Accounting for self-selection bias in assessing impacts of agricultural innovations : the case of farmer support programs in the Eastern Cape
… Cape, this study estimates a Cobb-Douglas stochastic production frontier and uses it to compare the efficiency scores of the two farmer types. The results show that FSP adopters had relatively higher TE scores, with over 50% having scores of above 70%. However, a t-test for equality of mean …

Optimum experimental designs for models with a skewed error distribution: with an application to stochastic frontier models
… type is sometimes called 'composed' error. A stochastic frontier model is an example of a model that possesses such an error structure. The systematic error, U, in a stochastic frontier model represents the economic efficiency of an organisation. Three methods for approximating information …
