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. 相似文献

Disclosure standards mandate the quantitative disclosure of hedging‐instrument‐related risks but not the disclosure of hedged‐item‐related risks. We examine how a match (mismatch) in formats, caused by making quantitative (qualitative) hedged item disclosures alongside quantitative hedging instrument disclosures, affects investors' integration of information from these two related disclosures. Our first experiment varies the hedged item disclosure format (quantitative or qualitative) and the portion of risk hedged (small or large). We find that when disclosure formats are mismatched, the less comparable nature of the two disclosures caused investors to neglect the offsetting relationship when assessing net risks. As a result, risk and investment judgments were influenced by the more prominent quantitative hedging instrument disclosures. Our second experiment finds that the use of a qualitative debiaser that clarifies the relationship between the two disclosures led to the integration of information and mitigated this effect. 相似文献

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. 相似文献

This paper uses the Russian Longitudinal Monitoring Survey (RLMS) to analyse the dynamics of moonlighting by the working‐age population. We find that moonlighting is transitory and that a desire to switch jobs expressed in the past is positively related to moonlighting in the present and to actual job changes in the future. We also find that workers who moonlighted as self‐employed in the past represent 26.5 percent of the new self‐employed. These results suggest that moonlighting in Russia can be seen as an effective incubator for setting up new self‐employed businesses, thereby providing long‐term benefits for the economy. 相似文献

We examine investment behavior among exchange-listed Korean manufacturing firms before and after the 1997 financial crisis using firm-level panel data. Starting with the standard Q-theory of investment, we augment it by allowing for a sales accelerator and the possibility of cash constraints, categorizing firms based on their age, size and affiliation to an industrial conglomerate (i.e., chaebol). We find that Tobin’s Q is a robust determinant of investment in a pooled sample for 1992–2001, but that it became more important for small firms and less important for chaebol-affiliated firms after the crisis. Investment by chaebol firms also became more sensitive to the availability of internal cash balances after the crisis. We interpret this as reflecting a shift in the Korean economy to a stronger market orientation after the crisis and to a business climate in which the quality of potential projects became more important relative to capital market imperfections in determining the destination of investment funds. 相似文献

A multivariate model of the process by which managers decide to release public forecasts of their firms' earnings is developed, based on factors that are hypothesized to affect the demand for and the willingness to supply such forecasts. We test the model on data from a comprehensive sample of earnings forecasts, and find support for our hypotheses about the likely joint influence of those factors. Larger firm size, greater leverage, higher and more stable earnings rates and less rapid growth rates are found to be associated with an increased propensity for management to provide earnings forecasts for their firms. 相似文献

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. 相似文献

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.

The Informational Role of Stock and Option Volume 总被引:8,自引:0,他引:8
This article analyzes the intraday interdependence of orderflows and price movements for actively traded NYSE stocks andtheir Chicago Board Options Exchange (CBOE)-traded options.Stock net trade volume (buyer-initiated volume minus seller-initiatedvolume) has strong predictive ability for stock and option quoterevisions, but option net trade volume has no incremental predictiveability. This suggests that informed investors initiate tradesin the stock market but not in the option market. On the otherhand, both stock and option quote revisions have predictiveability for each other. Thus, while information in the stockmarket is contained in both quote revisions and trades, informationin the option market is contained only in quote revisions. 相似文献

This paper examines liquidity and quote clustering on the NYSE and Nasdaq using data after the two market reforms—the 1997 order–handling rule and minimum tick size changes. We find that Nasdaq–listed stocks exhibit wider spreads and smaller depths than NYSE–listed stocks and stocks with higher proportions of even–eighth and even–sixteenth quotes have wider quoted, effective, and realized spreads on both the NYSE and Nasdaq. This result differs from the findings by Bessembinder (1999, p. 404) that "trade execution costs on Nasdaq in late 1997 are no longer significantly explained by a tendency for liquidity providers to avoid odd–eighth quotations," and "odd–sixteenth avoidance has little relevance for explaining post–reform Nasdaq trading costs." 相似文献
