This study examines economic performances and household’s behaviours in multiple crops farming in Vietnam. Smallholder farming systems in Vietnam is being transformed by integration between cash cropping and main food cropping operations. This transformation into diversified farming systems...

This article offers a methodology to address the endogeneity of inputs in the input distance function (IDF) formulation of the production processes. We propose to tackle endogenous input ratios appearing in the normalized IDF by considering a flexible (simultaneous) system of the IDF and the...

This paper investigates the impacts of land fragmentation on economic diversity of farm households in Vietnam. To develop the empirical analysis, a model is presented in which the estimated impact of land fragmentation on economic diversification allows for non-neutral technical change. The...

Various South African policy statements and strategy proposals argue that farmer focused planning and farming systems research approaches are required to develop policies, strategies and project activities to serve farmers efficiently. Then, the question is how to give a practical content to...

This paper assesses the causal effect of relaxing equity constraints on the cultivation of tobacco in Malawi, a crop viewed by the local population as Malawi’s green gold. Applying the counterfactual outcome framework we find that relaxing equity constraints substantially increases the amount...

Radical changes took place with respect to several agricultural policies in Ethiopia in 1990-91. Different agricultural technologies were being delivered by several international agencies. Shifts in government policies and technological intervention would induce changes in the production...

Multidisciplinary research methods such as observatory, participatory and multivariate regression analysis were employed to examine goals and strategies of two peasant communities in the Central highlands of Ethiopia. Continuing the family tradition of participating in social networks is found...

An aggregate measure of production efficiency involving crop and livestock enterprises is examined in the Selale and Ada regions of Ethiopia using Data Envelopment Analysis (DEA). In general, farmers in regions more suitable to crop production (Ada) tend to attain higher production efficiency...

During the mid-1990s, the Government of India and the World Bank began exploring new approaches to extension that would address these system problems and constraints. The result was a new, decentralized extension approach, which would focus more directly on agricultural diversification and...

Moore suggested an exponential growth of the number of transistors in integrated electronic circuits. In this paper, Moore’s law is derived from a preferential growth model of successive production technology generations. The theory suggests that products manufactured with a new production...
