市场反应、生存模型与信息披露

本文应用生存模型对上市公司年报信息披露后股票市场价格反应时间进行研究，选择沪深两市在2004年710家样本公司年报信息披露后的股票价格作为研究对象，使用生存模型研究股价的变动方向和价格沿同一方向持续变动的时间。研究结果表明，上市公司的业绩变量、行业因素、市场交易状况和审计意见类型对市场反应时间有明显的影响，投资者可以选取关键指标来预测市场反应。

高管持股、择时披露与市场反应

基于2001至2008年间A股公司业绩预告的样本,本文研究了高管持股对择时信息披露策略的影响,以及市场对择时披露信息的反应。研究发现,A股公司在业绩预告时存在择时披露的行为:好消息①更倾向于在交易日披露,坏消息更倾向于在休息日披露。高管持股比例会显著影响择时披露策略:高管持股比例越高的公司,进行择时披露的可能性也越高。从市场反应角度看,休息日披露的坏消息与交易日披露的坏消息没有显著差异,休息日披露的好消息反而会产生更加显著的正面市场反应。本文的研究意味着,高管持股比例会显著提高上市公司进行择时信息披露的可能性,但是市场在一定程度上能够识别择时披露策略,本文的研究结果支持了"信息消化"假说。     

信息披露质量与资本市场估值偏误

资本市场估值偏误阻碍了证券市场的健康发展。信息不对称是导致上市公司市场价值长期偏离内在价值的根本原因,因此信息披露行为对资本市场估值偏误的影响值得研究。采用剩余收益模型(RIM)估计上市公司内在价值,在此基础上构建度量资本市场估值偏误的代理变量,并采用KV度量法从总体上考察上市公司信息披露质量,本文检验了信息披露行为对资本市场估值偏误的影响。本文研究发现上市公司市场价值对其内在价值的偏离程度与信息披露质量显著负相关;进一步的研究表明,信息披露修正资本市场估值偏误的主要途径,是降低市值高估公司的市场价值泡沫。

Practice versus Prescription in the Disclosure and Recognition of Derivatives

The contentious issue of the recognition and measurement of derivative instruments is again high on the Australian standard-setting agenda, following pronouncements by the International Accounting Standards Committee (USC) and Financial Accounting Standards Board (FASB). This study investigates firms' disclosure of derivative accounting policies and measurement practices pursuant to the introduction of AASB 1033. A lack of clarity and completeness in the disclosures suggests that supplementary requirements are necessary. A preference for using hedge accounting is also apparent. Should an Australian standard disallow or impose conditions on hedge accounting, fims will need to alter their current accounting practices and risk management strategies and they will probably reassess their use of derivatives.

Disclosure Versus Recognition: Inferences from Subsequent Events

Standard setters explicitly state that disclosure should not substitute for recognition in financial reports. Consistent with this directive, prior research shows that investors find recognized values more pertinent than disclosed values. However, it remains unclear whether reporting items are recognized because they are more relevant for investing decisions, or whether requiring recognition itself prompts differing behavior on the part of firms and investors. Using the setting of subsequent events, I identify the differential effect of requiring disclosure versus recognition in a setting where the accounting treatment of an item is exogenously determined. For comparable events, I find a stronger initial market response for firms required to recognize relative to firms that must disclose, although the large magnitude of the identified effect calls into question whether this difference can be attributed to accounting treatments alone. In examining various reasons for the stronger market response to recognized values, I fail to find support for the hypothesis that this difference is due to differential reliability of disclosed and recognized values. I do find some evidence that investors underreact to disclosed events, consistent with investors incurring higher processing costs when using disclosed information.     

Corporate Disclosure,Market Valuation,and Firm Performance

In this paper, I study the relationship between the Association for Investment Management and Research disclosure rankings and several corporate performance measures. I find a positive relationship between these rankings and stock returns. Furthermore, disclosure rankings are highly correlated with firm value. Specifically, Qs of firms ranked at the top of disclosure rankings are 35% higher than those of firms ranked at the bottom. I also find positive associations between disclosure rankings and future net profit margins, sales growth, and research and development intensity. Finally, I document a positive correlation between changes in disclosure rankings and future earnings surprises.     

Trade Disclosure,Information Learning and Securities Market Performance

In this paper we examine the effect of information disclosure on securities market performance when liquidity traders are able to acquire information about inside trading. We show that the bid-ask spread increases with the liquidity trader's learning efficiency, which is greater when trade information is disclosed. The bid-ask spread is always higher when trade information is not disclosed. However, the discrepancy between the bid-ask spreads with and without information disclosure narrows when the learning efficiency increases. We also show that the gains of the informed traders in a market without trade information disclosure are reduced in the presence of the liquidity trader's learning. Nevertheless, liquidity traders do not necessarily benefit from increased transparency. In particular, liquidity traders may face higher trading costs.

Keynesian Beauty Contest, Accounting Disclosure, and Market Efficiency

This paper examines the market efficiency consequences of accounting disclosure in the context of stock markets as a Keynesian beauty contest, an influential metaphor originally proposed by Keynes [1936] and recently formalized by Allen, Morris, and Shin [2006]. In such markets, public information plays an additional commonality role, biasing stock prices away from the consensus fundamental value toward public information. Despite this bias, I demonstrate that provisions of public information always drive stock prices closer to the fundamental value. Hence, as a main source of public information, accounting disclosure enhances market efficiency, and transparency should not be compromised on grounds of the Keynesian-beauty-contest effect.     

信息披露、公司规模与债券市场发展困境

我国债券市场面临着缺乏规模效益、发展不均衡等发展困境。通过实证结果表明：我国债券市场准入的门槛限制与公司信息披露质量不高是造成其发展困境的主要原因;在公司规模一定时,信息披露质量越高,债券融资比例越高;信息披露质量一定时,公司规模越小,债券融资比例越高。因此,降低债券市场准入的门槛限制,提高公司信息披露质量是促使我国债券市场走出发展困境的两个关键措施。     

对政府与市场关系的再认识

关于政府与市场关系的争论,一直与近代人类社会的发展紧密相随,直到今天也没有停止。相反,倒是因为一次次的经济危机而不断掀起高潮。在争论中形成的一点共识就是:不论政府还是市场,都是推动人类社会发展不可或缺的手段之一。后来的争论,基本上是围绕着政府或市场的此进彼退而进行。本文在对政府与市场关系进行再认识的基础上认为:在经济危机的背景下,我们在对二者关系认识的不断深化过程中,一方面要注意把争论的焦点从二者的彼此替代上转移出来,二是要注意除此以外,是否还有其他可补充的途径,并据此提出政府-市场-社会三者并行的发展模式。

Voluntary Disclosure with Informed Trading in the IPO Market

We examine voluntary disclosure and capital investment by an informed manager in an initial public offering (IPO) in the presence of informed and uninformed investors. We find that in equilibrium, disclosure is more forthcoming—and investment efficiency is lower—when a greater fraction of the investment community is already informed. Moreover, managers disclose more information when the likelihood of an information event is higher, more equity is issued, or the cost of information acquisition is lower. Investment efficiency and the expected level of underpricing are non‐monotonic in the likelihood that the manager is privately informed.
