Agricultural policy support and technical efficiency in French agriculture Inra
Desjeux, Y.; Latruffe, L.; iDEAs, International Data Envelopment Analysis Society (USA).
This paper investigates how the various changes in the policy supporting agriculture in the European Union, the Common Agricultural Policy (CAP) and various types of subsidies, have affected farms’ technical efficiency in France between 1990 and 2006. Several efficiency scores are computed: using the Free Disposal Hull (FDH) method; using Data Envelopment Analysis (DEA) under constant (CRS) and variable returns to scale (VRS); scale efficiency scores calculated with DEA; and DEA technical efficiency scores corrected for bias both under CRS and VRS with the bootstrap method. We consider four periods: 1) 1990-1994 is the benchmark period; 2) 1995-1999 is the period where the effect of the first CAP reform is investigated 3) 2000-2005 represents the period...

Efficiency and environmental pressures of farrow-to-finish and finishing pig farms in Hungary Inra
Latruffe, L.; Desjeux, Y.; Fogarasi, J.; Bakucs, L.; Ferto, I.; iDEAs, International Data Envelopment Analysis Society (USA).
Pig farming is one of the strongest polluter of water resources in developed countries, due to its intensive production techniques and slurry rejection. Several countries have already introduced environmental regulations aiming at reducing nitrate and phosphorus waste from pig farming, but not yet Hungary. This paper aims at shedding light on how Hungarian pig farms would be affected if such regulations are to be introduced in the country. We calculate farm technical efficiency separately for farrowing only and farrow-to-finish farms (FAFI farms), and finishing only farms (FI farms), using farm data relating to pig activity in 2001 and Data Envelopment Analysis (DEA). We then investigate whether environmental regulations would affect Hungarian pig farms’...
