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.

We describe how an applied dynamic general equilibrium model of the Danish economy has been developed to generate structural forecasts. The forecasts provide a microeconomic picture that is consistent with a macroeconomic scenario and the other inputs. We provide an overview of the inputs required to generate the forecasts and of the forecast methodology. Finally, we present aspects of the forecasting results.

Адорно Теодор (1903 — 69) по праву считается одним из основоположников социологии музыки как самостоятельной научной дисциплины. Авторитету Адорно—социолога во многом способствовала деятельность Адорно—музыкального критика, принесшая ему заслуженную славу едва ли не самого яркого представителя музыкальной эссеистики XX в. Музыкально-социологические труды Адорно находятся, скорее, на перекрестье публицистики и социальной философии, нежели собственно социологии искусства. Будучи представителем леворадикального крыла европейских интеллектуалов и одновременно пропагандистом творчества композиторов новой венской школы (А. Шёнберга, А. Веберна, А. Берга — наиболее последовательных представителей австро-немецкого музыкального авангарда первой половины XX в.), Адорно, предлагая свою музыкально-социологическую концепцию, не скрывал личных эстетических пристрастий. Во многом это отразилось и на трактовке созданной им социологии музыки (Musiksoziologie), в значительно большей степени обязанной своим появлением лекционной и публицистической деятельности Адорно, нежели эмпирическим исследованиям.

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.

In this paper we use a general equilibrium model to examine the effects of international quota transfer when a quota restricts world commodity production whilst the trade in an intermediate good is not regulated. The analysis shows that, when the quota regime is not internationally transferable, intermediate input trade substitutes for final good trade. In these circumstances, the distortions are lower than expected. International quota transfer increases world welfare proportionally to quota rent gap. Welfare distribution is also conditioned by commodity terms of trade and, particularly, by the outcome of the intermediate good price.

This paper employed a robust stochastic efficiency decomposition technique that accounts for scale effects to derive the technical, allocative, and overall productive efficiency of two samples of farmers, participants and non-participants in the New Extension Program (NEP), in two agro-climatic zones in eastern Ethiopia. Using data for the 2001/2002 agricultural year, we find that both groups of farmers in the two zones have considerable overall productive inefficiencies. In the wet highlands, although the participants in NEP used a superior technology and have higher technical efficiencies, their allocative efficiencies turned out to be lower than the non-participant farmers, relative to their respective technologies. However, both groups exhibit similar productive efficiencies. In the dry lands, apart from using homogeneous production technologies, the two groups do not have significantly different technical and allocative efficiencies and that they have similar productive efficiencies.

Therefore, we find no empirical evidence of a positive impact of NEP on overall productive efficiency in both agro-climatic zones. An investigation of the influence of several socioeconomic and institutional factors revealed that education, credit, previous participation in extension programs, off-farm income and the share of the leading cropping system have a positive impact on efficiency.

The methodology used for Economic Valuation of the Externalities generated by the Watershead Restoration and Erosion Control Projects in the Hydrographic Basins of the Mediterranean Slope, is based on the Replacement Cost Method. Environmental Economics, however, today offer us other methodological possibilities, whose application to the valuation of this type of project may prove to be of interest. It is the case of the Contingent Valuation Method used for the evaluation of the effects of the Watershead Restoration and Erosion Control Projects of the Aljibe Basin (Almería) Spain, presented here. The results obtained show that, in this case study, application of Contingent Valuation ascribes greater social profitability of the project, with 5.23 % of IRR (Internal Rate of Return), compared to the value obtained using classic methodology of 2.25%, thus enabling us to draw closer to the true socio-environmental value of this type of project. In any case, both possibilities rather than alternatives can be considered as complementary, by focusing on the valuation from different perspectives.

Estimated rates of return to research are distorted by problems of attributing the credit for particular research results, or for particular research-induced productivity increases, to research expenditures undertaken at different times, in different places, and by different agencies. A comprehensive assessment of the evidence from past economic evaluations of the returns to agricultural R&D indicates that studies generally report high rates of return, with enormous variation among studies, but that much of this evidence has been tainted by inadequate attention to attribution problems. br>
This paper raises these concerns in a general way, and illustrates their importance with reference to two particular types of attribution problem. First, we consider the problem of accounting for locational spillovers in attributing varietal improvement technology among research performers, using U.S. wheat varieties as an example. Second, we consider the temporal aspects of the attribution problem using the specification of research lags in econometric models to illustrate the problem of attributing aggregate productivity gains to research expenditures at different times.

Many policy makers and businesses erroneously believe that rural populations, particularly in Africa, have no margin for savings over consumption needs. This study examines the potential for financial savings in rural Mozambican households by looking at the determinants of savings behavior. An econometric model for a household.s saving behavior was estimated using data from 113 rural households from Nampula province in Mozambique. Results indicate that income, physical wealth, household size, and years of schooling affect a household.s savings behavior. The study also finds that Mozambican rural households use their own grassroots associations for many financial services due to the lack of access to formal financial intermediaries.

The paper shows how analyses assuming perfect competition can yield a distorted estimation of the expected effects of a trade liberalization when market imperfections exist. The analytical framework adopted is very simple and three extreme imperfect market structures are considered. In the first case, the exporting country maximizes its producer and consumer surplus by intervening in the world market. The second market imperfection considered is the existence of a private firm playing the role of “pure middleman” in the world market. Then the case of a producer-owned marketing board which is granted exclusive export authority is addressed. It is shown that under all three scenarios, if perfect competition is assumed when market imperfections exist, the impact of a tariff reduction on prices and volume traded is overestimated. A ranking of the size of such distortions in the three cases analyzed is provided. Finally, it is proved that when a private firm exerts monopoly and monopsony power in the world market, both the importing and the exporting countries may well be better off if, rather than making a move towards trade liberalization, the importing country “compensates” the exporting country by means of a direct transfer.

The objective of this paper is twofold. First, we intend to show how regional impacts of the CAP can be measured in terms of the price and revenue impacts. Second, new empirical evidence will be presented by use of the proposed method for regions in Germany. Data utilized are available over time (1986-99) and across commodities, so that regional support due to the CAP can be aggregated from support for the individual commodities.

In todays competitive landscape organizational learning and knowledge management initiatives are emerging of powerful sources of competitive advantage. In this paper, the researches report on the design and expected result of a survey on knowledge management, which has been designed putting special emphasis on the interplay between the technical and non-technical aspects of learning and knowledge management initiatives. Questionnaires have been sent to 1100 firms from 11 industries in Spain, in order to be able to conduct both intra- and inter-industry analysis. In addition, in order to enrich the results, in-depth interviews was going to be held with selected companies. This allowed the authors to report on (1) what knowledge management initiatives was planned and carried out, (2) the role of technology in these initiatives, (3) the role of non-technical aspects like career planning and human resource policies, (4) the perceived effectiveness of the initiatives, and (5) the main underlying causal dynamics at work.

In this paper, the Spanish demand for food away from home is analysed. A panel data set is built and appropriate techniques for estimating limited dependent variable models have been applied. Results indicate that where there are zero expenditures, these are largely due to infrequency of purchase rather than to abstention or to economic reasons. Furthermore, important differences appear among households. On the one hand, those households whose head is a highly-educated person, male, young and living on a salary in a large town are more likely to purchase food away from home. On the other hand, increases in income only provokes more than proportional increases in expenditure for those households headed by an unschooled person, a female or a person older than 55 and also for those households with more than half of its members older than 60 years.
