A Bayesian Total Factor Productivity Analysis of Tropical Agricultural Systems in Central-Western Africa And South-East Asia AgEcon
Tonini, Axel; Matus, Silvia Saravia; Gomez y Paloma, Sergio.
This paper computes and analyses total factor productivity (TFP) growth rates for tropical agricultural systems in Central-Western Africa and South-East Asia. Two regions that despite sharing common agro-ecological conditions, have pursued different adoption rates of green revolution technology and have reported dissimilar yields per hectare. A panel data set is constructed for the period 1987-2007 from the FAOSTAT database. A Bayesian stochastic frontier model with country specific temporal variation in technical efficiency is estimated. Technical efficiency estimates reveal that there is substantial room for improvement in both continental sub-sets and that TFP estimates show on average larger rates of growth for South-East Asian countries as compared to...

Over fifteen years have elapsed since the transition from the centrally planned economic system started in the early 1990’s. During this time agricultural and rural areas of Central and Eastern Europe have undergone profound structural changes with wide variations in the degree of transformation and in the rate of success in creating a competitive market and private ownership based food and agricultural system. By becoming member of the European Union the "transition" in its traditional interpretation has been concluded in ten of the Central East European countries. The transition to market based agriculture, however, is far from completion in Southern and Eastern Europe and especially in the CIS countries. International Association of Agricultural...

Assessing the impact of future CAP reforms on the demand of production factors AgEcon
Bartolini, Fabio; Viaggi, Davide; Ronchi, Davide; Gomez y Paloma, Sergio; Sammeth, Frank.
The CAP reform process has been a central issue for agricultural economics research in recent years, and is gaining further attention in view of the post-2013 perspectives. The objective of this paper is to assess ex-ante the effect of different post-2013 CAP and market scenarios on the demand of productions factors. The paper is based on the use of farm household dynamic programming models maximising the net present value with a time horizon until 2030. A representative model has been implemented for 18 different farming systems in 8 EU countries. Changes in marginal values of selected resource constraints (land, labour and capital) are used to assess the potential effect of different scenarios on farm-household demand of production factors. Results...

Between markets and policy: farm household's reaction to decoupling AgEcon
Gomez y Paloma, Sergio; Raggi, Meri; Viaggi, Davide.
The main objective of this paper is to evaluate ex post the effects of 2003 decoupling, with a specific focus on farm investment behaviour. In the past years a number of studies have addressed the issue of the impact of EU policy reforms. However, long term effects of policy changes and related impacts on structural and investment behaviour received relatively little attention in modelling exercises concerning CAP reform up to now. This study is based on a survey about 250 farm households in Italy, Germany, Poland, Spain, Greece, The Netherlands, France and Hungary. In the majority of cases, farmers stated they were indifferent to decoupling. Where any change occurred, the impact of decoupling was highly differentiated. Differences in reaction are better...

Distributional Effects of CAP Subsidies: Micro Evidence from the EU AgEcon
Michalek, Jerzy; Ciaian, Pavel; Kancs, d'Artis; Gomez y Paloma, Sergio.
In this paper we estimate the income distributional effects of the common agricultural policy (CAP) for farmers and landowners. First, we theoretically analyse the level of farmers' and landowners' gains from coupled and decoupled payments. Second, using a unique farm level panel data set from the FADN for the period 1995-2007 we employ the fixed effects, the Heckman selection bias and the GMM estimators to estimate income distributional effects of CAP subsidies. The results do not confirm the theoretical hypothesis that landowners benefit a large share of the CAP subsidies. According to our estimates, farmers gain between 60% to 95%, 80% to 178% and 86% to 90% of the total value of coupled crop/animal, coupled RDP and decupled payments, respectively. The...

The CAP subsidies are only marginally capitalised in land rents. Our results suggest that rental rates are more responsive to...

EU-wide Distributional Effects of EU Direct Payments Harmonization analyzed with CAPRI AgEcon
Gocht, Alexander; Britz, Wolfgang; Ciaian, Pavel; Gomez y Paloma, Sergio.
We argue in this paper that available econometric estimates of farmers’ risk aversion do not measure true farmers’ preferences towards risky outcomes. Available analyses are mostly of static nature and indeed measure the parameters of the synthetic optimal value function rather than the deep parameters of the utility functions. We derive analytical and empirical results in a simple dynamic and stochastic framework showing that that there is not a simple relationship between utility functions and value functions when agents have many decision variables. In particular we find that the value function does not necessarily exhibit DARA when the instantaneous utility function satisfies DARA and conversely. We recommend performing dynamic econometric estimation...

Facing decoupling: use of payments and investment reaction to decoupling in the EU AgEcon
Viaggi, Davide; Raggi, Meri; Gomez y Paloma, Sergio.
The main objective of this paper is to evaluate ex-post the effects of the 2003 reform, in particular decoupling, of the Common Agricultural Policy (CAP) in the European Union (EU), with a specific focus on farm investment behaviour. In the past years a number of studies have addressed the issue of the impact of EU policy reforms. However, long-term effects of policy changes and related impacts on structural and investment behaviour received relatively little attention. This study is based on a survey of farm households in a number of EU Member States. In the majority of cases, farmers stated they were indifferent to decoupling. Where any change occurred, the impact of decoupling was highly differentiated. Numerous reactions are better explained by various...

Facing the future: strategies and investment behaviour of polish farmers AgEcon
Gomez y Paloma, Sergio; Majewski, Edward; Raggi, Meri; Viaggi, Davide.
This paper analyses farm-household strategies and investment behaviour of Polish farmers with a particular focus on the perceived effects of CAP. The paper is based on a survey of Polish farmers carried out in 2006 on a sample of 63 farms. Farmers where selected in order to fit in the intersection of the following categories: different altitudes (plain/mountain); different specialisation (arable crops, livestock, fruit trees), different technology (conventional, organic). The survey includes information about farm and household structure, expectations, reaction to planned and intended investment, as well as about potential reforms such as decoupling of EU payments. Results show multifaceted expectations toward the future. The main objectives expressed by...

Impact of rural poverty reduction strategies: The case of smallholders in Sierra Leone AgEcon
Sammeth, Frank; Lakoh, Alpha; Michel, Baudouin; Hites, Gisele; Gomez y Paloma, Sergio.
The present analysis, which exploits one of the first empirical data collected from smallholders in Sierra Leone since the end of the civil war, compares the impact of two poverty reduction strategies targeting smallholders in Sierra Leone: support to rice production is compared with support to coffee and cocoa production in terms of sustainable income generation and contributing to macroeconomic stability and growth. Supporting rice production is intended to help the country regain self-sufficiency in its traditional principle staple. This will help towards improving food security and reducing dependency on volatile world market prices which, for example, with respect to the recent global spike has had dramatic effects on the lowest incomes. Support to...

MODELLING THE EFFECT OF EU POLICY REFORMS ON FARM INVESTMENT BEHAVIOUR AgEcon
Gallerani, Vittorio; Gomez y Paloma, Sergio; Raggi, Meri; Viaggi, Davide.
The objective of this paper is to analyse farm strategies and investment behaviour in a sample of selected Italian farm-households facing different scenarios, with a particular focus on the effects of the 2003 CAP reform. Models were built for individual households using multi-criteria dynamic programming, including investment choice. A total of 24 farms were selected for modelling, all located in Emilia Romagna (Italy). The simulations show a strong effect of both policy and markets scenarios on household investment, though the latter seems more relevant than the former. However, decoupling itself shows minor effects in the majority of cases. The models offer useful insights about the mechanisms of adaptation and their implications for the effects of...

Semi-subsistence farm households and the non-farm rural economy - Perspectives and challenges AgEcon
Buchenrieder, Gertrud; Fritzsch, Jana; Wegener, Stefan; Curtiss, Jarmila; Gomez y Paloma, Sergio.
Semi-subsistence farm households (SFHs) have persevered in Central and Southeastern Europe. An outlook on future perspectives of SFHs asks for reliable information on the phenomenon of SFHs and the impact of policy measures on their development options: (1) intensifying farming, (2) diversifying income creating activities, or (3) exiting farming for waged employment. This article focuses on SFHs and rural non-farm employment (RNFE). On the basis of a comparative 2007-survey of 489 SFHs in Bulgaria, Poland and Romania, three countries with particularly many SFHs, four major types of SFHs (rural pensioners, farmers, rural diversifiers, rural newcomers) were identified. For policy analysis, a multiobjective linear programming household model was developed. In...

Semi-subsistence Farm Households in Central and South-eastern Europe: Current State and Future Perspectives AgEcon
Fritzsch, Jana; Wegener, Stefan; Buchenrieder, Gertrud; Curtiss, Jarmila; Gomez y Paloma, Sergio.
The European Union (EU) introduced a special transitional semi-subsistence measure to promote the smallest agricultural producers, so-called semi-subsistence farm households (SFHs) in the enlargement process. An outlook on the future of SFHs requires comprehensive and reliable information on the phenomenon and the impact of policy measures on their development. Therefore, a survey using a standardised questionnaire was conducted in Poland (175 households), Romania (185 households), and Bulgaria (184 households) from July to September 2007. In a first step, four major types of SFHs could be identified by means of cluster analysis: (i) rural diversifiers, (ii) rural pensioners, (iii) farmers, and (iv) rural newcomers. In a second step, a multiobjective...

The Value of EU Agricultural Landscape AgEcon
Pavel, Ciaian; Gomez y Paloma, Sergio.
The present paper provides a meta-analysis of agricultural landscape valuation studies and through the estimated benefit transfer function it projects the value of EU landscape. The analyses are based on information from more than thirty European and Non-European studies which use stated preference approach to uncover the society's willingness to pay (WTP) for landscape. Our calculations show that, the per hectare WTP in EU varies between 89 and 169 €/ha with an average value of 142 €/ha in 2009. Further the calculations indicate that the total value of EU landscape in 2009 is estimated to be in the range of €16.1 – 30.8 billion per year, with an average of €25.8 billion, representing around 7.5 percent of the total value of EU agricultural production and...

UNDERSTANDING THE DETERMINANTS OF INVESTMENT REACTIONS TO DECOUPLING AgEcon
Gallerani, Vittorio; Gomez y Paloma, Sergio; Raggi, Meri; Viaggi, Davide.
The objective of this paper is identify the determinants of reaction to decoupling, focusing, in particular, on farm strategies and investment behaviour both on-farm and off-farm investment. The paper analyses a sample of 248 farm-households located in 8 EU countries, using decision tree algorithms. The factors emerging as determinants of an increase of on-farm investment as a reaction to decoupling are the existence of a successor, age, farm size, part time vs. full time head of farm. Allowing for the use of country variables, these tend to account already for the factors listed above and become the main predictors, followed by labour endowment, specialisation and expectations.
