This paper analyses the impact of the dairy quota scheme on the size distribution of the Dutch dairy industry. A non-stationary Markov model approach is used, where the transition probabilities are explained by a set of exogenous (policy) variables. Using an information theoretical approach, a model is estimated for The Netherlands and used to simulate the impacts of alternative EU dairy policies. Several results emerged:
a) There is an autonomous over time decline in farm numbers (implying increase in farm size).
b) The dairy quota regime positively influences 'small' and 'medium' farm sizes;
c) Abolition of the dairy quota will negatively affect the total number of active farms and favours further increase of farm scale.
d) Targeting support according to needs increases the number of active dairy farms as compared with the status quo.

Community based health insurance schemes are becoming increasingly recognized as an instrument which help farmers in rural areas of low income countries to better manage health. Health risks present a permanent threat to the income earning capacity of poor people. Beside direct economic cost for treatment and lost working time, indirect cost such as a reduction in labor supply materialize which increases the vulnerability of the household. It is often hypothesized that community based health insurance improve social protection, but quantitative analysis is largely missing. Against this background, this paper analyzes if members in a mutual health insurance scheme have a better access to health care than non-members taking “les mutuelles de santés” (mutual health organization) in rural Senegal as an example. Limited dependent and log linear regressions are used to capture the impact of health insurance on the probability of visiting a health care provider and the out-of-pocket expenditure at the point of use . The results of the analysis show that while community based health insurance schemes reach otherwise excluded people, the poorest of the poor in the communities are not covered. Regarding the impact on the access to health care, members have a higher probability of using hospitalization services compared to non-members and pay substantially less when they need care. Given the results from this study, community financing schemes have the potential to improve the risk management capacity of rural households.

The paper attempts to quantify determinants influencing dynamics of employment decisions on agricultural households in Slovenia and to test specific aspects of labour reallocation during transition period by application of agricultural household model. Through the use of 1991 . 2000 panel data for 22,055 farm households, quantitative analysis of intertemporal employment decisions of farm holders is carried out by the use of probit techniques. Determinants tested refer to personal characteristics of reference persons (gender, age, education level, opportunity off-farm income), household characteristics (size, structure), characteristics of the agricultural holding (economic size, labour input, labour intensity) and local labour market conditions. The model results generally confirm the existing empirical evidence on asymmetrical and irreversible participation of holders at the labour market. Despite intensive restructuring of agriculture and profound changes in non-farm labour market in the analysed period, labour supply of farm holders remains rigid. Mobility of labour supply is lower than expected, which can be attributed to the importance of structural problems constraining intersectoral mobility. A marked tendency towards upkeeping of the same employment status is more distincted in the case of holders employed on the farm. A low level of labour supply mobility worsens efficiency of labour allocation on agricultural holdings in Slovenia. Elements of this problem emerge on both, supply (e.g. low level of educational and professional attainment of reference persons) and demand side of labour market (e.g. unfavourable local labour market conditions).

In comparison to large-scale natural landscapes separated from extensively used agricultural production landscapes in North America or Australia, German and Central Europe landscapes are all characterised by predominantly agricultural landscapes with few “rests of nature”. Due to the high population density, different types of land users demand different functions of the landscape. In addition to food production, there is a high demand for protection of cultural heritage by caring for e.g. hedgerows in the landscape. The aim of this study was to estimate the costs arising from the maintenance of landscape elements in landscapes situated on land with different site conditions. As an example, the distribution of hedgerows on sites of varying agricultural quality were considered. The calculations were undertaken on the entire area of Baden- Wuerttemberg in Southwest Germany, comprising various administrative districts. The association between ecological and economic information was analysed statistically and with the help of GIS. The results indicate that the costs for landscape element protection differ within the state of Baden-Wuerttemberg and that there is a lot of economic pressure against hedgerow biotopes existing in certain districts. Measures for protection such as agri-environmental programmes should consider the different landscape-dependent costs.

The objective of this paper is to develop a tractable approach for recovering and quantifying all sources of TFP changes (namely, technical change, changes in technical and allocative efficiency, and scale economies) from the econometric estimation of an input distance function which also fully describes the production technology. The proposed theoretical framework relies on Bauer’s TFP decomposition framework and the duality between input distance and cost functions. Hence, instead of using a system approach to estimate a cost frontier, all necessary information for decomposing TFP changes are recovered from its dual counterpart.

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.

This paper examines the welfare effects of the Common Agricultural Policy (CAP) cotton, maize and sugar beet regimes practiced in Greece after its 1981 entry into the European Union. These markets are considered as horizontally related because there are usually the same farmers that use the same areas to produce various combinations of the relevant products. We use bootstrap techniques to conduct a statistical analysis of the estimated welfare measurements. The welfare analysis indicates that the income amounts transferred to farmers rose significantly in the period between 1981 and 1992. The 1992 CAP reform slowed down this trend, and transfers have remained at an almost statistically constant level since 1992.

The paper argues that current long-term projections of global meat and feed demand may underestimate future consumption patterns for mainly two reasons. First, they do not explicitly consider increased demand for protein foods of animal origin with rising incomes in some developing contries, and second they do not allow for changes in livestock technology, in particular feed demand. We then project the impact of both mechanisms to show the empirical relevance of our comments and suggest ready-to-use tools to consider them within standard projection models.

Country of origin labeling and brand labeling play important roles in affecting purchasing behavior of buyers in the Korean beef supply chain. This paper presents a model which explain differences in the attitudes and purchase behaviors of three marketing groups regarding country of origin and other important quality attributes. The results show some of the diversity of buyers’ attitudes, preferences and willingness to pay for different country of origin and brand of foreign packers in three marketing groups.

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.

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.

In contrast to expectations held by western observers in 1990, the farm structure in the Central and Eastern European Countries and the Countries of Independent States has not converged to the one prevailing in the West. In particular, remarkable changes in Russian agriculture in recent years have let to the emergence of new agricultural holdings combining under one umbrella many large farms. Does this unexpected development, unprecedented even in the West, contradict conventional wisdom about the determinants of farm size in agriculture? This paper argues that in transition economies external institutions seem to be more important than economies of scale and transaction costs on the farm in determining farm size. Whilst the birth of family farms in Russia seems to have been mainly constrained by embedded institutions of could-be family farmers and partly by second level institutions, the survival and the creation of holdings has been strongly supported by second and third level institutions, but embedded institutions have played also a role. Consequently, recent developments in Russia do not support the view that large farms or even holdings are more efficient than small or medium size family farms in an environment, which prevails in western market economies.
