Projections of future crop yields are highly uncertain. At global to regional scale, CO2 fertilization has the potential to generally increase crop yields on current crop land. However, it is highly unlikely that yield increases due to CO2 fertilization will be fully achieved in most regions, as...

Global gridded crop models (GGCMs) are the workhorse of assessments of the agricultural impacts of climate change. Yet the changes in crop yields projected by different models in response to the same meteorological forcing can differ substantially. Through an inter-method comparison, we provide...

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