В книге даётся анализ, главным образом, институциональной структуры рынка, то есть структуры продовольственной цепи, ее эволюции, а также, частично, функции рынка и его эффективности. Отмечается, что центральной задачей российской аграрной реформы является переход от централизованно планируемой системы к рыночной. Это предполагает не только формирование рыночно ориентированных производителей непосредственно в самом сельском хозяйстве, но также и создание принципиально иной рыночной инфраструктуры, позволяющей эффективно перемещать продукт от поля к конечному потребителю, с одной стороны, и с другой – также эффективно доставлять рыночную информацию, сигналы от потребителя к производителю и обратно. Подчёркивается, что если проблема реорганизации сельскохозяйственных производителей в России изучена в отечественной и западной литературе достаточно хорошо, то проблема формирования российских агропродовольственных рынков остается крайне слабо исследованной. Подчёркивается также, что исследование рынков в классическом понимании традиционно включает в себя: анализ степени конкурентности рынка, институциональной и функциональной структуры рынка, условий рыночного равновесия и эффективности рынка.

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 examine the performance of the primary school education system in Tanzania over the 1990s - a decade characterized by substantial AIDS deaths. Given the relatively robust correlation between educational attainment and productivity established in the literature in both agricultural and non-agricultural sectors, human capital accumulation through education forms a major component of development strategy. At the same time, AIDS poses clear threats to the goal of human capital accumulation through education. To assess performance of the primary school system, we estimate non-stationary education transition matrices using a minimum cross entropy approach at the national, sub-national, and regional levels for girls, boys, and all students. Results indicate a deterioration in primary school performance using enrollments in grade 7, the final year of primary school, as a metric. This deterioration in performance occurred despite increased real resource allocations to the public education system and positive, if only tepid, overall economic growth trends. We conclude that the HIV/AIDS pandemic has quite likely slowed human capital accumulation in Tanzania.

Most of the large scale modeling systems used in the analysis of agricultural policies produce deterministic projections. In reality, however, the agricultural sector is subject to a high degree of uncertainty as a result of fluctuations in exogenous factors such as the weather or macroeconomic variation. A stochastic approach can provide additional information to policy makers regarding the implications of this uncertainty, through the use of stochastically generated projections.

This paper also shows how deterministic analysis may result in systematic errors in the projection of some variables. As an applied example, the FAPRI model of the US agricultural sector is simulated stochastically to analyse the impact of proposals for the new US farm bill.

In the Mid-Term Review (MTR), the European Commission proposed a series of changes to the Common Agricultural Policy (CAP). An important part of these changes was significant decoupling of support payments from production. In this paper, a partial equilibrium model of the EU agricultural sector is used to estimate the potential impacts of the MTR proposals on EU and world agricultural markets over the period 2004-2009. Effects of the MTR proposals are evaluated by comparing estimated outcomes under the proposals to those that would result under a current-policy baseline. The changes that are made in the MTR have the effect of reducing the production of the major commodities by varying amounts based on the importance of payments in production and the degree to which these payments are currently production inducing. For example, total area harvested for nine major crops falls by about 2 percent under the MTR proposals. In the livestock sector, however, where current payments are strongly coupled and form a large part of producers’ income, the reductions in production are projected to be more significant.

Theoretical and simulation results clarify the role of forward procurement contracting as a determinant of spot price levels and volatility. A stylized model determines market share across quality when procurers forward contract to manage quality risk. Actual supply is specified as price dependent and stochastic. Simulation examines sensitivity of spot price level and volatility to extent of forward contracting, risk aversion, and ability to adjust spot market demand (recontracting).

The results show that as forward contracting increases mean spot price decreases and variance increases. This effect increases as risk aversion decreases and as the extent of recontracting adjustment in spot demand decreases.

In Rwanda for the past decade, rural households have lived with civil unrest and genocide, changing land laws, large population flows both into and out of the country, and climatic threats with droughts and floods. The illness and untimely death of prime age adults from a number of health problems (increasingly HIV/AIDS) adds to the stress of these households and has lasting effects on the ability of households to survive. In this research, the authors use household and member level survey data to increase understanding about what is happening in households with such shocks and how they may be different from other Rwandan rural households.

This research finds that households affected by adult illness and death strive to maintain their agricultural production, and work to avoid selling assets, yet some households appear to be in a downward spiral, losing assets and income earning potential. They rely heavily on social networks for labor and skills, but clearly these networks will be stretched beyond their means in any continuing epidemics. Female-headed households in particular struggle to find labor with neighbors or work more themselves. If special programs are developed for the affected families, focusing on increasing land and labor productivity fits into their own strategies. Since households with prime age death and disease appear to be similar to other Rwandan households in the poorest two quintiles, such programs would be beneficial to rural households in general, and possibly strengthen social networks through generalized agricultural and income growth.

The paper analyzes the impact of different agricultural trade policies on Russia’s bilateral trade patterns, price and quantity changes, and welfare effects for producers, consumers, and the state budget. Three experiments are simulated using a partial equilibrium model based on the Armington approach. The results show that the current situation of import tariff-free trade between Russia and other CIS countries has small positive welfare effects for the Russian Federation in comparison to a situation where import tariffs between these countries were to be imposed.

However, according to the results, an elimination of import tariffs against all trading partners is preferable for Russia in terms of net welfare. An increase in discriminatory trade barriers against non-CIS countries would cause overall welfare losses for the Russian economy.

This study examines family farms and characteristics affecting farm succession. Based on a farm survey, three aspects of succession are analysed in the paper: the probability of family succession; the likelihood of having a successor designated; and the timing of succession. Large and specialised farms are more likely to be transferred within the family and to have appointed a successor. The number of family members, as well as the experience of farm operator, is also significantly related to the succession behaviour. The probabilities of succession, and of having a successor, first increase with age and then decline again. Furthermore, timing of succession is delayed as the farm holder ages, suggesting most farm operators’ succession plans to be inconsistent over time. In addition, we find a significant interrelationship between the different aspects of succession indicating that decisions on family succession, the designation of a successor, as well as the timing of succession, are not separable.

The paper introduces a general methodological approach for the estimation of constrained optimisation models in agricultural supply analysis. It is based on optimality conditions of the desired programming model and shows a conceptual advantage compared to Positive Mathematical Programming in the context of well posed estimation problems. Moreover, it closes the empirical and methodological gap between programming models and duality based functional models with explicit allocation of fixed factors. Monte Carlo simulations are performed with a maximum entropy estimator to evaluate the functionality of the approach as well as the impact of empirically relevant prior information in small sample situations.

The objective of the paper is to identify the determinants of access to health care in rural Russia. We started out with the observation that the transition process has affected the provision of social services in the Russian Federation in general, and in rural areas in particular, owing to the overlap with agricultural reforms. Based on this observation we asked how the reduced role of the state and the concomitant decentralization of policy making has affected access of the rural populace to social services. A review of the available literature on this topic resulted in the formulation of the following three hypotheses. Firstly, that income is a determinant of access to health care. Secondly, that informal payments play an important role in determining access, and thirdly that there are large differences in access to health care services between districts. The hypotheses were tested using household data from a survey conducted in two regions of Russia in 2000. The results indicate that in the study regions, contrary to expectations, neither income nor informal payments are important determinants of access. However, there are large differences in out-of-pocket expenditures between districts, indicating that access to health care varies between districts.

Retail pricing strategies incorporate promotions, sales, and rigidities. A number of models have been proposed in particular to explain the occurrence of sales. Focussing on the market for fresh foods the model by Varian and the loss leader argument seem to be intuitively best fitting to the conditions in the fresh food market.

From these models we derive several hypotheses that are tested for a unique data set of the German fresh food retail market. The data set consists of weekly prices for ten food items in 131 grocery shops over the period from 1995 to 2000. Following Varian sales should lead to reduced expenditures, while the loss leader argument assumes that consumers are lured into the shop by promotional sales which are covered by higher prices for other products. The results indicate that expenditures decrease with the number of sales in the short run but this effect is outweighed by a dynamic price adjustment thereafter.

Only a few studies have analysed staggering and synchronisation in pricing behaviour of multi-product firms. These studies used low-frequency data in an environment of high rates of inflation. This paper investigates staggering and synchronisation of weekly prices for ten food products in 131 grocery stores in Germany over the period from May 1995 to December 2000 (296 weeks). Different forms of staggering and synchronisation (across-store synchronisation, within type-of-store synchronisation, within retailer synchronisation or across-product synchronisation) have been analysed. None of these forms of synchronisation is supported empirically however. In contrast, perfect staggering can only be rejected in very few cases.

This article is based on a socio-economic impact study of the introduction and adoption of tissue-culture (tc) technology in banana production in Kenya. It attempts to demonstrate that a prudent introduction and promotion of a new biotechnological innovation in farming can make a positive contribution to the socio- economic status of resource poor farmers in a developing country, such as Kenya. Adoption of tc technology in banana production in Kenya is considered a good example of biotechnological applications in agriculture. Hence the article hopes to make a contribution to recent debates at international levels as to whether biotechnology can make a difference in uplifting the living standards of people in the third world (Qaim, 1999; Graff, et al 2002; Qaim, et al 2002) by showing that it actually does so, using experiences from Kenya. The study utilizes both primary and secondary data sources. The results show that tc-banana production is relatively more capital intensive than non-tc banana production (re: about 70% fixed costs for tc banana versus about 49% fixed costs for non-tc banana). However, tc-banana production is found to offer relatively much higher financial returns than non-tc banana production. The high profitability of tc-banana production relative to traditional (non-tc) banana production and other farm enterprises in the pilot tc-banana project area in Kenya demonstrates the importance of biotechnological applications in rural development and shows that biotechnology can make a difference in uplifting the living standards of people in the third world. Therefore, efforts to promote tc-banana production in Kenya are justifiable from both food security and economic criteria.
