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 Yet much of this research goes unpublished.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 increase publication productivity, based on...

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 compared with two models, the Tobit and the...

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 fishery-dependent households in Cameroon...

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 research has been done on the potential bias...

The problems of pastoralist livestock marketing systems in East Africa are well-documented in the literature. They include poor transport infrastructure, inadequate market access and frequent rejection of animals at certain markets. Thus far, few studies have analyzed the effects of eliminating...

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. This paper calculates disabilityadjusted life...

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 sectoral variations in the magnitude of the...

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 influence the decision whether or not to use...

L’objectif principal de ce travail est d’analyser l’impact du changement climatique sur la productivité des cultures céréalières dans la région de Béja, située au nord-ouest de la Tunisie. Pour ce faire, des modèles de régression multiple ont été estimés pour trois cultures...

This paper examines the long-term effects of shocks experienced by a traditional pastoral community, with the aim of testing the micro-level poverty trap hypothesis. It uses the instrumental probit technique to examine empirically the way that shocks, poverty traps, and the social capital base...
