The objective of this paper is to empirically detect credit rationing of Polish farms. Based on cross-sectional survey data and motivated by a microeconomic farm household model, this effort is pursued by a methodology consisting of three interrelated steps. These steps include the analysis of qualitative survey data regarding farmers’ experience with bank credit, based on this an econometric estimation of internal shadow prices of credit for the credit constrained sub-sample of respondents, and finally an investigation of interdependencies between determinants of consumption and production that should be influenced by the presence of a binding credit constraint. The results of the empirical analysis consistently suggest that among the observed randomly selected Polish farms more than 40 percent of borrowers experience pronounced credit rationing by rural banks. These farms display internal shadow prices of the credit constraint of on average 190 percent net of principal. Shadow prices are significantly different from individual effective interest rates for credit that account for loan specific transaction costs. In the group of credit constrained farms, household characteristics could be proven to have a significant effect on output supply. This is evidence for a violation of separability between production and consumption decisions and thus lends empirical support to the existence of a binding credit constraint. Overall, credit constrained farm households own less and rent more land than the average, operate with a high capital intensity with regard to land, tend to have a poor credit history, and engage intensively in intra-village conversation. Generous government support via interest rate subsidisation apparently contributed little to alleviate credit rationing of farms in Poland.

This paper draws upon a consumer survey carried out in Bucharest (Romania) to explore determinants of food choice in a transition economy. An adapted version of the Theory of Reasoned Action was developed. This included attitude toward intention, habit and preference as independent variables. The structural equations modelling carried out in 'Analysis of MOment Structures' AMOS showed a significant positive influence of all variables. Similar to other studies conducted in European Union (EU) countries (Saba, Di Natale, 1998) habit outweighed the other variables. The study emphasises the heterogeneity of consumer beliefs about food. Furthermore it was suggested that there is scope for noneconomic variables in explaining food choices and consumer behaviour in these emerging economies, though the influence of these variables may be still limited relative the economic factors. Further research on special groups is required to quantify the influence of non-economic factors and compare the results estimated in Romania with other countries which are candidates to EU accession.

This study deals with horizontal product differentiation in the Polish pig meat market. Hypothesis among firms behaviour are derived from an illustrative model and tested in an empirical analysis using data from 1991-1998. The empirical analysis suggest that product differentiation is a relevant phenomenon in the polish pig meat markets. In addition we found that costs and competitions are important factors influencing price variation. However, further influences like price discrimination and vertical product differentiation are also important determinants for product price variations.

This paper estimates farmer decisions between three discrete occupational choices: exit and close down the farming operation (1), exit and transfer the farm to a new entrant (2), or continue farming and retain the option to exit later on (3). The farmer optimisation problem is formulated as a recursive optimal stopping problem. The unknown parameters are first estimated by a switching-type, reduced form Probit models and, then by the Simulated maximum likelihood (SML) method, controlling for serial correlation in the errors. Serial correlation in the errors is controlled for by the Geweke-Hajivassiliou-Keane (GHK) simulation technique. The results suggest that the timing and the type of farmer exit decisions respond elastically to farmer characteristics, farm characteristics, and economic environment. Early retirement programs and the level of farmer retirement benefits are predicted to play a key role in steering structural development and enhancing family farms in the Nordic agricultural sectors.

Drawing on a grounded theory research we present a model of organizational improvisation which asserts that this phenomenon is triggered by an unexpected important event brought about by a moderate level of turbulence, relying on a minimal structure and simple resources. The success of improvisation is shown to be affected by the level of equivocality and by the perceived level of task complexity, and results in increased group cohesiveness and faster and less costly future actions. In conclusion the authors argue in favor of a contingency view of organizational improvisation and contend that our model suggests the possibility of a dialectical approach to organizational improvisation.

This study examines consumer willingness to pay for irradiated beef products. About 58 percent of the respondents are willing to pay a premium for irradiated beef. An ordered probit with sample selection model was estimated. Standard errors of the marginal effects of the ordered probit model were estimated using the bootstrap method. Our findings suggest that females and those who think that improper handling contributes to food poisoning are more likely to pay a premium of 50 cents per pound of irradiated beef than others. Those who trust the irradiation technology are also more likely to pay a premium of between 5 to 25 cents per pound for irradiated beef. Supply chain implications are discussed.

I develop a two-stage political economy model that explicitly models the complexity of decision-making in the European Union on the Common Agricultural Policy, and I derive how the institutional design affects the outcome and the influence of the various agents involved, and the likelihood of political stalemate.

In this paper a theoretical and empirical model is developed for analysing the decisions of individual farmers whether or not to produce wildlife and landscape services, how much of these services to produce and form an environmental co-operative in order to reduce transaction costs or to build up bargaining power. The model is applied for Dutch dairy farmers as the main users of agricultural land in the Netherlands. Simulations show that the reduction of transaction costs makes it attractive for farmers to form an environmental co-operative in case of a fixed price for wildlife and landscape services. Therefore more wildlife and landscape services are produced and more farmers are involved compared to a situation with individual supply. If demand is no longer perfectly elastic an increase in wildlife and landscape services production leads to lower prices offsetting part of the production and profit increase caused by lower transaction costs. However, if the environmental co-operative acts like a monopolist its bargaining position leads to a decrease in the production of wildlife and landscape services and higher prices.

This article presents results from an experiment into attribute perception and relevant levels for management of woodland and mountain areas typical of the Iberian Peninsula's Atlantic region. The aim, which the authors argue has been robustly reached, was to identify those aspects of forestry policy clearly perceived by citizens. This is useful for defining enlargement of areas protected under Natura 2000 Network. Results show clear preference for an increase in woodland to over half the current surface area, with replanting of traditional trees, in woodlands of low density and trees of different age and, preferably in irregular shaped plots.

It is well known that rural tourism and, agro-tourism in particular, represents one of the ways of exploiting rural development. It was considered, therefore, that an analysis of the territorial distribution of tourist resources might offer useful information for an assessment of the Community programmes, and in particular, measures regarding aid to agro-tourism enterprises. The aim of this work is to examine the impact of carrying out the structural policies of the 1994-99 programme for the Calabrian agro-tourism enterprises and also provide useful information regarding the new 2000-06 programmes.

This paper presents an analysis and evaluation of the impacts of rural development policies implemented in the rural town of Archanes, an area in Crete which has received considerable rural development funds during the CSF I and II. A hybrid interregional Social Accounting Matrix approach is used to describe interlinkages between Archanes and neighbouring rural and urban localities. Then, preliminary results are reported on the diffusion- patterns of rural development policy impacts in terms of generated output and income. Results show that policy-related economic benefits leak primarily to the ’affluent’ urban area of Heraklion and marginally to the less-developed rural area of N. Kazantzakis. Taking account of the significant rural development policy investment that has taken place in Archanes in recent years, this finding raises doubts on the contribution of these policies towards the core EU policy-objective of cohesion.

Agricultural protection in industrialized countries and price distortions in developing countries are accused to hamper economic and agricultural development and are partly responsible for poverty and hunger in the Third World. A multi-commodity multi-country comparative static trade model is used to simulate the impact of different policy scenarios in this typical second best world for the case of South Africa.

Special emphasis is given to the disincentive effect of production and to endogenous policy responses in South Africa. In conclusion South Africa could benefit a lot by liberalizing trade and agricultural policies world wide, although it is an importer for most of the considered commodities.

In order to understand the future of food supply and demand and food security, it is essential to focus on the long-term, fundamental drivers, such as income and population growth, and technological change in agriculture as influenced by investments in agricultural research, irrigation, and other factors.

In the remainder of this paper we take a new look into the future role of agricultural research and technology development in world food markets based on alternative scenario simulations with IFPRI’s IMPACT model. The paper starts out by very briefly describing the model, and then presents and discusses alternative scenarios with a focus on the role of technological change.

In this paper we report on preliminary results of a research aimed to examine the content of farm animal biodiversity conservation actions currently under implementation in the European Union in the framework of EU Agenda 2000. In particular, we surveyed sixty-three Rural Development Plans (RDPs) set up in twelve countries in application of EEC regulations 1257/99 and 1750/99. Our analysis focused on endangered breeds of six major livestock species included in the RDPs. This analysis, which is based on the comparison with the indicator’s status of the DAD-IS FAO database, allowed to identify priorities in conservation efforts in each country, and estimate the level of expected public expenditure needed to ensure the moving of breeds from at-risk (of extinction) status to not-at-risk status over the period 2000-2006.

As biotechnology evolves new methods of genetic engineering are now being applied to the production and processing of foods. This paper is trying to explore the attitudes of the European consumers towards genetic modification of food. Using survey data of the EU member countries the proposed research paper is planned to have a threefold output: 1) providing a comparative ranking of the EU member countries in relation to the prevalence of rejection of genetically modified food, 2) uncovering intra-european differences in genetic food engineering rejection as being based on socio-demographic and informational resp. knowledge based differentials between EU countries and 3) specifying the importance of socio-economic and informational determinants of a potential defender of genetically modified food by estimating the partial effects of age, gender, education, income, family status, size of household, knowledge on genetical food engineering and information use behavior in a multivariate model of the attitudes towards genetically modified food. This causal approach will be followed in selected EU countries representing extreme positions in the EU attitude ranking. By these empirical results the paper is trying to reveal intra-EU differentials of consumer attitudes towards genetically modified food, which is a necessary baseline for adequate and efficient policies in order to satisfy consumer needs for quality and security. The results will also prove helpful to the food industry providing differential information for marketing decisions and focusing adjustments in different EU food markets.
