Agglomeration externalities and technical efficiency in French pig production Inra
Larue, S.; Latruffe, L.; INRA, Institut National de la Recherche Agronomique (FRA).
L’objectif est d’évaluer les effets de l’agglomération spatiale sur l’efficacité technique des exploitations porcines françaises. Nous utilisons une approche en deux étapes. Dans la première étape, nous calculons les scores d’efficacité de l’activité porcine avec la méthode non-paramétrique “Data Envelopment Analysis” (DEA; Analyse d’Enveloppement des Données). La deuxième étape consiste en une régression de ces scores sur des variables d’agglomération. Les données utilisées sont celles de 936 producteurs porcins en 2004. Les résultats suggèrent que ces exploitations ont été autant affectées par des externalités positives d’agglomération (provenant de la diffusion des connaissances facilitée par la densité d’exploitations, ou de la proximité des...

Agglomeration externalities and technical efficiency in pig production Inra
Larue, S.; Latruffe, L.; Université de La Réunion (REU); EAAE, European Association of Agricultural Economists (NLD); ERSA, European Regional Science Association (AUT).
The objective of the paper is to assess the effects of agglomeration on technical efficiency of French pig farms. The increasing concentration of pig production in western France is a typical example of how agglomeration externalities may have positive effects on farm performance in particular. However, negative externalities implied by concentration have lately appeared. They are due to increasing competition for land following the introduction of a law governing polluting activities according to which pig producers need to have a minimum area available where their manure can be spread. We use a two-stage method, where the first stage consists in calculating pig activity's efficiency scores with the non-parametric method Data Envelopment Analysis (DEA),...

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...

Converting to organic farming in France: is there an adverse selection problem? Inra
Latruffe, L.; Nauges, C.; EAAE, European Association of Agricultural Economists (NLD).
Several papers have investigated the determinants of conversion to organic farming, and pointed out the positive role of public support on the decision to convert. In this paper we investigate whether the conversion subsidy schemes may attract ‘subsidy-hunters’ who are not, in general, the most efficient farmers. Using panel data we test this adverse selection problem on a sample of French farms for the period 1999-2006, by measuring the impact of past technical efficiency on the decision to convert to organic farming. In the first stage we compute farmers’ yearly efficiency scores using several competing approaches in order to derive robust conclusions, including non-parametric techniques (Data Envelopment Analysis, Free Disposal Hull) as well as the...

Could small dairy farms in Switzerland compete with their French counterparts? A metafrontier analysis during 1990-2004 Inra
Ferjani, A.; Latruffe, L.; INRA, Institut National de la Recherche Agronomique (FRA); EAAE, European Association of Agricultural Economists (NLD); IAAE, International Association of Agricultural Economists (USA).
The objective of the paper is to investigate whether Swiss farms specialised in dairy (the prevailing production of the country), which are small in international standards, would have a survival potential if they had to compete more directly with EU farms. More specifically, we investigate whether Swiss dairy farms would be able to compete with their French counterparts (located in mountainous areas, but larger than Swiss ones) in a future made of increased globalisation and reduced borders. For this we evaluate which country, during the period 1990-2004, would have been more able to use efficiently a common hypothetical technology, and would have had a more productive (own) technology. Efficiency scores and technology ratios are calculated using the...

Determinants of technical efficiency of Slovenian farms Inra
Bojnec, S.; Latruffe, L.; EAAE, European Association of Agricultural Economists (NLD).
We investigate the determinants of technical efficiency of Slovenian farms employing the parametric stochastic frontier and non-parametric Data Envelopment Analysis (DEA) methods. The inherited initial inefficiencies of Slovenian family farms are confirmed by their relatively low technical efficiency. During the analysed period 1994-2003 the degree of technical efficiency has increased from around 0.5 to almost 0.8. Farm specialisation associated with technological change is found to be a crucial determinant for increasing technical efficiency. The negative impact of farm commercialisation on technical efficiency is explained by a specific nature of livestock farms, in particular, with intra-farm intermediary consumption. The use of hired labour has no...

Efficiency and environmental pressures of farrow-to-finish and finishing pig farms in Hungary Inra
Latruffe, L.; Desjeux, Y.; Fogarasi, J.; Bakucs, L.Z.; Ferto, I.; EAAE, European Association of Agricultural Economists (NLD).
Pig farming is one of the strongest polluters of water resources due to its intensive production techniques and slurry rejection. Several European countries have already introduced environmental regulations aiming at reducing the pollution caused by nitrates from agricultural sources, but not yet Hungary. This paper investigates how Hungarian pig farms would be affected if such regulations are to be enforced. We calculate farm technical efficiency separately for two types of pig production systems – namely farrowing only and farrow-to-finish farms (FAFI farms) and finishing only farms (FI farms) – using 2001 data on pig activity and Data Envelopment Analysis (DEA). We then investigate whether environmental regulations would affect the farms’ technical...

Farm performance and support in Central and Western Europe: a comparison of Hungary and France Inra
Fogarasi, J.; Latruffe, L.; INRA, Institut National de la Recherche Agronomique (FRA).
Nous analysons ici les différences en termes d’efficacité technique, d’évolution de la productivité, et de retard de technologie, entre les exploitations agricoles françaises et hongroises laitières et spécialisées en céréales et oléoprotéagineux (COP), sur la période 2001-2004. Nous utilisons des données des RICA nationaux et la méthode d’analyse d’enveloppement des données (Data Envelopment Analysis, DEA) sous l’hypothèse de frontières d’efficacité séparées selon les pays et sous l’hypothèse d’une frontière commune aux deux pays (métafrontière). Nos résultats indiquent que dans les deux secteurs étudiés (lait et COP), la technologie des exploitations hongroises la plus productive, malgré une absence de progrès technique. Il semble donc que les systèmes...

Farm performance and support in Central and Western Europe: a comparison of Hungary and France Inra
Fogarasi, J.; Latruffe, L.; AES, Agricultural Economics Society (GBR).
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....

Farm technical efficiency in pre- and post-accession Slovenia: the importance of size and subsidies Inra
Bojnec, S.; Latruffe, L.; IAMO, Leibniz Institute of Agricultural Development in Central and Eastern Europe (DEU).
In this paper we investigate Slovenian (individual) farms’ technical efficiency, and in particular its determinants, pre- and post-accession. As a background, we present the evolution of the farming structures and the agricultural policy in both periods. The pre-accession efficiency analysis is based on the few existing studies, while we present new results for the post-accession period. To our knowledge, no studies about farm performance exist for post-accession Central and Eastern European countries. In addition to the contribution to this part of research, our study sheds light on the links between farms’ efficiency, farms’ size and public support provided to farms, in Slovenia, in order to draw some insights into why the farming structures are still so...

How did Hungarian crop farms perform before accession: a comparison of technical efficiency and technology with France Inra
Fogarasi, J.; Latruffe, L.; CES, Chinese Economist Society (USA).
The paper investigates the difference in technical efficiency, productivity and technology between French and Hungarian cereal, oilseed and porteinseed (COP) darms during 2001-2004, using Data Envelopment Analysis with separate and common frontiers. Results indicate that Hungarian farmers showed lower scale efficiency and worse management practices than French farming on average. By contrast, under a common hypothetical technology, Hungarian farms would be by far the leaders, probably due to their scale economies and to their low use of variable inputs. This leadership might however not be sustainable as the Hungarian sample recorded technological regress, more and more substantial over the period. The EU subsidies that Hungarian farmers receive since...

Impact of CAP direct payments on French farms’ managerial efficiency Inra
Latruffe, L.; Guyomard, H.; Le Mouel, C.; EAAE, European Association of Agricultural Economists (NLD).
This paper investigates the relationship between CAP direct payments and managerial efficiency for French crop and beef farms. Managerial efficiency scores are calculated using a four-step approach that allows disentangling managerial inefficiency from other technical inefficiency components, notably what is due to unfavourable environment conditions. Then managerial efficiency scores are regressed over a set of explanatory variables, including CAP direct payments. Our empirical application, based on individual farm data and meteorological data at the municipality level for the year 2000, shows that there is a substantial component of inefficiency that is due to unfavourable conditions. Moreover, there is a significant negative relationship between...

This indicates that French crop farms that are more supported are less...

Impact of public subsidies on farms’ technical efficiency in New Member States before and after EU accession Inra
Latruffe, L.; Bakucs, L.; Bojnec, S.; Ferto, I.; Fogarasi, J.; Gavrilescu, C.; Jelinek, L.; Luca, L.; Medonos, T.; Toma, C.; EAAE, European Association of Agricultural Economists (NLD).
This paper presents some results of a twoyear (2006-2007) research project supported by the French Ministry of Research’s funding program ECONET. One of the project’s objectives was to investigate the determinants of farm technical efficiency in New Member States before and after accession to the European Union, and in particular the role of public subsidies on this performance variable. Four countries were considered: Hungary, the Czech Republic and Slovenia, who acceded to the EU in 2004, and Romania, whose accession was in 2007. The study found that subsidies had a negative impact on farm technical efficiency in Hungary over the period 2001-2005, in the Czech dairy corporate sector over the period 2000-2004, in Slovenia over the period 1994-2003, and in...

Performance of different institutional units in the Czech Republic and the role of external financing Inra
Davidova, S.; Latruffe, L.; Ratinger, T.; EAAE, European Association of Agricultural Economists (NLD).
The paper analyses the relationship between the financial structure of the different institutional units in the Czech Republic and their performance, by testing several theoretical hypotheses. It employs Data Envelopment Analysis to estimate separately corporate and individual farms’ technical efficiency, and investigates the effect of indebtedness on efficiency in a second stage, accounting for potential endogeneity. No substantial differences were detected between individual and corporate farms. For both groups higher long-term indebtedness negatively affects farm performance (agency theory and adjustment hypothesis), while the latter is used for appraising loan applications (credit evaluation). Case studies to banks and farms confirmed these findings.

Technical efficiency and productivity change of dairy farms: a comparison of France and Hungary Inra
Fogarasi, J.; Latruffe, L.; EAAE, European Association of Agricultural Economists (NLD).
The paper investigates the difference in technical efficiency, productivity and technology between French and Hungarian dairy farms during 2001-2004, using Data Envelopment Analysis with separate and a common frontier. Results indicate that Hungarian farmers are more clustered to their own frontier than French farms are, but are as scale efficient. Both samples have a slight technological progress over the period. Comparing the technology of both countries reveals that Hungarian farms have a superior technology. Under a common hypothetical technology, Hungarian farms would be the leaders but it seems that this leadership is reduced in 2004, raising question on the adequacy of the EU agricultural policy for large-scale dairy farming.

Technical efficiency and technology in Eastern and Western agriculture: a comparison of crop and dairy farms in Hungary and France Inra
Fogarasi, J.; Latruffe, L.; IAAE, International Association of Agricultural Economists (USA); EAAE, European Association of Agricultural Economists (NLD); CUB, Corvinus University of Budapest (HUN).
The paper investigates the difference in technical efficiency and technology between French and Hungarian farms in dairy and cereal, oilseed and protein seed (COP) sectors during 2001-2004. The analyses is performed with Data Envelopment Analysis (DEA) under separate and common frontiers. Results indicate that Hungarian dairy farmers are more clustered to their own frontier than French farms are, but that the difference is less clear in COP farming. Hungarian dairy and COP farms are less scale efficient than French farms on average. Under a common hypothetical technology, Hungarian farms would be the leaders. Reasons might be the presence of large corporate farms and a higher public support in Hungary.

Technical efficiency of Hungarian farms before and after accession Inra
Bakucs, L.Z.; Latruffe, L.; Ferto, I.; Fogarasi, J.; Hungarian Academy of Sciences, Institute of Economics (HUN).
In this study, both parametric (SFA) and non-parametric (DEA) efficiency approaches were used to analyse the technical efficiency (TE) of Hungarian farms before and after the accession. Slightly different results were obtained with SFA and DEA. After years of decreasing technical efficiency scores, accession seems to have halted the process and positively influence the evolution of average technical efficiency. A number of determinants of TE provide a plausible explanation of the evolution of efficiency.
