reforms on technical  efficiency of Greek olive farms. We use a production  frontier function and a non-monotonic inefficiency effects  model which incorporates the influences of exogenous  variables on the mean and the variances of farm efficiency.  We formulate policy variables (e.g. the direct subsidies)  and farm characteristics as explanatory variables in the  inefficiency effects model. We use the 1995-2004 FADN data  to estimate the production frontier, to derive technical  efficiency, and to determine the effects of the explanatory  variables. The study shows that the 10-year average  technical efficiency of olive farms is 69%. Direct  transfers have a negative and monotonic effect on technical  efficiency, while the degree of specialization has a  non-monotonic effect on technical efficiency.},
