Persistent and widespread poverty in less-favored areas (LFAs) is attributed to fragile natural resources and poor markets. Limited assets may keep households outside the reach of poverty policies targeted at LFAs. We explored in a stylized manner the role of heterogeneous household assets for (1) policies aimed at poverty reduction; (2) within-village income inequality; and (3) soil erosion. With a farm-household micro-simulation model we analyzed for each household in a remote Ethiopian village three sets of policies: technology improvement, infrastructure investment, and off-farm employment through migration or cash for work (CFW) programs. Combating poverty with a single policy, migratory off-farm employment reduces the poverty headcount most. Because of self-selection, CFW programs performed best in terms of reaching the poorest of the poor. CFW also reduced within-village income inequality most, while a price band reduction increased income inequality. Only technology improvements resulted in a trade-off between poverty and soil erosion. Price band and off-farm employment policies reduced erosion while outperforming technology improvements in terms of poverty reduction. We found that combining two policies was most helpful in assisting poorer households to overcome the limitations of their asset endowments. A CFW program combined with reduced price bands yielded most in terms of poverty reduction and income inequality. This policy complementarity is, however, less important for better-endowed households. Reducing the reliance of households on agriculture offered a win-win situation of reducing poverty and maintaining natural resources. Combining policies helped to overcome asset limitations, to target policies to the poorest households and to reduce income inequalities.  相似文献

The objective of this paper is to investigate the factors that influence distance traveled by individuals in Canadian urban areas, with a particular focus on three population segments thought to face the risk of mobility challenges: the elderly, low-income people, and members of single-parent households. Data obtained for three large urban centers - Hamilton, Toronto, and Montreal - are analyzed using spatial expansion models, a technique used to obtain spatially-varying coefficients that help to tease out contextual person-location variations in travel behavior. Detailed geographical results help to enhance our understanding of the spatiality of travel behavior of the population segments of interest. Substantively, the results provide evidence of significant interactions between location, various demographic factors, and mobility tools. More specifically, the results evince patterns of mobility that are significantly different from the mainstream population, particularly in suburban settings, in ways that are indicative of mobility challenges.  相似文献

To assess the educational performance gaps in Eastern Europe, this article takes a look at the differences in PISA test scores between Finland and seven Eastern European countries, as well as between Eastern European countries. The methodology applied is a semiparametric version of the threefold Blinder–Oaxaca decomposition. We find that main part of the average test score gap cannot be explained by the individual characteristics. Furthermore, our analysis at different quantiles provides evidence that the average test score gaps are due to the fact that poorly performing students in Finland score much higher than poorly performing students in Eastern Europe.  相似文献

This paper examines the provision of mobility options being one of the important policy areas vital to addressing transportation accessibility of the elderly. A provincial analysis, taking the case of the Province of Ontario in Canada, is warranted given that the country’s highly decentralized system puts provincial policies at the forefront in meeting this challenge. The paper evaluates the important progress made in this policy area and stressed the need to go beyond the traditional policy focus on the less able-bodied elderly and consider the increased heterogeneity of the elderly population with respect to lifestyle, preferences, resources, health and physical abilities. While significant efforts have been made, a more explicit recognition of population aging in Ontario’s transport policy motivation that could strongly influence transport strategies and investments attuned to the mobility concerns in an aging society remains to be seen. The paper summarizes the general concerns in the literature, policy developments, and the challenges in crafting solutions in terms of policy and research for Ontario and other regions with similar institutional setup.  相似文献

This a programmatic paper with all of the frustrations thereof [1]. We point beyond the well-tilled ground of foresight as commonly practiced (called Foresight 1.0) to an emerging understanding of the work and character of foresight (called Foresight 2.0). By definition, as of today, this new territory is not well mapped, much less carefully worked-over. The question that drives this commitment to Foresight 2.0 was the heart of the 2007 Strathclyde Organizational Foresight Conference—Learning the Future Faster: “Can foresight as commonly practiced enable us to learn the future fast enough to meet and deal with the unique strategic challenges of the 21st Century?” The view taken is that Foresight 1.0 cannot meet this challenge; that it leads to small victories and major disasters. An explanation is offered: Foresight 1.0 was developed, and is still largely practiced, with the eyes and mind of management, whereas sustained success in the unique conditions of the 21st Century requires Foresight 2.0—seeing, thinking and acting with the eyes and mind of Leadership. This distinction is explained. Evidence is offered that futures research and foresight are slowly moving towards this new practice. The hope is expressed that, if we grasp the need for it, the nature of it and have explicit mental maps of the journey to it, we who are professional foresight researchers and practitioners will move faster and more effectively to develop Foresight 2.0. Several steps towards this end are outlined.  相似文献

The objective of this study is to investigate the determinants of mean trip distance traveled by different mode types. The study uses data from the Hamilton CMA in Canada, and multilevel models to investigate the variables that impact distance traveled, with a specific focus on demographic aging factors. The results of the study validate previous findings regarding the decline in distance traveled as age advances. In addition, it is found that: (1) while this effect of age is present for all modes analyzed (car driving, car passenger, and bus) it is considerably more marked for car driving; (2) there are significant effects compounded by the interrelated factors of gender, employment constraints, household contextual factors; and (3) neighbourhoods with high commercial and residential mix showed a negative relation with distance traveled only in the case of car driver.  相似文献

Abstract

In this article, we analyze opportunities and constraints for upgrading product quality in the dairy value chain in Ethiopia. Our analysis is based on an integrated understanding of supply chain performance both from producer and from consumer perspectives. We outline as main drivers for quality upgrading: (a) factors that influence producers’ willingness to invest toward intensification by smallholder dairy farmers and cooperatives and (b) factors that induce consumer’s willingness to pay for healthy and nutritious dairy products delivered at specific retail outlets. Since there are large gaps between upstream producers incentives and downstream consumers motives, possibilities for dairy quality upgrading remain fairly limited. Given this market structure, decisive policy support is required for better tailoring producer’s investments with consumer preferences.  相似文献

The increasing participation of the CMEA countries of Eastern Europe in the international division of labor extends beyond simple trade relations to include a complex web of production arrangements, including tripartite industrial cooperation. The East is now treating its economic relations with the South in less ideological and political terms, and therefore has engaged in more pragmatic and profitable ventures. Socialist state enterprises have become more integrated into the world market as buyers, sellers and producers, and as such have begun to display characteristics that resemble those of Western firms.  相似文献

Arguments for and against monopoly and competition in the provision of telecommunication services are considered from the perspective of a dominant telecommunications operator in a small European country, Sweden. The importance of provision of public services is stressed as well as the need for efficient international standardization. Finally, it is argued that there is a parallel between the position of dominant telecommunication operators in small and medium-sized countries and the INTELSAT system.  相似文献
