This paper assesses the effects of international financial liberalization and banking crises on investments and productivity in a sample of 93 countries (at its largest) observed between 1975 and 1999. I provide empirical evidence that financial liberalization spurs productivity growth and...

We study the equilibrium determinants of firm-level heterogeneity in a model in which firms can affect the variance of their productivity draws at the entry stage and explore the implications in closed and open economy. By allowing firms to choose the size of their investment in innovation...

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...

Does economic uncertainty promote the implementation of structural reforms? We answer this question using one of the most exhaustive cross-country panel data sets on reforms in six major areas and measuring economic uncertainty with stock market volatility. To identify causality, we exploit...

We study how financial frictions affect firm-level heterogeneity and trade. We build a model where productivity differences across monopolistically competitive firms are endogenous and depend on investment decisions at the entry stage. By increasing entry costs, financial frictions lower the...

We use French data over the 1994-2013 period to study how imports of industrial robots affect firm-level outcomes. Compared to other firms operating in the same 5-digit sector, robot importers are larger, more productive, and employ a higher share of managers and engineers. Over time, robot...

This paper studies the effect of firms'export activity on the gender wage gap among its workers. Using matched employer-employee data from Germany for the period be- tween 1993 and 2007, we show that an increase in a firm's export widens the wage gap between male and female blue-collar workers,...

International trade is dominated by a small number of very large firms. Models of trade with heterogeneous firms have been developed to study the causes and consequences of this observation. The canonical model of trade with heterogeneous firms shows that trade leads to between-firm...

We study the effect of Artificial Intelligence (AI) on employment across US commuting zones over the period 2000-2020. A simple model shows that AI can automate jobs or complement workers, and illustrates how to estimate its effect by exploiting variation in a novel measure of local exposure to...
