the technical efficiency involved in cocoa production in cross river state was estimated using the stochastic frontier production function analysis. the effects of some selected socio- economic characteristics of the farmers on the efficiency indices were also estimated. the study relied upon primary data generated from interviewing cocoa farmers using a set of structured questionnaire. a multi...

Determinants, efficiency and potential of agri-food exports from Nigeria to the EU: Evidence stochastic frontier gravity model | Nazir Muhammad Abdullahi, Olufemi Adewale Aluko, Xuexi Huo Agricultural Journals

In this paper we develop and implement a methodology for analysing the sources of variation in environmental efficiency across producers. We formulate a two-stage model. In the first stage we use stochastic frontier analysis to estimate both technical and environmental efficiency. In the second stage we again use stochastic frontier analysis to regress estimated environmental efficiency scores ...

The estimation of frontier cost and production functions has been given impetus by the introduction of the stochastic frontier.’ This model is distinguished by a disturbance term composed of two parts a one-sided component, non-positive for production functions and non-negative for cost functions, representing the degree of inefficiency, and a symmetric component representing the usual statisti...
