On the generic impossibility of truthful behavior: A simple approach

Summary We provide an elementary proof showing how in economies with an arbitrary number of agents an arbitrary number of public goods and utility functions quasi-linear in money, any efficient and individually rational mechanism is not strategy-proof for any economy satisfying a mild regularity requirement.The authors wish to thank William Thomson, Salvadpr Barberá, José Angel Silva and an anonymous referee for helpful comments. The remaining errors are our exclusive responsibility.

Cultural Inertia and Uniformity in Organizations

We analyze aspects of the structure of organizational culture.We show that old and culturally uniform organizations are proneto cultural inertia, that is, they are reluctant to adopt adifferent culture in response to a change in the environment.Cultural uniformity can be beneficial because the associatedinertia ex post protects and therefore ex ante encourages culture-specificinvestments by agents. We also explore the model's implicationsfor such issues as cultural uniformity within an organization,cultural heterogeneity across organizations, the destabilizingeffect of growth and mergers, and the conflicts arising in themanagement of culture.

我国制造业西移的成因和对策建议

实施西部大开发战略以来,西部地区的制造业出现了崛起的新迹象。但如果对西部大开发战略实施过程中的一些步骤、政策的设计或处理失当,尤其是对刚刚出现的制造业西移的现象关注不够,就会在实施中产生一些消极的影响,还会阻碍西部大开发战略的顺利实施。因此,加强对我国制造业西移现象的研究将成为一个迫切的任务。     

Strategic Environmental Standards, Wage Incomes and the Location of Polluting Firms

The purpose of this paper is tostudy how the choice of environmental standardsby governments is affected by the existence ofwage incomes when firms locations areendogenous. In developed countries labor isunionized, which allows positive wage incomesto arise. Thus, each government has incentivesto persuade firms to locate in its countrysince social welfare depends on suchincomes. But, as pollution damages theenvironment, each government will only try toattract polluting firms to thecountry, to obtain the wage incomes, whenthe valuation of environmental damage showsthat it is low.     

Employment shifts, economic reform and the changes in public/private sector wages in Mexico: 1987–1997

Over the last decade, the public sector in Mexico experienced substantial fiscal reform, divestiture of public enterprises, and the elimination of many regulations affecting pay and employment. This study analyzes the changes in the public/private sector differences in wages during the 1987–1997 period. The results from analyzing microdata from the Encuesta Nacional de Empleo Urbano show that relative public sector wages increased from 1987 to 1997. Most of the relative wage increase in the public sector can be explained by increases in the price of skills and by changes in sorting across sectors. The results have important public policy implications since they suggest that public sector workers earn more and their wages have grown faster than those of their private sector counterparts. As such, policies contemplating public sector reform should take into account the effect of these measures on the inter-sectoral income distribution and the overall economic growth.

中国上市公司债权对公司绩效影响的实证研究

关于债权的治理效应，代理成本理论和控制权理论都认为，企业资本结构中一定的负债有利于公司治理效率的提高。本文以2002～2004年度沪市上市公司为样本（样本总量为2284组数据），对我国上市公司的债权治理效率进行了实证分析。结果表明，我国上市公司负债对其绩效有重要影响：债权比例与公司绩效在统计上呈显著的负相关关系，即上市公司的负债比例越大，其绩效也会越差，公司绩效与负债还存在着显著的二次关系，当资产负债率（DAR）为21．79％时，若其他条件不变时，债权对公司绩效促进作用最大，超过这一比例，债权与公司绩效呈负相关。本文对这一结果进行了原因分析，并提出了政策建议。
