会计师事务所的进入、退出与审计市场的竞争

本文主要从进入、退出的角度研究审计市场的竞争。本文的分析表明,审计市场的市场占有率变动率更为合理地衡量市场的动态变化,审计市场的进入壁垒主要是准入壁垒(管制壁垒),而结构性壁垒和流动性壁垒主要存在于大客户市场,对于小客户市场的影响作用很小。为了防止进入者的进入,在位者通过各种流动性壁垒的设置以提高进入者的成本。但从总体看,审计市场仍然是高度竞争的。     

Intra-metropolitan shifts in labor demand and the adjustment of local markets

I offer new evidence on the adjustment of local labor markets to geographic shifts in labor demand within US metropolitan areas using a unique data set in which metropolitan subregions are geographically matched across the 1970–1980 and 1980–1990 decades. The evidence uncovered paints the following picture. Workers, especially those with less education, make incomplete adjustments within metropolitan areas in response to intra-metropolitan demand shifts. Although blacks may not make especially limited adjustments, they have disproportionately suffered deleterious effects from job movements because the demand shifts have tended to be away from their places of residence.     

转型期中国宏观产权制度的形成机理

中国地方政府围绕资本形成展开竞争,导致产权改革的非均衡推进,从而演进出政府对各生产要素利益保护不一致的宏观产权制度,这种宏观产权制度在过去的30年里是极具效率的。但随着资本日益丰富以至于不再稀缺,我们有必要在进一步产权改革的基础上建立政府适度退出机制,以使政府对各生产要素的利益保护都趋于正常值水平。     

Trend and Comparative Analysis of Inequality of Social Opportunity

This article sets out a new method for the analysis of inequality of social opportunity. The shortcomings of the previous concepts and measures attempting to assess the degree of openness of the mobility process independently of marginal effects are displayed. The suggested new approach refers to relative opportunity distributions of individuals according to their social origin. Starting from the premise that these distributions underlying the observed allocation of social positions are continuous, it is assumed that it is possible to compare them using straight lines. The various slopes of the lines represent inequality of social opportunity coefficients which permit trend and comparative analysis of the mobility process net results.

Location advantages and subsidiaries’ R&;D activities in emerging economies: Exploring the effect of employee mobility

With multinational corporations increasingly seeking subsidiaries’ specific advantages in foreign countries to develop their innovative capabilities, internationalization of research and development has been greatly emphasized. However, in emerging economies, managers are encountering the challenge of high employee mobility under the weak intellectual property protection regime. This article investigates subsidiaries’ employee mobility and proposes that it negatively moderates the relationship between location advantages and the level of subsidiaries’ R&D. This article extends R&D internationalization and enhances current understanding of subsidiaries’ R&D activities. Further, it provides managerial implications as to how managers can improve R&D outcome by mitigating obstacles in emerging economies.
