Community legislation requires that the programme for rural development is evaluated. A detailed set of indicators was developed by the commission and member states are required to use them to measure program success. To make results comparable requires that the methodology by which indicators are measured is well defined. However, this is not the case in this evaluation task. We take a small set of indicators and use two different approaches using the same sample and show that the results are deviating. We conclude that the success of this programme can only be compared across measures/regions when both, indicators and method are the same.

Projections of world food demands hinge critically on the underlying functional form used to predict future demands. Simple functional forms can lead to unrealistic projections by failing to capture changes in income elasticities of demand as consumer becomes wealthier. This paper compares several demand systems in the projection of disaggregated food demand across a wide range of countries with different income levels using a global general equilibrium model. We find that the recently introduced AIDADS system represents a substantial improvement over existing demand systems currently in use in CGE modeling. In particular, our projection results show that for relatively poor regions experiencing rapid income growth, the widely used LES and CDE demand systems tend to over-predict growth in consumer demand, and hence import and output requirements for food products and under-predict that for non-food products, compared to the AIDADS system. On the other hand, for high-income regions with modest income growth, the choice of functional form is less critical.

Offers a definitive study of agricultural labor in California and an overview of the subject in the Southwest. It explores the agricultural industry, immigration, ethnic relations, agribusiness, agricultural workers, and public policy as related to the region and to the agricultural sector of the U.S. economy.

The objective of the paper is to identify the determinants of access to health care in rural Russia. We started out with the observation that the transition process has affected the provision of social services in the Russian Federation in general, and in rural areas in particular, owing to the overlap with agricultural reforms. Based on this observation we asked how the reduced role of the state and the concomitant decentralization of policy making has affected access of the rural populace to social services. A review of the available literature on this topic resulted in the formulation of the following three hypotheses. Firstly, that income is a determinant of access to health care. Secondly, that informal payments play an important role in determining access, and thirdly that there are large differences in access to health care services between districts. The hypotheses were tested using household data from a survey conducted in two regions of Russia in 2000. The results indicate that in the study regions, contrary to expectations, neither income nor informal payments are important determinants of access. However, there are large differences in out-of-pocket expenditures between districts, indicating that access to health care varies between districts.

China’s accession to the WTO poses great challenges to the Chinese agricultural sector, especially to the grain producers. Compared with major grain exporters in the world, most grain crops in China are high in production cost and weak in market competitiveness. This can be partly attributed to the fact that Chinese farmers are facing with poorer agricultural production infrastructures and inadequate public investment in agricultural research and extension, which leads to the lower efficiency in private inputs and thus higher private cost per unit of product. After China joining the WTO, protective and administrative measures conflicted with the URAA cannot be utilized as before. Alternative measures should be explored to provide help to farmers to improve competitiveness of their product. Public investment in agricultural research and other production infrastructures should be considered with high priority as one of the policy alternatives.

This paper examines the effects of public investment in agricultural research on the reduction of production cost of major grain crops in China by using crop-specific data for the past 20 year. It is concluded that, increasing public investment in agricultural research, which is well within the ‘green box’ policy framework and allowed by the WTO rules, is a plausible and effective measure to reduce grain producer’s private input and to enhance the competitiveness of grain products. It is also of great significance to sustained food security in China.

Increased consumption of vegetables may reduce obesity and the prevalence of cardiac diseases and cancer. Norwegians consume less vegetables than nutrition experts recommend and the per capita consumption is lower than in most European countries.

To investigate the causes of low consumption, a two-step approach is used to estimate the demand segmented by nine different household types. In the first step, a probit model is estimated to investigate the decision whether to purchase traditional vegetables, salad vegetables, and industrially processed vegetables. Conditional on purchase, an almost ideal demand model is used to model how much to purchase. The own-price elasticities and total expenditure elasticities are high for traditional and industrially processed vegetables for most household types. Especially households with children have elastic demand. Lower value added tax or lower import tariffs for traditional and industrially processed vegetables will increase the demand for these vegetables, while reducing the price of salad vegetables seem to have a limited effect. For households with children, increased incomes have large effects on the demand for traditional and industrially processed vegetables indicating that, for example, increased child support will result in increased vegetable consumption.

The public R&D capital stock is introduced as a quasi-fixed input in a variable cost function. The relative shadow price allows the correct measurement of the equilibrium levels of quasi-fixed inputs thus explicitly assessing the hypothesis of public R&D under (over) investment. By introducing an appropriate R&D price in the long-run equilibrium, the model can also provide empirical evidence on the rationale driving public R&D investment and on the hypothesis that free-riding on public R&D can explain overinvestment. Moreover, the model allows a formal testing of the induced innovation hypothesis and a more accurate calculation of both internal rate of return to R&D and residual exogenous productivity growth. The empirical implications of the model are appraised in the case of Italian agriculture for the period 1960-1995.

Most food products can be classified as ‘credence’ goods and regulations exist to provide consumers with a substitute for the lacking information and trust. The paper presents an analysis of the decisions of producers and consumers about a ‘credence’ good in three institutional scenarios, which reflect different levels of credibility of the regulation.

The first scenario is a reference scenario in which the regulation is fully credible. In the second case considered there is no regulation, or, if there is, it is totally ineffective. In the third scenario a regulation only partially credible provides consumers with an imperfect substitute for the information and trust they lack. Some of the producers of ‘low’ quality goods share with the producers of .high. quality goods an interest in the introduction of a regulation as long as this is not fully credible. In addition, it may be the case that even producers of ’low’ quality goods who know they will not be able to sell their products labeling them as being of ‘high’ quality may have an interest in supporting a not fully credible regulation. Finally, rather than having producers of ‘low’ quality goods ‘block’ the introduction of a fully credible regulation, producers of ‘high’ quality goods are better off when a compromise is reached which leads to the approval of an imperfect regulation.
