A recent literature has shown that when adoption of a treatment is staggered and average
treatment effects vary across groups and over time, difference-in-differences regression …

We nest an extended two-way fixed effect (ETWFE) estimator for staggered difference-in-
differences within the structural gravity model. To test the ETWFE, we estimate the effects of …

Understanding how personal experience of extreme weather events raises awareness and
concern about climate change has important policy implications. It has repeatedly been …

We study the impact of a healthcare reform that standardized procedures and timely
coverage of a set of diseases. Using Chile's universe of death records and a difference-in …

This study estimates the effect of television exposure in early childhood on subsequent
cognitive outcomes using data from rural China. Exploiting the variations in the year of …

We quantify how competitive funding programs that promote university-industry (UI)
research partnerships affect firm performance. To do this, we estimate staggered difference …

We study the determinants of international cooperation and its effect on trade. We rely on a
unique database of 31,982 International Cooperation Agreements (ICAs) signed between …

This paper develops a framework for estimation and inference to analyze the effect of a
policy or treatment in settings with treatment effect heterogeneity and variation in treatment …

This paper estimates the EMU effect on trade accounting for heterogeneous effects across
space and time. To that end, we use an extended two-way fixed effect estimator for …

We study the impact of a healthcare reform that standardized procedures across health
providers to guarantee the timely coverage of a set of diseases. Using the universe of death …
