Abstract


The assessment of technical efficiency provides information to managers and to policy makers about differences in performance among production units and the potential for improvements. The present work assesses technical efficiency of olive production in Greece and examines the effect of several external factors to this agricultural process. To this end, it relies on panel data from olive farms included in the Farm Accountancy Data Network (FADN) and on robust estimators. This is pursued using recently developed fully non parametric robust partial frontier techniques (the -quantile estimator) which allow for the inclusion of mixed (both continuous and discrete) environmental/exogenous variables
