We develop a simple model of financial intermediation with search and matching frictions between banks and firms. The model links credit market tightness - encapsulating the abundance of credit - to the search and opportunity costs of credit intermediation. Search costs generate lending to...

This paper studies how credit guarantee and employment protection programs interact in assisting firms during crises times. The paper analyzes how these government programs influence credit allocation, indebtedness, and risk at both the micro and macro levels. The programs provide different...

To test the localized tastes hypothesis, we use historical dialect similarity as an instrument to predict the persistent component of regional taste differences. Analyzing wholesale markets for fruits and vegetables in Japan, we find that predicted taste differences have a strong, statistically...

This paper investigates the cyclicality of international reserves and their role in macroeconomic stabilization. We challenge two widely held assumptions: (1) central banks typically manage IR counter-cyclically—accumulating reserves during booms and drawing them down during downturns; and (2)...

This paper investigates the impact of social media algorithms on mental health outcomes. I exploit a quasi-experimental setting combining data from the Dutch Longitudinal Internet Studies for the Social Sciences (LISS) coupled with the introduction of the algorithmic feed on Instagram in 2016.

How does dismantling deep integration affect international trade? This paper provides new evidence on the consequences of disintegration by estimating the impact of Brexit on goods trade by UK firms. The UK’s exit from the EU’s single market and customs union in January 2021 led to an...

Defensive hiring of researchers by incumbent firms with monopsony power reduces creative destruction. This mechanism helps explain the simultaneous rise in R&D spending and decline in TFP growth in the US economy over recent decades. We develop a simple model highlighting the critical role of...

We study how demand uncertainty affects risk-neutral firms. number of export destinations when uncertainty is resolved after firms choose their export destinations and output. We show that firms’ ability to allocate their output across destinations in response to destination-specific shock...

We study the causal effect of country-specific democratic regime change on bilateral trade flows, extending structural gravity empirics to ‘heterogeneous gravity’ estimated at the country-pair level. Our difference-in-differences implementation accounts for selection into regime change,...

This study investigates the impact of U.S. economic sanctions on internal instability and conflict using a global sample. Our analysis, which includes cross-country and panel data from over 120 countries between 1996 and 2022, shows that economic sanctions increase the risk of internal conflict...
