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 process is not the problem, the problem is the problem. Rudolph Penner (1984). …We argue the superiority of the outcome from the process, not of the process from the outcome. The constancy of the economist's objection to this conclusion when applied to governmental rather than market decisions simply often reflects the fact that, while some economists are not disturbed that consumer preferences lead to allocation policies other than best respond to their own tastes, when political preferences lead to governmental policies not consistent with his informed and considered preferences, they are tempted to attribute irrationality to government.  相似文献

The rare event of a corpse immersed in glacier ice becoming exposed on a glacier surface is closely connected with the glaciological conditions at the scene and the site of the accident. Provided that the time since death is known, certain questions relative to the circumstances of a mountain accident can only be answered by considering glaciological aspects. How the scene of an accident can be reconstructed by inference from the site of discovery is discussed by means of three exemplary cases that occurred on Tyrolean glaciers (Austria) during the past 40 years: (1) Two corpses were discovered close above the equilibrium line in the accumulation area after 25 years. The two victims had fallen down a rock face after the breaking off of a cornice and had come to rest in the uppermost part of the accumulation area. (2) A victim was discovered in the lower ablation area 8 years after falling down a crevasse in the middle part of the ablation area. (3) A female alpinist was discovered at the very end of the glacier after 29 years; it was concluded that the accident must have happened in the accumulation area.  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.

Banks are “special” financial institutions generating distinct corporate governance challenges. The present paper examines the relationship between two of the most pertinent corporate governance factors—that is, the size of the Board of Directors and the proportion of non-executive directors—and firm performance on a sample of 58 large European banks over the period 2002–2004. The empirical analysis embraces a number of bank-specific variables. Our results reveal that bank profitability is negatively related to the size of the Board of Directors, while the impact of Board composition, although positive in all models, is, in most cases, insignificant. The results are robust after controlling for firm-specific variables.   相似文献
