This research explores the origins of the distribution of time preference across regions. It advances the hypothesis, and establishes empirically, that geographical variations in natural land productivity and their impact on the return to agricultural investment have had a persistent effect on...

We estimate annual discontinuities in remotely-sensed crop yields at all international land borders and link them to changes in the economic freedom index by the Fraser Institute, a country-level measure of institutional quality. Each point of the ten-point index increases the discontinuity by...

This paper analyzes the short-run trade effects of retaliatory tariffs against agriculture and food exports from the United States. The results indicate that these tariffs caused a substantial decline in U.S. agriculture and food exports and induced a reorientation of international trade...

The recent rise in caloric undernutrition in Sub-Saharan Africa (SSA) demonstrates the continued relevance of the Malthusian footrace between food availability and population. Sluggish growth in farm productivity in SSA has brought to the fore the key role of agricultural technology in...

Do governments systematically intervene in agricultural markets in response to climate shocks? If so, what are the aggregate and distributional consequences? We construct a global dataset of agricultural policies and extreme heat exposure by country and crop since 1980. We find that extreme heat...
