ABSTRACT

In the article we present the DEA+ method as a tool for estimation of production function and technical efficiency measures. We restrict the scope of the study only to the single-product case. Once the underlying, semiparametric frontier model is discussed, we proceed with demonstrating the very algorithm of DEA+, and provide some critique of its validity. Finally, the method is illustrated with an empirical analysis under certain choices of distributions for each of the random variables constituting the composed error.

KEYWORDS
