The objective of the paper is to develop a methodology for supporting the evaluation and design of agri-environmental schemes. The methodology is based on a combination of mathematical programming, contract theory and multicriteria analysis and is tested on a case study in Northern Italy. The methodology proposed can add insights into the policy design process, by taking consistently into account three issues often overlooked: the adaptation of cropping systems to the measures proposed; the diversity of compliance costs among farmers; the multidimensionality of the decision problem.

In the paper, a dynamic model of diffusion of genetically modified crop technology is developed and simulated using the U.S. soybean market data. The model accounts for factors specific to agricultural markets, such as oligopsony power and strategic interaction among crop processors, growers’ characteristics such as adoption behavior, and identity preservation requirements. Simulation results show how these factors affect the magnitude and distribution of the potential gains from genetically modified crops.

For decades the CAP has been the major influence in shaping EU agriculture and food production. The economic and policy environment in the EU is now very different from that which prevailed in the earlier decades. The future economic, social and geographic diversity of the EU will be further increased by enlargement. Agricultural policies and the related operational frameworks will inevitably change to accommodate this added diversity and the changing societal and consumer values. This paper evaluates how the current shape of EU agriculture has been influenced by the reforms to date. It also attempts to focus on where EU farming may be, or wish to go, over the next decade. The evaluation is restricted to the beef sector as it has been to the forefront in the policy reforms of the last decade and because the adjustments were inevitably complex due to the scale of the oversupply problems, the biological and market intricacies involved.

This evaluation concluded that the current EU beef policy is severely constrained with poor targeting of the income supports, high production costs, based on an administratively complex and expensive control system without any clear benefit to either society or taxpayer for a rather large expenditure. In the past, agricultural policy in the EU was primarily driven by the need for a secure food supply and with the objective of sustaining the economic and social needs of farmers. But, in the well fed and affluent EU society of the 21 st century, agricultural policy will be mainly driven by the economic and social goals which are rapidly changing. This society places a declining value on extra units of food production, but an increasing value on any public goods consumed in the production process. As a consequence, the mix of agricultural production and public goods that this society is prepared to support financially is changing rapidly. The level and components of farm incomes in the EU in the 21 st century will reflect these changes. Farm revenue will likely consist of a mix of payments for conventional agricultural products and public goods. The public good payments will be conditional on the level and type of inputs used, farming practices, types of products produced and a societal vision of the role of farming. This will affect production costs, scale of operation and the future configuration of agriculture and rural society. To meet this evolving situation the paper also develops and outlines a multi-commodity framework by which the EU could reorient its direct payment (DP) system to incorporate a range of public good values to the mutual benefit of consumers, taxpayers and farmers.

Water sharing has become a serious problem in France. One of the objectives of 1992 and 2000 directives proposed by the European Union was to reduce both the frequency and the extent of water conflicts through the establishment of multilateral negotiations, where different public and private interests can be represented in a structured institutional environment. In France, many negotiations take place at local level between farmers, water suppliers, public services and environmentalists to allocate water resources between users. We suggest that Agent–Based Modelling (ABM) using a multi-agent approach could help negotiations between different players by showing the consequences of water allocation rules and taking in consideration the players’ respective attitudes and their ability to change their behaviour.

Based on the Policy Analysis Matrix (PAM) approach this paper provides an assessment of the competitive position of the Hungarian agro-food industry in view of EU integration. The situation in the food processing sector is assessed with the use of actual cost data from representative Hungarian companies. The paper presents an assessment of the current situation prior to EU integration as well as a future outlook under various scenarios with regard to the expected policy environment and the rate of technological change. The actual measurement of competitiveness in this study focuses mainly on Private Resource Cost (PRC) which indicates competitiveness under real market conditions and Domestic Resource Cost (DRC) which gives an assessment on the social or economic efficiency of an activity, i.e. whether domestic resources are really used efficiently in current production. In the food processing sector 21 different food products have been investigated which fall into four industries: meat, poultry, dairy, and fruits and vegetables. Under current conditions only some products are competitive in private terms. The situation would improve after EU integration especially for poultry, fruits and vegetables, because agricultural policy conditions are more favourable under the CAP. If additional FDI(Foreign Direct Investments) would flow into the country after EU membership, this would boost profitability. As far as DRC values are concerned, it must be stated that only some of the production activities are clearly efficient. Dairy, fruits and vegetables, and roast goose production show relatively weak social competitiveness, while other poultry and fruit and vegetables products are more favourable from the economic point of view. As EU policies provide on average higher protection levels, the competitiveness of Hungarian food processing on world markets would deteriorate for most products after EU accession. However, these effects can be offset by additional technological change due to FDI inflows or otherwise induced technological progress.

The strategies for exploiting typical production represents a theme of great interest, above all in the measure in which exploitation brought about via adequate marketing strategies allows these products to shed their anonymity. This paper constitutes a contribution in this direction, since it analyses the potential of a traditional product ('Nduja) using multivariate analysis techniques on a sample of consumers, identified by a specific market research survey. This made it possible to define the main characteristics of the type of consumer of this product and to define suitable market segmentation strategies.

Participatory approaches in natural resource management are increasingly being criticized for their tendency to neglect power relations and conflicts of interests. Negotiation approaches have been proposed as a strategy to overcome such shortcomings. The increasing practical relevance of negotiation in natural resource management requires the development of theoretical concepts for analyzing the nature and outcome of such negotiation processes. Using the case of negotiations concerning crop-livestock conflicts in Sri Lanka as an empirical example, this paper applies the concept of political capital in combination with game theoretical modeling for an analysis of negotiation processes in natural resource management. An extended form game is used to examine the incentive structure of the resource users and the political decision-makers involved in the negotiation process. The pay-off of the resource users is measured in economic terms, while the pay-off of the political decision-makers is expressed in terms of political capital. The modeling exercise shows how the incentives of the resource users and the politicians depend on the probability that the public administration enforces a negotiated outcome. The paper discusses potential extensions of the model and concludes that the concept of political capital, in combination with game theoretical modeling, provides a useful tool for the analysis of negotiation approaches in natural resource management.

This paper is aiming at an analysis of Rural Development Programs (RDP) in Turkey with special reference to EU Rural Development Policies, Programs and implementations. Concerning to Turkish Programs, it has been reported that over the last 30 years and more particularly during the planned Development Period, special efforts have been made to gain Rural development experience in Turkey. In each five year Development Planning period (DPP), particular goals and instruments of policy for both agricultural development and that of rural areas have been specified and determined. Integrated Rural development Projects and some other typical Rural Development Projects have also been implemented in line with the targets given in each planning period.

This paper analyses the impact of the dairy quota scheme on the size distribution of the Dutch dairy industry. A non-stationary Markov model approach is used, where the transition probabilities are explained by a set of exogenous (policy) variables. Using an information theoretical approach, a model is estimated for The Netherlands and used to simulate the impacts of alternative EU dairy policies. Several results emerged:
a) There is an autonomous over time decline in farm numbers (implying increase in farm size).
b) The dairy quota regime positively influences 'small' and 'medium' farm sizes;
c) Abolition of the dairy quota will negatively affect the total number of active farms and favours further increase of farm scale.
d) Targeting support according to needs increases the number of active dairy farms as compared with the status quo.

This paper proposes an Economic Drought Management Index (EDMI) that could assist water managers to inter-temporally manage water reservoirs. The index’s main appeal is that it can be easily interpreted and that encompasses in a single number hydrological processes, structural constraints, water institutions’ rules and the economic benefits of the customers served from the supply system. An empirical application of EDMIs is performed for two irrigation districts in Andalusia (Southern Spain), that are managed under different institutional arrangements. Results for one district show that the region’s vulnerability to drought could be reduced following the interpretation of the EDMIs. For the other district, the index shows that water stocks are managed under nearly optimal criteria. This last result shows that there is an efficient level of drought vulnerability, and that increasing supply security levels would result in welfare losses.

Under the TRIPs Agreement, all member-countries of the World Trade Organization are required to provide an "effective" system of plant variety protection within a specific time frame. In many developing countries this has led to a divisive debate about the fundamental desirability of extending intellectual property rights to agriculture. But empirical studies on the economic impacts of PVP, especially its ability to generate large private sector investments in plant breeding and facilitate the transfer of technology, have been very limited.

This paper examines two aspects of the international experience of PVP legislation thus far (i) The relationship between legislation, R&D expenditures and PVP grants, i.e., the innovation effect, and (ii) The role of PVP in facilitating the flow of varieties across countries, i.e., the transferability effect.

An experimental store was created to evaluate initial demand for locally-produced and guaranteed tender steak products as a more realistic alternative to contingent valuation (CV) and dichotomous-choice experimental methods. Strengths of the approach are incentive compatibility, a realistic consumption set, and a familiar choice environment. Consumers selected among USDA Choice, premium quality, lean, guaranteed tender, and locally-produced strip steaks. Double-hurdle count data model indicated initial willingness-topay for locally-produced steak comparable to prior CV results, but demand was highly elastic. Demand for premium quality steak crowded out demand for the guaranteed tender product, contrasting with prior dichotomous-choice experimental results.

Many development projects seek to reach the poorest in the provision of agricultural inputs, extension, credit, education, and many other services. However, low-cost and reliable methods for assessing whether a project reaches the poor are lacking at present.

In this paper, we present an operational method that was designed during a two-year research project from 1999-2001 with the support of an international donor- coordination office. The objective of the research was to develop and test a new method that could be later used by development practitioners to assess the poverty level of beneficiaries of development projects that target the poor in relation to the general population in the intervention area. The method constructs a poverty index using principle component analysis, and is based on a range of indicators that describes different dimensions of poverty and for which credible information can be quickly and inexpensively obtained. To ensure the method’s usefulness to a wide number of countries and projects, the method was tested in collaboration in rural and urban areas in four countries: Nicaragua (urban and rural), Kenya (urban and rural), Madagascar (rural), and India (rural). We present results from these studies. We conclude that the method has a promising potential for monitoring and evaluation purposes of development organizations. Since 2001, the method has been used in over 20 project assessments.

The regulation for the promotion of rural areas (Reg. (EC) No 1257/1999) and its subsequent regulation (Reg. (EC) No 1853/2003) serve as the basis for EU agricultural structural policy for the promotional period 2000 to 2006. Promotional areas established through the individual regulations such as agricultural development measures, measures to improve competitiveness and the previously accompanying measures of the agricultural reform in 1992, as well as compensatory allowences for disadvantaged areas, are initially consolidated in these two regulations. The Commission’s overall intention is to adjust the promotional areas in terms of time and content and thus to target promotional synergy. A further change in the promotional approach is that the nine promotional areas of the regulation are to be evaluated by independent evaluators according to a Commission designed European-wide evaluation grid (European Commission, 2000). The processing of the common evaluation questions is obligatory, should a question or part of the questionnaire not be answered, an explanation must be included (ibid., P. A-3). The Commission reserves the right to stop EU co-financing should the evaluation not meet its criteria. This paper places a focus on critical reflection about the evaluation grid required by the Commission with regard to its use in the evaluation process using the example of agri-environmental measures.

In this paper we present a partial equilibrium model for the bovine sector (beef and dairy) in Italy, which can be used for simulation and forecasting. The structure of the model follows the vertical chain of the beef and dairy sector, allowing trade of both agricultural raw materials and final products. Since the processing and retailing stage is characterised by an imperfectly competitive structure, the model accounts for market power in modeling the price transmission mechanism. This provides further insights on the vertical transmission of shocks, both at the final level (i.e. the BSE crisis) and at the farm level (i.e. agricultural policy reform).
