This article first describes the new literature in environmental economics on the so‐called “double‐dividend” and then explores its implications for a broad range of economic issues. This literature reveals that in a second‐best, general‐equilibrium setting, environmental measures raise costs and prices and thereby reduce the real wage. This rise in the cost of living reduces slightly the quantity of labor supplied in an already highly distorted labor market, giving rise to losses in social welfare that can be large relative to the basic gains from a cleaner environment. These losses can be offset to some extent by using revenues (if any) from the environmental programs to reduce existing taxes on labor. This same line of analysis applies to many programs and institutions in the economy that raise the cost of living: tariffs and quotas on imports, agricultural price‐support programs, monopoly pricing, programs of occupational licensure that limit entry, and many others. Thus, traditional, partial‐equilibrium benefit‐cost analysis appears, in many instances, to have unwittingly omitted from the calculations a potentially quite significant class of social costs. © 2000 by the Association for Public Policy and Management. 相似文献

Color determination of soil evidence is often done by visual comparison to soil color charts. A handheld spectrophotometer was tested with representative materials for its suitability for forensic soil characterization. Instrumental colorimetry provides accurate colorimetry with ~10-fold better precision than a soil color chart. The minimum sample size for accurate color determination was between 0.02 and 0.04 mg of fine soil for the specific instrument tested. Reporting colors in the L*a*b* space permits quantification of ΔE00, a measure of perceptible color difference, could enable objective quantification of small color differences and thresholds for forensic soil comparisons. A ΔE00 greater than ~ 3.5 to 6 likely indicates disparate soil sources in a forensic comparison, in the absence of confounding factors like sample alteration. Despite the superior precision of instrumental colorimetry, this approach is inappropriate for samples which are mottled at an inseparable scale, attached to a substrate, or too small for instrumental measurement. 相似文献

This article shows how wildlife and marine conservation in Tanzania lead to forms of ‘green’ or ‘blue grabbing’. Dispossession of local people's land and resources has been gradual and piecemeal in some cases, while it involved violence in other cases. It does not primarily take the usual form of privatization of land. The spaces involved are still formally state or village land. It is rather the benefits from the land and natural resources that contribute to capital accumulation by more powerful actors (rent-seeking state officials, transnational conservation organizations, tourism companies, and the State Treasury). In both cases, restrictions on local resource use are justified by degradation narratives, while financial benefits from tourism are drained from local communities within a system lacking in transparent information sharing. Contrary to other forms of primitive accumulation, this dispossession is not primarily for wage labour or linked to creation of a labour reserve. It is the wide-open spaces without its users that are valued by conservation organizations and the tourism industry. The introduction of ‘community-based conservation’ worked as a key mechanism for accumulation by dispossession allowing conservation a foothold in village lands. This foothold produced the conditions under which subsequent dispossessions could take place. 相似文献

The IAASTD – the International Assessment of Agricultural Knowledge, Science and Technology for Development – which ran between 2003 and 2008, involving over 400 scientists worldwide, was an ambitious attempt to encourage local and global debate on the future of agricultural science and technology. Responding to critiques of top-down, northern-dominated expert assessments of the past, the IAASTD aimed to be more inclusive and participatory in both design and process. But to what extent did it meet these objectives? Did it genuinely allow alternative voices to be heard? Did it create a new mode of engagement in global arenas? And what were the power relations involved, creating what processes of inclusion and exclusion? These questions are probed in an examination of the IAASTD process over five years, involving a combination of interviews with key participants and review of available documents. The paper focuses in particular on two areas of controversy – the use of quantitative scenario modelling and the role of genetically-modified crops in developing country agriculture. These highlight some of the knowledge contests involved in the assessment and, in turn, illuminate four questions at the heart of contemporary democratic theory and practice: how do processes of knowledge framing occur; how do different practices and methodologies get deployed in cross-cultural, global processes; how is ‘representation’ constructed and legitimised; and how, as a result, do collective understandings of global issues emerge? The paper concludes that, in assessments of this sort, the politics of knowledge needs to be made more explicit, and negotiations around politics and values, framings and perspectives, need to be put centre-stage in assessment design. 相似文献

Policy innovation is a significant challenge for the public sector. This article illustrates its magnitude through a case study of the National Innovation Summit. The article concludes that the Summit represented an elaborate process of search and engagement that sanctioned an outcome that was, in most respects, largely pre‐determined. Its outreach and deliberations served the political purpose of mobilising industry and media attention and communicating the government's commitment. But there is no evidence that it exercised any substantive influence on policy development. The obstacles confounding any other outcome are considerable. Strategic thinking is inhibited by various organisational factors including lock‐in to a present successful strategy, the constraints on policy choices associated with multiple veto points and the need to maintain medium term fiscal and policy discipline across a wide range of agencies and claimants. The article explores ways these inhibitions might be overcome. 相似文献

Little is known about the social networks of homeless youth in emerging adulthood despite the importance of this information
for interventions to reduce health risks. This study examined the composition of social networks, and the risks and supports
present within them, in a random sample of 349 homeless youth (33.4% female, 23.9% African American, 17.7% Hispanic) between
the ages of 18 and 24. Social network members who were met on the street were among the most likely to be perceived as engaging
in risky sex, as well as to engage in substance use with the youth. Youth were more likely to count on relatives and sex partners
for support compared to other network members, but they also were more likely to use substances with sex partners and perceived
them as engaging in risky sex. Interventions may need to recognize the importance of intimate relationships during the developmental
stage of emerging adulthood by enhancing supportive bonds and reducing substance use and risky sex in these relationships. 相似文献

Although public management reforms around the world have given business experts an enhanced role in the governance of public sector organizations, the impact of this change is poorly understood. Drawing from the literature on board human capital as a theoretical framework and focusing on the case of hospital boards in the English National Health Service, this concern is addressed by investigating whether increasing the presence of individuals with business expertise has any significant relationship with organizational performance. The findings show that while business expertise appears to have no influence on service quality, it does have a positive effect on financial performance. However, this only applies to governing boards that are less experienced in terms of their collective tenure. The findings lend partial support to board capital theory but also show that in certain conditions generic business expertise can be a valuable asset for public sector organizations. 相似文献
