Two‐sample nonparametric estimation of intergenerational income mobility in the United States and Sweden

We estimate intergenerational income mobility in the US and Sweden, using a new nonparametric approach. The approach addresses several empirical issues raised in the literature and applies when other estimators are infeasible. We argue that previous estimates of income mobility conceal the heterogeneous nature of the transmission mechanism by keeping mobility constant across families. The striking differences we find between mobility patterns across family backgrounds, captured by father's education, lead us to question the conventional result that intergenerational transmission of earnings is weaker in Sweden than in the United States, for important parts of the population.     

几种激励理论在薪酬管理中的应用

激励理论在薪酬管理中有着直接的应用,在制定薪酬政策时必须遵循这些理论所提出的一些观点。应该在薪酬管理中充分运用这些理论,以提高我们薪酬管理的质量。公平理论、双因素理论、期望理论等激励理论也要经常应用。     

过度竞争、进入壁垒与流通组织优化

过度竞争是流通产业健康运行的重要障碍。文章从产品同质性和产品差异化两个角度,运用扩展的伯川德模型和萨洛普模型,分析了过度竞争在流通产业中出现的必然性,即流通产业自由进入的特点决定了过度竞争的存在。然后运用斯塔尔博格模型,采用跨期分析,指出了流通企业选择合适的投资水平可以阻止潜在进入者,避免过度竞争的发生。最后,提出了优化流通组织的建议。     

论微观经济基础下增值税转型的理想选择

本文从微观经济角度研究理想状态下企业对不同类型增值税的选择.研究表明,理想状态下,收入型与消费型增值税对企业利润的影响无差异且优于生产型增值税;而不同类型增值税对企业净现金流的影响优化排序是消费型、收入型、生产型,且生产型增值税的价外计税方法优于价内计税方法.总之,消费型增值税是企业的理想选择.     

Taking Actively Advantage of MNCs’ Presence

In this paper, not only do we posit that the presence of a multinational corporation may entail significant benefits for the host economy and local firms’ performance, but also that these benefits can be actively sought and dynamically reinforced by local firms through the development of intense, embedded customer–supplier relationships. Building on the relational view, we argue that this may happen through the commitment of resources to relation-specific investments. Our hypotheses find support in a sample of SMEs suppliers of ST Microelectronics, the fourth largest producer of microelectronic components in the world. We show that by making relation-specific investments, local firms can grow quantitatively and qualitatively, improve their innovativeness, and acquire new clients.

工程项目四要素集成管理能力评价体系研究

集成管理是确保工程项目取得成功的重要工作,而其核心则是项目范围、质量、成本和时间这四要素的集成管理。由于管理能力是实现管理工作的关键,因此本文以研究工程项目四要素集成管理能力的影响因素为主要内容。基于已有的研究成果进行问卷设计,通过对问卷调查数据进行因子分析,找出了工程项目过程管理能力、组织管理能力和信息管理能力三个维度所涉及的影响因素。进而通过相关性分析明确了三个维度之间的关系,最终给出了工程项目四要素集成管理能力的构成要素及内部结构,从而为开展该能力的评价提供了理论基础。     

Verti-zontal differentiation in export markets

Many trade models of monopolistic competition identify cost efficiency as the main determinant of firm performance in export markets. To date, the analysis of demand factors has received much less attention. We propose a new model where consumer preferences are asymmetric across varieties and heterogeneous across countries. The model generates new predictions and allows for an identification of horizontal differentiation (taste) clearly distinguished from vertical differentiation (quality). Data patterns observed in Belgian firm–product level exports by destination are congruent with the predictions and seem to warrant a richer modelling of consumer demand.     

矿产资源“走出去”进入非洲的形势及建议

文章分析了非洲矿产资源分布、投资环境及优势矿产资源对我国的可供性,总结了我国矿产资源走入非洲勘查开发的形势和取得的成效及找矿成功模式。我国实施非洲矿产资源勘查开发战略的对策建议:(1)建立以重点支持的矿种为基础的非洲矿产供应长效机制和以重点支持区域为保障的非洲资源配置体系;(2)要从总体思路、区域选择、勘查开发、企业运作四方面做战略部署;(3)以大型矿业企业为核心建立整体产业链(群),树立合作共赢的理念,开展中长期规划,加强技术创新;(4)加强政府引导,制定非洲矿产资源勘查开发战略,构建技术信息交流平台,开展非洲重要成矿区带成矿规律研究,建立优势矿产资源潜力评价体系。
