Semistatic hedging and pricing American floating strike lookback options

We price an American floating strike lookback option under the Black–Scholes model with a hypothetic static hedging portfolio (HSHP) composed of nontradable European options. Our approach is more efficient than the tree methods because recalculating the option prices is much quicker. Applying put–call duality to an HSHP yields a tradable semistatic hedging portfolio (SSHP). Numerical results indicate that an SSHP has better hedging performance than a delta-hedged portfolio. Finally, we investigate the model risk for SSHP under a stochastic volatility assumption and find that the model risk is related to the correlation between asset price and volatility.     

DO FIRMS SEEK A TARGET BOARD STRUCTURE? EVIDENCE FROM THE POST‐SOX PERIOD

We investigate whether firms restructure board composition to align with changes in their contracting environment. Board size and independence increase with firm complexity, consistent with theoretical predictions. However, the hypothesized negative relation between board independence and information costs is evident only for firms completing acquisitions. Furthermore, board independence increases to offset increases in CEO power in a sample of firms making acquisitions, but decreases when CEO power increases in a large cross‐section of firms. We conclude that after the Sarbanes–Oxley Act of 2002, firms face constraints adjusting to target board structure, but these constraints can be mitigated by a shock to the contracting environment via acquisition.     

以“三个代表”重要思想为指导建设社会主义政治文明

江泽民同志在十六大报告申提出发展社会主义民主政治,建设社会主义政治文明,这是我们党根据历史潮流和时代发展的要求提出来的一个新的理论概念。从我国国情出发建设社会主义政治文明最根本的就是坚持党的领导,人民当家作主和依法治国的有机统一。社会主义政治文明与"三个代表"重要思想是不可分割的有机整体。在当前国际国内形势下,更迫切地要求我们要以"三个代表"重要思想为指导,加强社会主义政治文明建设。

财政分权与义务教育财政管理体制问题探析

我国是成功实施财政分权化的国家之一。作为公共财政框架部分之一的义务教育也实行了分权化管理,义务教育办学的责任主要地落在了县、乡两级地方政府身上。而我国庞大的义务教育事业由县、乡甚至村脆弱的财力来承担,可谓“杯水车薪”：一些农村地区和贫困山区学龄儿童无学可上,无书可读等现象屡见不鲜。可见过度分权化的义务教育财政管理体制是制约当今中国义务教育发展的症结所在。     

Earnings management by firms announcing earnings after SEC filing

This study examines motivation and stock market reactions of firms announcing earnings in the Wall Street Journal (WSJ) after filing with the Security Exchange Commission (SEC). Most firms announce earnings in the WSJ before SEC filing. Firms that reverse this sequence are voluntarily delaying public earnings announcements. The authors find that these firms are not only poor financial performers but also engage in earnings managements. They are delaying their WSJ announcements to postpone announcing bad news. The authors find significant stock price reactions to both the SEC filing and the WSJ announcement. The price reaction to earnings is incomplete at the SEC filings. The market continues reacting to firms' subsequent WSJ announcements as if the SEC filing fails to communicate earnings information to some investors.     

上市公司资产减值方向信息含量研究——来自沪深两市2003年的经验证据

我国新颁布的《企业会计准则第8号——资产减值》规定,存货等已确认的资产减值不得转回。针对新准则对资产减值单向计提的规定,本文从资产减值准备计提方向研究上市公司资产减值的信息含量,发现资产减值的计提方向存在信号显示作用。这表明资产减值准备方向传递了公司未来前景的信息,全面取缔资产减值准备的转回将减少资产减值的部分信息含量。

契约“诚信”问题与解“困”——法和经济学的视角

目前我国存在普遍的诚信危机,契约方面是一重灾区,究其原因,在于“失信”机会主义行为的效益性,及“失信”违法行为成本的低廉性。本文试图从经济学和法学相结合和学科角度,以契约方面的“诚信危机”为例,从经济学和法学的角度探讨一种“去效益”和“失信”违法成本加大,并倡导法律建立“信用权”等综合性的策略。从而克服由诚信危机带来的契约主体和“囚徒困境”和社会经济秩序的混乱和低效率运作。     

Inoculating consumers against deception: The influence of framing and executional style

This study examines conditions affecting consumer susceptibility to advertising deception and educational efforts designed to inoculate consumers against it. Results show that consumers are best able to detect deception when their frame of reference (cognitive or affective) is incongruent with the advertisement's executional style (attribute or emotional). Attempts to inoculate consumers against deception by providing factual brand comparisons have their strongest effect among consumers with an affective frame of reference and for emotionally charged ads.

Die Immunisierung von Konsumenten gegen werbliche Irreführung: Der Einflu der persönlichen Informationsausrichtung und des werblichen Argumentationsstils

Zusammenfassung Die Studie befa\t sich mit den Bedingungen werblicher Irreführung von Konsumenten und mit den Bemühungen der Verbrauchererziehung, Konsumenten durch vergleichende Warentestergebnisse gegen solche Irreführung zu immunisieren. Ihre Ergebnisse zeigen, da\ Konsumenten werbliche Irreführung am ehesten dann durchschauen, wenn ihre persönliche Informationsausrichtung (kognitiv oder affektiv) nicht mit dem werblichen Argumentationsstil (informativ oder emotional) übereinstimmt. Versuche, Konsumenten mit Hilfe vergleichender Warentest-Informationen gegen werbliche TÄuschung zu immunisieren, sind am wirkungsvollsten bei Konsumenten mit affektiver Informationsausrichtung und bei emotionshaltiger Werbung.
