A stochastic frontier model is proposed for analysis of crop yields, which considers the effects of differing quality of irrigation water, in addition to different inputs and factors associated with technical inefficiency of production. The parameters of the production frontier involved are...

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...

Two models of technical inefficiency with a stochastic production frontier are considered in this paper. In the first model, it is assumed that the frontier itself does not vary with time, while in the second, the frontier is allowed to move. These models are applied to four years of panel data...

The parameters of the distribution of usual intakes of calcium, energy, iron, protein and vitamin C are estimated using four daily intakes of these dietary components for a sample of women selected in the Continuing Survey of Food Intakes by Individuals, conducted in 1985-86 by the Human...

Agglomeration externalities can have positive effects on both the production possibility frontier and technical inefficiency of firms. Increased levels of localized knowledge spillovers and substitution of internal inputs with external inputs may lead to fewer errors in decision-making and...
