差别化竞争战略与服务增强的内在机理

国内外许多研究者都观察到了制造企业中服务收入占营业收入的比重越来越高、服务的利润贡献越来越大，这一现象即“服务增强”。本文首先将产品界定为既包括有形实体，也包括无形服务的完全产品，然后构造了一个完全信息动态博弈模型来研究这一现象。我们发现，厂商实施服务延伸实体产品差别化的竞争战略，必然导致服务增强的结果，同时，增进厂商利润与消费者总剩余。这一结论，为我国企业通过服务差别化来谋求在全球市场上的可持续竞争优势提供了理论根据。     

从奥运福娃看产品组合

本文从2008年的奥运会吉祥物的福娃入手,引出了"产品组合"的概念,在对产品组合的重新界定后,利用产品自身的差异程度和产品受外界的关注程度,建立了"产品组合模型"。并且通过大量的实例对产品组合模型进行了详细的介绍,最后将产品组合运用到了城市的营销和公共关系领域,对城市的发展有实际的借鉴意义。

价格战成因的再认识--以我国家电企业为例

关于价格战成因的观点很多,如供过于求论、易进难出论、产品同质论、价格敏感论等,它们都存在一些缺陷。消费者觉察“产品利益”无差异的产品实际出现供过于求或预期供过于求应是价格战形成的关键因素,它与其他因素一起促成了大多数的价格战。     

Job mismatches and career mobility

Does over-education assist or hinder occupational advancement? Career mobility theory hypothesizes that over-education leads to a higher level of occupational advancement and wage growth over time, with mixed international empirical evidence. This paper re-tests career mobility theory directly using a rich Australian longitudinal data set. A dynamic random effects probit model is employed to examine upward occupational mobility, considering two-digit occupational rank advancement and wage growth over three-year intervals. The ‘Household, Income and Labour Dynamics in Australia’ data across nine years are employed, and a Mundlak correction model is adopted to adjust for unobserved heterogeneity effects and potential endogeneity, both of which are important to over-education analysis. Contrary to career theory, the results point to job mismatch as an economic concern rather than a passing phase, regardless of whether or not workers are skill-matched. Results further show the importance of adjusting for endogeneity.     

Trade liberalization,production organization and informal sector of the developing countries

The paper provides an explanation of recent empirical evidence on fragmentation and the expansion of the informal sector in India. We argue that as the prospect of getting a better price in the international market increases, the producers in the formal sector act more like merchants and subcontract production activities to the producers in the informal sectors. Expanding production in the informal sector allows the firm to take advantage of a growing export market. Our theoretical model explains such organizational change in terms of allocation of monitoring effort between marketing and production. The existence of a low-wage informal sector facilitates division of labor and specialization in the formal segment.

企业创新投资决策的资本结构条件

本文专门考察资本结构是否以及如何对企业的创新投资产生影响,这对探寻企业融资与企业产品市场表现之间的关系有非常重要的意义。为此,论文以一个两阶段的最优化模型为分析工具,结果表明：高负债的企业将会做出相对谨慎的创新投资决策,而这会导致它在于对手的“产品差异化”竞争中居于劣势。本文得出这样的结论主要是基于两个前提：一是当企业的经营环境较好时,创新投资的边际收益较低;二是有限责任公司制度下公司对其负债承担有限清偿责任。模型的分析结果与该领域内的经验研究结论是相吻合的。     

Engineered nanomaterials: risk perception,regulation and insurance

Concerns surrounding the health risk of engineered nanomaterials, effective regulation and the lack of specifically tailored insurance products for the nanotechnology sector are putting the industry’s long-term economic viability at risk. From the perspective of the underwriter, this article speculates on the relationship between risk perception, regulation and insurability. In the nanotechnology sector, regulators are currently failing to keep pace with innovation, and insurers generally lack guiding principles for underwriting occupational risk from nanomaterial exposure. Such vulnerabilities when combined with misguided risk perceptions can lead to the overpricing of risk transfer and ill-conceived regulatory initiatives, thus potentially exhausting resources and stifling innovation in the sector. In the absence of well-developed regulatory protocols, the insurance industry has, and will continue, to occupy a key role as an effective lobby in terms of improved risk management practice. We suggest that the insurance industry will increasingly rely on control banding frameworks and ‘risk mitigation at source’ methods developed in conjunction with their clients to manage severe acute diversifiable risks. Long tail risk will continue to represent a serious challenge to insurers and regulators. In the meantime, insurers will have to bridge their current needs with improvised solutions. As an example of one possible solution, we outline a framework that utilizes financial instruments to hedge an insurer’s exposure to uncertain estimates of these long-term risks.
