A procedure is developed to examine the ex-post impacts of improved maize varieties on poverty in rural Ethiopia. Yield and cost effects of adoption are estimated econometrically under assumptions of both homogeneous and heterogeneous treatment effects. A backward derivation procedure is...

Adoption of agricultural technology can lead to multiple benefits to farm households, including increased productivity, incomes and food consumption. However, specific causal linkages between agricultural technology adoption and child nutrition outcomes are rarely explored in the literature....

This article evaluates the impact of the adoption of improved wheat varieties on food security using a recent nationally-representative dataset of over 2000 farm households in Ethiopia. We adopted endogenous switching regression treatment effects complemented with a binary propensity score...

Since the beginning of 1970’s, more than 40 improved maize varieties have been released and disseminated to maize potential areas in Ethiopia. Using cross-sectional survey data collected in 2011 from 39 districts in five Regional States, this paper examines smallholder farmers’ knowledge,...

Soil fertility depletion is considered the main biophysical limiting factor to increasing per capita food production for most smallholder farmers in Africa. The adoption and diffusion of sustainable agricultural practices (SAPs), as a way to tackle this impediment, has become an important issue...

Crop residue use for soil mulch and animal feed are the two major competing purposes and the basic source of fundamental challenge in conservation agriculture (CA) where residue retention on farm plots is one of the three CA principles. Using survey data from Kenya and applying bivariate ordered...

Conservation agriculture has many potential benefits for small farmers. This study seeks to estimate the value that farmers in eastern Uganda place on some these benefits. Data from a choice experiment study are analyzed with a mixed logit model to determine farmers’ willingness to pay for...

Health disparities are abundantly recorded in literature, but is much less understood within a rural-urban context. In this paper, four major diseases in Virginia are studied: cancer, stroke, cardiovascular disease (heart disease) and chronic obstructive pulmonary disease (COPD). Separate count...

In this paper, a framework is developed to analyze how the specifications of new technologies and the heterogeneity of micro-units of production affect the input use, the adoption pattern, and the productivity of inputs. It shows that asset-productivity-enhancing (APE) technologies tend to be...
