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

This paper links the policy context regarding S&T parks to the objectives and characteristics of the established parks and incubators in a relatively small, converging European country. S&T parks and incubators in Greece during the past decade and a half have gradually shifted in terms of ownership and management from university/research institute to the private sector and in terms of financing from public to private funds, also involving the provision of seed capital and access to venture capital. This gradual shift toward more private engagement has created a variety of models out of which, it is hoped, successful innovative companies will emerge in larger numbers than in the past.

Criminologists have long debated the issue of how to define crime, and hence, the scope of criminological inquiry. For years, some critical criminologists have argued for expanded definitions of crime that include harmful behaviors of the state that may not be officially defined as criminal. Other critical criminologists have argued that existing legal frameworks may be used to study varieties of state crime, and that defining the harmful actions of the state as criminal is important to help mobilize public support for their control. In this paper, we first trace the historical development of these two perspectives, and then offer a tentative solution to the seeming tension between these two perspectives.  相似文献
