This paper examines a number of demographic aspects in congressional districts and states that played important roles in a series of Congressional votes on environmental issues in 2000. These characteristics include urbanization or population density, education, income, race, and employment. Our findings are mixed. While we find some evidence (at least in Senate votes) that population density is a positive predictor of “pro-environment” votes, we also find that things commensurate with the Environmental Kuznets Curve such as income, education, and lifestyle also play an important role in environmental voting.  相似文献

Networks of local government support organisations (LGSOs) are critical to successful intergovernmental relations and effective local governance in democratic societies. Bulgaria had no such network of municipal associations when it began the transition from communist rule in the early 1990s. Using US and other external technical assistance, Bulgaria over the next decade overcame the impediments to collective action and established what appears to be an effective and sustainable system to back up its cities and towns. Important factors in mobilising support included a long‐term focus on institutional development, non‐partisanship, flexibility in implementation and a pragmatic orientation that focused on learning by doing.

Public management scholars often claim that agency competition provides an effective institutional check on monopoly authority, and hence, leads to improvement of administrative performance in public sector agencies. This logic was central for creating the Congressional Budget Office (CBO) in 1975 to challenge the policy information provided by the Office of Management and Budget (OMB). We challenge this conventional wisdom by demonstrating that CBO has failed to enhance the quality of U.S. fiscal policy analysis on its own terms; nor has it spurred improvements in OMB's performance. Our empirical results indicate that the quality of OMB's fiscal projections has often deteriorated since the establishment of CBO as a rival bureau. We also show that both public and private information is being shared by these agencies to produce a similar caliber of task outputs. The broader implications of our study indicate that although politicians face incentives to employ agency competition in governmental settings, this type of bureaucratic strategy does not necessarily enhance the quality of administrative performance. © 2006 by the Association for Public Policy Analysis and Management  相似文献

This paper examines the relationship between job sprawl and the spatial mismatch between blacks and jobs. Using data from a variety of sources, including the 1990 and 2000 U.S. Census and U.S. Department of Commerce's ZIP Code Business Patterns, I control extensively for metropolitan area characteristics and other factors. In addition, I use metropolitan area physical geography characteristics as instruments for job sprawl to address the problem of simultaneity bias. I find a significant and positive effect of job sprawl on mismatch conditions faced by blacks that remains evident in the twostage least squares models but not in first difference change regressions. The crosssectional effect is particularly important in the Midwest and West, and in metropolitan areas where blacks' share of the population is large and where blacks' population growth rate is relatively low. Among others, the results also reveal that the measures of mismatch and job sprawl used in this analysis are highly correlated with blacks' employment outcomes in the expected direction. © 2006 by the Association for Public Policy Analysis and Management  相似文献

Youth crime is a serious social problem, as is the high proportion of young offenders in the juvenile justice system who have mental disorders. A recent policy innovation applies the theory of therapeutic jurisprudence and diverts youth with mental disorders to treatment in lieu of further court processing. The expansion of mental health diversion programs reflects an increasingly popular view that there is a causal relationship between youth mental disorders and crime. Policymakers who share this view place greater emphasis on rehabilitation and treatment as a way to reduce crime, rather than on stricter punishment. This paper considers the policy issues around youth mental health diversion programs. In addition, it evaluates the effect of a mental health diversion program for youth that was implemented in Texas. The paper finds that mental health diversion can be used effectively to delay or prevent youth recidivism.  相似文献

The widespread use over the past two decades of Michigan's PA 198 Industrial Tax Abatement program provides an opportunity to assess the inter‐urban equity impacts of this economic development tool. Not only has PA 198 been used relatively more often by suburban municipalities, local governments at the metropolitan periphery are more likely to use abatements to attract new plants and new jobs. The older central cities primarily use the program to retain existing jobs, albeit at high cost of lost tax revenues. On balance, it appears that PA 198 has done little to alter the location decisions of participating firms.  相似文献

The debate between proponents of metropolitan consolidation and polyarchic fragmentation poses many conflicting arguments, offers varied hypotheses, and reaches multiple conclusions about the effects of political structures and institutional arrangements on democratic governance. Despite varied and widespread attention to the topic, however, little resolution has been offered to appease either side. Additionally problematic is that implicit in both of these schools of research is the assumption that efficiency, whether achieved in fragmented or consolidated settings, is the prime preference of the citizenry. In this article, I specifically pursue the following research question: How do jurisdictional and metropolitan configurations influence the responsiveness of urban governments to public opinion? My findings illustrate that not only is considering the effect of metro place on city space a necessary and important pursuit, but a broader conceptualization of citizen preferences is of critical importance to scholars of urban politics, especially when assumptions about public opinion motivate choices about institutional sizes and structures.  相似文献

An important public policy question that remains unresolved iswhether devolution will enhance sensible policy making byexploiting informational asymmetries or, instead, trigger a``beggar thy neighbor'' response and stimulate free ridingamongst localities. We analyze this question within theframework of U.S. environmental policymaking by scrutinizing aunique panel data set on state-level endangered speciesexpenditure patterns. Our empirical estimates are consistentwith the notion that states free ride, which may lead to anexpenditure equilibrium that is not Pareto efficient.  相似文献

This study examines the role of car ownership in facilitating employment among recipients under the current welfare‐to‐work law. Because of a potential problem with simultaneity, the analysis uses predicted car ownership constructed from two instrumental variables, insurance premiums and population density for car ownership. The data come from a 1999–2000 survey of TANF recipients in the Los Angeles metropolitan area. The empirical results show a significant independent contribution of car ownership on employment. The presence of an predicted ownership is associated with a 9 percentage point increase in the odds of being employed. Moreover, the results indicate that lowering insurance premiums by $100 can increase the odds of employment by 4 percentage points. © 2002 by the Association for Public Policy Analysis and Management.  相似文献
