Technical change versus efficiency change: how do food industries evolve over time?
Résumé
This paper adds to the rather scarce literature on the measurement of e ciency and productivity in the food-processing sector. Most of the existing studies on this sector have measured productivity applying parametric approaches to aggregate data.(...) In contrast with most of the previous literature our empirical analysis uses non-parametric approaches on a panel data of rms. The results of our study bring new evidence on the recent performance of one of the major manufacturing sectors in Europe. In Section 2 we discuss the role of production possibilities set in the measurement of technical change using panel data. We also present our proposed methodology, a simulation exercise describes basic intuitions. The application on French data is described in Section 3. Section 4 concludes
