World trade evolves at two margins. Where a bilateral trading relationship already exists it may increase through time (intensive margin). But trade may also increase if a trading bilateral relationship is newly established between countries that have not traded with each other in the past...

Climate research suggests that global warming will lead to more frequent and more extreme natural disasters. Most disasters are local events with effects on local economic growth. Hence, assessing their economic impacts with the help of econometric country-level analysis may lead to biased...

Recent disruptions to global value chains (GVCs) have raised an important question: Can decoupling from GVCs increase a country’s welfare by reducing its exposure to foreign supply shocks? We use a quantitative trade model to simulate GVCs decoupling, defined as increased barriers to global...
