediate inputs may also enhance domestic firms'...

China has defied the declining trend in domestic content in exports in many countries. This paper studies China's rising domestic content in exports using firm- and customs transaction-level data. The approach embraces firm heterogeneity and hence reduces aggregation bias. The study finds that...

The short-term impact of Brexit on goods exports is assessed using the Overall Trade Restrictiveness Index of the United Kingdom's major trading partners. The analysis shows that in the short run, leaving the European Union may cause the United Kingdom's exports to the European Union to decrease...
