In many industrialized countries, the grocery-retailing sector exhibits a strong and increasing market concentration. Hence, it is important to understand retail pricing for many questions related to market power in the marketing chain and to agricultural and food policies. We analyze intertemporal pricing of grocery retailers in Germany with a large set of scanner data for processed foods. In theory, food prices could be rather variable, e.g. due to fluctuating commodity prices in a competitive world, or rather rigid, e.g. due to price adjustment costs. We elaborate that retail sales are crucial and raise food price variability at the points of sale. Despite this, prices are rather rigid and often do not change for many weeks. Moreover, pricing strategies for identical brands vary strongly across retailers. Retailers seem to have differential pricing strategies and, thus, market power. This casts substantial doubt on the assumption of a competitive price transmission in the marketing channel underlying most analyses in agricultural economics.

This paper addresses the issue of rationality of responses in contingent valuation. We found a significant portion of respondents stated a positive willingness-to-pay for a project they perceived to be worthless. The irrational responses had a significant impact on the mean stated willingness-to-pay and the effect can not be removed by simply excluding the those observations from estimation. The dichotomous-choice elicitation format helps to mitigate the effect of the irrational responses, but can not completely solve the problem.

This book offers a coherent perspective on the transition to a market-based agri-food system in the Central and Eastern European Countries and the New Independent States of the former Soviet Union. It provides a formal analysis of the entire food chain from farm inputs to final consumers, including imports and exports, and covers all major components of the system, from food security, multinationals, and commercial law, to theoretical approaches to prices, transaction costs, and bilateral monopolies.

В книге представлен анализ перехода к основанной на рыночных условиях хозяйствования агропродовольственной системе в странах центральной и восточной Европы, СНГ. Авторами рассматривается вся продовольственная цепочка от фермера до потребителя, структура, задействованные экономические агенты, импорт и экспорт, проблемы продовольственной безопасности, роль транснациональных корпораций, процессы ценообразования, трансакционные издержки, институты.

The landscape in Austria is characterised by the high proportion of less-favoured areas (LFA). These cover 81 % of the total Austrian land area. Most is classified as mountain area (70%) with a small part classified as other types of less-favoured area. Mountain farming has the key role in safeguarding the sensitive eco-system and thereby the multifunctional landscape and the general living and working space. The mountain area still possess a high environmental quality and environmentally friendly agriculture and forestry extends over most of the mountain area. This is also important for tourism, which plays a major role in the Austrian economy. Austria has gained considerable experience with mountain farming subsidies and regional programmes specific to the mountain area over recent decades. Since the early 1970s a differentiated classification system has been the basis for defining support levels for mountain farmers. A revised classification system has been applied since 2001. The dominant objective for mountain farming policy is to maintain an agricultural and forestry sector based on environmental principles and small family farms. Under the 2000 – 2006 Rural Development Programme major alterations to the support scheme have been undertaken and support levels have been improved considerably for LFA farmers, and particularly for mountain farmers. The ex-ante evaluation and the mid-term evaluation were undertaken by the Federal Institute for Less-Favoured and Mountainous Areas in Vienna. This paper addresses key questions regarding the evaluation and the achievements of the new compensatory allowances schemes in Austria and will focus on the extent to which it meets the main objectives for mountain areas and other less favoured areas. The complementary contributions of other RDP measures, such as the agri-environmental programme to fulfil the main objectives, will also be discussed. In addition, a review of less–favoured-area payments of some other EU member states will be presented.

In this paper we develop a dynamic data-consistent way for estimating agricultural land use choices at a disaggregate level (district-level), using more aggregate data (regional-level). The disaggregation procedure requires two steps. The first step consists in specifying and estimating a dynamic model of land use at the regionallevel. In the second step, we disaggregate outcomes of the aggregate model using maximum entropy (ME). The ME disaggregation procedure is applied to a sample of California data. The sample includes 6 districts located in Central Valley and 8 possible crops, namely: Alfalfa, Cotton, Field, Grain, Melons, Tomatoes, Vegetables and Subtropical. The disaggregation procedure enables the recovery of land use at the district-level with an out-sample prediction error of 16%. This result shows that the micro behavior, inferred from aggregate data with our disaggregation approach, seems to be consistent with observed behavior.

China has made a major investment in biotechnology research. Genetically modified (GM) cotton is widely adopted and the list of GM technologies in trials is impressive. At the same time there is an active debate on when China should commercialize its GM food crops. The overall goal of this paper is to provide an economy-wide assessment of these issues under various scenarios. Based on a unique data from empirical micro-level study and field trial in China and a modified GTAP model, our results indicate that the development of biotechnology has an important impact on China.s production, trade and welfare. Welfare gains far outweigh the public biotechnology research expenditures. Most gains occur inside China. Policy makers should put less weight on the international dimension in making their decisions on biotechnology development.

A three period overlapping generations model is developed to investigate the impact of shorter life expectancy due to disease, on human capital investment decisions and income growth. This research is particularly relevant to Sub-Saharan Africa given the dramatic reduction in life expectancy due to HIV/AIDS and the potential lasting effects on growth. Our results indicate that as life expectancy shortens so does schooling inducing a lower growth rate of income. These relationships are even more pronounced for the African continent than for the rest of the world.

Intra-industry trade in agri-food products between Hungary and the EU is shown to be low and dominated by vertically rather than horizontally differentiated products, suggesting higher economic adjustment costs. Following recent empirical studies, we then test econometrically for the determinants of this trade using different measures of horizontal and vertical trade, and employing an array of popular explanatory variables. Results suggest that separating the measure of intra-industry trade into vertical and horizontal provides for better estimation and supports the contention that the determinants may differ by type of trade. In the regression analysis, the level of intra-industry trade is found to serve as a better dependent variable than the degree or share of intra-industry trade.

The objective of this paper is to provide a review of the broad effects of education in agriculture and examine some of the prospects and potential for the future. Worldwide about one-half of the labor force continues to be employed in agriculture. In the low income countries which account for about 55 percent of the world’s population, the share of the labor force that is in agriculture exceeds 65 percent, but in developed countries which account for about 15 percent of the world’s population, the share of the labor force in agriculture is only 5 percent (World Bank 2000). In what are now the developed countries, the long-term increase in agricultural productivity associated with advances in knowledge has been a major factor in the long-term transformation from an agrarian to an urban-based, service-oriented society (Johnson 2000).

The essay will be organized as follows: a conceptual framework, a summary of empirical evidence, prospects for rapid changes, and conclusions.

Land markets have received a considerable amount of attention in economic literature. Since the treatment of the topic covers various approaches, areas, and questions, it seems desirable to attempt an overview of the results. This paper devises a way in which to present a complete picture of the land market by drawing together the various contributions. The first step is to establish a method by which a market in its entirety can be defined. It is suggested that the application of Oliver Williamson’s “Four levels of social analysis” is an appropriate approach to be used in this endeavour. In the second step, the contributions to land market research are reviewed, according to Williamson’s scheme, within four broad categories:
(1) embeddedness,
(2) institutional environment,
(3) governance and
(4) resource allocation.
The topics covered include cropshare tenancy, land titling and registration, communal land ownership, farmland policies, credit access and land reform. The paper closes with some proposals for further research and a discussion of the value of the approach used.

This paper proposes an Economic Drought Management Index (EDMI) that could assist water managers to inter-temporally manage water reservoirs. The index’s main appeal is that it can be easily interpreted and that encompasses in a single number hydrological processes, structural constraints, water institutions’ rules and the economic benefits of the customers served from the supply system. An empirical application of EDMIs is performed for two irrigation districts in Andalusia (Southern Spain), that are managed under different institutional arrangements. Results for one district show that the region’s vulnerability to drought could be reduced following the interpretation of the EDMIs. For the other district, the index shows that water stocks are managed under nearly optimal criteria. This last result shows that there is an efficient level of drought vulnerability, and that increasing supply security levels would result in welfare losses.

During recent years, dramatic changes in the world food system have led to unprecedented competition between agribusiness firms. To compete in this environment, agricultural cooperatives should invest substantially in long-term activities such as R&D and advertisement. Co-operatives have a difficult problem in acquiring equity capital because the residual claimant (benefactor) is the patron of the firm, not the investor. This organizational design poses to cooperatives three investment constraints:
a) the free rider problem,
b) the horizon problem, and
c) the portfolio problem.
Empirical analysis utilizing a latent variable structural equation model and a large dual response survey suggests that in the U.S. member-patrons are more likely to invest in co-operatives which adopt well defined property rights policies and structures than traditional co-operatives characterized by vaguely-defined property right structures. Agribusiness co-operatives in the European Union are gradually adopting long-term financing methods that possess one or more of the characteristics found in successful U.S. ‘New Generation Cooperatives.’ However, it seems that they have paid less attention in designing their organizational structures (e.g., membership policies). This may inhibit their efforts to gain a competitive advantage over investor-owned firms.
