On large games with bounded essential coalition sizes

We consider games in characteristic function form where the worth of a group of players depends on the numbers of players of each of a finite number of types in the group. The games have bounded essential coalition sizes: all gains to cooperation can be achieved by coalitions bounded in absolute size (although larger coalitions are permitted they cannot realize larger per-capita gains). We show that the utility function of the corresponding "limit" market, introduced in Wooders (1988, 1994a) , is piecewise linear. The piecewise linearity is used to show that for almost all limiting ratios of percentages of player-types, as the games increase in size (numbers of players), asymptotically the games have cores containing only one payoff, and this payoff is symmetric (treats players of the same type identically). We use this result to show that for almost all limiting ratios of percentages of player-types, Shapley values of sequences of growing games converge to the unique limiting payoff.

社会资本与就业行为的实证研究

通过社会资本对就业行为作用和影响的实证研究可得出以下结论：不同的社会资本拥有量对就业资源的获取与利用不同；就业行为受社会资本与人力资本双重作用；社会资本在就业中对性别作用存在差异；就业行为中两个“关系强度”的效用不同。     

试论浙江现代商贸流通强省

改革开放以来,浙江作为市场大省,专业批发市场曾经并将继续在浙江经济体制改革、民间人才培养、民有资本聚集、个私经济发展等方面发挥极其巨大的作用。在当前新的国际、国内经济形势下,有必要针对存在的问题,引导专业市场进行整合、转型与提升,使之与现代商贸流通的业态、方式和组织相对接,努力把浙江由“市场大省”提升为“现代商贸流通强省”。     

Statistical manipulability of social choice functions

We consider the proportion of profiles at which an anonymous neutral social choice function cannot be manipulated to any coalition's advantage. We fix the number of alternatives and consider the limit as the number of individuals goes to infinity, and assume that the limit of the fraction of all profiles in the domain is 1. We show that there is a continuous function on “profile vectors’ which gives the maximum probability of strategy-proofness, and that this is strictly between 0 and 1 for three alternatives. We also analyze a number of common social choice functions along these lines.

Long Window Tests of China＇s Stock Market Efficiency in Different Sectors around the Disclosure of Annual Report

10 stock sectors are selected in Shanghai and Shenzhen stock market＇s as samples. By event study, the change of stock＇s cumulative abnormal return rate around the data of annual report disclosure was analyzed among the year 2004-2008. The market reaction pattern of such kind of news was summarized in order to test the efficiency of China＇s stock market and its trend before and after the comprehensive completion of the Share-trading Reform and the imple- mentation of new Accounting Standards. The conclusion is that Chinese stock markets response more accurately to ROE and EPS; its efficiency continued to decline in 2005 and 2006, but there was a gradual increase in 2007 and in 2008; and in general the capital market do not reach the semi-strong efficiency, but the machinery industry and biopharmaceutical industry have done.     

Linking material and energy flow analyses and social theory

The paper explores the potential of Habermas' theory of communicative action to alter the social reflexivity of material and energy flow analysis. With his social macro theory Habermas has provided an alternative, critical justification for social theory that can be distinguished from economic libertarianism and from political liberalism. Implicitly, most flow approaches draw from these theoretical traditions rather than from discourse theory. There are several types of material and energy flow analyses. While these concepts basically share a system theoretical view, they lack a specific interdisciplinary perspective that ties the fundamental insight of flows to disciplinary scientific development. Instead of simply expanding micro-models to the social macro-dimension social theory suggests infusing the very notion of flows to the progress of disciplines. With regard to the functional integration of society, material and energy flow analyses can rely on the paradigm of ecological economics and at the same time progress the debate between strong and weak sustainability within the paradigm. However, placing economics at the centre of their functional analyses may still ignore the broader social integration of society, depending on their pre-analytic outline of research and the methods used.

Analysis on Variety Structure of High-quality Wheat in Henan Province

The essential parts of Henan wheat economy are production, processing and international trade of high-quality wheat. The initial aspect that affects high-quality wheat development is variety structure. This paper analyzes high-quality wheat＇s quality structure, variety structure, contribution of them to total yield, and anticipation on wheat production and development of wheat economy in Henan. In conclusion, the result indicates that the high-quality wheat production is on the rise, which presents ＂s＂ shape by means of area. Although the overall tendency of high-quality wheat breeding is diversity-oriented, two or three varieties are in a commanding position, especially the ＂Zheng Mai＂ series get outstanding contribution during the ＂10^th Five-year Plan＂.
