The regulation for the promotion of rural areas (Reg. (EC) No 1257/1999) and its subsequent regulation (Reg. (EC) No 1853/2003) serve as the basis for EU agricultural structural policy for the promotional period 2000 to 2006. Promotional areas established through the individual regulations such as agricultural development measures, measures to improve competitiveness and the previously accompanying measures of the agricultural reform in 1992, as well as compensatory allowences for disadvantaged areas, are initially consolidated in these two regulations. The Commission’s overall intention is to adjust the promotional areas in terms of time and content and thus to target promotional synergy. A further change in the promotional approach is that the nine promotional areas of the regulation are to be evaluated by independent evaluators according to a Commission designed European-wide evaluation grid (European Commission, 2000). The processing of the common evaluation questions is obligatory, should a question or part of the questionnaire not be answered, an explanation must be included (ibid., P. A-3). The Commission reserves the right to stop EU co-financing should the evaluation not meet its criteria. This paper places a focus on critical reflection about the evaluation grid required by the Commission with regard to its use in the evaluation process using the example of agri-environmental measures.
A PARTIAL EQUILIBRIUM MODEL OF THE BEEF AND DAIRY SECTOR IN ITALY UNDER IMPERFECT COMPETITION /доклад на 10 конгрессе ЕААЕ, Exploring Diversity in the European Agri-Food System, Zaragoza, Spain, 28-31 August 2002 [книги]

In this paper we present a partial equilibrium model for the bovine sector (beef and dairy) in Italy, which can be used for simulation and forecasting. The structure of the model follows the vertical chain of the beef and dairy sector, allowing trade of both agricultural raw materials and final products. Since the processing and retailing stage is characterised by an imperfectly competitive structure, the model accounts for market power in modeling the price transmission mechanism. This provides further insights on the vertical transmission of shocks, both at the final level (i.e. the BSE crisis) and at the farm level (i.e. agricultural policy reform).

ARE FARMERS COMPLETELY RATIONAL CONSUMERS AND DO THEY SUFFER FROM A BORROWING CONSTRAINT?: THE DUTCH CASE /доклад на 10 конгрессе ЕААЕ, Exploring Diversity in the European Agri-Food System, Zaragoza, Spain, 28-31 August 2002 [книги]

There is some confusion in the literature on the consumption behaviour of farmers. We try to clear up some of the issues surrounding this confusion by elaborating and testing a model. Euler equations have been derived from a constant relative risk aversion utility function for total consumption expenditure, household expenditure and other expenditure, which includes durable goods. According to a test of Euler equations, farm households are not simply optimising lifetime utility. Rather, these households follow simple consumption rules, strongly influenced by habit formation. In line with most of the literature, we find that farm households are not borrowing constrained in their consumption expenditures.
A Regional Impact Analysis of European Policies in Rural Areas /доклад на 87 семинаре ЕААЕ, Assessing Rural Development Policies of the CAP, Vienna, Austria, 21-23 April 2004 [книги]

The objective of this paper is to evaluate the overall impact produced by the application of European development policies for rural areas of the Italian Marche region for the period 2000-2003. Towards this aim, the input-output approach is adopted. A Marche regional I-O table is firstly constructed using a hybrid method. To evaluate the overall impact throughout the territory, two models are developed and applied recursively: an interregional I-O model and a gravity model. As for the former, sub-interregional I-O tables are constructed, where the regions under study are, on one hand, the functional area receiving funds and, on the other hand, the rest of the Marche region. The gravity model is instead used to allocate among the other areas the impact calculated for the rest of the region. To show how the impact is distributed among regional areas, a Geographical Information System is used. The paper concludes illustrating the main results in terms of overall impact generated by policy and providing some considerations related to policy effectiveness.

The paper outlines a new pluralistic method for analyzing, assessing and improving corporate governance structures in their traits relevant both for financial and for human capital providers. The framework seeks to enlarge the rather universalistic approach to governance structures ranking used in the economic (principal-agent) approach, introducing sensitiveness to some relevant contingencies. Among the contingencies, task complexity and innovativeness is supposed to matter, as well as the configuration of motivations and preferences of capital providers which are supposed not to be uniform but to be predictable in their main configurations. The framewok is design-oriented and aimed at improving corporate governance configurations in a generative way, based on the discovery of superior matches between the preferences of different cathegories of capital providers over governance mechanisms (rather than focused, as usual, on the comparative assessment of discrete realized models). The approach is relational in two ways: it builds governance structures on pairwise analyses of effective matches among preference configurations; it builds governance structures as nexuses of complementary governance mechanisms (effective matches among mechanisms).
ARE THE POOR TOO POOR TO DEMAND HEALTH INSURANCE? / доклад на 25 конференции IAAE, Reshaping Agriculture’s Contribution to Society, International Convention Centre, Durban, South Africa, 16-23 August 2003 [книги]

Community based micro insurance has aroused much interest and hope in meeting health care challenges facing the poor. In this paper we explore how institutional rigidities such as credit constraint impinge on demand for health insurance and how insurance could potentially prevent poor households from falling into poverty trap. In this setting, we argue that the appropriate public intervention in generating demand for insurance is not to subsidise premium but to remove these rigidities (easing credit constraint in the present context).
Thus from insurance perspective as well, our analysis highlights the importance of having appropriate savings and borrowing instruments for the poor.

A REVIVAL OF LARGE FARMS IN EASTERN EUROPE? HOW IMPORTANT ARE INSTITUTIONS? / доклад на 25 конференции IAAE, Reshaping Agriculture’s Contribution to Society, International Convention Centre, Durban, South Africa, 16-23 August 2003 [книги]

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.
Assesing the Perspectives of EU Cotton Farming: Technical and Scale Efficiencies of Greek Cotton Growers /доклад на 10 конгрессе ЕААЕ, Exploring Diversity in the European Agri-Food System, Zaragoza, Spain, 28-31 August 2002 [книги]

Utilizing the stochastic frontier approach, this paper estimates output and input-oriented technical and scale efficiency levels for a sample of cotton-growing farms in Thessaly, Greece. The empirical results suggest that Greek cotton farm operations are technically and scale inefficient. There is a considerable scope for improvement in resource use and thereby in farm income of cotton farms; Greek cotton farmers could reduce production costs by 20.4%, making more efficient utilization of the existing production technology. Factors responsible for the technical efficiency differentials observed among cotton-growers include the farmer’s age and education as well as the farm’s land fragmentation and output specialization.
ASSESSING ECONOMIC RETURNS FROM FARMERS’ RIGHT / доклад на 25 конференции IAAE, Reshaping Agriculture’s Contribution to Society, International Convention Centre, Durban, South Africa, 16-23 August 2003 [книги]

Many developing countries are attempting to address the inequities of plant breeders' rights by incorporating farmers' rights provisions in their Plant Variety Protection legislations to reward the role of farmers as conservers and enhancers of agro-biodiversity. Developing countries expect to generate substantial revenues for biodiversity conservation or for community reward schemes through the application of farmers' rights provisions. This paper applies a patent-renewal model to assess the economic returns appropriated by plant breeders from new (protected) varieties in developed countries. The estimates confirm a widely held view in the literature that plant variety protection is a relatively weak form of IPR protection which allows plant breeders to appropriate only limited returns from their innovations. Consequently, the application of farmers' rights provisions in a manner akin to breeders' rights is unlikely to be a source of significant revenue to developing countries.
Assessing the farm level impacts of yield and revenue insurance: an expected value-variance approach /доклад на 10 конгрессе ЕААЕ, Exploring Diversity in the European Agri-Food System, Zaragoza, Spain, 28-31 August 2002 [книги]

This paper investigates the farm level impacts of multiple peril yield and revenue insurance in an expected value-variance framework. The analysis is conducted using stochastic simulation jointly with numerical optimisation. Simulation is used to compute the means and variances of revenues as affected by the insurance schemes under consideration. In a second step these results are incorporated in a whole-farm programming approach, which optimises a portfolio that consists of crop production and insurance activities. The results of a case study indicate that from the farmer's point of view there is an incentive to buy multiple peril crop insurance, because it significantly reduces the variability of income. The risk reduction through insurance in turn leads to a specialisation of the production program. The farm level benefit of crop insurance strongly depends on the decision maker's degree of risk aversion. Furthermore, risk free parts of the total income reduce the economic attractiveness of insurance schemes. This applies e.g. to the area payments under the European agricultural policy, which therefore limit the potential demand for crop insurance.
Assessing the Structural Change of Strategic Mobility Determinants under Hybercompetitive Environments [книги]
Опубликовано на портале: 25-12-2002Jose Angel Zuniga Vicente, Jose David Vicente Lorente
In this exploratory study, the authors set out to develop and test a dynamic and integrative framework on strategic change. On the basis of theoretical arguments and prior empirical evidence from the adaptation and inertial perspectives, the researchers propose an original empirical model to examine whether potential determinants of strategic change remain stable over time in a hypercompetitive environment. The authors look for an answer to this question in the Spanish private bank industry during a period of high strategic mobility as consequence of continuous and drastic environmental transformations. The results strongly support that the effect of potential determinants of strategic mobility in this industry did not remain stable over the whole period of analysis. From this point of view, the study sheds new light on major debates and dilemmas in the field of strategy regarding why firms change theirs competitive patterns over time, and hence whether the adaptation and inertial views really must be considered as complementary perspectives. Furthermore, the paper introduces two important methodological innovations which facilitate future empirical replies. First, the definition and measurement of strategic change by employing a new grouping method, the MCLUST. Second, the control of the non-observable heterogeneity using panel data models for logit regression.
Assisting whole-farm decision-making through stochastic budgeting /доклад на 10 конгрессе ЕААЕ, Exploring Diversity in the European Agri-Food System, Zaragoza, Spain, 28-31 August 2002 [книги]

Stochastic budgeting is used to simulate the business and financial risk and the performance over a six-year planning horizon on a Norwegian dairy farm. A major difficulty with stochastic whole-farm budgeting lies in identifying and measuring dependency relationships between stochastic variables. Some methods to account for these stochastic dependencies are illustrated. The financial feasibility of different investment and management strategies is evaluated. In contrast with earlier studies with stochastic farm budgeting, the option aspect is included in the analysis.
