Corruption perceptions vs. corruption reality 总被引:2,自引:0,他引:2
This paper examines the accuracy of corruption perceptions by comparing Indonesian villagers' reported perceptions about corruption in a road-building project in their village with a more objective measure of ‘missing expenditures’ in the project. I find that villagers' reported perceptions do contain real information, and that villagers are sophisticated enough to distinguish between corruption in a particular road project and general corruption in the village. The magnitude of the reported information, however, is small, in part because officials hide corruption where it is hardest for villagers to detect. I also find that there are biases in reported perceptions. The findings illustrate the limitations of relying solely on corruption perceptions, whether in designing anti-corruption policies or in conducting empirical research on corruption. 相似文献

Intervention analysis is proposed as a method for estimating the effects of anti-dumping actions in the presence of a domestic cartel. Data requirements and modelling effort compare favourably with traditional structural model approaches. The method is applied to an anti-dumping action brought to the European Commission and in which the European producers of the product were fined after an anti-cartel action by the Commission covering an overlapping period. Interven tion analysis is applied to distinguish the effects of the anti-dumping action from those of changes in cartel behaviour 相似文献

Die Wettbewerbssituation auf dem deutschen Bahnmarkt ist vielschichtig: Sowohl die verschiedenen Teilsegmente des Bahnmarktes
als auch der intermodale Wettbewerb müssen berücksichtigt werden. Dabei besteht die Gefahr, die Wettbewerbsposition des gesamten
Eisenbahnverkehrs gegenüber anderen Verkehrstr?gern aus den Augen zu verlieren. 相似文献

Hydropower can provide inexpensive, flexible fill-in power to compensate for intermittent renewable generation. Policies for
hydropower dams maintain multiple services beyond electric generation, including environmental protection, flood control and
recreation. We model the decision of a hydroelectric generator to shift some of its power production capacity away from the
day-ahead energy market into a “wind-following” service to smooth the intermittent production of wind turbines. Offering such
a service imposes both private and social opportunity costs. Since fluctuations in wind energy output are not perfectly correlated
with day-ahead energy prices, a wind-following service will necessarily affect generator revenues. Seasonal wind patterns
produce conflicts with the goal of managing rivers for “ecosystem services”—the maintenance or enhancement of downstream ecosystems.
We illustrate our decision model using the Kerr Dam in PJM’s territory in North Carolina. We simulate the operation of Kerr
Dam over a three-year period that features hydrologic variability from normal water years to extreme drought conditions. We
use an optimization framework to estimate reservation prices for Kerr Dam offering wind-following services in the PJM market.
Wind-following may be profitable for Kerr Dam at low capacity levels during some time periods if ecosystems services are neglected
and if side payments, or reserves-type payments, are provided. Wind-following with ecosystem services yields revenue losses
that typically cannot be recovered with reserves market payments. Water release patterns are inconsistent with ecosystem-services
goals when Kerr Dam dedicates significant capacity to wind-following, particularly in drought years. 相似文献

We examine the relationship between housing equity and wage earnings using nine waves of the national American Housing Survey from 1985 to 2003. Employing a rich set of time and place controls, a synthetic mortgage instrumental variable strategy, and a first difference estimator we find that people underwater on their mortgage command a significantly lower wage than other homeowners. The finding survives a number of robustness checks for reverse causality and unobserved heterogeneity. We also explore other determinants of “house lock” including loss aversion, a low existing mortgage interest rate and property tax assessment caps, but do not find these factors mitigate the effect of negative equity on wages. 相似文献
