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

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 compares the output and revenue effects in the rate-of-return regulated monopoly model. Both the ad valorem and the unit tax generally decrease the use of capital, and as such, reduce the output and raise the price. In addition, it is shown that Suits and Musgrave's conclusion of higher revenue of an ad valorem tax at a given output can apply to a regulated monopolist if the marginal product of labor under the ad valorem tax is greater than or equal to that under the unit tax. Similarly, their second conclusion, that for a given tax revenue an ad valorem tax has a larger output than a unit tax rate before the revenue-maximizing tax rate, can also apply to the regulated monopolist. 相似文献

Hedonic models and air pollution: Twenty-five years and counting 总被引:2,自引:1,他引:2
This paper reports a meta analysis of how effectively hedonic property models have detected the influence of air pollution on housing prices. Probit estimates are reported describing how data, model specification, and local property market conditions in cities represented in thirty-seven studies influence the ability of hedonic models to uncover negative, statistically significant relationships between housing prices and air pollution measures.Partial support for this research was provided by the Russell Sage Foundation. Thanks are due David Cordray, Heidi Hartman, and Larry Hedges of the Foundation's Meta-Analysis Panel for constructive comments, to Ray Palmquist for suggestions and assistance in assembling the results from his studies, to Rick Freeman and Tom Tietenberg and two anonymous referees for comments on the research, and to Barbara Scott for constructive editing of earlier drafts of this paper. 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

This paper examines the volume distribution of option trade prices that occurs when the underlying stock price remains constant. The width of these option trade price bands provides direct evidence on the law of one price and the redundancy of options assumed in many option models. We find that index option bands are narrower than equity option bands. Furthermore, for both equity and index options, puts have narrower bandwidths than calls. In general, option price bandwidth is narrow and can be explained by the minimum price movement allowed by the Chicago Board Options Exchanges (CBOE). This supports the single price law and the redundancy assumption. The existence of bid/ask quotes on the option does not materially affect the above results although it does alter the frequency of multiple option trade prices for a given underlying stock price. We note that over 53% of option trading volume occurs without bid/ask quotes on the CBOE compared to less than 15% a decade ago. Our results suggest that the effective bid/ask spread on options is probably no larger than the minimum price movements allowed by the CBOE. Furthermore, the need for the liquidity services of market makers may be declining if the decline in quoting activity stems from cross trading (i.e. trades not involving market makers). 相似文献

Innovation capital are typically expensed and/or unrecognized as assets under current generally accepted accounting principles.
This results in accounting-related information asymmetry. This paper examines the association of innovation capital (as measured
here by the proxies of R&D expenditures and granted patents) and initial public offerings (IPO) anomalies. These anomalies
include initial IPO underpricing, duration of honeymoon (a distinct feature of the Taiwanese IPO environment), and long-term
performance. The theoretical model underlying this research is a signaling model. The results indicate that more innovative
firms are more likely to be underpriced, and have longer honeymoon periods than less innovative firms. Further, the more innovative
firms have positive and growing long-term market-adjusted returns. This stands in contrast to the declining long-term stock
performance of initial public offering firms that is evidenced in the literature. We conclude that pre-IPO research and development
expenditures disclosed in the IPO prospectus, official monthly reports of newly developed patents released to the public,
and the frequency of patent citations significantly signal both underpricing and future market performance of IPO firms in
Taiwan. 相似文献
