Subsistence agriculture in Central and Eastern Europe (CEE) has only recently gained interest from agricultural economists. Their origin, their future and even their definition is still not well elaborated. This paper tries to throw light on the issue of subsistence farming in CEE. It first discusses the theoretical and empirical background of subsistence agriculture. This part is followed by a typology of subsistence farming as found in CEE. Analysis considers several hypotheses on the cause of subsistence agriculture, among them the structure of land ownership, market imperfections and lack of alternative income sources or low opportunity costs of labour respectively. Of all these hypotheses, only the latter can be proofed empirically, which is done by a nonlinear regression analysis. The paper concludes that this gives reason to argue that rather economic problems than specific problems related to the agricultural structure in CEE determine the degree of subsistence farming. Consequently, structural and social policies rather than agricultural policies like market intervention are to be considered.

Regulatory reform had its beginnings in the United States in the 1970s, and today it is taking place around the globe. One of the central questions for industrial policy is how to regulate firms with market power. Regulatory Reform tackles this important policy issue in two parts: it describes an analytical framework for studying the main issues in regulatory reform, and then applies the analysis to the British experience in four utility industries - telecommunications, gas, electricity, and water supply. Britain's utility industries, state-owned monopolies just ten years ago, offer a dramatic example of comprehensive reforms with parallels elsewhere: industries have been restructured, markets have been liberalized, and new regulatory methods and institutions have been created. The authors focus on common policy questions that arise in each industry while taking into account the considerable diversity between the industries and the different reform policies adopted. The analysis and experience in Britain's utility industries also provides a rich variety of issues concerning monopolistic and anticompetitive practices that are of interest for competition policy in general.

Enlarging the EU presents a tremendous effort with obstacles for old and new member states especially in the agricultural sector. In this paper, impacts of a new accession round were analyzed with the help of the comparative-static general equilibrium model GTAP (Global Trade Analysis Project). The standard version was extended to allow for a better representation of specific instruments of the Common Agriculture Policy and the EU budget.

To capture detailed effects in new member states, simulations were carried out for 12 candidate countries, the EU-15 and the rest of the world. As for products the focus lies on agriculture. Scenarios include an enlargement with and without the transfer of direct payments in the new member states, according to the proposal of the EU commission from January 2002. Simulations in a post-Agenda 2000 environment led to heterogeneous country specific impacts in the accession countries whereas the changes within EU-15 and the rest of the world were negligible. Due to adjustments in tariffs, trade balances of the new member states were deteriorating while welfare effects are positive. Transfer of direct payments led to more pronounced effects, especially with regard to output and trade. Without direct payments accession countries would be net contributors to the EU budget. This would change when they become eligible for this subsidy. In general, the analysis shows the importance of a country specific perspective.

Migrant networks, in the form of families, associational ties and social organizations, stretch across the globe, connecting cultures and bridging national boundaries. The effects of this global networking are vast. This book is the first to stand back and explore the impact. Families living outside of their original national boundaries have had, and continue to have, a profound influence over the flow of people, goods, money and information. More in-depth perspectives reveal how immigrants face troubling issues of cultural identity, economic change, political uncertainty and social welfare. From an examination of nineteenth-century transnational families emigrating from Europe, to the Ghanaian Pentecostal diaspora in Europe today, this book combines broadly based analysis with more unusual case studies to reveal the complexities that immigrants and refugees must contend with in their daily lives. What are the experiences of migrant Turkish women living in Germany? In what ways has religion been hybridized amongst West African Muslim migrants in Paris? What are the gender relations and transnational ties amongst Bosnian refugees? Never has such a topic been more relevant. Problems relating to immigrants' and refugees' situations in their adopted countries continue to grow. This book, wide-ranging in its geographical and thematic scope, is a highly important and timely addition to debates on transnational families, immigrants and refugees.

Commercial producers, brokers, exporters and spinners dominate the wool supply chain in South Africa. Until recently smallholder farmers in the Transkei region had limited access to a profitable market outlet for their wool. In response, the South African wool industry has taken the initiative to help local farmers by building shearing sheds, under which the local association can bulk the wool and trade directly with the brokers. More direct access to the wool brokers is a prerequisite for the farmer to develop a viable business.

This article investigates on the effect of membership in the local shearing shed association on the farmers. revenue. A two-step regression model of the gross margin is used to analyse whether farmers selling through the local association have better financial records as compared to those who sell their wool to local traders. This article exemplifies how institutional innovation through local marketing associations can contribute to economic development in poor rural areas.

This paper examines the factors influencing farmers' participation in several agri-environmental schemes. A multinominal logit model is used to separate between participating and nonparticipating farmers. In addition this model allows to predict farmers participation in one measure as well as in different measures simultaneously. Data stems from a survey conducted in eight European countries and includes a description of both farmer and farm characteristics. Three categories of schemes have been analysed: landscape maintenance, biodiversity protection and restriction of intensive farming practices. The combination of these three types of schemes provides eight possible packages which can be selected by eligible farmers.

The multinominal logit model shows the importance of both farm and farmer as well as attitudinal characteristics on the participation in different combinations of schemes. For instance, the environmental concern favours landscape maintenance and biodiversity protection as well as their combinations with schemes requiring restrictions of intensive practices. However, it has a negative effect on the single participation in schemes requiring restrictions of intensive practices only. Our analysis confirms a number of previous findings. In addition, it shows the importance for policy makers to take into account that farmers have the opportunity to enter several schemes simultaneously. Indeed, due to cost complementarities, joint participation provides both private and public benefits.

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.

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 new method for analysing environmental efficiency, based on the materials balance, is proposed. With this method, an environmental allocative efficiency measure can be defined analogously to the more commonly used economic allocative efficiency. Nutrient surplus in pig fattening, a typical balance indicator, is used to illustrate the concept in a two input - one output case. The materials balance based efficiency analysis is elaborated using data envelopment analysis (DEA). Results are compared with those of more common, merely input or output oriented DEA approaches. A main conclusion is that, ignoring the balance feature of environmental issues such as nutrient surplus might be a main reason why traditional integral analyses of economic and environmental efficiency yield contradictory conclusions.

When public goods are joint outputs of agricultural production, there is a trade-off between agricultural and non-agricultural provision of the public good. The principle of minimal price distortion in the reform of agricultural policies has led to a theoretical recommendation that public goods, if under-provided at agricultural free market level, should be promoted through non agricultural policies instead of agricultural policies. We show that the economies of scope between the agricultural production and the joint public good play a key role in determining the optimal way of providing this latter. If the policy designed is a non- agricultural policy, the production cost of the public good is higher than with an agricultural policy. If the policy designed is an agricultural policy, the production cost is lower but generates market effects. Under the assumption of strictly positive economies of scope, we show that the optimal policy is a mix of agricultural and non-agricultural policy. We confirm this result in the two-country case, demonstrating the optimal level of agricultural support for public good provision is strictly positive and lower than in the case of one country.

The interactions of water policies and agricultural policies are increasingly determinant for achieving an efficient management of water resources in many countries. In the EU, agricultural and environmental policies are seeking to converge progressively towards mutually compatible objectives and, in this context, the recently reformed Common agricultural Policy (Agenda 2000) and the EU Water Framework Directive constitute the policy framework in which irrigated agriculture and hence water use will evolve. In fact, one of the measures of the European Water Directive is to establish a water pricing policy for improving water use and attaining a more efficient water allocation. The aim of this research is to investigate the irrigators. responses to these changing policy developments in a self-managed irrigation district in Southern Spain. For this purpose, we have developed a stochastic programming model that estimates the farmers. responses to the application of water pricing policies in different agricultural policies scenarios when water availability is subject to varying climate conditions and water storage capacity in the district.s reservoir. Results show that irrigators are price-responsive but a similar water-pricing policy could have distinct effects on water use, farmers. income and collected revenue by the water authority in different agricultural policy options. Water availability is a determinant factor and pricing policies are less effective for reducing water consumption in drought years. Thus, there is a need to integrate the objectives of Water Policies within the objectives of the CAP programs to avoid distortion effects and to seek a synergy between these two policies.

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.
