The aim of this paper is to analyze total factor productivity growth in agriculture for six Central Eastern European Countries (CEECs) and the current EU-15 member states. The purpose is to determine whether both the CEECs and EU-15 members followed similar productivity growth patterns in agriculture. Our measure of productivity growth relies on the Malmquist Index (MI) introduced by Caves et al. (1982). In order to test for a frontier separation between the 6-CEECs and the EU-15 members we follow the work of Grosskopf and Valdmanis (1987) and its development in Fizel and Nunnikhoven (1992). To preserve stability, the frontier separation approach is combined with the intertemporal production set notion, a technique developed by Tulkens and Vanden Eeckaut (1995). We find the average annual change in agricultural productivity to increase at almost 1.5 percent per annum over the considered period 1993-2000. On average the annual productivity increase for the EU-15 member states was higher than that of the CEECs. It appears that there was a remarkable difference between the frontier of the 6-CEECs and the EU-15 countries, which signals that both sub-groups belonged to a different frontier.
