Many tout the benefits of collaborative environmental management as an alternative to centralized planning and command and control regulation, but the excitement over collaborative processes has not been matched by evidence that these processes actually improve the environment. The most crucial question in collaborative environmental management remains unanswered and often unasked: To what extent does collaboration lead to improved environmental outcomes? We know much about why collaboration is occurring and how collaborative processes and outputs vary. The primary goal of future research on collaborative environmental management should be to demonstrate whether collaboration improves environmental conditions more than traditional processes and newer market-based processes. Collaboration is not a panacea; it is a choice that policy makers and public managers should make based on evidence about expected outcomes.  相似文献

In 2006, the Public Choice Society chose a new president using approval voting. There were five candidates, and the election was extremely close. We indicate the sources of support of the different candidates, based in part on spectral analysis, by voters who cast between one and five votes. Using preference information that was also gathered, we show that two candidates different from the approval voting winner, including the apparent Condorcet winner, might have won under different voting systems. Because most voters did not indicate their complete preference rankings, however, these differences are hardly robust, especially since the outcome was essentially a dead heat.  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

The article analyses the policy termination literature that originated during the 1970s in the USA. It discusses the value of the traditional termination concept and the (meagre) empirical results of now three decades of its application. The article argues that policy termination may still be a promising policy analytical tool ’ if appropriately revised and refocused. The final part of the article suggests possible ways of reviving the policy termination concept by concentrating seriously on policy content, ideology and the cohesion of potential losers of termination decisions.  相似文献
