The technical and scale efficiency of Polish farms is analysed, using Data Envelopment Analysis. Efficiency differences are measured according to farm specialisation, in crop or livestock, at two points in time during transition, 1996 and 2000. The statistical variability of efficiency estimates is investigated. The efficiency results are reviewed in the light of confidence intervals provided by bootstrapping and of a summary measure introduced in this study ‘the coefficient of separation’. The inference analysis suggests that farms might be less efficient than revealed by the point estimates alone, and that they might not be clearly different from each other.

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.

The study evaluates the efficiency of government intervention using a vertical structured model including imperfectly competitive agricultural input markets, the bread grain market, and the imperfectly competitive food industry. To test for policy efficiency the actually observed bread grain policy is compared to a hypothetical efficient policy. To account for the sensitivity of the results in regard to the model parameter values computer-intensive simulation procedures and surface response functions are utilized.

At the beginning of the new millennium, a 150-year-old conceptual skeleton—the “political economy”—is rattling loudly in the closet. Marx described early on in his work that there is a close and circular relationship between the social conditions of a nation and its conditions for production—and consequently the economic development. In this context, institutional structures and social values as well as ways of thinking and attitudes of members of civil society are very important. In the current discussion of agricultural biotechnology for developing countries, this part of the Marxian analysis seems highly relevant, particularly for urban impoverished groups as well as resource-poor farmers and their families. This paper looks at the impact that today’s politicized discussion in Europe is having on public research for the developing world and proposes elements for building a bridge over the troubled waters currently dividing proponents and opponents of agricultural biotechnology.

Although there is increasing emphasis on targeting of improved technology towards poor and female farmers, few adoption studies assess the uptake of new practices by these groups in a comprehensive manner.

In this study, community members used the wealth ranking method to identify the different wealth groups in their communities, to determine each household.s wealth status, and to assess the association of wealth and different types of households with the planting of improved tree fallows, a practice for improving crop yields. There were no significant differences between the proportions of women and men planting improved fallows nor were there differences between single women and female heads of households who were married. There was some evidence of association between planting improved fallows and wealth. That 22% of the .poor. group and 16% of the. very poor. group were planting them suggests that there are no barriers preventing low-income households from doing so. Moreover, the proportion of females, poor, and very poor people planting improved fallows varied considerably among villages, suggesting that opportunities exist for increasing their use of the technology. Whereas the use of mineral fertilizer is strongly associated with high- income, male farmers, improved fallows appear to be a gender-neutral and wealth-neutral technology. Poor farmers appreciate improved fallows because they permit them to substitute small amounts of land and labour for cash, their most scarce resource. Finally, the high degree of consistency among different key informants in classifying households among wealth groups confirmed the effectiveness and accuracy of the wealth ranking exercise.

We introduce an easily implemented and flexible calibration technique for partial demand systems, combining recent developments in incomplete demand systems and a set of restrictions conditioned on the available elasticity-estimates. The technique accommodates various degrees of knowledge on cross-price elasticities, satisfies curvature restrictions, and allows the recovery of an exact welfare measure for policy analysis. The technique is illustrated with a partial demand system for food consumption in Korea for different states of knowledge on cross-price effects. The consumer welfare impact of food and agricultural trade liberalization is measured.

The paper analyzes the changes that have taken place in the nature of agriculture information and their consequences on the public role of related public services with specific regard to process undergoing in the European Union. Increased interest in food quality and food safety issues in a global consumer driven society, together with major attention to environmental and ethical issues related to food production, enlarge both the object of agricultural information and the audience of stakeholders in the food chain and in the general public. Information policy with regard to a multifunctional approach to agriculture, can be finalized to correct three main sources of market failures as access to information, quality and adverse selection and externalities and provision of public goods. The privatization of agricultural research and extension, although useful from the point of view of economic efficiency, poses a number of threats to the development of knowledge for sustainable agriculture. If the public sector decides to move away from the delivering of services, public action can still be relevant in orienting, targeting, regulating and funding in win-win solutions where the advantages of public extension, as open access and evaluation of social priorities, join efficiency and market orientation of the private sector.

This paper focuses on the consequences that an extension of the Common Agricultural Policy could have on agricultural production in the Central and Eastern European Countries. It reviews the evidence presented by recent attempts to quantify the potential impacts of accession on production levels in the CEECs. It also takes into account results from previous studies in order to analyse the importance that structural constraints might have on the capacity of the CEECs' agricultural sectors to respond to supply incentives under accession to the EU, and to examine some research questions that are still unanswered in relation to the supply potential of the CEECs. Some conclusions and policy recommendations are drawn at the end.

The set of policy tools that the EU puts under the heading of Rural Development is extremely heterogeneous, such heterogeneity translates into a different degree of coupling support with agriculture production and also brings out the need to discuss the actual consistency of such tools with the UE position on NTCs at WTO. Examined in the present work are the Rural Development Plans (RDPs) and the Regional Operative Plans (ROPs) recently approved by the European Commission for the Italian Regions. The analysis is of a purely qualitative type and is based on currently available information, that is, the measures and the relative project typologies approved within the Plans. Taking into account the EU position on NTCs and their relation with multifunctionality we look at the tools applied for Rural Development in Italy with respect to their degree of de-coupling, production of externalities/non marketable goods and consistency with the EU position on NTCs. Financial allotment by measure typology is also examined. We found out that the present set of actions that fall under rural development is still dominated by a sector-based intervention, even in the case of measures aimed at safeguarding the environment, the least contestable ones. Paradoxically, the measures aimed at the promotion of Rural Development and at training, that better respond to the NTC objectives, are those for which the least resources are located.

In this paper the incremental values of water are calculated for irrigators in the Fish-Sundays Scheme of South Africa's Eastern Cape province. The socio-political pressure for redistribution of agricultural resources provided the imperative for this study. The model of the Fish-Sundays Scheme reflects a survey of 50 000 ha of fodder and citrus production. It explicitly models the water demand on sixteen typical farms, for five irrigation technologies, six crops and four livestock activities. The existing allocation generates an average value of R0.0423/m3/year, which increases to R0.0681/m3/year if farmer-to-farmer trading is allowed given existing infrastructure. Unrestricted trade raises the average value to R0.0719/m3/year. The marginal cost of additional water in the source basin is R0.05/m3/year for the first 315 million m3 and R1.27/m3/year to extend capacity beyond that.

Germany is the second important coffee market in the world, just overshadowed by the United States. Coffee is the most famous beverage in Germany – even more popular than beer. On the supply side dominate few roasters. Market structure influences the market outcome and explains the processors’ ability to exercise market power. This paper aims at studying the pricing behavior in the German market for roasted coffee. Respectively, it discusses the impact of three different explanations. First, market power may be due to low price elasticity related to a high level of consumption. Second, pricing behavior may be influenced by the industry concentration. And finally, pricing behavior may be change over time due to exogenous shocks. In particular, the degree of competition has changed as a consequences of a merger. Further, cyclical demand changes induce pricing behavior. Empirical results are derived using data on the aggregate market for roasted coffee in Germany during 1992:1 to 2000:12.

On farm conservation of crop diversity entails policy challenges, especially when the diversity of crops maintained on farms has both inter-specific (among crops) and infra-specific (within a crop) components. Survey data is used to compare the determinants of inter- and infra-specific diversity on household farms in the highlands of northern Ethiopia. Physical features of the farm, and household characteristics such as livestock assets and the proportion of adults that are men, have large and significant effects on both the diversity among and within cereal crops grown, varying among crops. Demographic aspects such as age of household head and adult education levels affect only infra-specific diversity of cereals. Though there are no apparent trade-offs between policies that would enhance one type of diversity (richness) versus another (evenness), those designed to encourage infra-specific diversity in one cereal crop might have the opposite effect on another crop. Trade-offs between development and diversity in this resource-poor system are not evident. Market-related variables and population density have ambiguous effects. Education positively influences cereal crop diversity. Growing modern varieties of maize or wheat does not detract from the richness or evenness of these cereals on household farms.
