Group Selection and the Limits to Altruism

Several evolutionary mechanisms have been identified in the literature that would generate altruism in humans. The most powerful (except for kin selection) and most controversial is group selection, as recently analyzed by Sober & D.S. Wilson. I do not take a stand on the issue of the existence of group selection. Instead, I examine the level of human altruism that could exist if group selection were an engine of human evolution. For the Sober & Wilson mechanism to work, groups practicing altruism must grow faster than other groups. I call altruistic behavior that would lead to faster growth efficient altruism. This often consists of cooperation in a prisoner's dilemma. ltruistic acts such as helping a temporarily hungry or injured person would qualify as efficient altruism. Efficient altruism would also require monitoring recipients to avoid shirking. Utilitarianism would be an ethical system consistent with efficient altruism, but Marxism or the Rawlsian system would not. Discussions of efficient altruism also help understand intuitions about fairness. We perceive those behaviors as fair that are consistent with efficient altruism. It is important to understand that, even if humans are selected to be altruistic, the forms of altruism that might exist must be carefully considered and ircumscribed.     

非国有经济发展对中国经济增长质量影响机理研究——来自VEC模型的新证据

转轨以来,中国非国有经济的发展促进了经济增长的数量扩张.这是因为,经济非国有化改革作为一种制度创新,是一种增量式改革.这种改革使得体制内利益在未受影响的条件下,实现了帕雷托式的增长.然而,非国有经济的发展并没有带来中国经济增长质量的同比改善.这是因为,中国民营企业发展一般都过分强调以利润为中心,忽略环境成本,并且由于融资困难等因素导致了其技术创新能力的弱化;其次,中国引进的外资不仅在技术和管理创新的扩散效应上没能达到预期效果,而且日益增加的加工贸易通过转移定价方式使中国经济不能充分享有出口增长带来的利润贡献.

经济全球化进程中城市群发展的制度创新

从我国城市群目前的发展现状来看,影响城市群发展的主要因素是制度障碍:城市群跨界需求与行政区分割的障碍、缺乏城市群一体化发展的协调政策、没有形成有效的空间管理机制。因此,制度创新应是发展我国城市群的关键所在,重点是在法律制度、空间规划和管理制度等方面的创新。

中国产业结构变迁与经济增长的实证分析

本文对我国1978～2002年产业结构变化状况和产业结构变化趋势进行定量分析,考察产业结构变动引起各产业部门对经济增长的贡献和作用的相应变化.实证检验表明,这一时期我国产业结构变动基本符合工业化发展的演变规律,但从我国经济发展的要求看,产业结构转换仍滞后于总量增长的要求;进一步优化产业结构,需要着力解决"三农"问题、提升企业的国际竞争力、加快发展第三产业.     

中美公众对收入差距的反应差异探讨

中美的基尼系数如实地反映了两国的收入差距。中美两国民众对收入差距反应有差异的原因是因为两国的收入分配形状、社会保障水平、经济发展水平、非法收入的社会影响不同。由此可得出这样一个结论：要缩小我国收入差距，就必须在农村实行规模经济，完善社会保障，加大打击非法收入的力度。     

Régulation School and environment: Theoretical proposals and avenues of research

The article explores the relevance of a particular approach of the institutionalist movement, régulation theory, to deal with the relationship between the economy and the environment. Régulation theory, which appeared in France at the end of the 1970s, is mainly interested in macroeconomic issues. In contrast, until now it has tended to neglect environmental questions. By taking several key concepts of this theory (accumulation regime, mode of régulation, institutional forms), we have sought to assess its significance vis-à-vis the environmental field. More precisely, from the perspective of establishing an environmental regulationist theory, we propose considering the economic relation to the environment as the articulation of three forms: a transhistorical form, a general capitalist form and a specific capitalist form, the latter being variable in capitalist time and space. We give several illustrations of the variability of the relation to the environment, depending on the different accumulation regimes and the different modes of régulation. Two principal avenues of research are proposed: historical analyses for given economic areas, and comparative analyses relating in particular to different capitalist areas.     

中国期货市场的回顾与展望

中国期货市场产生于中国由计划经济向市场经济转轨的过程中，其形成与发达国家期货市场迥然不同。随着中国经济的逐步市场化，中国经济的逐渐国际化，政府扮演的角色的重要程度势必越来越小，期货市场在市场经济中将会充分发挥其功能，成为中国市场经济体系不可或缺的组成部分。     

地方官员与经济增长——来自中国省长、省委书记交流的证据

通常认为地方官员在我国经济发展中扮演着积极角色,近来国家也有意通过干部交流促进省区平衡发展,但国内还没有定量识别地方官员影响经济增长的文献。本文基于1978—2005年间省长(书记)交流样本构造了省长(书记)与省区相匹配的面板数据,系统地实证分析省长(书记)交流对流入省区经济增长的影响(即省长交流效应),结果发现,整体而言,省长交流能够使流入地的经济增长速度提高1个百分点左右;这种省长交流效应是通过在流入地采取大力发展二产、重视一产、忽视三产的产业发展取向实现的。本文的发现是稳健的,有助于增进对加强干部交流破解省区发展不平衡的理解。
