The existence and the kind of asymmetry that characterize the relationships between shipping-point and retail prices are investigated for two major French fresh vegetables: tomatoes and chicory. Weekly data allow considering these relationships at very detailed levels such as region or supermarket chain. Moreover, the methodology proposes an implicit treatment of asymmetries in price transmission by using recently developed threshold cointegration methods. Our results do not give evidence to the widespread assertion that shipping-point price increases are completely and rapidly passed by middlemen on to consumers while there is a slower and less complete transmission of shipping-point price declines. As already emphasized in the literature, these results may be linked to the perishable nature of the two considered fresh vegetables.

This article gives an overview of a conceptual framework for the designing and implementation of an electronic trade platform. The trade platform prototype is the basis of a general conception for the design and implementation of internet-based trade platforms in agribusiness. The main platform focus related to the concept are to convert traditional business relationships and transactions into an electronic system. The conceptual framework provides clarification with regard to the benefit of trade platforms and the individual requirements of different value chains and chain levels.

Small farms still dominate the agricultural sector in much of the developing world and they are still significant players in the rural life of many rich countries. As part of the economic transformation process, rising labor costs drive most small farms out of business, and only part time farmers and a few small- specialized producers of higher value products survive. Historically this process has usually taken several generations to unfold, but the process may prove much faster in the future. New driver variables are quickening the pace, including the miniaturization of small farms under continuing rural population growth in poorer countries, the trade distorting agricultural policies of most OECD countries, a shift towards increasingly integrated and consumer driven markets as part of market liberalization and globalization, and the demographic impact of the spread of HIV/AIDS. The viability of small family farms is threatened today in all kinds of countries in historically unprecedented ways. Yet there are good reasons why policy makers should want to keep small farms around, and this will require deliberate policies to provide them viable development pathways in an increasingly hostile world. This paper reviews the problem and discusses appropriate policy interventions.

The paper introduces a general methodological approach for the estimation of constrained optimisation models in agricultural supply analysis. It is based on optimality conditions of the desired programming model and shows a conceptual advantage compared to Positive Mathematical Programming in the context of well posed estimation problems. Moreover, it closes the empirical and methodological gap between programming models and duality based functional models with explicit allocation of fixed factors. Monte Carlo simulations are performed with a maximum entropy estimator to evaluate the functionality of the approach as well as the impact of empirically relevant prior information in small sample situations.

In this article, we investigate welfare economic aspects of multifunctional agriculture, putting emphasis on the provision of rural environmental benefits. The formal analysis shows that the efficiency prices of agricultural and forest land include important amenity and non-use values that exhibit the character of undepletable externalities. Thus, to achieve a socially optimal land allocation these externalities must be internalised. We propose the compensation to agricultural and forest managers according to the marginal external benefit of their land, and a charge-subsidy scheme to improve rural water quality. Altogether, this is consistent with the requirement of optimal land allocation and would not cause additional market distortions. Moreover, it would leave the property right on the land and landscape benefits with the farmers, and assign the right on clean air and water to the consumers.

A model is presented to investigate the optimal economic life cycle of grass leys with winter damage problems in northern Norway and to determine the threshold of winter damage before it is profitable to reseed. A two-level hierarchic Markov process has been constructed using the MLHMP software. The model takes uncertainty concerning yield potential, damage estimation and weather dependent random fluctuations into account. A Kalman filter technique is used for updating of knowledge on yield potential and damage level.

The application of the model is demonstrated using data from two commercial Norwegian farms. Since parameter estimates vary considerably among farms, it is concluded that decision support concerning optimal economic life cycle of grass leys should be done at farm level. The results also show the importance of using a flexible dynamic replacement strategy. Use of the model for a specific farm situation is illustrated.

This paper explores the determinants of technical efficiency, and the relationship between farm size and efficiency, in the Center-West of Brazil. This is the region where agricultural production and total factor productivity have grown the fastest since 1970. It is also a region characterized by unusually large farms. Technical efficiency is studied with Data Envelopment Analysis and county level data disaggregated by farm size and type of land tenure. The efficiency measure is regressed on a set of explanatory variables which includes farm size, type of land tenure, composition of output, access to institutions, and indicators of technology and input usage. The relationship between farm size and efficiency is found to be non-linear, with productivity first falling and then rising with size. Access to institutions, credit, and modern inputs are found to be important determinants of the differences in efficiency across farms. Improved access could strengthen the efficiency advantage of small and medium farms.

A modelling system is presented and used to analyse the effects of EU dairy policy reform (Agenda 2000 and milk quota abolition with and without decoupled direct income payments) on Dutch agriculture and economy. The modelling system consists of a regionalised, agri-environmental, partial equilibrium, mathematical programming model of agriculture supply in the Netherlands integrated into a mixed input- output model. It was e.g. found that decoupling of direct income payments gives an extra stimulus to milk production after milk quota abolition. However, the increase in milk production is restricted by nutrient and manure policies in the Netherlands. It is also found that, although the total effect on Dutch GDP is limited, the income effects for individual industries can be large. Moreover, economy wide effects for non- agricultural industries exceed changes for agriculture.

A modelling system is presented and used to analyse the impact of milk quota abolishment on Dutch agriculture and economy. The modelling system consists of a regionalised, agri-environmental, partial equilibrium, mathematical programming model of agriculture supply in the Netherlands integrated into a mixed input-output model. It was found that abolition of the milk quota system has large impacts on milk production and livestock numbers and composition. The latter is explained by the strict mineral and manure policies in the Netherlands; an increase in the numbers of dairy cows leaves less room for other livestock. It is also found that, although the total effect on gross value added in the Dutch economy is limited, the effects for individual industries can be large.

The paper focuses on the implementation of direct aids modulation, as provided for by Regulation 1259/99. After a critical review of the most relevant questions arisen around the effectiveness and the viability of modulation, the paper presents results about its possible application in Italy. In the first part of the paper a special attention is given to the actual distribution of direct aids in Italy, to the number of farms involved and the amount of revenues realised. In the second part four different hypotheses of modulation are tested. In order to evaluate the effectiveness of modulation revenues under the four different hypotheses are compared with the financial resources allotted in Italy to the regional Rural Development Plans (RDPs). While results of modulation are, generally speaking, quite poor in terms of re-distribution of direct aids, there is a more relevant effect in terms of additional resources destined to the RDPs. However, resources are to be destined to measures that receive the highest share of resources within the RDPs. On the contrary, other measures, more genuinely addressing Rural Development and territorial issues within the RDPs, receive a much smaller amount of resources and cannot be funded through modulation. In other words, if the main objective of the modulation is that of shifting resources from the first to the second pillar of the CAP, this is only partially realised, given the mandatory destination of financial resources on measures that are substantially financed and that do not fully address the economic diversification and the development of rural areas.

The paper deals with the financial issues of the CAP reform at the edge of the EU enlargement, looking at the new distribution of resources programmed for the “second pillar” of the CAP. More in details, the papers focuses on three aspects: the distribution of resources coming from the implementation of modulation of direct payments, with regards to both the current and the new Member States; the future financial perspectives for Rural Development Regulation (RDR) in the framework of the cohesion policies, in the light of the proposal of a “single Fund” that include both Guarantee and Guidance sections of the EAGGF; the new distribution of resources for Rural Development Plans (RDPs) as it comes out of the “Objective Criteria” coming from the European Commission. Modulation of direct payments is the current only instruments that actively shifts resources from the first to the second pillar of the CAP. The proposal of a single fund would change the geography and the distribution of resources for the second pillar quite consistently. It would also affect the equity of the “objective criteria”, that would probably will be debated and eventually revised.

This paper examines intergenerational succession on Irish dairy farms. The factors that influence the decision to enter dairying farming are examined using a binary choice logit model. Reasons that are frequently published in the popular farming press as being an obstacle to intergenerational succession are analysed and the significance of their effect is quantified. Results show that the level of education of the heir is the most significant factor in the succession decision. Heir’s with third level education are 30% less likely to enter dairy farming than their second level only educated counterparts. The sizes of milk quota and income that are associated with high probabilities of succession are identified.
