Investment Horizons and Information

We examine the relation between institutions' investment horizons on firms' financing and investment decisions. Firms with larger short‐term institutional ownership use less debt financing and invest more in corporate liquidity. In contrast, firms with larger long‐term institutional ownership use more internal funds, less external equity financing, and preserve investments in long‐term assets. These results are primarily driven by the variation in informational preferences of different institutions. We argue that short‐term (long‐term) institutions collect and use value‐neutral (value‐enhancing) information.     

Information Asymmetry Around Earnings Announcements

This study examines bid-ask spreads to determine how the anticipation and release of earnings announcements affect information asymmetry in the stock market. I use regression analysis and find that bid-ask spreads are negatively related to public information availability and positively related to earnings variability and the market reaction to prior unexpected earnings. The results suggest that firms for which earnings is expected to yield a relatively larger stock market reaction have greater information asymmetry than firms for which earnings are expected to yield a smaller market reaction.I also find that bid-ask spreads gradually increase in the four days prior to earnings announcements, and increase sharply the day prior to, the day of and the day after the earnings announcements. Bid-ask spreads seven to ten days after earnings announcements are not significantly different from bid-ask spreads seven to ten days prior to earnings announcements.     

Information Asymmetry and Dual Distribution in Franchise Networks

We examine whether a dual distribution system that uses both franchisor‐operated and franchisee‐operated outlets reduces a franchisor's information disadvantage when contracting with franchisee retailers. Using detailed qualitative and quantitative managerial data, we find persuasive evidence of the strategic use of performance information obtained from franchisor‐operated outlets to reduce information asymmetry and enhance contracting efficiency for franchisee‐operated outlets. We test whether the proximity of franchisor‐operated retail outlets to franchisee‐operated retail outlets reduces underpricing of quasi‐franchise contracts. Our results accord with the proposition that information asymmetry reduces contracting efficiency and are consistent with our prediction that a manufacturer can reduce intrinsic information asymmetry by maintaining franchisor‐operated outlets that are geographically proximate to the franchisee‐operated outlets, and that this improves the franchisor's pricing of franchising contracts. We conclude that dual distribution reduces the franchisor's information asymmetry and increases their contract pricing efficiency.     

Information Asymmetry about Investment Risk and Financing Choice

Though it is generally accepted that information asymmetry has an impact on capital structure policy, the nature of the information asymmetry is not well understood. Recent theoretical work and empirical evidence suggests that financing choice depends upon the information asymmetry associated with the investment risk of the particular use of proceeds. Consistent with this view, using the sources and uses of funds framework, we find that equity is used to fund projects with greater information asymmetry about their risk such as research and development expenditure, while debt is used to fund investments with lower information asymmetry about their risk such as liquidity enhancement.     

Information Asymmetry and Corporate Investment Decisions: A Dynamic Approach

This paper develops a dynamic model of the financing and operating decisions of firms in the presence of information asymmetry. When the value of growth opportunities is not fully recognized, securities are undervalued, thus influencing the financing and investment decisions. The agency‐based underinvestment problem is re‐examined under information asymmetry. For firms with greater growth opportunities, the investment distortion resulting from information asymmetry is especially significant. Information asymmetry also increases the expected bankruptcy cost. The cost of information asymmetry in terms of both the firm value and the information spread under the optimal capital structure could be substantial.

Trading Volume, Information Asymmetry, and Timing Information

This paper investigates trading volume before scheduled and unscheduled corporate announcements to explore how traders respond to private information. I show that cumulative trading volume decreases inversely to information asymmetry prior to scheduled announcements, while the opposite relation holds for volume after the announcement. In contrast, trading volume before unscheduled announcements increases dramatically and shows little relation to proxies for information asymmetry. I investigate the behavior of market makers and find that they act appropriately by increasing price sensitivity before all announcements, implying that they extract timing information from their order books.     

Institutional Investment Horizons and the Cost of Equity Capital

We examine the influence of institutional investors’ investment horizons on a firm's cost of equity. We argue that the cost of equity will decrease in the presence of institutional investors with longer‐term investment horizons due to improved monitoring and information quality. Our empirical results demonstrate that the cost of equity declines in the presence of institutional investors with long‐term investment horizons, all else remaining equal. Our results indicate also that the monitoring role of long‐term institutional investors is more pronounced for firms with higher agency problems (poorly governed firms). Overall, our evidence suggests that when considering the influence of institutional investors, it is critical to account for institutional heterogeneity, which leads to new directions for future research.     

Information Asymmetry and the Dealer's Bid-Ask Spread: A Case Study of Earnings and Dividend Announcements

Recent theoretical work on the bid-ask spread asserts that the dealer should widen the bid-ask spread when he or she suspects that the information advantage possessed by informed traders has increased. Thus, the dealer's spread can be employed to test for an increase in information asymmetry prior to an anticipated information event. In this paper, the method is applied to earnings and dividend announcements, which have been documented to be information events. The authors study three groups of announcements: (a) joint announcements—i.e., earnings and dividend announcements that are made on the same day, (b) initial (first) announcements—earnings or dividend announcements that were not preceded by another announcement in the prior thirty days, and (c) following (second) announcements—those announcements that follow the first announcement by at least ten days but by no more than thirty days. The authors find a strong increase in information asymmetry only before the second announcements and virtually no increase before the joint and first announcements. This is consistent with the hypothesis that there is, on average, normal information asymmetry before announcements, but that the dealer will suspect a nonroutine announcement (with an attendant increase in information asymmetry) when the second announcement is separated from the first by more than ten days. Other possible explanations for the results are discussed, and suggestions for future research are outlined.     

Relation Between Predisclosure Information Asymmetry and Trading Volume Reaction Around Quarterly Earnings Announcements

This study investigates the effects of differences in predisclosure information asymmetry on trading volume reaction during quarterly earnings announcements. The analyses show that trading volume reaction to quarterly earnings announcements is positively related to the level of predisclosure information asymmetry and to the magnitude of the price reaction to the announcements. These results are consistent with Kim and Verrecchia's (1991a) theoretical trading volume proposition, and with Atiase and Bamber's (1994) tests of the proposition based on annual earnings announcements. This study also provides evidence on the relation of predisclosure information asymmetry and trading volume before and after quarterly earnings announcements.     

Venture Capitalists,Unquoted Equity Investment Appraisal and the Role of Accounting Information

This paper aims to add to the understanding of venture capitalists' investment decision-making behaviour by providing evidence relating to the general policies they adopt in their approaches to due diligence, valuation methods, benchmark rates of return and adjustments for risk. The evidence shows that in order to address potential adverse selection problems, venture capitalists use a wide range of accounting and non-accounting information and techniques relating to the specific factors concerning a particular investment. Unpublished accounting information and subjective information are important. Significant differences emerge in the approaches to valuation and use of accounting information for valuation purposes between types of venture capitalist, according both to their stage of investment focus and whether they were captive or independent.     

Information Asymmetry and Corporate Liquidity Management: Evidence from Real Estate Investment Trusts

We examine the impact of information asymmetry on a firm??s choice between cash and credit lines for corporate liquidity management using a panel data set from real estate investment trusts (REITs). Information asymmetry, as measured by analyst forecast error and dispersion, is negatively related to the use of lines of credit. Specifically, firms with more severe information asymmetry are less likely to have access to bank credit lines. Concurrently, more transparent firms are more likely to utilize bank credit lines as opposed to cash for liquidity management. The results are robust to alternative information asymmetry proxies and specifications. These findings suggest that information asymmetry plays an important role in corporate liquidity management.     

Institutional Shareholder Investment Horizons and Seasoned Equity Offerings

Firms with more short‐term institutional shareholders experience significantly more negative abnormal returns at the announcement of seasoned equity offerings. This effect is strong for primary offerings (only firms receive proceeds), but is not present for secondary offerings (firms do not receive any proceeds). Furthermore, a shorter institutional shareholder investment horizon predicts poorer postissue abnormal operating performance and the negative effect of a shorter shareholder horizon is mitigated by higher managerial ownership. My results are consistent with the argument that long‐term shareholders more carefully monitor managerial activities and prevent misuse of the cash flow provided by equity issues.

Public Predisclosure Information, Firm Size, Analyst Following, and Market Reactions to Earnings Announcements

Abstract:   This study examines the effects of public predisclosure information on market reactions to earnings announcements. We develop an empirical measure of public predisclosure information impounded in price prior to earnings announcements by cumulating abnormal returns on public news release dates during the quarter. Consistent with prior literature, we document a negative association between this measure and market reactions to subsequent earnings announcements. Moreover, we find that after controlling for this measure, firm size and analyst following are significantly positively associated with market reactions to earnings announcements. Contrary to prior empirical evidence, our results suggest that, after controlling for actual predisclosure information impounded in price, market reactions to earnings announcements are greater in magnitude for larger, more widely-followed firms than for smaller, less widely-followed firms.     

信息不对称、过度自信与股价变动

信息传导的非同步和投资者情绪变化是股票市场的两个典型特征,前者会引发投资者之间出现信息不对称问题,后者主要体现为投资者过度自信,两者共同作用影响股票价格变动。本文将信息不对称和投资者过度自信情绪置于同一个分析框架,建立两阶段动态序贯定价理论模型研究现实市场上信息传导过程中股价变动的内在机制。结果表明:(1)面临新信息的进入,投资者对股票收益预期的调整与均衡价格之间具有正相关关系;(2)面临有利消息时,过度自信投资者比例越大,股票的均衡价格越高,投资收益将越低;面临不利消息时则相反;(3)随着过度自信投资者比例以及过度自信程度升高,市场风险溢价将下降;(4)投资者群体在信息传导过程中出现分化,对股价变动形成异质信念,未获取信息和获取信息但未出现过度自信的投资者认为股价被高估,获取信息且出现过度自信的投资者认为价格被低估,促使更多的交易,引发市场成交量和股价变动;(5)过度自信投资者比例与过度自信程度提高均会对市场效率产生正向影响,而对市场深度具有负向效应。最后,基于理论结果对非对称性和持续性等典型的市场波动性特征进行解释。     

Earnings Predictability, Information Asymmetry, and Market Liquidity

We investigate the relation between earnings predictability, information asymmetry and the behavior of the adverse selection cost component of the bid-ask spread around quarterly earnings announcements for NASDAQ firms. While we find an increase in the adverse selection component of the bid-ask spread on the day of and the day prior to quarterly earnings announcements for firms with less predictable earnings, we find no evidence of such changes for firms with more predictable earnings. During a non-announcement period, we find that firms with relatively less predictable earnings have consistently higher total bid-ask spreads than firms with more predictable earnings. This finding suggests that firms with relatively less predictable earnings have a higher cost of equity capital than comparable firms with more predictable earning streams, ceteris paribus. Hence, earnings predictability may be a legitimate concern of managers who wish to minimize their cost of equity capital at least as it pertains to bid-ask spreads.     

高管交易行为、信息不对称与公司治理

基于沪深股市高管交易行为信息披露,在对高管卖出行为短期市场效应研究基础上,进一步研究高管买入、卖出行为的短期和长期市场效应及其产生根源.结果发现,无论从短期还是长期来看,高管买入行为有显著为正的市场效应,而卖出具有显著为负的市场效应,并且交易量越大、日内交易次数越多,市场效应越强烈.进一步结合公司治理理论发现,终极控股股东控制权与现金流权分离导致更强的买入市场效应,而法制环境抑制了买入市场效应.     

次贷危机、信息不对称和指数交易

次贷危机源于房价上涨停滞后的次贷及其衍生品市场的快速萎缩,信息不对称在危机爆发前风险累积阶段和危机后市场过度反应阶段都是关键因素.次贷及其衍生产品设计繁复且对房价系统性下跌高度敏感,次贷的衍生产品多在场外市场交易使得危机前相关信息未被充分披露.随着指数交易的陆续推出,如基于次债的ABX.HE指数和CME的房地产价格指数期货期权合约,使房价、次贷及其衍生产品的概括性信息得以揭示,基于信息不对称因素的恐慌加重了危机程度.综上,本文针对衍生品设计和市场的完善提出了建议.     

会计稳健性、信息不对称与股权融资成本

本文以沪深股市2006—2015年非金融行业上市公司为初始样本,结合我国的产权性质,考察了会计稳健性与股权融资成本的关系,并采用中介效应分析方法,探讨了会计稳健性对股权融资成本的可能影响路径。研究发现:第一,会计稳健性与股权融资成本负相关,信息不对称水平是会计稳健性影响股权融资成本的一个中介变量。第二,相对于国有企业,非国有企业会计稳健性对股权融资成本的降低作用更加显著。
