We study, both theoretically and empirically, how export intensity (the ratio of exports to sales) is related to firm productivity. Using a representative sample of Italian manufacturing firms, we find that Total Factor Productivity (TFP) is strongly negatively correlated with export intensity...

We use transaction-level US import data to compare firms from virtually all countries in the world competing in a single destination market. Guided by a simple theoretical framework, we decompose countries' market shares into the contribution of the number of firm-products, their average...

We study how firm and foreign market characteristics affect the geographic distribution of exporterssales. To this purpose, we use export intensities (the ratio of exports to sales) across destinations as our key measures of firmsrelative involvement in heterogeneous foreign markets. In a...

We study the relationship between new imported inputs and the introduction of new domestic products. To this purpose, we assemble a novel data set covering 25 European countries over 1995–2007 and containing information on domestic production and bilateral trade for the universe of goods. We...

We extend the theory of advertising as a quality signal, using a model where an entrant can choose to advertise by comparing its product to that of an established incumbent. Comparative advertising, comparing quality of one’s own product to that of a rival’s, empowers the latter to file for...
