This study uses a multivariate probit model and the Poisson regression to examine the role of varietal attributes in farmers’ adoption of improved pigeon pea (Cajanus cajan) varieties in Taita District, Kenya. It is based on data collected from 200 h...
Rural households in sub-Saharan Africa face many risks and are therefore often vulnerable to poverty. Income diversification has been proposed as a potentially effective strategy to mitigate their risks. This paper explores how portfolio decisions of...
Research in agriculture, agricultural economics and rural development is essential if we are to find ways to feed the increasing population and reduce poverty. Yet much of this research goes unpublished. This paper proposes an effective way to increa...
This article empirically assesses the effect of unobserved transaction costs for Nigerian farmers when investing in irrigation pumps. The unobserved stochastic threshold (UST) model popularly used in labor economics literature is applied, and is comp...
This study estimates inter-fuel substitution elasticities and long-run substitution elasticities between energy and non-energy aggregate inputs used by production sectors in Malawi. All fuels are Morishima substitutes but there are significant sector...
Vitamin and mineral deficiencies are a significant health problem in much of the developing world, causing illness, disability, mortality and reduced productivity. Biofortification of staple food crops has been proposed as a cost-effective solution....
Farm productivity in the Peanut Basin of Senegal has been declining over time, requiring strategic interventions to reverse this trend. Using pooled cross-section time-series data and probit and Tobit models, this paper examines factors that influenc...
Uganda’s National Agricultural Advisory Services (NAADS), established in 2001, is a demand-driven extension program for developing farmer organizations and improving farmer production and welfare. The program is expected to be 50% client funded after...
The conventionally used equilibrium displacement model (EDM) provides a convenient way to estimate the distribution of welfare gains from crop productivity growth across different population groups. However, it ignores the high market margin. Little...
This study provides empirical evidence on the effects of production risk on smallholder farmers’ adoption of farm technology, using plot-level data collected from two semi-arid districts in Kenya, Machakos and Taita Taveta. Using Mundlak’s approach (...
Malian farmers have been cultivating millet and sorghum for millennia, but they are slow to adopt and develop modern varieties because it is difficult to observe the difference in yields in their fields, given the challenging local growing conditions...
This paper analyzes the demand for meat in Egypt for the period 1990–2005 using the linearized Almost Ideal Demand System to estimate own-price, cross-price and expenditure elasticities. It found that the Marshallian own-price elasticity was the high...
