In this study, we explain a half-century of crop yield growth along an 800-mile transect of the forty-first parallel North in the U.S. Great Plains. Using 101 county-level observations from 1960-2008 we jointly estimate a biomass production function with cost shares for fertilizer and chemicals while controlling for environmental factors. The main contributors to yield increases in this region were non-specific technical change +62%, irrigation +17%, fertilizer +13% and chemicals +11%. Environmental changes had a minor impact on regional yield changes. The wide range of agroclimatic conditions present along this transect produced significant sub-regional deviations from the aggregate estimates. While …

Purpose--The paper theoretically and empirically investigates the impact on human capital investment decisions and income growth of lowered life expectancy as a result of HIV/AIDS and other diseases. Design/methodology/approach--The theoretical model is a three-period overlapping generations model where individuals go through three stages in their life, namely, young, adult and old. The model extends existing theoretical models by allowing the probability of premature death to differ for individuals at different life stage, and by allowing for stochastic technological advances. The empirical investigation focuses on the effect of HIV/AIDS on life expectancy and on the role of health on educational investments …
