This paper provides an empirical comparison of time-varying technical inefficiency measures obtained from the econometric estimation of different specifications of the stochastic production frontier model. Specifically, ten different frontier model specifications, which are most widely used in...

The effects of the 2003 CAP reform on the farmers’ decisions on whether to abandon their farming activity, how much to produce and what to produce are analyzed in the present paper. To this effect data collected for Hungarian, Dutch and Greek farmers on their perceptions about the reform and...

We analyse the impacts of the CAP 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...
