The goal of this paper is to estimate the maximum price consumers are willing to pay (MPWTP) for organic beef meat. To this purpose, a theoretical and econometric approach is presented, based on the RUM model and on a Contingent Valuation technique.

The results show that consumers’ MPWTP is quite high, thus suggesting that organic beef meat might gain an appreciable market share. This is also an encouraging signal for prospective producers of organic meat, who might compensate the likely increase in production costs with a substantial premium for the new good.

In this paper, models for estimating the maximum price consumers are willing to pay (MPWTP) for organic beef meat, and the maximum quantity-constrained price (i.e., when buying the same quantity they bought of regular meat) consumers are willing to pay (MQCP), are presented. To this purpose, the relevant theoretical and econometric approaches are presented, based on the RUM model and on a Contingent Valuation technique.

In this paper we survey the literature on asymmetric price transmission. This literature contains a substantial share of publications by agricultural economists. After classifying the different types of asymmetric price transmission in section 2, we describe the explanations for asymmetric price transmission that have been proposed in section 3. In section 4 we focus on the econometric techniques used to quantify asymmetry. Section 5 concludes with a discussion of outstanding methodological problems and suggestions for future research. Our main conclusion is that the existing literature is far from being unified or conclusive, and that a great deal of work remains to be done. A wide variety of often conflicting theories of and empirical tests for asymmetry co-exist in the literature. Furthermore, existing tests are not discerning in the sense that they as a rule to do not make it possible to choose between competing explanations for asymmetry on the basis of empirical results. Therefore, after more than three decades of work, a considerable need for further research remains, and it would appear premature to draw far reaching conclusions for theory and policy on the basis of work to date.

New crop varieties often have been promoted in developing countries based upon superior yield vis-a-vis locally available varieties. This research presents a hedonic model for upland rice by drawing upon the input characteristics and consumer good characteristics model literature. Model specification tests determine that a combination of production and consumption characteristics best explains the willingness to pay for new upland rice varieties. This non-separable household model specification determined that four traits explain the willingness to pay for new rice varieties: plant cycle length, plant height, grain elongation/swelling and tenderness. Yield was not a significant explanatory variable of the willingness to pay for seed. br>
The implications of this model are two-fold. First, varietal development and promotion must include post-harvest characteristics in addition to production traits when determining which varieties to promote for official release. Secondly, non- yield production characteristics such as plant height and cycle length are significant factors in producers_ assessments of the value of a new variety. Overall, this paper provides an alternative explanation for limited adoption of modern upland rice varieties in West Africa: varietal evaluation programs have focused too narrowly on yield evaluation and have not promoted varieties with superior non-yield characteristics than locally available varieties.

This article considers the impacts of (de)coupled farm sector support on the locations of farming and agro-industrial activity. An economic geography model is developed which has two types of regions, one with extensive agricultural production (rural), the other with intensive farming that is more densely populated (urban). The farm and agro-industrial sectors are vertically linked. A service sector that is not directly linked to either basic industry is also explicit. We show that coupled and decoupled subsidies affect the spatial distribution of farming, industry, and service sector activity. Support that is provided to all farmers regardless of crop, thus semi-decoupled, increases spatial agglomeration. Support targeted to farmers of particular crops, especially rural comparative advantage crops, favors increased farming in rural areas but spatial agglomeration of non-farm activity still occurs. This latter targeting approach is used in the European Union.

This paper aims at evaluating the impact of two different cash transfer programs in rural Mexico – Procampo and Progresa – on total consumption, food consumption and other outcomes like investment, schooling and health care. Progresa is targeted to women, while Procampo goes to farmers, mostly men and many of which are poor. We show that both programs boost consumption. However, they obtain this effect through different channels. Progresa is destined to consumption expenditure directly, while Procampo, which is paid to landholders, boosts investments and needs time to produce its benefits. Furthermore, we separate program from gender effects and show that cash transfer programs targeted to men are beneficial only when the recipients own means of production. This suggest that policy makers should take into account the relationship between gender and ownership of assets when designing poverty reduction programs.

Drawing from the interim findings of a 2 year, EU-wide project, this paper considers the contribution the CAP makes to territorial cohesion across Europe. It is based on analysis of indicators at NUTS 3 level for the EU 27 (including Switzerland and Norway) and initial findings from a case study of CAP support in a region of Austria. Analysis shows that the incidence of Pillar 1 support is not consistent with the economic or social cohesion objectives of the EU. In particular, statistical analysis suggests that Pillar 1 support is distributed in such a way that it tends to benefit richer regions with lower unemployment rates and with higher than average population growth. Contrary to expectations, the incidence of Pillar 2 support is also inconsistent with cohesion objectives, favouring the richer areas of the EU. Reasons identified for the pattern of Pillar 2 support include differing national priorities, the uneven allocation of RDR funds and difficulties of co-financing in poorer regions. Importantly, analysis of the impact of the Mid Term Review proposals on farm incomes suggests that the latest reforms of the CAP will not improve the consistency between the CAP and cohesion. The paper discusses the key policy implications arising from the findings. It is argued that although member states are increasingly able to direct discretionary support measures towards territorial priorities, this is still only a very minor part of the CAP. As is exemplified by the case study in Austria, only a substantial comprehensive effort of rural development measures can provide compensatory territorial effects. Finally, the need for a more coherent, integrative rural development policy framework is discussed.

This paper proposes a partial equilibrium displacement model that differentiates wheat according to its end-use and country of origin to investigate the impact of alternative European trade policies on wheat supply and demand in France. Transmission, demand and supply elasticities are estimated for each class and origin of wheat. Simulation results show that rebalancing trade protection across wheat classes encourages domestic supply of high quality wheat and displaces imports from North America.

Although there is broad agreement that well functioning land rental markets will play an important role to increase productivity and household welfare as agrarian economies develop, evidence from Africa on the actual performance and impact of such markets is limited. We use data from Uganda to test for differences in the performance of rental, as compared to sales markets and their evolution over time, based on a framework where markets are affected by differences in ability and imperfections in rural labor and capital markets.

We find that land markets are very active, that land rental but not sales markets transfer land to more efficient and relatively poor producers thereby providing an opportunity for the landless to access land, and that rental market activity has increased recently with economic growth. Despite land prices in some regions being above the net present value of land we find no evidence for sales markets leading to land concentration and conclude that, rather than imposing administrative restrictions, government should aim to improve access to alternative savings instruments.

Last decades have seen the development of a new rural policy. Different problems occurring in rural areas have pushed the EU Commission to draft policy instruments aiming to address them. However this rural policy path has not always been explicit neither has followed a continuous trend but rather has seen a series of forward and backward steps. Given the lack of a method to establish the relevance and the level of political acceptance of EU rural policy, a methodology has been developed. This methodology has tried to identify the EU political procedure trend, though this is not a formal sequence, and to establish a classification of different events according to a proposed hierarchy. Several EU documents, decisions, directives and financial resource allocations have been analysed. Within the review performed, each rural policy milestone has been classified following the proposed hierarchical chart. This has enabled the drawing of the different backs and forwards taken by this process. Besides, it has lead to the interpretation of the rural policy instruments current position in relation with other European policy instruments.

This paper proposes an analytical framework to examine the market and welfare impacts of GMOs, when some consumers refuse genetically modified organisms (GMOs) and when two supply channels are segregated (one for goods that containing GMOs and one for non-genetically-modified identity-preserved goods).

Our analytical framework begins at the level of individual farmers, handlers and consumers, to build up market supply and demand functions. This allows us to circumvent the difficulties of conducting supply and demand analysis in the different horizontally and vertically related markets concerned by GMOs and market segregation. We represent explicitly the costs of non-GMO segregation and identity preservation (IP) for both producers of non-GM IP goods and producers of non-IP goods, and how these costs vary depending on the relative sizes of the two production channels. We then illustrate our model by a simulation of potential adoption of GM rapeseed with non-GMO market segregation in the European Union (EU). We analyze how the costs of IP are distributed among heterogenous producers, handlers and consumers in this simulation.

In this paper, we conduct an empirical investigation of potential adoption of herbicide-tolerant (HT) genetically modified (GM) rapeseed in France. Our aim is to study ex ante the potential impact of their adoption in France, in terms of adoption level, economic gains, and distribution of these gains between farmers and input suppliers. We use French survey data about current plant protection practices, in order to compute pesticide costs with conventional (i.e., non GM) crops for individual farms. Then, based on results of technical studies about GM variety trials in France, we compute a predicted pesticide cost with the GM variety. Next, we study adoption rates and gains or losses of farmers (adopters and non adopters) and upstream companies (sellers of conventional herbicides, of the total herbicide to which GM rapeseed is tolerant, of GM seed), depending on the GM seed license price, the margin rate on herbicide sales and the price of conventional herbicides.

This paper presents a comparative method (SICOM) to evaluate complex site conditions at the level of a Federal State (Brandenburg) and at different areal units. The methodology uses primary site conditions and provides the possibility to objectively compare and judge different ecological questions. Objects with heterogeneous content are pooled in comparison groups. Consideration of the main site characteristics allows a goal-oriented allocation of subsidies. The use of SICOM is demonstrated for the wind and water erosion risk assessment across different scales from Federal State down to a parcel of land. The “parcel” aggregation-level proves to be useful to assess the erosion risk. Larger scales are less useful in the assessment of subsidies policy with regard to erosion risk. SICOM is demonstrated to be suitable for comparing and assessing regional aspects more objectively.

In this paper a study is presented that had as goal to develop a management instrument ( benchmarking)for co-innovation projects on basis of a set of performance indicators for chains and net-works of firms. To base the indicators on a sound basis relevant theories were studied, like industrial economics, resource-based theory, marketing theory, net-work theory and also specialised theories related to flexibility, innovation and quality care.

Thereafter a framework was developed. The framework consist of a quick scan of performance measurement and comparative benchmarking to get a global idea of the possible improvements. For the aspects that need to be improved a more fine tuned approach is the measurement of performance related tot the different processes and a benchmark thereof. In the fine tuned part of the framework we distinguish capacities, realisation and perspectives. The quick scan part is used to get a global idea of the performance of different apple chains in The Netherlands, France and New-Zealand. It appeared to be a useful approach to get an idea about the performance of different chains with help of desk research and published information. Finally, some conclusions are drawn.
