%0 Journal Article %T CONDITIONAL EFFICIENCY ESTIMATION WITH ENVIRONMENTAL VARIABLES: EVIDENCE FROM GREEK CEREAL FARMS %A Sofia KOURTESI %A Panos FOUSEKIS %A Apostolos POLYMEROS %J Scientific Bulletin : Economic Sciences %D 2012 %I University of Pitesti %X 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. %K Nonparametric estimation %K conditional efficiency %K cereal farms %U http://economic.upit.ro/repec/pdf/2012_1_5.pdf
