环境不确定性、多元化经营与资本成本

以2007-2013年的上市公司为研究对象,考察新兴市场中的微观环境因素如何影响企业的经营战略以及两者的交互作用对资本成本的影响。研究表明,环境不确定性与企业资本成本显著正相关,进一步发现,随着环境不确定性的增加,企业多元化经营程度呈现先升后降的趋势,而资本成本则随着多元化经营程度增加呈现先降后升的趋势。研究结果说明,在转型经济环境下,微观环境的不确定性加剧了企业与投资者和债权人之间的信息不对称程度,增加企业的资本成本,而企业实施多元化经营降低环境不确定性对企业资本成本不利影响的作用是有限度的。     

多元化与资本成本的关系——来自中国股票市场的证据

根据期权定价模型,多元化降低了公司风险,但其受益者是债权人,而不是股东,这使得公司部分财富从股东手中转移到债权人手中,由此降低了股东财富,因此,多元化可能并不为股东所欢迎,从而多元化公司的权益资本成本可能高于专业化公司。同时,由于内部资本市场在公司内部的资源再配置作用,使得公司降低了对融资成本较高的外部资本市场的依赖,因此,多元化经营公司的总资本成本可能低于专业化经营公司。本文以2001—2004年我国上市公司为例,对多元化与公司权益资本成本和总资本成本之间的关系进行了实证检验。研究结果表明,多元化与权益资本成本正相关,而与总资本成本负相关。     

制度环境和权益资本成本——来自中国省际数据的比较研究

本文以中国237家非金融上市公司2004~2007年组成的平衡面板数据(共948个观察值)为研究样本,在控制相关变量的基础上,应用一系列GLS从政府关系、法律制度环境、金融市场发育程度和产品市场发育程度四个维度实证检验制度环境如何影响公司权益资本成本。实证结果表明,制度环境是影响权益资本成本的重要因素。具体而言:(1)政府关系与权益资本成本显著负相关;(2)法律制度环境与权益资本成本显著负相关;(3)金融市场发育程度与权益资本成本显著负相关;(4)产品市场发育程度与权益资本成本显著负相关。     

企业税收规避与权益资本成本

本文以2008～2015年沪深A股上市非金融企业为研究样本,结合机构投资者异质性对企业税收规避与权益资本成本间的关系进行实证检验。研究发现:企业税收规避程度越高,其权益资本成本也相应提高;经营绩效是税收规避影响权益资本成本的一个中介路径,即高程度的避税活动会损害企业的经营绩效从而提高权益资本成本;结合机构投资者异质性发现,相比交易性机构投资者,稳定性机构投资者更能发挥治理作用,弱化税收规避对权益资本成本的负面影响。本文的研究丰富了税收规避与权益资本成本方面的研究,为新兴加转轨时期我国上市公司避税行为的经济后果提供了新的经验证据,同时也可为企业、政府和机构投资者提供一定的参考。     

董事高管责任保险、权益资本成本与上市公司再融资能力

基于公司治理角度,使用2002~2012年沪深引进董事高管责任保险的上市公司为样本,考察了董事高管责任保险、权益资本成本和上市公司再融资能力三者之间的相互关系。研究表明：董事高管责任保险与上市公司的再融资能力负相关,与权益资本成本呈显著正相关关系;权益资本成本在董事高管责任保险和上市公司再融资能力影响机制中发挥中介作用。具体地,投资者因规避责任保险机制庇护下公司高管自利行为可招致的风险,导致上市公司权益资本成本增加,从而降低了公司再融资能力。     

董事高管责任保险、权益资本成本与上市公司再融资能力

基于公司治理角度,使用2002~2012年沪深引进董事高管责任保险的上市公司为样本,考察了董事高管责任保险、权益资本成本和上市公司再融资能力三者之间的相互关系。研究表明:董事高管责任保险与上市公司的再融资能力负相关,与权益资本成本呈显著正相关关系;权益资本成本在董事高管责任保险和上市公司再融资能力影响机制中发挥中介作用。具体地,投资者因规避责任保险机制庇护下公司高管自利行为可招致的风险,导致上市公司权益资本成本增加,从而降低了公司再融资能力。     

市场化进程、自愿性信息披露和权益资本成本

基于市场化进程中政府对企业干预程度的差异,本文研究市场化进程对自愿性信息披露与权益资本成本关系的影响。研究发现,市场化进程对自愿性信息披露与权益资本成本的负相关关系起加强作用;更进一步地,在市场化进程较低的地区,受较强的政府干预的影响,国有上市公司比非国有上市公司自愿性信息披露与权益资本成本的相关关系更弱,相反,在市场化进程较高的地区,政府会减少对企业的干扰,非国有上市公司相比于国有上市公司对这种影响的弹性更大,表现在非国有上市公司比国有上市公司更能通过披露较多的自愿性信息来降低权益资本成本。     

环境不确定性、客户集中度与权益资本成本

客户是企业重要的外部利益相关者,对企业生产经营的诸多方面存在影响,现有探讨客户经济后果的文献已较为丰富,却鲜见关注客户影响企业权益资本成本的研究。对我国2007-2014年A股专业化经营的制造业上市公司的实证分析显示:企业的客户集中度与其权益资本成本显著负相关,但这种显著的负相关关系只在环境不确定性较低时存在。此结果说明,在我国特定的市场环境中,大客户的存在被认为有利于促进供应链整合,改善企业经营状况,降低企业风险,并向市场传递积极信号,从而能降低企业的权益资本成本,但由于企业所面临市场形势的差异,客户集中度对其权益资本成本的影响存在异质性。     

企业社会责任信息披露与权益资本成本

运用理论分析和实证检验的方法从权益资本成本的角度研究我国上市公司企业社会责任信息披露的经济动机.研究发现:上市公司上期权益资本成本越高,本期披露社会责任报告的可能性越大,说明降低权益资本成本是上市公司决定是否披露社会责任报告的重要经济动机;对于首次披露企业社会责任报告的公司,上期权益资本成本越高,本期社会责任信息披露质量越高;但对非首次披露企业社会责任报告的公司来说,披露企业社会责任报告的资本成本动机不显著.     

资本结构对房地产上市公司经营业绩的影响

近年来房地产行业在我国的蓬勃发展,充分证明其作为支柱产业的稳固性。而资本结构是公司治理的基础,一个合理的资本结构对降低资本成本、提高公司经营绩效有着重要的作用。通过采用Eviews统计软件对50家房地产上市公司10年的相关数据进行回归分析处理得出回归模型,由此作出结论:权益乘数与公司经营业绩成负相关关系;而总资产周转率和利率与公司经营业绩成正相关关系。最后根据模型分析结论提出五条建议,即:减少债务融资,拓宽融资渠道;提高资金使用效益、避免盲目筹资;改善银行与企业之间的关系;建立健全的往来款管理体制;提高资产流动性。     

Climate risk: The price of drought

We document a significant positive relation between drought risk and the cost of equity capital. Our estimation shows that the cost of equity capital is 92 basis points higher for firms affected by severe drought conditions. We provide evidence that when firms are affected by droughts, firms with higher local institutional holdings exhibit a higher cost of equity capital. This result supports the well-known local bias of institutional investors, and suggests that diversification cannot fully eliminate the loss in wealth caused by droughts. Consistent with theoretical predictions, we find that drought duration and drought intensity further increase a firm's risk premium. However, for firms with diversified cash flows/investments, geographically dispersed business operations, and high cash holdings, the impact of drought on the expected return is significantly lessened. Overall, our findings show that investors require a higher rate of returns on firms affected by droughts and offer implications on how firms can mitigate the impact of droughts on their cost of capital.     

The implied cost of equity capital,corporate investment and chief executive officer turnover

This study investigates how the cost of equity capital, along with corporate investment, affects chief executive officer (CEO) turnover decisions. We hypothesize that the cost of equity conveys information about firm performance uncertainty that is informative of CEO talent. Consistently, our empirical results show that the likelihood of CEO turnover is positively associated with the implied cost of equity, after controlling for earnings and stock performance measures and risk factors. Additional analysis of reverse causality supports the causal effect of the high cost of equity on CEO dismissals. We also find that the positive association is more pronounced for firms that are more likely to suffer from underinvestment problems. These results suggest that the cost of equity plays a more important role in assessing CEO performance when the firm needs more external equity capital to pursue investment opportunities.     

Firm internationalization and cost of equity: Evidence from China

This paper examines the relationship between firm internationalization and cost of equity. We find that firms with a higher degree of international operations have a significantly lower cost of equity, which is more pronounced for firms in provinces with a weak institutional environment or firms experiencing intense domestic competition. Our results are robust after adopting a firm fixed effect model, propensity score matching, difference-in-difference regressions and alternative measurements of key variables. Further, international operations help firms to break through their institutional constraints in the domestic market, which reduces the cost of equity and improves resource allocation efficiency in the capital market. Our paper enriches the literature on firm internationalization and the cost of equity from the perspective of emerging markets.     

Should banks be geographically diversified? Empirical evidence from cross-country diversification of European banks

Using a sample of European bank, this paper investigates the impact of banks' geographic diversification on their cost of equity capital. Examining the geographic diversification of European banks gives an insight on the value of cross-border banking. To measure diversification between major geographic areas in which the bank operates, the Herfindahl–Hirschman Index, based on revenues generated at home and abroad is constructed for each bank. To address the problem of endogeneity, system generalized method of moments estimator is used. The main finding of the analysis is that, other things equal, more geographic diversified banks have higher cost of equity capital than geographically focused ones. This result implies that the adverse market valuation effect of geographic diversification (increase in agency problem) dominates the positive ones (increase in efficiency and reduction in risk).     

Riding the waves of technology through the decades: The relation between industry-level information technology intensity and the cost of equity capital

This paper examines the effect that information technology (IT) investments have on the industry cost of equity capital. We find that industry IT intensity, defined as the relative amount of IT investment to total fixed asset expenditures, is negatively related to the industry cost of equity capital. These results indicate that industries with higher levels of IT investment have lower cost of equity capital. We also find that the relation between IT intensity and cost of equity capital changes over time. Initially, investors viewed IT investments as risky ventures and demanded higher levels of cost of equity (or higher return on their investment) for those industries investing in IT. However, beginning in the 1980s, as IT became more reliable, more cost effective, and had the ability to transform businesses, investors viewed IT Intensity as a positive business strategy with less associated risks and reduced their required cost of equity capital (or lower return on their investment). Extrapolating from our industry results, IT investments allow firms to potentially raise capital at a lower price so they have more assets to employ, indicating that IT investments can be a key factor for business success.     

Toward Real‐Time Financial Reporting: How to Reduce Investors' Information Gap and the Cost of Capital

Public companies are struggling to provide detailed and accurate guidance in a turbulent world. Many have dropped guidance altogether, or substantially reduced the precision of their guidance. However, they pay a price for the resulting increase in investor uncertainty in the form of a higher cost of capital and reduced equity valuations. This article provides evidence that improving investors' information can help to reduce the cost of capital of public companies. A look at market data for the years 2007 through 2009 for German DAX 30 companies suggests that investor uncertainty stemming from current financial reporting practices appears to be amplifying the expected association between increases in the beta coefficient and the volatility of fundamentals such as revenues and income, which in turn could be increasing the cost of equity capital. The article explores ways for both individual companies and financial regulators to improve investor information and reduce the cost of capital. For individual companies, the proposed solution is more frequent and voluntary provision of information about actual performance in lieu of more extensive financial guidance. A look at market data for the years 2007 through 2009 for German DAX 30 companies suggests that investor uncertainty stemming from current financial reporting practices appears to be amplifying the expected association between increases in the beta coefficient and the volatility of fundamentals such as revenues and income, which in turn could be increasing the cost of equity capital. Quarterly reporting is a matter of tradition while today's information technology could easily provide investors with real‐time, or close to real‐time, financial information. Internal financial controls, the quality of financial reporting, and the cost of capital might all be improved by mandating faster reporting cycles.     

Motives for and Effects of Asset Revaluation: An Examination of South Korean Data

Examining a sample of South Korean firms, of which 201 revalued assets and 899 did not during the period 2008–2009, we find that the average debt cost, equity cost, and weighted average cost of capital (WACC) are higher among the firms that revalued. Firms with higher equity costs and leverage are more likely to revalue and the propensity has a negative relationship with profitability, cash flow, and Tobin’s q. Firms that engage in revaluation experience reductions in all capital costs from year ?1 to +1, comparable to those among firms that did not revalue. Our results support both the information hypothesis and the debt-cost hypothesis.     

Types of investor uncertainty and the cost of equity capital

We jointly test the effects of two types of investor uncertainty, one related to future firm performance and unrelated to accruals (cash flow uncertainty) and one directly related to accrual estimation errors (accounting quality uncertainty). Distinct from prior studies, our uncertainty estimates are based on a matched‐firm design that minimizes the mechanical relationship between the two uncertainty variables. We find a strong negative relationship between cash flow uncertainty and multiple estimates of the cost of equity capital. With respect to accounting quality uncertainty, we find a strong positive association with both expected stock returns and implied costs of equity, but only in settings that control for cash flow uncertainty. Collectively, our results suggest the need to consider different types of investor uncertainty when examining how investor uncertainty affects the cost of equity capital.     

高铁时空压缩效应与公司权益资本成本——来自A股上市公司的经验证据

以往文献大多集中于交通基础设施对一国或地区宏观经济的影响,而较少关注其对资本市场的作用。本文基于信息不对称视角,考察了高铁开通改变地理距离的时空约束后如何影响公司权益资本成本。以2007—2018年A股上市公司为样本,本文研究发现,上市公司所在地开通高铁后,由于内外信息不对称程度的降低,公司权益资本成本显著下降。该现象受到一系列公司特征的影响,与多数投资者聚集地距离越远、业务复杂度越高的公司,权益资本成本受高铁开通影响而下降得更明显。进一步的研究表明,高铁开通后公司股票流动性的提升及信息披露质量的提高是影响权益资本成本的重要路径。
