This paper demonstrates howadditional rents are generated in a fisherycharacterized by intraseasonal variation infish characteristics, including size,condition, and composition. Based on anexpanded conceptual model of the optimalharvest rule, fish characteristics affect preand post harvest production yields and outputprices. A dynamic empirical model, which uses asystem of quality characteristics and anhedonic equation, illustrates the complexrelationships and management choices associatedwith internalizing seafood qualitycharacteristics in a hake fishery. The modelretains the regulated open access managementsystem, but controls intertemporal andintersectoral quotas, production portfolios,and total allowable catch. Results demonstratethat including revenue-side effects frominternalizing fish quality can generatesignificantly greater rents and reduce therelative benefits of increased productionyields. If excluded, bioeconomic models canunderestimate the level of regulatory rentdissipation and overemphasize managementobjectives such as full utilization, whichcould misdirect processing decisions and resultin a suboptimal resource management plan.Implications for data collection,multidisciplinary analysis, and improvements inmarine resource management are discussed. 相似文献

The effect of management commitment to service quality on employees’ affective and performance outcomes 总被引:1,自引:0,他引:1

A service recovery performance model is proposed and tested with data from frontline bank employees in Turkey. The model is
derived from Bagozzi's (1992) reformulation of attitude theory. The empirical results suggest that top management commitment
to service quality, as manifested by frontline employees' appraisal of training, empowerment, and rewards, has a significant
effect on their perceptions of service recovery performance. The influence of management commitment to service quality on
service recovery performance is mediated by frontline employees' affective commitment to their organization and job satisfaction.
Implications of the results and further research avenues are discussed.

2001年世界经济陷入了30年来最严重的衰退。这次衰退是继多年经济繁荣后的“硬着陆”,衰退导致世界经济增长曲线呈现“U”字型。从全球主要经济机构的预测结果看,2002年世界经济前景依然黯淡。世界经济的复苏,取决于美国经济的复苏,而美国经济复苏主要依靠扩张性政策的拉动,是政策导向型的复苏。面对严峻的外部经济环境,2002年中国经济要实现7%以上的增长,在立足于内需的同时,应对对外经济政策做适当的调整。 相似文献
