To satisfy continued growth in food demand without further degrading already low fertility soils or extensifying onto fragile margins, African farmers must pursue "sustainable agricultural intensification" (SAI). SAI requires adequate use of capital to maintain soil fertility and conserve the...

This paper introduces a systematic but simple approach to classifying and ordering sources of risk faced by subject populations. By distinguishing between the incidence and severity of subjective risk perceptions, this method enhances understanding of the nature and variation of risks faced...

This paper studies variation in risk assessment by pastoralists in the arid and semi-arid lands of southern Ethiopia and northern Kenya. Despite superficial homogeneity among east African pastoralists, we show that there exists considerable within-group heterogeneity in their assessment of...

This article strategically surveys the past century’s literature on agricultural development. We organize the discussion around three “grand themes” that reveal the richness of agricultural development as an intellectual endeavor. First, we explore the role of agriculture in the broader...

There is a large literature on the estimation of frontier production functions, much of it applied to low-income agriculture. However, much of this literature largely ignores nature's role in agricultural production. Because exogenous, natural production conditions (e.g., rainfall, soil quality,...

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....

This paper introduces a method for estimating structural labor supply models in the presence of unobservable wages and deviations of households' marginal revenue product of self-employed labor from their shadow wage. This method is therefore remarkably robust to a wide range of assumptions about...

This paper offers an overview for a special issue on agroindustrialization, globalization, and international development. It sets out a conceptual framework for understanding the links among these three broad phenomena and then discusses emerging issues and evidence concerning the factors...

This paper introduces a method for estimating structural labor supply models in the presence of unobservable wages and deviations of households' marginal revenue product of self-employed labor from their shadow wage. This method is therefore robust to a wide range of assumptions about labor...

This paper develops a model coupling wildlife population dynamics to endogenous human consumption and poaching behavior in an environment of imperfect labor and product markets and static agricultural production technology subject to environmental shocks. Using a model of the Serengeti...
