We leverage a comprehensive dataset of electronic invoices from Chilean firms to document new facts on price dispersion across buyers of manufactured intermediate goods. Over half of firm-to-firm manufacturing sales are accounted for by products that are purchased by more than one buyer in the...

We revisit a central question for international macroeconomics: the response of export prices and quantities to movements in the exchange rate (ER). We use granular export data for Chile and study how the effects of ER movements vary over time with the currency of invoicing and the destination...

This paper uses barcode-level price data for 16 advanced and emerging market countries over the period 2005-2022 to investigate the role of individual firms and product categories in aggregate inflation. We decompose inflation into the component due to macroeconomic shocks and the granular...

This paper estimates and quantifies the impact of the diaspora remittance flows on the conflict intensity and outcomes in the Sri Lankan Civil War during the period 1996-2009. We develop an approach to infer which remittance inflows were likely to benefit the Tamil Tiger rebels relative to the...

We study the roles of globalization and structural change in the evolution of international GDP comovement among industrialized countries over the period 1978-2007. In recent decades, trade integration between advanced economies increased rapidly while average GDP correlations remained stable....

We quantify the contribution of the largest firms to South Korea's economic performance over the period 1972-2011. Using firm-level historical data, we document a novel fact: firm concentration rose substantially during the growth miracle period. To understand whether rising concentration...

Yes. We state closed-form expressions for steady state gains from trade that apply in a class of dynamic trade models that includes dynamic versions of the Krugman (1980), Melitz (2003), and customer capital (e.g., Arkolakis, 2010) models. The gains are a function of the domestic trade share and...

This paper studies the cross-country patterns of risky innovation and growth through the lens of international trade. We use a simple theoretical framework of risky quality upgrading by firms under varying levels of financial development to derive two predictions. First, the mean rate of quality...
