| This paper employs bootstrapping to correct for bias and to construct confidence intervals for Malmquist TFP indices derived with DEA. It uses these results to investigate the productivity change in Polish agriculture during a crucial period of the country's transition to a market economy, 1996-2000, when Poland was preparing for accession to the European Union. The bias corrected estimates show regress in productivity at an annual rate of 4 percent. The confidence intervals suggest that between two-thirds and four-fifths of the sample farms (250) in different years might have experienced no change in productivity. The cluster analysis based on confidence bounds reveals three paths of productivity change. Farms which recorded an increase in productivity at... |

| The paper investigates the difference in technical efficiency and in productivity change, and the technology gaps, between French and Hungarian farms in the dairy and cereal, oilseeds and proteinseeds (COP) sectors during the period 2001-2004. The analyses are performed with national FADN data and the Data Envelopment Analysis (DEA) approach under each country’s respective frontier and under a metafrontier. Results revealed that in both the dairy and the COP sectors, Hungarian farms’ technology was the more productive, despite a technological deterioration. This suggests technological advantages for large-scale (Hungarian) over small-scale (French) farming in these two sectors. These findings may also be explained by the higher policy support in France.... |

| This paper provides an assessment of the extent to which targets set by a public authority are achieved by its operational units. A rare DEA framework and its subsequent Malmquist indices are applied on data comprising 19 units over a four year period of 1996 to 1999. The mean efficiency scores by which targets are achieved across the sample years are moderate, in the range 0.81 to 0.93. Average productivity progress across the sample years has been 26 percent. The results illustrate the usefulness of DEA even when there are no inputs and the decomposable Malmquist index for productivity is an asset in exploring causes of productivity growth. |
