CONDITIONAL EFFICIENCY ESTIMATION WITH ENVIRONMENTAL VARIABLES: EVIDENCE FROM GREEK CEREAL FARMS

Abstract

The objective of this paper is to assess technical efficiency of cereal production in Greece in a nonparametric framework while accounting for a set of exogenous variables. To this end, we implement robust partial frontier techniques on a sample of cereal-producing farms included in the Farm Accountancy Data Network (FADN). Moreover, we assess the partial impacts of the environmental variables using non parametric regression tools.
