Managerial Firms,Entry, and Switching Costs

Empirical evidence shows that switching costs are important in many industries. We analyze the welfare effects of entry into markets with switching costs when firms can be run by managers and the entrant may be partially foreign-owned. We find that with profit-maximizing firms, the welfare effect of entry depends crucially on the ownership of the entrant firm. We also show that entry is less likely with managerial firms than it is with profit-maximizing firms. In the latter case, entry always reduces welfare if the share of the entrant firm owned by foreign investors is high. However, with managerial firms, entry always increases welfare.     

SCIENCE AND INDUSTRY: TRACING THE FLOW OF BASIC RESEARCH THROUGH MANUFACTURING AND TRADE

This paper describes flows of basic research through the US economy during the late 20th century. In addition, the paper studies the effect of the flows on scientific papers in industries and fields. This article differs from others in its use of measures of science rather than technology. Together, its results present a picture of the structure of basic research flows in a modern, science-intensive economy. Basic research flows are large within petrochemicals and drugs, and within software and communications. Flows of chemistry, physics, and engineering are common throughout all industries – biology and medicine are almost confined to petrochemicals and drugs; and computer science is nearly as restricted to software and communications. In general, basic research flows are more concentrated within scientific fields than within industries. Our findings concerning the production of scientific papers indicate that the effect of a 1% change in academic R&D spillovers significantly exceeds that of industrial spillovers. In addition, within-field effects exceed effects between-fields, while within- and between-industry effects are roughly equal. It follows that scientific fields limit basic research flows more than industries do, perhaps because large firms implicitly span a range of industries.

事务所地域与其对盈余管理的抑制能力

与西方发达市场相比,我国会计师事务所产生于政府挂靠体制,政府干预过多;上市公司多由国有企业改制而来,国家持股比例较多,上市公司受到当地政府保护等,使得我国的独立审计具有强烈的地域特色,本地事务所多在当地招揽客户,其审计过程明显受到当地政府的干预。鉴于此,我国政府于1999年开始要求会计师事务所与其挂靠单位脱钩,经过这几年的发展,有必要考察目前本地/异地事务所的审计质量差异是否巳消除。本文使用2002—2004年在沪深两市上市的A股公司数据,考察了会计事务所的地域特征对其盈余这理抑制能力的影响。本文使用可操控性应计的绝对值和非经常性损益的绝对值衡量上市公司的盈余管理程度,使用两步回归控制事务所的自选择偏误,结果发现,异地事务所对盈余管理的抑制能力显著强于本地事务所。     

Small firms and networks in capital intensive industries: The case of Spanish steel wire manufacturing

This article uses an interdisciplinary approach to gain a better understanding of the organization of the Spanish industry in a long-term perspective. Sociological concepts about networks, and studies about family firms from management and business history literatures, are combined to illuminate the dominance of family ownership in capital intensive industries. Popp, Toms and Wilson's work on the spatialization of resource distribution and resource dependence has been used to understand the dominance of small family firms co-ordinated by networks in the particular case study of the Spanish steel wire manufactures. The article also has important implications for questioning Casson's interpretation about the difficulties dynastic family firms may have in science-wire rod industries.     

Incentive Complementarity in China’s Rural Enterprises

Complementarity between incentive instruments is a central theme of theoretical research in industrial organization. However, despite its importance, empirical evidence on the existence of complementarities is limited. We identify complementarities between incentive mechanisms using a dataset on rural firms in China. Using a panel regression framework, we confirm that significant complementarities exist in terms of the impact of incentive instruments on the performance of firms. In order to evaluate the robustness of our results we account for unobserved differences in firm quality using fixed effects and instrumental variables regressions. Support for the complementarity hypothesis is found after controlling for unobserved heterogeneity.
