摘要： "Whistle-blowing" is an increasingly common element of regulatory enforcement programs and one that is encouraged by recent legislation in the United States and elsewhere. We examine how responsive regulators should be to whistle-blower tip-offs and how severe should penalties be for wrongdoers detected in this way. Competing psychological theories as to what motivates employees to become whistle-blowers are operationalized as alternative behavioral heuristics. Optimal policy depends upon the motives attributed to whistle-blowers-025EFwhich of the theories you subscribe to-025EFbut is not in general characterized by maximal penalties nor routine pursuit of complaints, even when pursuit is costless.

摘要： In this Paper. entropy algorithm for controlling chaos. is applied to it Cournot duopoly with different constant marginal costs, its it discrete-time dynamical system which shows chaotic behavior. The ME control is implemented through delayed feedback. It is assumed that the equations of the dynamical system are not known. so the feedback gain cannot be obtained analytically front the system equations. In the ME method file feedback gain is obtained adaptively in such it way that the entropy of the system converges to zero, hence a fixed point of file system will be stabilized. Application of the proposed Method With different economic control strategies is numerically investigated. Simulation results show the effectiveness of the ME method for Controlling Chaos in economic systems with unknown equations. (C) 2007 Elsevier Ltd. All rights reserved.

摘要： 现有FDI区位问题的研究多强调各类传统区位因素的作用,却忽略了地理空间效应的影响。文章采用空间计量经济模型与普通计量经济模型对比分析的方法,对中国大陆省域FDI区域分布决定因素进行了研究。结果表明,中国FDI区域分布决定除受传统因素影响外,空间效应因素的作用也不可忽视,并对我国(尤其中西部地区)引进FDI具有重要政策启示。

摘要： 经济的发展和能源(包括煤炭)的利用有着密不可分的关系.运用国际上研究能源消费与经济增长之间关系的重要工具-协整分析、格兰杰因果关系检验对世界主要煤炭消费国家(中国、美国、印度、俄罗斯、日本和南非)1981-2005的煤炭消费与GDP之间因果关系及其内在规律进行了分析和研究.实证研究结果表明,这些国家能源消费结构、经济政策不同,煤炭消费同经济增长之间的因果关系也不完全一致,中国、日本和南非存在经济增长对煤炭消费的因果关系,俄罗斯存在煤炭消费对经济增长的因果关系,而印度煤炭消费和经济增长之间则不存在因果关系.据此各国根据自身能源国情及国际比较形势,制定科学的能源战略与政策.

摘要： This study explores the economic attractiveness of afforestation as a strategy for the joint production of fibre, carbon storage and biosolids (treated municipal sewage sludge) disposal for municipalities in Southern and Central Ontario, Canada. We use a spatial, stochastic model, the Canadian Forest Service Afforestation Feasibility Model (CFS-AFM), to simulate a range of spatial biosolids application scenarios in hybrid poplar afforestation projects. Results suggest that such joint afforestation strategies could be financially attractive. Significant cost savings can be expected through decreases in transportation distances and avoided waste disposal fees. Sensitivity analysis is used to examine the effects of variations in critical model parameters on net present values. Our findings indicate that waste disposal savings from application of biosolids on hybrid poplar plantations combined with incentives for landowners to sequester carbon can easily compete with agricultural land rental values in some regions of Ontario. Social acceptance of this kind of activity, however, may be an impediment to adoption. (C) 2008 Elsevier Ltd. All rights reserved.
