Selected AbstractsAgrifood Sector Liberalisation and the Rise of Supermarkets in Former State-controlled Economies: A Comparative OverviewDEVELOPMENT POLICY REVIEW, Issue 5 2004Thomas Reardon Former state-controlled economies (FSCEs) have become the most important destination of global retail chain investments. These economies, which spread from North Africa, across Central and Eastern Europe, to East Asia, include more than one and a half billion consumers and a large share of the world's agricultural area and poor farmers. They have undergone an often radical transformation of their agrifood system over the past decade. The take-off of supermarkets in FSCEs started seriously in the mid-late 1990s, and is now moving fast. This article compares FSCE experience in the supermarket revolution and considers its implications for policy-makers and rural development practitioners. [source] THE POPULATION GENETICS OF ADAPTATION: THE ADAPTATION OF DNA SEQUENCESEVOLUTION, Issue 7 2002H. Allen Orr Abstract I describe several patterns characterizing the genetics of adaptation at the DNA level. Following Gillespie (1983, 1984, 1991), I consider a population presently fixed for the ith best allele at a locus and study the sequential substitution of favorable mutations that results in fixation of the fittest DNA sequence locally available. Given a wild type sequence that is less than optimal, I derive the fitness rank of the next allele typically fixed by natural selection as well as the mean and variance of the jump in fitness that results when natural selection drives a substitution. Looking over the whole series of substitutions required to reach the best allele, I show that the mean fitness jumps occurring throughout an adaptive walk are constrained to a twofold window of values, assuming only that adaptation begins from a reasonably fit allele. I also show that the first substitution and the substitution of largest effect account for a large share of the total fitness increase during adaptation. I further show that the distribution of selection coefficients fixed throughout such an adaptive walk is exponential (ignoring mutations of small effect), a finding reminiscent of that seen in Fisher's geometric model of adaptation. Last, I show that adaptation by natural selection behaves in several respects as the average of two idealized forms of adaptation, perfect and random. [source] Reflections on and alternatives to WHO's fairness of financial contribution indexHEALTH ECONOMICS, Issue 2 2002*Article first published online: 28 FEB 200, Adam Wagstaff Abstract In its 2000 World Health Report (WHR), the World Health Organization argues that a key dimension of a health system's performance is the fairness of its financing system. This paper provides a critical assessment of the index of fairness of financial contribution (FFC) proposed in the WHR. It shows that the index cannot discriminate between health financing systems that are regressive and those that are progressive, and cannot discriminate between horizontal inequity on the one hand, and progressivity and regressivity on the other. The paper compares the WHO index to an alternative and more illuminating approach developed in the income redistribution literature in the early 1990s and used in the late 1990s to study the fairness of various OECD countries' health financing systems. It ends with an illustrative empirical comparison of the two approaches using data on out-of-pocket payments for health services in Vietnam for two years , 1993 and 1998. This analysis is of some interest in its own right, given the large share of health spending from out-of-pocket payments in Vietnam, and the changes in fees and drug prices over the 1990s.

[source] Information sources used by older adults for decision making about tourist and travel destinationsINTERNATIONAL JOURNAL OF CONSUMER STUDIES, Issue 5 2007Ian Patterson Abstract Over the past decade, the older market has emerged as an extremely important one because of its increased purchasing power for most consumer goods and services. The tourism and leisure industry is also targeting people aged 65 years and older, because many possess a relatively large share of discretionary money that they want to spend on travel. This has resulted in increasing attention by the mass media and the advertising industry in particular. This paper discusses the main types of information sources that are used by older adults when they make decisions about tourist and travel destinations, and particularly focuses on the importance of word-of-mouth sources and personal experiences. It also explores the influence of the mass media on trip decision making for older adults, and discusses the importance of brochures, magazines and television as information sources for older adults. Finally, it critiques the lack of senior models in advertising campaigns for travel products that are aimed at the older market. [source] Stopping antipsychotic drug therapy in demented nursing home patients: a randomized, placebo-controlled study,,The Bergen District Nursing Home Study (BEDNURS)INTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 9 2008Sabine Ruths Abstract Background Despite modest efficacy, unpredictable individual utility, and a high rate of adverse effects, behavioural and psychological symptoms of dementia (BPSD) are common determinants for antipsychotic drug therapy in nursing home patients. Aims To explore the impact on BPSD of stopping long-term antipsychotic treatment in nursing home patients with dementia. Methods Fifty-five patients (43 women; mean age 84.1) taking haloperidol, risperidone, or olanzapine for BPSD were randomly assigned to cessation (intervention group, n,=,27) or continued treatment with antipsychotic drugs (reference group, n,=,28) for 4 consecutive weeks. The Neuropsychiatric Inventory (NPI) Questionnaire was used to examine changes in behavioural and psychological symptoms. Results By study completion, 23 of the 27 intervention group patients were still off antipsychotics. Symptom scores (NPI) remained stable or even improved in 42 patients (intervention group, 18 out of 27; reference group, 24 out of 28; p,=,0.18). As compared to patients with stable or improved symptom scores, patients with behavioural deterioration after antipsychotic cessation used higher daily drug doses at baseline (p,=,0.42). Conclusion A large share of elderly nursing home patients on long-term treatment with antipsychotics for BPSD, do well without this treatment. Standardized symptom evaluations and drug cessation attempts should therefore be undertaken at regular intervals. Copyright © 2008 John Wiley & Sons, Ltd. [source] Issues in pension system designINTERNATIONAL SOCIAL SECURITY REVIEW, Issue 1 2002Maria Augusztinovics External conditions for pension system design and demographic and labour market trends are briefly considered and the latter found decisive. Basic concepts, e.g. social assistance and insurance, redistribution and actuarial fairness, are then introduced. Then it is argued that the "public PAYG versus private funded" dichotomy has attracted an unduly large share of attention in recent pension reform debates, as such institutional changes do not really address the basic problems, while quantitative aspects, the relationship between contribution and replacement rates, have been improperly neglected or shielded by the paradigmatic controversy. The next, crucial point is that traditional, employment-based, earnings-related forms of pension insurance are endangered by new trends on the labour market; hence, new solutions will have to be sought to ensure pension coverage for the entire population. A brief plea for more, relevant and comparative information on pension issues follows. The paper concludes with a concise summary and by contemplating what could and should be expected from the Second World Assembly on Ageing. [source] Decomposing the Value of Agricultural Multifunctionality: Combining Contingent Valuation and the Analytical Hierarchy ProcessJOURNAL OF AGRICULTURAL ECONOMICS, Issue 2 2007Zein Kallas Q18; Q11; Q25 Abstract Agricultural multifunctionality is the recognition of the joint exercise of economic, environmental and social functions by this sector. Nevertheless, not all these contributions to society are valued in markets, moreover a large share of them are public goods. For this reason, in order to make this concept of multifunctionality operative for the design of public policies, it is necessary to estimate the social demand of such functions. The objective of this article was to implement an empirical application along these lines. For this purpose, the agricultural system of cereal steppes in Tierra de Campos in Spain is taken as a case study. The economic valuation technique used relies on a combined implementation of contingent valuation and the analytical hierarchy process. The results obtained demonstrate the existence of a significant demand for the different attributes included in the multifunctionality concept, although this demand is heterogeneous and is based on the socioeconomic characteristics of individual persons. [source] Strategic Groups of EU Food ManufacturersJOURNAL OF AGRICULTURAL ECONOMICS, Issue 1 2000W. Bruce Traill Strategic groups of food manufacturers are derived using factor and cluster analysis applied to a survey of European food manufacturers. The aim is to obtain groupings of businesses that are meaningful for industry and policy analysis. Eight strategic groups are derived and profiled. The sources of competitive advantage of the businesses in the eight groups are assessed in relation to expected developments in the European food industry and the implications for industry and policy analysis are introduced. For example, businesses that have developed competencies in international sales linked either to product or process innovation appear better placed than those relying on local or national brand strategies. Countries with a large share of the former types of firms (e.g., Denmark) are better placed than countries with a large share of the latter types (e.g., Finland). [source] Environmental Impacts of Consumption in the European Union:High-Resolution Input-Output Tables with Detailed Environmental ExtensionsJOURNAL OF INDUSTRIAL ECOLOGY, Issue 3 2006Gjalt Huppes Summary For developing product policy, insight into the environmental effects of products is required. But available life-cycle assessment studies (LCAs) are hardly comparable between different products and do not cover total consumption. Input-output analysis with environmental extensions (EEIOA) of full consumption is not available for the European Union. Available country studies have a low sector resolution and a limited number of environmental extensions. This study fills the gap between detailed LCA and low-resolution EEIOA, specifying the environmental effects of household consumption in the European Union, discerning nearly 500 sectors, while specifying a large number of environmental extensions. Added to the production sectors are a number of consumption activities with direct emissions, such as automobile driving, cooking and heating, and a number of postconsumer waste management sectors. The data for Europe have been constructed by using the sparse available and coarse economic and environmental data on European countries and adding technological detail mainly based on data from the United States. A small number of products score high on environmental impact per Euro and also have a substantial share of overall consumer expenditure. Several meat and dairy products, household heating, and car driving thus have a large share of the total environmental impact. Due to their sales volume, however, products with a medium or low environmental score per Euro may also have a substantial impact. This is the case with bars and restaurants, clothing, residential construction, and even a service such as telecommunications. The limitations in real European data made heroic assumptions necessary to operationalize the model. One conclusion, therefore, is that provision of data in Europe urgently needs to be improved, at least to the level of sector detail currently available for the United States and Japan. [source] The Geopolitics of Natural Gas in AsiaOPEC ENERGY REVIEW, Issue 3 2001Gawdat Bahgat Over the last few years, natural gas has been the fastest-growing component of primary world energy consumption. This study seeks to examine the recent efforts by the Islamic Republic of Iran, Qatar, the United Arab Emirates and Saudi Arabia to develop their natural gas resources and capture a large share of the Asian market, particularly in Turkey, India, China, Japan and South Korea. Counter-efforts by rivals, such as the Russian Federation and the Caspian Basin states, are analysed. Finally, international ventures to transport natural gas from producers to consumers, including the Dolphin Project, the Trans-Caspian Pipeline and Blue Stream, are discussed. [source] Job and residential search behaviour of two-earner households,PAPERS IN REGIONAL SCIENCE, Issue 4 2000Jos van Ommeren Two-earner households; job mobility; residential mobility; commuting; search Abstract Even though a large share of the workforce belongs to two-earner households, job search models invariably ignore the interaction between the wage earners of the same household. In this article, job and residential search behaviour of two-earner households are simultaneously analysed. The main finding of the theoretical model is that two-earner households search less intensively in the housing market, and more intensively in the labour market, if the distance between the workplaces of the two wage earners is longer. In the empirical part the latter finding has been analysed based upon a data set for Dutch two-earner households. [source] The European Commission on Factors Influencing Labor MigrationPOPULATION AND DEVELOPMENT REVIEW, Issue 2 2001Article first published online: 27 JAN 200 A controversial issue in discussions on enlargement of the European Union beyond its existing membership of 15 countries is the migration flows that admission of new members could generate. Given major differences in income and wage levels between the EU states and the candidates for membership, casual theorizing suggests that the potential for massive international migration is very high. The fact that such migration has thus far been of modest size by most plausible criteria is attributed to the restrictive policies of the potential destination countries, policies that reflect national interests, in particular protection of labor markets, as perceived by voting majorities. With accession to membership in the EU this factor is removed: a cardinal principle of the Union, established by treaty, is the free movement of persons, including persons seeking gainful employment. The factors governing migratory movements between member states then come to resemble those that shape internal migration. This should facilitate analysis and forecasting. A clear sorting-out of the relevant forces affecting such "internal" migration remains of course an essential precondition for success in that task. An "Information note," entitled The Free Movement of Workers in the Context of Enlargement, issued by the European Commission, the EU's Executive Body, on 6 March 2001, presents extensive discussion of relevant information, opinion, and policy options concerning its topic. (The document is available at «http://europa.eu.int/comm/enlarge-ment/docs/pdf/migration_enl.pdf».) An Annex to the document. Factors Influencing Labour Movement, is a lucid enumeration of the factors migration theory considers operative in determining the migration of workers and, by extension, of people at large, that is likely to ensue upon EU enlargement. This annex is reproduced below. As is evident from the catalog of factors and their likely complex interactions, making quantitative forecasts of future migration flows, envisaged primarily as originating from countries to be newly admitted to the EU and destined for the countries of the current EU15, is exceedingly difficult. This is reflected in disparities among the existing studies that have made such forecasts. Yet there appears to be a fair degree of agreement that major increases in migration are unlikely, suggesting that the overall effect on the EU15 labor market should be limited. Typical forecasts (detailed in the Information note cited above) anticipate that in the initial year after admission, taken to be 2003, total migration from the eight prime candidate countries (the Czech Republic, Hungary, Poland, Slovakia, Slovenia, Estonia, Latvia, and Lithuania: the "CC8") might amount to around 200,000 persons, roughly one-third of which would be labor migration. According to these forecasts, the annual flow will gradually diminish in subsequent years. After 10 to 15 years the stock of CC8 migrants in the EU15 might be on the order of 1.8 to 2.7 million. The longer-run migration potential from the candidate countries would be on the order of 1 percent of the present EU population, currently some 375 million. (The combined current population of the CC8 is 74 million.) Such predictions are in line with the relatively minor migratory movements that followed earlier admissions to the EU of countries with then markedly lower per capita incomes, such as Spain and Portugal. The geographic impact of migration ensuing from enlargement would, however, be highly uneven, with Germany and Austria absorbing a disproportionately large share. Accordingly, and reflecting a prevailing expectation in these two countries that enlargement would have some short-run disruptive effects on labor markets, some of the policy options discussed envisage a period of transition following enlargement,perhaps five to seven years,during which migration would remain subject to agreed-upon restrictions. [source] Aid, debt and fiscal policies in SenegalJOURNAL OF INTERNATIONAL DEVELOPMENT, Issue 8 2006Bazoumana Ouattara Abstract This paper uses the fiscal response framework to study the effects of aid flows on key fiscal aggregates in Senegal, over the period of 1970,2000. Attention is given to the interplay between aid and debt. The paper contributes to the empirics of fiscal response modelling by deriving the standard errors and p values associated with the different mechanisms of the structural and reduced form equations. The main findings in this paper are: (i) relatively large shares of government resources are used to finance debt servicing; (ii) the impact of aid flows on domestic expenditure is statistically insignificant and (iii) debt servicing has a significant negative effect on domestic expenditure. The main policy implication of this study is that debt reduction could be a more effective policy tool than additional aid (loans) in financing pro-poverty expenditure as well as public investment.

[source] PLACE-BASED AND RACE-BASED EXCLUSION FROM MORTGAGE LOANS: EVIDENCE FROM THREE CITIES IN THE NETHERLANDSJOURNAL OF URBAN AFFAIRS, Issue 1 2007MANUEL B. AALBERS ABSTRACT:,Do place and race matter in mortgage loan applications? This article presents evidence from mortgage markets in the Dutch cities of Arnhem, The Hague, and Rotterdam, suggesting that place, and to a lesser extent also race, do matter. In general, race and place are not factors of direct exclusion, but (1) zip codes are included in credit scoring systems, and (2) both place and race are significant factors in the assessments by loan officers because applicants who do not meet all formal criteria are more often accepted ("overrides") for indigenous Dutch and low-risk neighborhoods than for ethnic minorities and high-risk neighborhoods. In addition, a "national mortgage guarantee" is compulsory for loan applications in high-risk neighborhoods and thereby used as a substitute for redlining, comparable to the compulsoriness of private mortgage insurance in the United States. Some lenders also engage in direct redlining by rejecting low-risk "national mortgage guarantee" loans in high-risk neighborhoods, a practice potentially explained by transaction cost economizing. Since the high-risk neighborhoods in all three cities accommodate relatively large shares of ethnic minority groups, they are hit twice: through place-based and through race-based exclusion. In other words, place-based disparate treatment results in race-based disparate impact. The neighborhood does matter; place-based exclusion in the mortgage market has a neighborhood effect.
