安然事件引发的对公司管理层坦诚度的思考

公司的发展与财务密不可分 ,并且公司财务有理性与非理性之分。简单的说 ,公司财务的理性是指公司的发展决策以公司的流动性为依据 ,谋求公司长远利益的最大化 ,公司财务的非理性是指决策偏离了公司财务的流动性 ,过分追求市场流动性 ,注重公司当前利益 ,从长远上看 ,却使公司财务陷入危机 ,甚至导致公司破产 ,公司决策一般由管理层 (尤其是公司的高层管理人员 )作出 ,所以要保持公司财务的理性发展 ,管理人员的坦诚度非常重要。结合最近美国财务丑闻的接连发生 ,作者认为公司管理层缺乏坦诚度以及伴随发生的公司财务的非理性发展是重要原因…     

行为公司财务的最新发展及其启示

行为金融学目前已逐渐成为金融学研究中的一个重要领域,在它的影响下,公司财务领域内也形成了行为公司财务的研究范式。与经典的公司财务理论相比,行为公司财务引入了行为因素的影响,它认为外部市场的非有效性和内部管理者的非理性影响着公司的财务决策和公司价值最大化的行为。文章简单总结了行为公司财务的最新研究进展,也就是市场的非有效性和管理者的非理性对公司的融资政策、投资政策、股利政策和并购行为等各方面的影响。针对目前我国资本市场的非有效性,文章认为在我国上市公司的财务研究中应该引入行为公司财务的理论范式和研究方法,才能使得研究前提和结果符合我国的实际经济情况。

流动性、资本结构与公司绩效研究——基于扩展C．Cobb—P．Douglas生产函数的实证分析

本文基于扩展C．Cobb—P．Douglas~产函数,对房地产上市公司资本结构和公司绩效在流动性约束条件下关联进行了研究。结果发现,宏观流动性对公司绩效的影响存在即期效应,而内部流动性对绩效影响存在延期递增效应。同时在宏观流动性不变情况下,公司内部流动性对资本结构影响只存在即期效应,并且这种效应呈现累积下降趋势。

公司流动性价值的复合实物期权定价法研究

公司流动性是指公司或企业持有的流动性资产,它除了账面价值外,还含有某种潜在价值。对公司流动性价值进行科学的评估,对于投资者、公司管理者等各方都非常重要。采用实物期权理论对公司流动性进行定价,是目前公司金融理论的前沿课题。本文首次揭示了公司流动性的复合实物期权性质,并用复合实物期权模型进行了定价的尝试,为公司财务管理决策提供了一种量化的工具。     

公司投资冲击是否影响股票流动性——基于中国A股市场的经验证据

在宽松货币政策逐步退出、市值管理日益引起关注的背景下,股票流动性问题成为当前的研究热点。本文立足中国资本市场实际,实证研究了公司投资对股票流动性的影响及作用机理。研究发现:中国A股上市公司投资冲击显著降低公司股票的市场风险水平、增强股票流动性;在公司投资冲击增强股票流动性的作用过程中,公司市场风险具有部分中介作用。本研究在一定程度上厘清了微观公司投资影响股票流动性的作用机理,丰富了有关股票流动性微观前置影响因素研究。最后,就信贷资源配置结构、投资者教育及公司投资评价内容和公司市值管理等提出了政策建议。     

The role of banking regulation in an economy under credit risk and liquidity shock

This paper develops a Dynamic Stochastic General Equilibrium model which includes a financial sector to analyze the effects of liquidity shock and credit risk in the Brazilian economy. Banks use equity capital and deposits from agents to finance investments of the productive sector. The sources of financial frictions are default rate and liquidity shock, due to deposits withdrawn in advance. The banking supervisor injects liquidity in the deposit market. Using data for the Brazilian economy in the period from 1995 to 2009, the structural parameters are estimated by Bayesian methods. Impulse response functions are computed to describe the dynamic effects of exogenous shocks. The major results show that credit risk is pro-cyclical and default risk depends on structural features. The banking regulator is able to set up a policy to promote financial stability and efficiently reduce fluctuations in the output.     

The problem of private under-investment in innovation: A policy mind map

This paper reviews the major finance-related causes of private under-investment in innovation and the consequent alternative choices for public policy. The focus is on (i) incentive-based arguments that address the problem of limited appropriability of new knowledge, and (ii) the lacking access to external sources of finance caused by imperfections in the capital market. Drawing a policy mind map, which aims to enhance the mutual awareness and coordination of policy makers at the crossroads of technology and corporate finance, the paper is organised along the following chain of thought: (i) causes and rationales, (ii) aims and targets, (iii) critical constraints, and (iv) the main finance-related instruments of innovation policy.     

Do voluntary disclosures of bad news improve liquidity?

Can managers improve market liquidity and lower the cost of capital by providing voluntary earnings guidance? This study examines the impact of profit warnings on market liquidity and finds that voluntary disclosure of bad news actually improves market liquidity. By conducting an empirical study over the period 1995–2010 on NYSE, NASDAQ and AMEX listed firms, we find that firms that issue profit warnings show enhanced market liquidity during the post-announcement period. We show that profit warnings reduce information asymmetry and lower bid-ask spreads and increase trading volumes. These results are invariant to daily (short run) and monthly (long run) data after controlling for firm specific attributes. The results have major corporate policy implications. By voluntarily disclosing negative earnings guidance by managers, firms will experience significant improvement in market liquidity, thereby lowering the cost of capital. Our results are even more profound for firms that release bad news with extremely negative stock market impact. In other words, voluntary disclosure of bad news is good for market liquidity.     

流动性风险对我国公司债券信用利差的影响——基于次贷危机背景的研究

基于2007年4月至2009年9月的周数据,就次贷危机时期流动性风险对我国公司债券信用利差的变化进行了实证研究。结果表明,公司债券信用利差的变化与非流动性指标之间存在稳定的正相关关系,且在控制其他变量之后该结果依然是稳健的,说明流动性风险已融入我国公司债券信用利差中。尤其是在次贷危机背景下,流动性风险对信用利差的影响显著增强了。     

Disclosure, Corporate Governance and Foreign Share Ownership on the Zimbabwe Stock Exchange

We investigate the association of foreign share ownership with firm‐level disclosure and corporate governance structures in Zimbabwe, a developing country in Southern Africa. Our motivation for the study derives from the literature, which suggests that foreign investors: (1) generally have a preference for companies in which they are well informed and where their investments are more likely to be protected, and (2) avoid companies in developing countries because of weak corporate governance structures and low disclosure. Using data drawn from companies listed on the Zimbabwe Stock Exchange, we examine the effect of disclosure and corporate governance on foreign share ownership. We find that disclosure, proportion of non‐executive directors, institutional share ownership and audit committee independence are all positively and significantly associated with foreign share ownership. Our results also demonstrate that market capitalization, return on equity and liquidity ratios are significantly associated with foreign share ownership. These results are consistent with the notion that foreign investors have a preference for companies with effective corporate governance structures, companies with less information asymmetry, as well as companies with healthy cash positions. The results have implications for policy‐makers in developing countries in their endeavour to improve liquidity on stock markets through the participation of foreign investors. The results are also useful to managers in developing countries who are keen to increase the market value of their company, thereby reducing their cost of capital.     

数字金融如何影响企业现金持有？

基于2011—2020年中国上市企业数据和城市层面的数字普惠金融指数,考察了数字金融对企业现金持有的影响。研究发现,数字金融发展显著增加了区域内企业的现金持有,且数字金融分指标中除了覆盖广度和数字化程度外,二级指标中的数字支付和互联网信贷业务均会显著增加企业现金持有。进一步分析发现,数字金融通过提高经营活动现金流、抑制企业杠杆率和降低债务融资等机制增加了企业现金持有。此外,对于规模较小、民营和弱银企关系的企业而言,数字金融对企业现金持有的影响更显著。研究结论丰富了数字金融发展的经济后果,也拓展了现金持有理论的分析框架。     

Ownership structure and corporate liquidity policy

This study analyzes the relationship between corporate liquidity (i.e. the fraction of assets invested in cash and marketable securities) and managerial ownership in the firm's stock. We postulate a negative relationship between excess liquidity and managerial stock ownership as the managers' interests shift from protecting the value of their human capital to maximizing the value of their stockholdings. This managerial behavior is constrained by the disciplining forces of the firm's product market structure and the market for corporate control. While the tests fail to reveal any significant impact of managerial stock ownership, they show that firm liquidity is positively related to the firm's ability to earn economic rents.     

商业银行经营决策对我国货币供给的影响及建议

商业银行经营行为对我国货币供给的影响作用于基础货币投放和存款货币创造两个阶段。国有控股商业银行因其垄断性地位使得信贷投放过于集中、流动性管理水平低,其他股份制商业银行不受风险约束的盲目扩张倾向,都可能造成我国货币供给和调控政策实施效果偏离预期。针对以上问题,本文建议,国有控股商业银行应加强股份制改革,建立现代企业制度;其他股份制商业银行根据自身的条件确定发展方向,有序竞争。
