Computable general equilibrium (CGE) models are a standard tool for policy analysis and forecasts of economic growth. Unfortunately, due to computational constraints, many CGE models are dimensionally small, aggregating countries into an often limited set of regions or using assumptions such 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...

We provide new evidence about the mechanisms linking resource-related income shocks to conflict. To do so, we combine temporal variation in international drug prices with new data on spatial variation in opium suitability to examine the effect of opium profitability on conflict in Afghanistan....

Abstract: The agriculture of the future can only be achieved, in terms of sustainability, and this requires that any development that will be carried out in this area has to be performed in respect of the three pillars: economic, social and environmental. However, in the context of...

This paper explores the empirical relationship between U.S. food aid flows per capita and nonconcessional food availability per capita in PL 480 recipient economies. The evidence suggests PL 480, while modestly progressive in its distribution, is if anything procyclical in recipient economies....

The debate about biotechnology applied to agriculture is one of the most vocal and passionate debates that have been taking place in recent years. This is probably the consequence of the diverging appreciation that people and Governments have of the actual or potential risks and benefits that...
