Since independence a quiet revolution has taken place in maize production in the Sahel with Mali increasing production more than ten-fold and yields going up ~2% a year. This research work uses farm level panel data from southern Mali's maize growing regions to demonstrate this success in...

Cotton yields in Mali have fallen during the past 15 years while maize yields have risen. The objective of this study is to examine key changes in the agricultural system to understand how these changes might have influenced the production of these key crops. In particular, this study seeks to...

To raise awareness among policymakers and health practitioners about unhealthy diets, this document examines dietary patterns in selected Latin American countries using household surveys. The analysis shows that a large percentage of households in the countries examined have inadequate diets....

Genetically modified corn seed companies have innovated continuously with the introduction of new traits and, more recently, with the creation of stacked varieties. This work develops a Bayesian model of adoption that demonstrates how uncertainty with a package technology can lead to a...
