社会主义和谐社会的经济制度基础研究是一门着眼于改革开放以来经济领域中思想解放的宏观历史进程,以深入研究经济变革中的一般经济制度、经济体制、基本经济制度以及经济发展观为理论重点,以彰显社会主义和谐社会的经济制度创新优势和实现人的全面而自由发展为实践目标的学问。     

范围经济与商业企业地理集群

商业企业地理集群已成为21世纪中国市场经济发展的新景观。基于博弈论构建了线性空间中寡头垄断市场结构下商业企业的区位选择模型,探究了商业企业空间集聚的经济机理。证明了在消费者具有多样化偏好的环境下,经营差异化产品商业企业的市场需求相互依赖,这导致了企业区位选择过程中的范围经济性。商业企业地理集群是具有完美预期的商业企业对消费者购物行为反应的均衡结果。还发现在均衡中商品的价格随着市场群落中产品差异性的扩大而增加。区位选择的模型不仅揭示了商业企业地理集群的经济机理,还可以解释涉及市场群落的许多现象。     

论民法中诉讼时效制度适用范围

在日常生活中,任何人都无法离开法律而生活,因为法律是与生活息息相关的。正如西方法律谚语所说:立法者不是创设法律,而是发现法律。生活离不开法律,法律来自于生活。生活里人们无时不刻地在为自己和他人创设权利与设置义务,从而生成各种民事法律关系。但是,权利与义务不会无休无止地存在,当一方信守承诺积极履行自己的义务时,另一方亦不能\"躺在权利的床上酣眠\"。不论是权利还是义务,都会有消亡的时刻,即一个时间限制,法律中叫做时效。为此,对中国公民哪些权利会受到时效的限制及该受多长时间的限制进行了论述。     

Jointness in production and farmers' willingness to supply non-marketed ecosystem services

This paper highlights how farmers' willingness to supply non-marketed ecosystem services (ES) is influenced by whether or not the non-marketed ES are produced jointly with agricultural products. When marketed products and non-marketed ES share some production inputs the production relationships between the two may be complementary, competitive or substitutive. Using a cost minimization framework, it is shown how complementary relationships lead to costless voluntary provision of non-marketed ES (typically the case for ES that are supportive of provisioning ES for marketed farm products). It is also shown how competitive production relationships lead to provision of non-marketed ES at lower cost than when non-marketed ES are direct substitutes for farm products or are produced outside of agriculture. The paper closes by showing how the minimum willingness to accept (WTA) payment for ES that are complementary/competitive is less than or equal to the minimum WTA for the same ES produced in substitute or independent production relationships.     

我国寿险公司范围经济效应的实证研究

我国自1996年实施产寿分业经营以来,人身保险业务快速增长,寿险公司数量急剧增加,寿险公司业务中新型寿险的比重不断上升,呈现出"一险独大"的市场状况。运用超越对数成本函数,对国内29家具有代表性的寿险公司2005-2010年期间的范围经济状况进行检验的结果显示:不同规模和背景的寿险公司的范围经济系数均比较明显,但是很多寿险公司所表现出来的范围经济性具有"欺骗性"。因此,寿险业务结构调整缺乏内部的市场激励,需要强有力的外部力量推动。     

Regulation and taxation: A complementarity

I show how quantity regulation can lower elasticities and thereby increase optimal tax rates. Such regulation imposes regulatory incentives for particular choice quantities. Their strength varies between zero (laissez faire) and infinite (command economy). In the latter case, regulation effectively eliminates any intensive behavioral responses to taxes; a previously distortionary tax becomes a lump sum. For intermediate regulation (where some deviation is feasible), intensive behavioral responses are still weaker than under zero regulation, and so quantity regulation reduces elasticities, thereby facilitating subsequent taxation. I apply this mechanism to labor supply and present correlational evidence for this complementarity: hours worked in high-regulation countries are compressed, and these countries tax labor at higher rates.

Career plateauing reactions: the moderating role of job scope,role ambiguity and participation among Canadian managers

The purpose of this study is to investigate the moderating effect and the interactive effect of job scope, role ambiguity and participation in decision-making on relationships between career plateauing and outcomes. A cross-sectional survey of 3,065 Canadian managers shows that these job characteristics can contribute to limiting the negative consequences associated with career plateauing. Moreover, in accordance with the theory of work–situation fit, some double moderating effects are found. The attitudes and behaviours of plateaued managers are significantly more positive when their job is richer and offers an opportunity to participate in decision-making. However, contrary to evidence in the literature, results show that reactions to career plateauing are more positive for managers who perceive that their job is richer and their role more ambiguous. Implications and directions for future research are discussed.
