This article investigates the effects of wheat genetic diversity and land degradation on risk and agricultural productivity in less favored production environments of a developing agricultural economy. Drawing production data from a household survey conducted in the highlands of Ethiopia, we...

This paper investigates the dynamic effects of rainfall shocks on agroecosystems productivity. The analysis estimates a panel data model of cereal production in southern Italy. It documents the adverse effects of a reduction in rainfall on the agroecosystem productivity both in the short run and...

This paper investigates the effects of crop genetic diversity on farm productivity and production risk in the highlands of Ethiopia. Using a moment-based approach, the analysis uses a stochastic production function capturing mean, variance, and skewness effects. Welfare implications of diversity...

This paper investigates the productive value of crop biodiversity, with an application to a farming system in the Tigray region in the highlands of Ethiopia. We examine a general measure of the productive value of crop biodiversity and its components. Using Ethiopian farm-level data,...

This paper presents an assessment of the linkages between crop genetic diversity, farm productivity and risk management. A flexible moment-based approach is used to analyse the impact of crop genetic diversity on the mean, variance and skewness of yield. Using farm-level data from Sicily...
