Learning by doing,spillovers and shakeouts

This paper studies industry evolution driven by non strategic learning by doing and spillovers. We characterize a dynamic process of cost and output changes and its effect on welfare and industry profits. The paper gives conditions for shakeouts to occur and analyzes the key factors affecting these conditions. Since shakeouts could lead to a long-run social loss due to higher market concentration, there is a role for a government to play in limiting unnecessary shakeouts. The most effective way to do so is to enhance spillovers.JEL Classification: L11, L13, O31Correspondence to: Michael TroegeWe would like to thank Hans Mewis, Christophe Moussu and an anonymous referee for valuable comments and suggestions.

Reinforcing the Link Between Contributions and Pensions: The Effect of the Population Aging

In this paper, we analyze a majority voting process on the earnings-related part of pension benefits in a Social Security system with flexible retirement. We show that the aging of the population may make it easier to implement one of the proposed reforms to achieve a delay in the average retirement age of workers, to reinforce the link between contributions and pensions.     

中美审计结果公告制度实施环境的比较及启示

审计结果公告在发达国家是一种通行做法,近年来我国也颁布了相关的法律法规,但完整的审计结果公告制度尚未建立。审计结果公告制度的建立是一个系统工程,受政府信息公开程度、审计模式、审计规范体系等环境因素的影响和制约。文章从以上环境因素着手,分析比较了中美审计结果公告制度的异同,以期对我国审计结果公告制度建立和健全提供参考。

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.

人力资本、财务资本与资本结构：理论和实证

当今社会已经从工业经济迈进知识经济时代，现有以财务资本为研究对象的资本结构理论在解释咨询、高新技术等人力资本较为密集的公司时难免会捉襟见肘。视企业为财务资本与人力资本共同的投资组合是现代资本结构理论研究刻不容缓的任务。本文以现有财务资本结构的研究为基础，通过引入人力资本变量拓宽现代资本结构的内涵，构造债务、股权和人力资本三者之间相互关系和作用的数理模型，结合对我国计算机应用服务业的实证分析，得出结论和启示。
