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.

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.

In this paper we apply the technical inefficiency effect model to a set of eight different crop products (i.e., wheat, mixed arable crops, tobacco, cotton, olive oil, fruits, vegetables, and greenhouse horticulture) in Greek agriculture.

For each product, a panel data set covering the period 1991- 1995 is used and separate econometric results are obtained for each product. A particular set of socioeconomic and demographic variables is used to explain technical efficiency differentials among Greek farmers, including the direct subsidies given to each farmer, and the concordance of these efficiency determinants is discussed across the eight different crop products considered.

Empirical evidence suggests that agricultural futures price movements have fat-tailed distributions and exhibit sudden and unexpected price jumps. There is also evidence that the volatility of futures prices contains a term structure depending on both calendar-time and time to maturity. This paper extends Bates (1991) jump-diffusion option pricing model by including both seasonal and maturity effects in volatility. An in-sample fit to market option prices on wheat futures shows that our model outperforms previous models considered in the literature. A numerical example illustrates the economic significance of our results for option valuation.

Regional grain production in the Russian Federation has developed in a number of different ways over the last years. The same is true for grain marketing. Not only the prices on local markets but also those in the nation-wide grain trade seem to be at least strongly influenced by regional authorities.

However, it is very likely that only a small part of the grain trade is exchanged interregionally. The growing independence of the Russian Federation’s political subjects seems to be primarily responsible for regional differences concerning grain production and marketing. The 1998 economic crisis is likely to obstruct the development of an efficient domestic grain market further.

This paper examines the extent of interregional integration of Russian food markets from different perspectives. Though food price levels in Russia are converging after the period of hyperinflation, remote regions like the Far East seem to be on a different price path. With regard to the interregional commodity flows, it could be shown that interregional transportation of grain is unlikely to have decreased significantly, if the figures are corrected for imports and feed use. But a cross-sectional regression analysis using differences between regional production and consumption revealed that regional surpluses as well as deficits for all products tend to diminish, which means that the Russian regions increasingly rely on their regional production and not on interregional trade.

This paper discusses an approach to implement output quotas in the GTAP model which permits an endogenous adjustment of both the supplied quantity and the quota rent. Since the quota rent is interpreted as additional earnings of the factors used no change of the worldwide GTAP data base is required. Several modifications of the GTAP model and two exogenous coefficients are necessary. Considering uncertain values of one of the coefficients, systematic sensitivity analysis is applied. The abolishment of the raw milk quota in the European Union would lead to a remarkable decrease in raw milk prices in most member countries. The raw milk production increases in Denmark, Ireland, Luxembourg and the Netherlands while it declines in Greece and Portugal. In the other member countries the raw milk production changes slightly.

This paper is concerned with the impact of the BSE crisis in the UK and focuses on price transmission between retail and farm prices. From a theoretical perspective we show that market power has an effect on price transmission between retail and farm prices following a demand shock. The empirical results suggest that the impact of a food scare on farm prices to be more than double that of retail prices, the direction of this effect being consistent with the impact of oligopoly dominating the effect (if any) of oligopsony.

However, important in assessing the full impact of a food scare is the ability of consumers to switch into substitute products. This is also evident following the BSE crisis with the availability of substitutes contributing significantly to the overall impact on price adjustment.

The paper discusses the general need for institutional innovation in the Russian Federation. An attempt to establish a Market Information System for the agro-food sector in Tula Oblast is taken as an example illustrating specific implementation problems. From the experience gained in this case, the authors derive some recommendations for improving institutional change in the process of transition. Important issues here are the adoption of a more general approach towards human resource development, the scheduling of longer time horizons in support projects, and improved vertical and horizontal co-ordination within the institutional network.

The objectives of this paper are to examine consumers’ perceptions of Protected Designation of Origin (PDO) beef on the basis of a survey of consumers and buyers of beef.

The paper identifies a profile of PDO beef consumers, examines their behaviour and perceptions on PDO beef, derives the dimensions of perceptions of PDO beef, and establishes segments based upon those dimensions. The results reveal that PDO consumers are representative of all geographical regions, age and profession groups, are lighter consumers of beef and shop for food mainly in the butchers. Consumers’ perceptions on PDO beef emphasises quality, safety, and control. However, underlying those perceptions are six main dimensions and it is possible to identify three segments of PDO beef consumers: a faithful consumer group, an unaware consumer group, and a sensory, price conscious group.

Supply Chain Management as a business strategy can combine both microeconomic and macroeconomic aspects of preferred value chains. This paper
(1) shows the impact of SCM,
(2) stretches out the three dimensions of performance, costs and quality of the processes along the supply chain and
(3) highlights the SCM-enabler.
The method of a process chain analysis is demonstrated for the allocation of resources. Various results of carried out and studies in progress are given and identified through the classification into economical and management aspects.

The paper develops a measure of consumer welfare losses associated with withheld information about BSE linkage with vCJD. food safety. The Cost of Ignorance (COI) is measured by comparing the utility of the informed choice with the utility of the uninformed one, under condition of improved information. Unlike previous work, based on a single equation demand model, the measure is obtained retrieving a cost function from a dynamic Almost Ideal Demand System. The results indicate that Italian consumers bore a significant loss because of the delayed release of information.

Applied econometric analyses of market integration based on price data alone have been criticised, because they neglect the role of transaction costs. To meet this objection threshold vector error correction models are used. Threshold models can account for the effects of transaction costs in price transmission without directly relying upon information about these costs, which are often unavailable. Results from threshold models that are based on two thresholds provide results that are economically more intuitive than those obtained from one threshold models. However there is no adequate econometric test for threshold significance in a two- threshold model available so far; such tests are only available for the one threshold model. In this paper a restricted two-threshold model is developed in which the significance of the thresholds can be tested. This model is therefore amenable to economic interpretation and statistical inference. This model is used to estimate market integration on the European pig market.

This study deals with horizontal product differentiation in the Polish pig meat market. Hypothesis among firms behaviour are derived from an illustrative model and tested in an empirical analysis using data from 1991-1998. The empirical analysis suggest that product differentiation is a relevant phenomenon in the polish pig meat markets. In addition we found that costs and competitions are important factors influencing price variation. However, further influences like price discrimination and vertical product differentiation are also important determinants for product price variations.
