This paper employs Data Envelopment Analysis and Stochastic Frontier Analysis to examine the technical efficiency of the agricultural sectors of the Central and Eastern European accession Countries (CEECs) during the period 1998-2001. The results indicate that the agricultural sectors of many accession countries are both technically inefficient and scale-inefficient. The analysis of changes in total factor productivity suggests slow rates of adoption of technical progress, declining technical efficiency of agricultural enterprises and, as a result, less efficient use of existing technologies and resources during the considered time period.
