While there is a growing literature on the impact of climate and weather-related events on migration, little is known about the mitigating effect of different policies directed to the agricultural sector, or aimed at insuring against environmental disasters. This paper uses state-level data on...

Trade data are typically reported at the level of regions or countries and are therefore aggregates across space. In this paper, we investigate the sensitivity of standard gravity estimation to spatial aggregation. We build a model in which initially symmetric micro regions are combined to form...

We estimate the short-run effects of severe weather shocks on local economic activity and assess cross-border spillovers operating through economic linkages between U.S. states. We measure weather shocks using a detailed county-level database on emergency declarations triggered by natural...

We investigate how fertility and demographic factors affect migration at the household level by assessing the causal effects of sibship size and structure on offspring's international migration. We use a rich demographic survey on the population of Mexico and exploit presumably exogenous...

Borders have a sizable negative impact on trade flows. Given the vast number of individual goods potentially traded, this "border effect" could have two possible explanations: (1) less international than domestic trade in the goods that are actually traded between countries ("flow"), or (2)...

Many studies have found that international borders represent large barriers to trade. But how do international borders compare to domestic border barriers? We investigate international and domestic border barriers in a unified framework. We consider a unique data set of exports from individual...
