公司内部治理与投资者保护

公司内部治理是公司投资者保护的重要手段,其中股权结构、董事会制度、经营者激励是组成内部治理的重要要素。本文分析了股权结构、董事会制度和经营者激励与投资者保护的关系,研究了三种关系之间的联系,并指出要统筹考虑三种关系,构建竞争型的大股东股权治理结构,培养机构投资者,完善独立董事制度,推广经营者股票期权制度,切实保护投资者利益。     

股权分置改革后全流通上市公司股权结构与公司绩效的实证分析

大小非问题汹涌澎湃,专家学者还有众多投资者都在讨论究竟是否应该股改,现在又应该如何应对大小非减持。本文将通过对全流通上市公司的股权结构与公司绩效的实证分析来探讨这个问题,并且提出应对建议,认为对于大小非减持,不鼓励,也不限制,并且应该大力支持和鼓励控股股东收购有意减持的其他大非和小非的股份。     

上市公司股权结构与资本结构选择的实证分析

以1997年12月31日以前在深沪两地上市的A股公司1998～2002年度公开数据为研究的观测值,对股权结构与资本结构的理论假说进行了实证检验。证据显示,经理人员持股和股权集中对企业资本结构的选择有显著影响。国有股和流通A股的存在对企业资本结构的选择影响较小,法人股的存在对企业资本结构的选择存在一定影响。     

所有权结构、代理成本与公司价值－来自中国上市公司的经验证据

本文从理论上分析了股权结构与公司价值间的关系,并通过实证研究考察上市公司所有权结构及由此而产生的代理成本与其市场价值之间的关系。检验结果与理论分析相一致：（1）上市公司存在控股股东,会使公司市场价值折价。（2）上市公司存在股权制衡,能够有效的减少公司代理成本,提升公司价值。（3）不同性质的控股股东所产生的代理成本不同,国家股东的非人格化使得公司的代理成本高于非国有股东。本文得出结论：我国的上市公司普遍存在控股股东,由此产生的代理成本减低了企业的价值,国有股东的代理问题尤为严重,股权制衡的模式能够在一定程度上缓解代理问题。     

非国有大股东对国企超额雇员的影响:成本效应还是激励效应

基于竞争理论的国企改革思路强调减少政策性负担摊派,基于产权理论的改革思路侧重于引入非国有资本,以解决产权不清晰与所有者缺位问题.本文尝试融合两种理论,以国企超额雇员问题为研究对象,从非国有大股东视角探究混合所有制改革成效.研究发现:非国有大股东能够显著降低国企超额雇员,减弱超额雇员对公司价值的损害作用,且该治理作用会随非国有大股东相对力量的提高而增强;从作用机制来看,该治理作用不仅表现为劳动力成本尤其是员工薪酬的节约,还表现为内部薪酬差距和管理层薪酬业绩敏感性的提高,兼具成本效应与激励效应;该作用在地区就业压力较小、劳动密集度较低以及劳动保护水平更低的环境下更为显著.     

Agency costs and tax planning when the government is a major Shareholder

In state owned enterprises (SOEs), taxes are a dividend to the controlling shareholder, the state, but a cost to other shareholders. We examine publicly traded firms in China and find significantly lower tax avoidance by SOEs relative to non-SOEs. The differences are pronounced for locally versus centrally-owned SOEs and during the year of SOE term performance evaluations. We link our results to managerial incentives through promotion tests, finding that higher SOE tax rates are associated with higher promotion frequencies of SOE managers. Our results suggest managerial incentives and tax reporting are conditional on the ownership structure of the firm.     

Institutional investors and international investments in emerging economy firms: A behavioral risk perspective

While the extant literature has examined the influence of controlling and non-controlling principals on the internationalization decisions of emerging market firms, heterogeneity among non-controlling principals is largely ignored. The risk characteristics of different groups of owners, shaped by their institutional environments, could contribute to the differences in their preferences for firm internationalization. In this paper, we draw insights from institutional theory and behavioral risk perspective to examine the risk propensities and risk perceptions of various non-controlling principals, such as pressure-resistant (FIIs and mutual funds) and pressure-sensitive (banks, insurance companies and lending institutions) institutional investors. Empirical results from a sample of 2364 unique Indian firms during the 2005–2014 time-period show that, after controlling for firm-level resources and capabilities identified in prior literature, the ownership share of different types of institutional investors is associated with firms’ international investments differently. While pressure-sensitive institutional investors, such as banks and insurance companies, are not supportive of foreign investments by firms, pressure-resistant institutional investors, such as FIIs and mutual funds, are supportive of this strategic decision. Furthermore, our results show that the family ownership in a firm (measured in terms of family shareholding) further lowers the preference of pressure sensitive institutional investors for internationalization, whereas family ownership positively moderates the pressure resistant investors towards internationalization.     

The impact of prudential toolkits on loan growth in Central and Eastern European banking systems

This paper examines the effects of prudential policy on loan growth in 11 Central and Eastern European banking systems, spanning the period from 2000 to 2015. Based on the measures taken by the authorities of our sample countries, we build several prudential indices. Additionally, we control for the effects of several country-specific factors and bank-specific characteristics. Finally, we test the homogeneity of these effects, accounting for cycle, ownership, and bank effects. Generally, the empirical findings reveal a negative correlation between prudential toolkits and credit growth, with a conspicuous impact for tools targeting lending activity. We see that the effects of a change in the lending framework on loan growth are heterogeneous when we account for crisis and cycle patterns. Furthermore, the interaction between ownership and crisis reveals that, in normal times, foreign banks recorded higher loan growth compared to domestic banks. The opposite is true in turbulent times. The analysis of interactions between credit-based measures and bank-specific variables show that the effects of prudential actions depend on the bank size and leverage.     

Conditional Mandates on Management Earnings Forecasts: The Impact on the Cost of Debt

Exploiting a unique conditional disclosure mandate on management earnings forecasts (MEFs) in China, we examine the differential effects of voluntary and mandatory MEFs on the cost of debt. We find that firms providing voluntary MEFs have lower cost of debt than do mandatory forecasters and nonforecasters. The results of the channel analyses reveal that voluntary forecasters have greater commitment to voluntary MEFs in future periods than do mandatory forecasters and nonforecasters, and the precision, accuracy, and timeliness of MEFs are higher for voluntary forecasters than for mandatory forecasters. Additional analyses show that the differential effects of voluntary and mandatory MEFs on cost of debt are stronger for voluntary forecasters operating in opaque information environments, issuing high-quality and confirming forecasts, controlled by private shareholders, and operating in highly competitive product markets. Overall, our results indicate that, compared with mandatory MEFs, voluntary MEFs are more informative for credit investors, particularly for firms facing greater information risk and operating uncertainty.     

集权式股权结构会影响信息技术企业创新吗——非执行董事的中介效应

中国企业普遍具有高股权集中度。基于双重委托代理理论，以Osiris和CSMAR数据库中国信息技术类全球上市公司为样本，研究不同集权式股权结构对企业创新的差异化影响，以及非执行董事在二者关系中的作用机制。结果显示，绝对集权式股权结构更易形成控股股东的“支持效应”和大股东间“同舟共济”，体现为保守的创新投入和较高的创新产出；相对集权式股权结构更易形成控股股东的“掏空效应”和大股东间“同床异梦”，体现为较高的创新投入和较低的产出。基于中介效应机制的研究表明，非执行董事对创新投入的决策效应不显著，但对创新产出的“监督效应”显著，且非执行董事具有显著中介效应。进一步分析表明，两职分离能够抑制相对集权式企业控股股东的“掏空”行为；家族企业在相对集权式股权结构下的“掏空效应”和“同床异梦”更明显。
