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...

Analyse des Phénomènes Spatiaux en Economie (FRA); NARSC, North American Regional Science Council (USA); GAPEM, Groupe d'Analyse de la Performance en Economie et Management (BEL); SFER, Société Française d'Economie Rurale (FRA).
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...

Another look at the distribution of direct payments: the link with part-time farming Inra
Latruffe, L.; Mann, S.; EAAE, European Association of Agricultural Economists (NLD).
Since the government supports the farming sector, the question about the distributional impact of this support bothers agricultural economists. However, studies on support distribution have not been concerned about the part-time characteristics of farms. Part-time farms, having other obligations but to produce intensively, might be disadvantaged in terms of public transfers. Our hypothesis is that a higher degree of decoupling enables part-time farms to capture more easily direct payments than full-time farms. To test this, we do not use the usual approach of comparing several hypothetical policies in the same group of farmers, but we compare two existing policies in different countries: the largely decoupled direct payment system in Switzerland where we...

Another look at the distribution of direct payments: the link with part-time farming Inra
Latruffe, L.; Mann, S.; INRA, Institut National de la Recherche Agronomique (FRA).
This paper contributes to the research about the relationship between off-farm employment and public support, by taking the issue upside down: does off-farm employment give an advantage to farms regarding the level of public support? Our hypothesis is that a higher degree of decoupling enables part-time farms to capture more easily direct payments than full-time farms. To test this, we compare the largely decoupled direct payment system in Switzerland in 2004, and the rather production-oriented payment system in France in 2003. Results show that Switzerland’s policy favoured farmers with an off-farm employment, while the French direct payment system had the opposite effect.

Application of a double bootstrap to investigation of determinants of technical efficiency of farms in Central Europe Inra
Latruffe, L.; Davidova, S.; Balcombe, K..
The paper provides one of the first applications of the double bootstrap procedure (Simar and Wilson 2007) in a two-stage estimation of the effect of environmental variables on non-parametric estimates of technical efficiency. This procedure enables consistent inference within models explaining efficiency scores, while simultaneously producing standard errors and confidence intervals for these efficiency scores. The application is to 88 livestock and 256 crop farms in the Czech Republic, split into individual and corporate.

L'article présente l'une des premières applications empiriques de la procédure de double bootstrap (Simar and Wilson, 2003) dans une estimation en deux étapes de l'influence de variables environnementales sur des scores non paramétriques d'efficacité technique. Cette procédure permet d'obtenir des estimations efficaces dans les régressions expliquant les scores d'efficacité, tout en produisant des écarts-type et des intervalles de confiance pour ces scores d'efficacité. La procédure est appliquée à des exploitations tchèques, séparées selon leur spécialisation de production (animale ou cultures) et selon leur forme légale (individuelle ou collective). Pour les deux spécialisations de production, les exploitations collectives présentent un score...

Assessing the impact of different rural development policy design options on the adoption of innovation across five case studies in the EU Inra
Bartolini, F.; Floridi, M.; Latruffe, L.; Majewski, E.; Nikolov, D.; Polman, N.; Viaggi, D..
Innovation and new technology adoption represent two central elements for the enterprise and industry development process in agriculture. The objective of the paper is to provide an ex-ante analysis of the effectiveness of alternative policy design options concerning the RDP measures intended to provide incentives for investment/innovation adoption in five case study areas across Europe. The model implemented is based on a real option approach that includes investment irreversibility and stochasticity in SFP. The results show the relevance of uncertainty in determining the timing of adoption and emphasise the importance of predictability as a major component of policy design.

Can the CAP payments facilitate the growth of individual farms in the NMS post-EU accession? Inra
Latruffe, L.; Davidova, S.; Douarin, E.; Gorton, M.; AES, Agricultural Economics Society (GBR); EAAE, European Association of Agricultural Economists (NLD).
The impact of the introduction of the EU Single Area Payments (SAP) on farm strategy is investigated for a sample of Lithuanian farms, utilising farm accounting and survey data. The applications of two investment models demonstrate that the credit market in Lithuania was imperfect prior to accession and that some farms were financially constrained. The introduction of the SAP has a significant, positive influence on farmers’ intentions to expand their farm area compared to a baseline scenario of the continuation of pre-accession policy. The switch in policy has a more pronounced effect on farms that were previously credit constrained. While the SAP has been presented as a policy support that is decoupled from production, its introduction will nevertheless...

CAP direct payments and distributional conflicts over rented land within corporate farms in the New Member States Inra
Latruffe, L.; Davidova, S.; IAAE, International Association of Agricultural Economists (USA).
This paper aims to investigate whether distributional issues within corporate farms in the New Member States will be exacerbated by the introduction of the CAP direct payments. The paper focuses on the specific impact of the payments on the land rented to the corporate farms by private landowners. If the latter are not satisfied with the level of rent they receive, they have the option to end their rental contract and withdraw their land from the farm. Before the accession to the EU the landowners did not have strong incentives to withdraw, as the other available opportunities were not associated with higher returns on land ownership. However, this situation might change as the landowners can now cash the direct payments themselves, providing they keep...

CAP direct payments and distributional conflicts within corporate farms in the New Member States: a game theory approach focusing on rented land Inra
Latruffe, L.; Davidova, S.; AES, Agricultural Economics Society (GBR).
This paper aims to investigate whether distributional issues within corporate farms in the New Member States will be exacerbated by the introduction of the Common Agricultural Policy (CAP) direct payments. The paper focuses on the specific impact of the direct payments on the rent negotiations between corporate farms and private landowners. If the latter are not satisfied with the level of rent they receive, they have the option to end their rental contract and withdraw their land from the farm. In this paper, game theory is used to model the negotiations between a corporate farm’s manager and a representative landowner. The model suggests that the CAP direct payments might induce more rent renegotiations, and that the latter will be successful and thus...

Capitalisation of government support in agricultural land prices in the Czech Republic Inra
Latruffe, L.; Doucha, T.; Le Mouël, C.; Medonos, T.; Voltr, V.; EAAE, European Association of Agricultural Economists (NLD).
The recent implementation of CAP area payments (the Single Area Payments, SAP) in the New Member States of the EU raises the question of whether a quick capitalisation of these payments is expected. Evidence of capitalisation of public support to agriculture into land prices indicates that benefits are partly transferred toward landowners rather than toward the targeted population (the producers). This distributional aspect is of particular importance in countries where a large proportion of land is farmed by producers who do not own this land, such as in the Czech Republic where corporate farms and large individual farms cultivate most of the agricultural area of the country, but rent more than 90% of it from millions of private landowners.This study...

Capitalisation of government support in agricultural land prices: what do we know? Inra
Latruffe, L.; Le Mouel, C.; INRA, Institut National de la Recherche Agronomique (FRA).
The objective of this article is to provide an overview of existing literature, both theoretically and empirically, on the extent to which agricultural subsidies do translate into higher land values and rents and finally benefit landowners instead of agricultural producers. Our review shows that agricultural support policy instruments contribute to increase the rental price of farmland, and that the extent of this increase closely depends on the level of the supply price elasticity of farmland relative to those of other factors/inputs on the one hand, and on the range of the possibilities of factor/input substitution in agricultural production on the other hand. The empirical literature shows that land prices and rents have a significant positive response...

Capitalisation of public support to agriculture into land prices indicates that the benefits are partly transferred toward landowners rather than toward producers. This distributional aspect is of particular importance in countries where a large proportion of land is farmed by producers who do not own this land. This study investigates the influence of several types of support on Czech agricultural land prices from private transactions between 1995–2001. The past period direct payments have been capitalised at the strongest rate, despite their low level and imperfections on the land...

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...
