风险厌恶测定与我国银行治理效率的实证研究

基于FDIC对商业银行贷款损失所设定的概率分布,本文利用VaR方法对商业银行风险厌恶程度进行了测定,并利用我国上市银行2004～2008年间的财务数据对商业银行的风险厌恶程度进行了实证分析,结果表明商业银行的风险控制可以反映其风险厌恶程度,风险厌恶程度在风险控制中得到充分体现.银行的风险厌恶程度越高,净资产回报率越高.     

国有资本参股影响民营企业绿色创新的偏向性——促进实质性创新还是策略性创新？

采用沪深A股非金融类民营上市公司2009—2022年数据的分析发现,国有资本参股对民营企业绿色创新的促进作用具有明显的偏向性,即显著促进了实质性绿色创新,而对策略性绿色创新的影响不显著。机制分析表明：国有资本参股程度提高有助于民营企业获得更多的环保补助和政府补贴;环保补助（政府补贴）增加可以显著促进民营企业实质性和策略性绿色创新,且对策略性绿色创新的促进作用更大;国有资本参股对环保补助（政府补贴）促进民营企业实质性和策略性绿色创新分别具有显著的正向和负向调节作用。因此,国有资本参股具有资源获取效应和治理改善效应,可以帮助民营企业获得更多的创新资源,也能够缓解委托代理问题,进而在促进民营企业绿色创新的同时形成实质性创新偏向。进一步的异质性分析表明,国有资本参股促进民营企业绿色创新的偏向性在绿色发展意愿较弱、非重污染行业、环境规制强度较小地区的民营企业中更为明显。应在持续推进企业混合所有制改革的同时,重视并解决好企业的委托代理问题,提高民营企业的绿色发展意愿,促进民营企业绿色创新的质量提升。     

What Drives the Property Price-Trading Volume Correlation? Evidence from a Commercial Real Estate Market

The significant price-trading volume correlation found in the residential property market presents a challenge to the rational expectation hypothesis. Existing theories account for this fact with either capital market imperfection (down-payment effect or loss-aversion consideration) or imperfect information (search theoretic models). This paper employs data from a commercial real estate market, which face a different degree of severity of capital market constraint than the residential market, and thus provide an indirect but effective test for alternative theories. Policy implications are also discussed.     

The consequences of managerial indiscretions: Sex,lies, and firm value

Personal managerial indiscretions are separate from a firm's business activities but provide information about the manager's integrity. Consequently, they could affect counterparties’ trust in the firm and the firm's value and operations. We find that companies of accused executives experience significant wealth deterioration, reduced operating margins, and lost business partners. Indiscretions are also associated with an increased probability of unrelated shareholder-initiated lawsuits, Department of Justice and Securities and Exchange Commission investigations, and managed earnings. Further, chief executive officers and boards face labor market consequences, including forced turnover, pay cuts, and lower shareholder votes at re-election. Indiscretions occur more often at poorly governed firms where disciplinary turnover is less likely.     

Quantifying corruption by a human capital earnings equation

This paper uses a human capital earnings equation to quantify administrative corruption in the public sector. Regression analyses are conducted based on information from surveys administered to public officials in Albania. After accounting for officials’ characteristics, e.g., schooling, experience, gender, type of agency, and public and private sectors’ features, we deduce that the administrative corruption was on average 2.6× the officials’ current salary in Albania, which is equivalent to 16.7% of the country’s GDP.

政府控制、治理环境与公司价值--来自中国证券市场的经验证据

本文承袭刘芍佳、孙霈和刘乃全( 2 0 0 3 )一文所使用的“终极产权论”,根据上市公司披露的终极控制人数据,首次将上市公司细分为非政府控制(即民营、乡镇或外资资本控制)、县级政府控制、市级政府控制、省级政府控制以及中央政府控制这五种类型。同时,我们利用樊纲和王小鲁( 2 0 0 3 )编制的中国各地区市场化进程数据及其子数据构建各地区公司治理环境指数。在此基础上,我们以2 0 0 1年至2 0 0 3年期间的上市公司为样本,对政府控制、治理环境与公司价值的关系进行了实证分析。研究发现,政府控制尤其是县级和市级政府控制对公司价值产生了负面影响,但公司所处治理环境的改善有助于减轻这种负面影响。其政策含义是,解决中国上市公司的公司治理问题,不仅需要继续“抓大放小”,还需要从根本上改善公司治理环境。对研究者来说,需要把目光转移到影响公司治理的根本因素上来,加强对公司治理环境的分析。     

社会资本对企业资本结构周期性变动幅度的影响——基于中国上市公司的实证检验

以2005—2014年中国沪深两市A股全行业上市公司为样本,实证检验了企业资本结构的周期性变动特征,以及社会资本对不同所有权性质企业的资本结构周期性变动幅度的影响。结果表明:企业的负债水平总体上呈顺周期变动特征,但国有所有权会减小企业资本结构的顺周期变动幅度;高水平社会资本降低了高负债水平民营企业资本结构的顺周期变动幅度,提高了低负债水平国有企业资本结构的顺周期变动幅度;民营企业资本结构的顺周期变动幅度过大且高于最优变动幅度;国有企业资本结构的顺周期变动幅度过小且低于最优变动幅度;社会资本起到降低民营企业资本结构顺周期变动幅度、提高国有企业资本结构顺周期变动幅度的作用,从而促使各类企业的资本结构向其最优水平回归,即高水平社会资本具有优化企业资本结构的作用。

I Feel Your Pain: The Effect of Regulator as a Minority Shareholder on Merger and Acquisition Performance

We examine the effect of a regulator-led advocate for minority shareholders on merger and acquisition (M&A) performance in China. In recent years, the China Securities Regulatory Commission established the China Securities Investor Services Center (CSISC), which began its ownership of 100 shares of public firms in 2016. The CSISC advocates for the interests of minority shareholders proactively. Focusing on abnormal stock returns in M&A announcements, we find that acquirers that have the CSISC as a shareholder (CSISC acquirers) exhibit higher positive abnormal stock returns than non-CSISC acquirers. Cross-sectional analysis suggests that the core results are mainly driven by firms with severe agency problems and weak external/internal monitoring, and those not controlled by the state. In addition, we find that CSISC acquirers have better long-term performance and encounter more M&A failures than non-CSISC acquirers. Our findings indicate that although the CSISC only holds 100 shares of listed companies, it plays an effective role in monitoring and driving firms to make appropriate M&A decisions.     

关于完善公司治理结构的思考

笔者认为深化国有企业改革,大力推进企业的体制、技术的管理创新,其核心是产权改革。改革成败的关键是完善公司治理结构。本文通过对我国公司治理结构现状的分析,提出了完善公司治理结构与治理机制的对策。
