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

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 article contributes to the development of theories on European integration by testing and exploring statistical models on the long-term development of legislative activity of the European Commission. Drawing on legal information gained from the European Union’s PreLex database and analyzing it with the help of statistical analyses, we map out growth patterns of EU law between 1976 and 2003. We construct time-series models and models based on non-linear regression. While the performance of models based on the traditional theoretical approaches, intergovernmentalism and neo-functionalism, is rather poor, the analysis suggests that nonlinear dynamic models might be an interesting avenue for future conceptualizations of the EU integration process. This article is based on a paper presented at the ECPR Standing Group on the European Union Second Pan-European Conference on EU Politics, “Implications of a Wider Europe: Politics, Institutions and Diversity”, 24–26 June 2004, Bologna, Italy. We would like to thank the seminar participants for useful comments.  相似文献

COMPSTAT, the latest innovation in American policing, has been widely heralded as a management and technological system whose elements work together to transform police organizations radically. Skeptical observers suggest that COMPSTAT merely reinforces existing structures and practices. However, in trying to assess how much COMPSTAT has altered police organizations, research has failed to provide a broader theoretical basis for explaining how COMPSTAT operates and for understanding the implications of this reform. This article compares two different perspectives on organizations—technical/rational and institutional—to COMPSTAT's adoption and operation in three municipal police departments. Based on fieldwork, our analysis suggests that relative to technical considerations for changing each organization to improve its effectiveness, all three sites adopted COMPSTAT in response to strong institutional pressures to appear progressive and successful. Furthermore, institutional theory better explained the nature of the changes we observed under COMPSTAT than the technical/rational model. The greatest collective emphasis was on those COMPSTAT elements that were most likely to confer legitimacy, and on implementing them in ways that would minimize disruption to existing organizational routines. COMPSTAT was less successful when trying to provide a basis for rigorously assessing organizational performance, and when trying to change those structures and routines widely accepted as being "appropriate." We posit that it will take profound changes in the technical and institutional environments of American police agencies for police departments to restructure in the ways anticipated by a technically efficient COMPSTAT.  相似文献

What is required for sustaining an alliance between union and environmental activists? Applying grounded theory to a case study in the Costa Rican banana sector, this article reveals five historical phases. First, unions and environmentalists identify common opportunity structures for joint action. Second, a preexisting network becomes a resource for mobilization. Third, the new coalition engages in communicative action that leads to shared identity and cultural framing and a foundation for handling exogenous global forces. Market policy changes in the fourth phase stimulate a transnational activist network and framing linkages. Dramatic supply disruptions in the fifth precipitate autonomous organizational approaches that require reframing, identity extension, and flexibility. This study argues that the Costa Rican case can be generalized to other labor‐environmental coalitions if such alliances create simple, open structures that agilely adapt to external opportunity structures and expand frames that encourage collaborative autonomy and dualistic collective definitions.  相似文献
