An application of the double-bootstrap data envelopment analysis to investigate sources of efficiency in the Greek poultry sector

This paper reviews a double-bootstrap data envelopment analysis of the performance of the Greek poultry sector for the period of 1994–2007. The purpose for implementing this method is to obtain consistent inferences in measuring technical efficiency and in identifying its determinants. The findings suggest that on average, technical inefficiency is present in the Greek poultry industry.   Under the variable return to scale specification, technical efficiency decreased to 90% in 2007 from 94%
