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.

The objective of the paper is to develop a methodology for supporting the evaluation and design of agri-environmental schemes. The methodology is based on a combination of mathematical programming, contract theory and multicriteria analysis and is tested on a case study in Northern Italy. The methodology proposed can add insights into the policy design process, by taking consistently into account three issues often overlooked: the adaptation of cropping systems to the measures proposed; the diversity of compliance costs among farmers; the multidimensionality of the decision problem.

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.

Successful innovation depends on the development and integration of new knowledge in the innovation process. In order to successfully innovate, the firm will combine different innovation activities. In addition to doing own research and development, firms typically are engaged in the acquisition of knowledge on the technology market and cooperate actively in R&D with other firms and research organizations. In this paper the authors provide evidence on complementarity between different innovation activities. Using data from the Community Innovation Survey on Belgian manufacturing firms, the authors show that firms that are only engaged in a single innovation strategy, either internal R&D activities or sourcing technology externally, introduced fewer new or substantially improved products compared to firms which combine internal and external sourcing. This result is consistent with complementarity between own R&D and external technology sourcing activities. Furthermore, the authors show that the different innovation activities are strongly positively correlated and identify common drivers, resulting in the perceived complementarity between these innovation activities. An important finding is that a capacity to strategically protect intellectual property and a more basic R&D base which may serve as an absorptive capacity, are important common drivers for the different innovation activities.

This paper presents a comparative method (SICOM) to evaluate complex site conditions at the level of a Federal State (Brandenburg) and at different areal units. The methodology uses primary site conditions and provides the possibility to objectively compare and judge different ecological questions. Objects with heterogeneous content are pooled in comparison groups. Consideration of the main site characteristics allows a goal-oriented allocation of subsidies. The use of SICOM is demonstrated for the wind and water erosion risk assessment across different scales from Federal State down to a parcel of land. The “parcel” aggregation-level proves to be useful to assess the erosion risk. Larger scales are less useful in the assessment of subsidies policy with regard to erosion risk. SICOM is demonstrated to be suitable for comparing and assessing regional aspects more objectively.

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 addresses the question which factors influence a farmer in deciding to adopt an innovation. We differentiate between innovations that are new to the farmer, but already well established in the sector, innovations that are early in their process of diffusion, and innovations that are new to the farmer’s sector. We use an ordered probit approach to relate adoption behaviour to variables that capture characteristics of the farm (labour and financial resources and market position), of the business environment of the farm (type of production and market, degree of regulation) and of the farmer (access to information, capabilities, preferences). We use data on 865 Dutch farms and find that innovation adoption is positively related to labour resources, market position, access to information and past adoption behaviour, and negatively to solvency and the degree of market regulation.

Water management for irrigation requires suitable policy tools able to meet social objectives and private behaviour. The legal framework in the EU is today faced with the new water framework directive (60/2000), that sets up new criteria for water management, regulation and pricing. Among other things, the water framework directive introduces the principle of full cost recovery and the polluter pays principle for water users. For many areas of Italy, this may be a significant shift compared to present payment criteria, based on traditional rights, political prices, partial running cost coverage or others. The aim of this paper is to analyse the problem of water regulation in agriculture as applied to irrigation issues. This is made by setting up and testing a simulation model based on the integration of a mathematical decision making model at farm level and a principal agent model at the level of irrigation boards. The model allows to quantify water demand and the optimal regulation from the point of view of the policy maker. The results show major impacts of water availability and prices on farm income. The adoption of a mix of pricing instruments related at the same time to crop rotation, water consumption and pollution can significantly improve water policy efficacy.

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.

In Ethiopia, growth in cereal production is accompanied by a more than proportionate increase in the standard deviation of production. This study applies descriptive and variance decomposition procedures to determine the sources of increased instability in cereal production in order to show whether they are caused by policy changes. It was found that production instability was caused more by increased yield instability. Considering the fact that use of high-powered inputs is limited to a small number of farmers, production is at subsistence level and that farmers. responsiveness to policy changes is constrained by infrastructural and institutional constraints and by the existing land policy, instability in yield is predominantly attributed to weather variability.

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.

This paper considers vertical price relationships between wholesalers and retailers on five local maize markets in Benin. We show that if the common factor and the long-run disequilibrium error are not explicitly taken into account in testing the channel model, one can easily be wrong about how restrictions on the error-correction structure must be interpreted in terms of economic power in the channel. The empirical results show interesting differences between markets and reveal that retailers play a more prominent role in the price formation process than generally assumed in the literature. Retailers in the two major towns do not allow wholesalers to behave as vertical price leaders, but in the two larger rural centers, wholesalers involved in arbitrage among urban markets are able to influence price formation.

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.
