The European tomato market is characterised by a constant process of dynamic adjustment toward the equilibrium. Furthermore, Canary tomato exports cause a high seasonal impact on market prices in the winter period. In these circumstances, an adequate distribution of shipments throughout the campaign could contribute to maximize producers’ profits. The goal of this paper is to analyse the seasonal pattern of Canary tomato exports to Europe throughout the first fourteen campaigns following Spanish integration into the European Union. These export levels show some degree of instability, clearly related to the changes in the European Union trade rules, and there is a long period, the summer, without exports. Moreover, we have opted by using weekly data. These factors should be taken into account in order to accurately capture the performance of exports and, specifically, the nature of their seasonal behaviour. Thus, this analysis is carried out inside the frame delimited by the structural approach to time series and the usefulness of spline functions as an alternative to standard seasonal variation models is shown.

The paper argues that current long-term projections of global meat and feed demand may underestimate future consumption patterns for mainly two reasons. First, they do not explicitly consider increased demand for protein foods of animal origin with rising incomes in some developing contries, and second they do not allow for changes in livestock technology, in particular feed demand. We then project the impact of both mechanisms to show the empirical relevance of our comments and suggest ready-to-use tools to consider them within standard projection models.

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 uses data from a survey of two hundred and fifty cattle keeping households in three cattle keeping systems; intensive, semi-intensive and extensive systems to estimate the value of non-market, socio- economic benefits of cattle in Kenya. These benefits of cattle keeping are of special importance in developing countries, where financial markets function poorly and opportunities for risk management through formal insurance generally absent. However, when estimating the total contribution of livestock, these non - market functions are often ignored since they are difficult to value, yet they may contribute to a better understanding of livestock production systems. The use of contingent valuation method is employed in this study to elicit these non-market values. Econometric estimations are then used to assess the factors influencing the non - market benefits function. The results indicate that these benefits are highly valued by cattle keepers and comprise approximately 20% of the animal.s total value across the three systems. They are influenced by various production system and household related factors. Implications for policy are drawn.

My aim is to follow Yair Mundlak's recommendation, which concluded his Elmhirst Lecture, to identify sources of and constraints upon economic growth in agriculture. I come to the subject not as a long-time researcher on international agricultural development, but rather as a follow-up to studies of the development of U.S. agriculture. The story of U.S. agriculture led me, as many before, to consider possible lessons for countries where sustained growth in the real incomes of rural people has not yet occurred. Moreover, my U.S. research led into questions of how the relatively poorest farm people have fared in the growth process (Gardner, 2000), a topic which fits well with the emphasis of President von Braun’s address.

I begin by revisiting some fundamentals of agricultural development economics, the literature concerning it, and data measurement issues. In the second major section, empirical evidence is reviewed on the growth of agriculture as an industry. The third section turns to welfare consequences of agricultural growth as measured by real household incomes. The final section discusses conclusions about the causes of sector growth and real income growth.

We analyse the competition in quality and quantity between a foreign firm and a domestic firm. The domestic firm can belong to a certification of origin, whereas its rival uses a pure brand strategy. We will show how the certification can allow the domestic firm to position itself as a high quality producer and improve the average quality of the products offered on the market. If, however, the certified firm offers the low quality good, the certification can permit it to guarantee a higher profit than that of its competitor and to improve the consumers’ surplus by favoring product standardisation.

Over the past decades child stunting in Ethiopia has persisted at alarming rates. While the country experienced several droughts during this period, it also received enormous amounts of food aid, leading some to question the effectiveness of food aid in reducing child malnutrition. Using nationally representative household surveys from 1995-96 and controlling for program placement, we find that children between 6 and 24 months experienced about 0.9 cm less growth over a six-month period in communities where half the crop area was damaged compared to those without crop damage. Food aid was also found to have a substantial effect on growth of children in this age group. Moreover, on average the total amount of food aid appeared to be sufficient to protect children against plot damage, an encouraging sign that food aid can act as an effective insurance mechanism, though its cost effectiveness needs further investigation.

Present-day Central and Eastern European agriculture is characterized by a high incidence of small-scale farmers who are not producing for the market. This paper uses household level data from comparative farm surveys in Albania, Bulgaria, Hungary and Romania to analyze which farm household characteristics and endowments influence commercialization and subsistence farming.

This study compares the predictive performance of several mathematical programming models. Using the cropping patterns, yields and crop gross margins of eighteen farms over a period of five years we compare the models’ optimum solutions with observed crop distributions after the Reform of the EU Common Agricultural Policy of 1992. The results show that the best prediction corresponds to a model that includes expected profit and a qualitative measure of crop riskiness. The results suggest that, in order to obtain reliable predictions, the modelling of farmers’ responses to policy changes must consider the risk associated with any given cropping pattern. Finally, we test the ability of the proposed model to reproduce the farmers’ observed behaviour with equally good performance under conditions of limited data availability.

As biotechnology evolves new methods of genetic engineering are now being applied to the production and processing of foods. This paper is trying to explore the attitudes of the European consumers towards genetic modification of food. Using survey data of the EU member countries the proposed research paper is planned to have a threefold output: 1) providing a comparative ranking of the EU member countries in relation to the prevalence of rejection of genetically modified food, 2) uncovering intra-european differences in genetic food engineering rejection as being based on socio-demographic and informational resp. knowledge based differentials between EU countries and 3) specifying the importance of socio-economic and informational determinants of a potential defender of genetically modified food by estimating the partial effects of age, gender, education, income, family status, size of household, knowledge on genetical food engineering and information use behavior in a multivariate model of the attitudes towards genetically modified food. This causal approach will be followed in selected EU countries representing extreme positions in the EU attitude ranking. By these empirical results the paper is trying to reveal intra-EU differentials of consumer attitudes towards genetically modified food, which is a necessary baseline for adequate and efficient policies in order to satisfy consumer needs for quality and security. The results will also prove helpful to the food industry providing differential information for marketing decisions and focusing adjustments in different EU food markets.

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.

Recent food scares in the food market has caused a reduction in consumer’s confidence in the food system that it has induced a significant reduction in consumption in a sector, the beef sector that was already characterized by a saturated trend in quantity terms. In this context, all participants in the beef production system are facing to a greatchallenge, to retrieve consumer’s confidence in the food chain and to mitigate the reduction in beef consumption. The aim of the paper is to analyse the impact of consumer’s confidence in the food system as well as other factors on the explanation of food consumption reduction. A structural modelling approach has been used to analyse factors affecting the reduction in beef consumption in two different regions characterised by different production systems and different marketing strategies (PGI beef label). Results indicate that main factor explaining the reduction in beef consumption is the confidence in the beef and a positive relation has been found. Moreover, confidence in a product is directly related to the perceived quality offered by farmers and other decision makers on the beef chain, and to the consumer involvement with the product. Therefore, the main implication is that participants in the food chain has to develop adequate communication strategies such as quality labelling in order to increase consumers perceive quality because, higher quality perception will recover consumers’ confidence in beef, and therefore, it will mitigate beef consumption reduction.

Formerly neglected, typical food products nowadays support a higher involvement of an increasing number of farmers as well as they seem to be in phase with consumers’ expectations. Since directives 2081/92 and 2082/92 European Union had set up PDO and PGI labels as means of valorisation with benefits to typical food products. This paper aims firstly at considering typical food products with respect to consumer perception and secondly at pointing out some methodological results on consumer survey approach. The conclusion is focusing on the commercial development of typical food products.

The present study attempts to offer more insights into the Greek wine market with emphasis on wines produced from organically grown grapes by relating wine choice to consumers’ personal value structure. With the use of a qualitative sample and applying the Means-end Chains methodology and the corresponding “laddering” interviewing technique, it attempts first to reveal the way basic motives are linked to wine shopping behaviour of consumers and the way wine purchase-relevant knowledge is stored and organised in their memory in relation to their personal values. Then, by discriminating between organic food buyers and non-buyers, the study identifies motivational and cognitive discriminating differences between the two consumer types, which can offer a solid explanation as to their distinctive purchasing behaviour in respect of the organic products.

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.
