Only a few studies have analysed staggering and synchronisation in pricing behaviour of multi-product firms. These studies used low-frequency data in an environment of high rates of inflation. This paper investigates staggering and synchronisation of weekly prices for ten food products in 131 grocery stores in Germany over the period from May 1995 to December 2000 (296 weeks). Different forms of staggering and synchronisation (across-store synchronisation, within type-of-store synchronisation, within retailer synchronisation or across-product synchronisation) have been analysed. None of these forms of synchronisation is supported empirically however. In contrast, perfect staggering can only be rejected in very few cases.

The paper illustrates the theme of policies and especially the ones that could be applied for integrated catchment management and sustainable use of water, in the light of the implementation, in the EU, of the Water Framework Directive, by which, within 2015, all the member States and all the candidates, should reach a “good status” of water resources. The purpose of the paper is to clarify the double link existing, in complex systems, between policies and sustainable development of rural areas, where sustainability has to do with the conservation of natural resources and, in the specific case, water. This is also one of the central topics of the EU research project called SLIM. SLIM stands for Social Learning for the Integrated Management and Sustainable Use of Water at a Catchment Scale. It is a multidisciplinary European research project which main theme is the investigation of the socio-economic aspects of the sustainable use of water. Within this theme, its main focus of interest lies in understanding the application of social learning as a conceptual framework, an operational principle, a policy instrument and a process of systemic change.

This paper analyzes the functioning of land rental markets in the Dominican Republic using a new data set collected specifically to characterize the entire market. We analyze the choice of the landlords and the tenants in the search for the optimal partner. We show how insecure property rights leads to segmentation in the tenancy markets along socio-economic group and hence severely limits access to land for the rural poor.

Economic reforms have induced different output and productivity changes in Russia, China and the transition countries of Eastern Europe. The main objective of this paper is to analyze what has caused these differences in performance. We discuss how initial conditions and reform policy choices affect changes in property rights, production organization, terms of trade, and the liberalization of the economy. We analyze how these, in turn, have affected economic performance.

The hypotheses are tested by quantitative analysis. We conclude that it is a combination of both initial conditions and reform policy choices which has caused the differences in performance.

This paper analyzes the causes of the differences in transition performance in agriculture. The analysis draws on three empirical studies in which we estimated the impact of reform policies and initial conditions, and their 'intermediate results', (i.e. changes in relative prices, farm restructuring, changes in property rights and overall economic liberalization), on performance, i.e. agricultural productivity and output.

Two studies (Macours and Swinnen, 1999, 2000b) use aggregate data for 15 transition countries (as presented in figure 3); the third (Macours and Swinnen, 2000a) uses annual data on crop output for eight CEECs.

The demand for hedging against price uncertainty in the presence of crop yield and revenue insurance contracts is examined for two French wheat farms. The rationale for the use of options in addition to futures is first highlighted through the characterization of the first-best hedging strategy in the expected utility framework. It is then illustrated using numerical simulations. The presence of options is shown to allow the insured producer to adopt a more speculative position on the futures market. Futures are shown to be performing, in terms of willingness to receive. Options are weakly performing when futures markets are unbiased, while they are more performing when futures markets are biased.

When joining the EU, Finland was granted a permission to run its own food safety policy concerning Salmonella. The policy is called Finnish Salmonella Control Program (FSCP) and it covers the main animal production lines: pork, beef, poultry, and also the products thereof e.g. meat and eggs. By committing to follow an EU Commission approved national program Finland received so called additional guarantees from the EU. These guarantees allow it to require respective salmonella protection levels from similar products imported to the country. In order to continue the program its economic efficiency has to be thoroughly evaluated.

The objective of FCSP is that no more than 1 % of the animals and meat should be contaminated with Salmonella at the national level. Respectively, at the abattoir or meat cutting plant level the goal is 5 % . These quite strict objectives were reached well in 1995-2001. The industry is responsible for running the program in practice. National authorities have their emphasis in coordination, collecting of data and supervision. The costs of the program are almost fully carried by the industry. This paper evaluates the efficiency and viability of FSCP as a whole. It can be concluded, that money used running the program is well-spent: health benefits produced, estimated either using a cost-of-illness type of calculations or a willingness-to-pay measure from a consumer survey are many times larger than the costs of the program. In the end it can be concluded that FSCP is a good example of economically viable tool for sustaining public health.

We model today’s privatized crop research industry as a small number of firms, developing and selling differentiated products to heterogeneous producers. Crop variety research is modeled as a search process, which allows us to differentiate between applied and basic research and recognize research as a stochastic process. We use the framework to develop a number of propositions regarding private research incentives, the spillovers of knowledge, and the impact of public policy. The results suggest an underinvestment in research even when property rights have been established.

The purpose of this paper will be to develop and present a new approach for examining the demand for meat by incorporating many of the advances in behavioral economics. By providing a closer approximation to how consumers actually behave, doing so should improve upon existing models. Incorporating findings from behavioral studies will also provide a richer theoretical basis to correct for the longstanding problem of endogeniety in cross-sectional studies. The theoretical model in this study begins with the Becker household production model, where individuals are assumed to maximize utility, subject to their production functions, budget constraint and time constraint. To develop a model that more accurately depicts how individual’s make their food choices, this model additionally assumes that individuals 1) use household time to create food, health and relaxation; 2) make their food and nutrient consumption choices on a per-meal basis; 3) are affected by the prospect of immediate gratification, convenience and time delay, and 4) are more affected by these factors as their hunger increases.

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.

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.

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.
