The recent literature on firm-to-firm trade has documented salient empirical regularities of the buyer-seller network. We propose a simplistic re-interpretation of the classical Krugman (1980) model that accounts for surprisingly many of the empirical regularities. This re-interpretation relies...

Over the last decades, the internationalization of the value chain has allowed firms to exploit cross-country differences in environmental and labor regulation (and enforcement) in ways that have led to a large number of NGO campaigns and consumer boycotts criticizing ‘unethical’ practices....

Firms are under increasing pressure to meet stakeholders' demand for Corporate Social Responsibility (CSR) along their global value chains. We study the incentives for and investments in CSR at different stages of the production process. We analyze a model of sequential production with...

We study how occupations shape individual and aggregate retirement behavior. First, we document large differences in individual retirement ages across occupations in U.S. data. We then show that retirement behavior among European workers is strongly correlated with U.S. occupational retirement...

This paper identifies the causal effects of trade shocks on worker outcomes. We exploit a unique setting based on three pillars: (i) a large, unanticipated appreciation of the Swiss franc in 2015, (ii) detailed data with firm-level exposure to trade via output markets (both domestic and foreign)...

We document that observed international input-output linkages contribute substantially to synchronizing producer price inflation (PPI) across countries. Using a multi-country, industry-level dataset that combines information on PPI and exchange rates with international and domestic input-output...

We develop a model of vertical innovation in which firms incur a market entry cost and choose a unique level of quality. Once established, firms compete for market shares, selling to consumers with heterogeneous tastes for quality. The equilibrium of the pricing game exists and is unique within...
