This paper uses cross-sectional data collected from 375 smallholder yam farmers in Ghana in 2010 to examine whether the adoption of yam minisett technology had an effect on the technical efficiency of production of the yam farmers. We correct for endogeneity in adoption and employ stochastic...

Purpose: The purpose of this paper is to investigate the characteristics of crop-livestock diversification among smallholders in the forest-savannah agroecological zone of Ghana. Design/methodology/approach: The study uses a stochastic input distance function to investigate the evidence of...

In livestock feeding experiments the problem of recursiveness arises because the quantity of feed consumed by an animal is a function of its past history of feeding. The problem is most acute where experiments are designed to analyse sub ad lib feeding. The analysis of such experiments...

This paper presents a metafrontier production function model for firms in different groups having different technologies. The metafrontier model enables the calculation of comparable technical efficiencies for firms operating under different technologies. The model also enables the technology...

The purpose of this paper is to analyse the impact of the deregulation of the Swedish banking industry in the mid-1980s, and the consequent banking crisis, on productive efficiency and productivity growth in the industry. An unbalanced panel of Swedish banks is studied over the period, 1984 to...

The U.S. Department of Agriculture (USDA) has been responsible for conducting periodic surveys to estimate food consumption patterns of households and/or individuals in the United States for over 50 years. Data from these surveys have had a significant impact on the formulation of...

Farm-level data for the 1988/89 agricultural year from a sample survey of wheat farmers in Eastern Free State, are analysed in this paper. Stochastic frontier production functions are estimated, in which the technical inefficiency effects are modelled in terms of the size of the farming...
