The conventional wisdom suggests that a stricter enforcement policy can reduce pollution emissions. Nevertheless, this present paper argues that this assertion does not necessarily hold if the stringency of environmental regulation is subject to the influence of lobbying. A stricter enforcement policy increases the polluters’ expected financial burden, and induces them to exert greater political pressure on reducing the stringency of environmental regulation, thereby resulting in a larger amount of pollution emissions. We also show that tightening the enforcement policy can reduce efficiency. We highlight the possibility of policymaking being misguided due to overlooking the political effect of enforcement policy. 相似文献

A Generic Framework for Automated Multi-attribute Negotiation 总被引:1,自引:0,他引:1
Agents in a negotiation may have to negotiate multiple issues simultaneously. Automated multi-attribute negotiation provides
an important mechanism for distributed decision makers to reach agreements on multiple issues. Moreover, it also furnishes
the opportunity to reach “win–win” solutions. In this paper, we first provide a survey that synthesizes the research on multi-attribute
negotiation. We discuss the limitations of the existing research and conclude that three key issues need further study: incomplete
information, Pareto optimality, and tractability. We then present a generic framework for automated multi-attribute negotiation
with two new mechanisms that address the above issues. Finally, we discuss the challenges and directions for future work. 相似文献

This paper extends the gaps model of [Zeithaml, V.A., Parasuraman, A., Berry, L. 1990. Delivering Quality Service: Balancing Customer Perceptions and Expectation. The Free Press, New York] from the service provider to the business customer side by examining two service quality (SQ) gaps. One is the SQ gap between types of business customers and the other is the SQ gap among employee statuses of business customers. Besides that, the five-factor SERVQUAL measure as the initial hypothesized model is also tested. The applicability of SERVQUAL to measuring the perceived SQ of customers in the shipping industry of Taiwan is rejected empirically. The existence of the two hypothesized gaps is verified by the method of MANOVA. 相似文献

A number of prior studies have developed a variety of multivariate volatility models to describe the joint distribution of spot and futures, and have applied the results to form the optimal futures hedge. In this study, the authors propose a new class of multivariate volatility models encompassing realized volatility (RV) estimates to estimate the risk‐minimizing hedge ratio, and compare the hedging performance of the proposed models with those generated by return‐based models. In an out‐of‐sample context with a daily rebalancing approach, based on an extensive set of statistical and economic performance measures, the empirical results show that improvement can be substantial when switching from daily to intraday. This essentially comes from the advantage that the intraday‐based RV potentially can provide more accurate daily covariance matrix estimates than RV utilizing daily prices. Finally, this study also analyzes the effect of hedge horizon on hedge ratio and hedging effectiveness for both the in‐sample and the out‐of‐sample data. © 2009 Wiley Periodicals, Inc.

To specify the problem of unemployment in Russia, we estimate the natural rate of unemployment by consecutively estimating the optimal size of the labour force and the optimal employment. For estimation of the optimal values we used a modified Hodrick–Prescott filter technique. The results show that the natural rate of unemployment in Russia during 1994–97 was stable around 13–13.5% and decreased to 7.1% by mid-2004. Moreover, before 1998 the actual unemployment was significantly lower than the natural rate and today practically equals it. 相似文献

This study compared the perceptions of various important job applicant characteristics, job characteristics and job benefits between 107 corporate recruiters and 191 business undergraduates in Singapore. Results indicated significant incongruence between recruiter and student perceptions of a large number of job characteristics and benefits. However, perceptual differences were less extensive in the case of applicant attributes. The implications of these findings, and suggestions for greater perceptual congruence between recruiters and applicants, are discussed. 相似文献
