Corporate governance theory suggests that companies with dispersed and indirect ownership suffer from agency costs. A worst case is where several political authorities jointly own a company, which allows managers to operate with inferior efficiency. In political economy, the manager is not the major agency problem. Elected politicians may impair efficiency to improve their re‐election prospects. Since politicians have less influence in jointly owned firms, such companies are expected to perform better than those owned by a single public authority. Consistent with corporate governance – but not political economy – the empirical analysis suggests that dispersed municipal ownership impairs cost efficiency. In the Norwegian case of municipal refuse collection presented here, costs of dispersed ownership often outstrip gains from economies of scale. Use of jointly owned companies is not necessarily a proper response to efficiency problems inherent a fragmented local government structure.  相似文献

The DNA commission of the International Society of Forensic Genetics (ISFG) was convened at the 21st congress of the International Society for Forensic Genetics held between 13 and 17 September in the Azores, Portugal. The purpose of the group was to agree on guidelines to encourage best practice that can be universally applied to assist with mixture interpretation. In addition the commission was tasked to provide guidance on low copy number (LCN) reporting. Our discussions have highlighted a significant need for continuing education and research into this area. We have attempted to present a consensus from experts but to be practical we do not claim to have conveyed a clear vision in every respect in this difficult subject. For this reason, we propose to allow a period of time for feedback and reflection by the scientific community. Then the DNA commission will meet again to consider further recommendations.  相似文献

Conclusion In 1984, after years of study and thorough debate, a bipartisan majority of the Congress enacted perhaps the most far-reaching reform of the federal criminal justice system in the history of the United States. The Sentencing Reform Act and the federal sentencing guidelines are now beginning to produce data indicating that the objectives of avoiding unwarranted disparity and invidious discrimination are being achieved.After an uncertain beginning, the guidelines are gaining acceptance by courts and criminal justice practitioners. As one appellate court observed in admonishing lower courts that the guidelines must be respected:We have embarked on a new course. Only time will tell whether the use of the guidelines will result in an improvement over the old system. But unless we follow the spirit and written directions of the guidelines, we will never know if they have been given a fair test. They at least deserve that.Indeed, the bold new approach to sentencing that is being followed today in federal courthouses throughout the United States deserves an opportunity to succeed, given its many beneficial features and the lofty goals toward which the reforms are directed. While ample work remains for the United States Sentencing Commission to monitor and improve the guidelines, indications at this still early date are that the experiment is succeeding.An earlier version of this paper was presented at the fifth conference of the Society for the Reform of Criminal Law, Parliament House, Edinburgh, Scotland, August 5–9, 1990. The views expressed herein are those of the authors and do not necessarily represent the official position of the United States Sentencing Commission.B.A., Davidson College 1964; J.D., University of South Carolina School of Law 1967.B.A., Ohio State University 1974; M.S., Arizona State University 1980; M.A., University of California, Santa Barbara, 1983.B.S., Clemson University 1971; M.S., Clemson University 1975; J.D., University of South Carolina School of Law 1978.  相似文献

New York State experimented with replacing their litigation-oriented system for achieving toxic dump site cleanup with one promising to lower transaction costs through alternative dispute resolution. Our analysis of outcomes is informed by three generations of implementation work focusing on (1) the motivations and incentives shaping individual behavior, (2) the larger organizational and political factors associated with variation across cases, and (3) the generic properties of policy implements. This mosaic approach to explanation produces, we believe, a more lifelike picture of use to policy makers for understanding the dynamic and interrelated nature of their choices.  相似文献

The EPA implements its policy of exhaust emission control by setting standards specified in terms of grams of pollutants per mile traveled. As a result, the tax must first restrain the vehicle miles traveled (VMT) if it is to have an impact on emission at all. EPA's choice of miles traveled as the medium through which its policy of pollution control must run is unfortunate, because travel is an activity that people resist giving up. This is reflected in a low long-run price elasticity of travel demand. Consequently, it takes substantial increases in the gasoline tax to make an impact on long-run travel demand. Simulation results show that under an alternative policy option, where EPA's standards are specified in terms of grams of pollutant per gallon of fuel burned, the same long-run reduction in exhaust emissions achievable today can be achieved (at an even higher level of confidence) with less than one-tenth of the increase in gasoline price required under the existing policy regime.  相似文献

  East Asia, including Northeast Asia and Southeast Asia, has developed tightly-linked production/distribution networks through globalizing corporate activities. The vertical chain of production in East Asia has been even more sophisticated than economic integration in East Europe or Latin America. However, the political environment of East Asia for trade and investment has been far from borderless. The integration effort at the policy level has been very much limited so far, due to the historical background as well as geopolitics surrounding East Asia. The Asian currency/financial crisis provided these countries a historical turning point. After the burst of the crisis, East Asians realized that they have to take care of themselves in their difficulties, not depending on outside forces. A natural choice for them was to step into the realm of regionalism. In 1998, Japan and Korea officially announced that they would discard the long-lasting GATT/WTO-only approach and adapt the multi-layered approach, including both regionalism and multilateralism. The ultimate goal of regionalism would be a region-wide integration including ASEAN+3. As a steppingstone, Japan signed the Japan-Singapore Economic Partnership Agreement (JSEPA) in January 2002. In a parallel move, the ASEAN and China Leaders announced in November 2001 the establishment of an ASEAN-China Free Trade Area (ACFTA) within 10 years. This article will follow up the most recent advancement of regional institutional building in East Asia with the emphasis on peculiar characteristics of economic integration in the region and discuss its implications for Asia-Europe relations. This paper is heavily drawn from Kimura (2002, 2003).  相似文献

Newspaper juries     
This article reports on a field experiment on the effect of media information on people’s attitudes towards the justice system. For the duration of a year a Dutch local newspaper took small groups of readers, called ‘newspaper jurors’, to court sessions of criminal cases and subsequently reported on their experiences and perceptions. Using a quasi-experimental design, we examined whether an attitude change in the general reader population of this particular local newspaper occurred as a result of the jury’s newspaper reports. Findings show that, after the treatment interval of 1 year, no attitude change in the general reader population could be identified that was absent in the control group.  相似文献
