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.     

从博弈论看保险市场信息不对称的本质及规范举措

博弈论是研究信息不对称问题的一种有效方法。保险业作为信息不对称最为集中的行业，保险人与被保险人之间存在着严重的信息不对称，特别是被保险人的逆向选择、道德风险和保险人的违规操作等现象普遍存在，长期困扰着保险界。

基于绿色成本信息不对称,运用博弈方法,构建二级绿色订单农业供应链,考量订单农业合约设计.结果表明:信息不对称下,采用批发价合同,公司利润可能受损,当公司高估绿色成本时,农户获利;采用收益分享合同,公司利润可能受损,但有利农户.无论信息是否对称,当农户的保留收益、绿色努力成本系数或产出不确定性较小时,公司宜选择收益分享合同;反之,宜选择批发价合同.与批发价合同相比,菜单合同可以降低信息不对称性和供应链的"双边际"效应,激励农户增加绿色投入,促进优质绿色农产品供给和各主体增收.     

Universal Banking,Conflicts of Interest and Firm Growth

This paper studies the relationship between universal banking and firm performance. With 40 developing and developed countries, I find that the overall effect of universal banking on firm growth is negative. This suggests that the negative effect of conflicts of interest dominates the positive effect of economies of scale and scope in universal banking. However, in countries with stronger protection of creditors’ rights and higher information efficiency, conflicts of interest are less likely and the negative relationship between universal banking and firm growth is significantly weaker.

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 Bidders' Gains

Abstract:  Undervalued firms with high information asymmetry may announce takeover bids to attract the attention of investors with a view to increasing the share price through revaluation. Announcement period returns to such bidders should include both revaluation and synergy gains although the revaluation gains should be confined to early bids and decline with the number of bids announced within a reasonable period. Our results offer strong support to these predictions. Undervalued firms with high pre-bid information asymmetry gain the most from early bids and the gains decline with the number of bids announced. These findings are robust to methods of payment, relative size of deals, target status, relatedness of businesses, domicile of target, M&A activities and alternative measures of information asymmetry, and confirm that gains from early bids include revaluation as well as synergy gains, especially in the cases of undervalued firms with high information asymmetry.     

Effects of Deposit Insurance Reform on Moral Hazard in US Banking

In cross sections of US banks before the deposit-insurance system was reformed in the early 1990s, bank risk-taking was positively associated with bank size and negatively associated with the value of bank charters and bank capital. These empirical associations have an easy theoretical interpretation. Bank size is positively related, while charter value and capital are negatively related, to the moral hazard associated with flat insurance premiums and other aspects of a laxly administered system. Hence the observed associations of risk-taking with size, charter value, and capital reflected the expected positive relation between moral hazard and risk-taking. We test the hypothesis that the three associations became weaker after reform. In the case of unsystematic risk, we find no evidence of significant changes for any of the three. In the case of systematic risk, we find that risk-taking associated with lower charter values and larger size is indeed significantly weaker after reform. Risk-taking associated with capital ratios is also weaker after reform, though not significantly so. Since systematic risk is undoubtedly the more appropriate measure, reform seems to have reduced moral hazard.     

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.     

Information Asymmetry and Corporate Cash Holdings

This study analyzes the effect of information asymmetry on corporate cash holdings. Using various measures of information asymmetry, this study shows that companies that operate in environments with higher information asymmetry have smaller cash holdings. This study continues to find a negative relationship between information asymmetry and corporate cash holdings from a battery of sensitivity analyses, including the tests using different regression methods and the difference‐in‐difference tests employing brokerage‐firm merger and closure events. On the whole, the results support the monitoring cost hypothesis of cash holdings over the investment opportunities hypothesis.     

交叉上市、信息不对称与风险特征

本文以"A+H"交叉上市公司价格差异为研究对象,对A股、H股股票价格之间差异及其变化进行研究。根据对36家A+H股上市公司近期9个月溢价水平的分析发现,信息不对称理论能够解释AH股溢价扩大的现象,投资者与公司之间信息不对称问题得到缓解的趋势不明显,反而有所强化;国有股特征导致AH溢价缩小,海外投资者对国有股份的认同度提升;流动性理论、不同风险偏好理论不能解释AH溢价变化,数据分析支持信息不对称理论、风险特征理论和需求理论。

信息不对称与小额信贷创新

面向落后群体或遭受信贷歧视的经济主体开展的“小额信贷”(Microcredit,或称“微贷”),是对信贷市场失灵的一种补充,然而其本身也同样面临着信息不对称问题.从导致金融市场失灵最核心的因素即信息不对称出发,讨论在过去几十年间,小额贷款技术创新在修正这一市场失灵上所取得的进展,并对其中涉及的主流小额贷款技术进行评价,以期对我国的小额信贷产业发展起到借鉴作用.     

Target Information Asymmetry and Acquisition Price

This study investigates the effects of target information asymmetry in a takeover transaction. We find that a target with more information asymmetry receives a larger bid premium from the acquirer. We examine the response of the acquirer's investors to the bid to clarify whether the larger bid premium is an overpayment by the acquirer. We observe that the acquirer's investors respond more positively to the acquisition of an opaque target, indicating that the market recognizes the acquirer's valuation of the opaque target and agrees with the offer price. Our results indicate that corporate takeovers help to resolve asymmetric information in the capital market.     

Information Asymmetry and Earnings Management: Some Evidence

This paper conducts an empirical investigation of the relationship between information asymmetry and earnings management predicted by Dye (1988) and Trueman and Titman (1988). When information asymmetry is high, stakeholders do not have sufficient resources, incentives, or access to relevant information to monitor manager's actions, which gives rise to the practice of earnings management (Schipper, 1989; Warfield et al., 1995). Empirical results suggest a systematic relationship between the magnitude of information asymmetry and the level of earnings management in two different settings.     

Banking and Capital Market Activity in Dublin: Recent Developments and Future Prospects under the Euro

The introduction of Europe's single currency will have an immediate effect on the financial sectors of participating economies. While research in this area has focused on the broad implications for Europe's banking structure, this has been at the neglect of the smaller European financial centres which, while peripheral, make important contributions to their domestic economies. As a representative study, this paper examines how the recent developments in Ireland's financial sector will be affected by the introduction of the euro. It focuses on the probable contraction of Dublin's financial markets and assesses the threat of foreign acquisition facing its main domestic clearing banks.     

非对称信息理论与农村信贷市场——兼谈泰国BAAC的经验

从非对称信息理论出发，联系泰国农业合作银行（BAAC）的经营实际，笔者认为非对称信息引起的逆向选择和道德风险，是阻碍正规金融机构在农村开展金融业务的重要原因。解除金融抑制，实现农村利率自由化并不能完全解决农村正规金融弱化的问题，政府介入农村金融市场应该重点采取制度创新方式，帮助解决农村信息不对称问题，激励正规金融部门为农村提供金融服务。     

The Impact of Earnings Guidance Cessation on Information Asymmetry

This paper studies the impact of quarterly earnings guidance cessation on information asymmetry using a large sample of firms during the years 2002–11. After earnings guidance cessation, information asymmetry may increase because less information is provided to the market. Alternatively, information asymmetry may decrease if managers have less pressure to manage reported earnings to meet guidance numbers. Our study shows guidance cessation significantly reduces information asymmetry compared to matched non‐guiders and guidance maintainers. We also find that firms engage in less earnings management after guidance cessation, especially for firms that had provided guidance on a persistent basis.     

资本市场会计信息披露暨治理问题研究--基于上市公司会计信息披露不对称的视角

上市公司会计信息生产和披露质量直接影响了资本市场的稳定健康发展。资本市场会计信息生产和披露存在着一定的供求机理,直接影响了会计信息生产和披露的质量。由于管理主体上的虚化、内控弱化和治理结构上的偏差、会计信息系统的集成和共享性弱以及从业人员素质上的差异,使得上市公司会计信息披露存在着不充分性、非主动性、虚假性和滞后性问题,由此增加了资本市场信息不对称和风险发生的可能。因此,严厉打击资本市场会计信息造假,规范资本市场会计信息披露,需要进一步完善资本市场会计信息披露制度,创新和完善新技术背景下会计准则和会计制度,加强对现有上市公司会计信息生产和会计信息披露标准的制定和使用,提升上市公司会计信息生产和会计信息披露独立审计监督的标准化和规范化水平,加强上市公司会计信息生产和披露监督标准化体系建设。     

The Role of Transfer Price for Coordination and Control within a Firm

This paper explores the role of transfer prices as coordinating mechanisms within a firm. Three cases (full information; pure adverse selection; adverse selection and moral hazard) are analyzed and compared to show how quantity and effort are affected as assumptions on observability are progrssively relaxed. The analysis of the second case, having two observable variables, identifies the necessary and sufficient condition under which the local approach can be applied. The third case is reinterpreted as transfer prices in a direct delegation setting. The main results are: First, the optimal transfer price is standard average cost plus. Second, it is not necessarily decreasing in quantity unlike the downward sloping demand function.     

信息传递成本和预测能力不足对信贷契约的影响

信息传递成本和预测能力不足是影响信贷融资交易成本的主要因素。二者直接影响信贷融资具体方式的选择和融资过程的治理。治理这些问题的机制通常在利好情况下能够约束借款人恪守诚信,但是在利空情况下会导致低效率。能够缓解信息不对称和契约不完全问题的其他方式包括签订自我履行的信贷契约、构建关系性融资、提高契约法规的执法力度、营造诚信的商业环境和规范企业财务信息披露。
