Recent studies show firms suffering drug recalls experience security losses many times larger than any reasonable measure of their direct cost. We discover that the implied standard deviation of stock returns from the Black-Scholes option pricing model significantly increases after a drug recall. The implied standard deviation provides a good proxy for the stock's ex ante beta. The higher systematic risk after a product recall must raise the discount rate used by investors. After a recall, stock prices are reduced in line with the lower expected future earnings and are further reduced because of a higher discount rate.  相似文献

This paper examines the information aggregation role of options when agents possess diverse information about possible asset returns. We construct two identical experimental markets: one with and one without options. We find that options speed the information aggregation process. Asset markets that have parallel option markets aggregate traders' diverse information faster than markets where options trading is not available. Implied ranges were calculated from asset and option prices and compared to the actual ranges. These comparisons suggest that options may provide a means for agents to coordinate beliefs about asset values.  相似文献

This paper examines the impact of user-generated feedback on price at a price comparison site or shopbot. It employs a modified hedonic price function to explore the use made by current potential consumers of the experience of past actual consumers in evaluating quality attributes that were not observable when the product was initially launched on to the market. Using a database of daily observations on 211 digital cameras traded on NexTag.com, we find that the product’s star rating, reflecting all the available individual assessments of the product, has a significant negative impact on the discount on the manufacturer’s recommended selling price at which the product is offered.  相似文献

The demand for Toll Free Numbers (TFNs) languished from 2000 to 2008; however recent growth in demand caused the FCC to open a new toll-free code (855) with the possibility of new code openings in the next three years. The analysis here indicates the demand for TFNs is highly inelastic (the coefficient for own price elasticity for TFNs is approximately −0.04). This has implications for concerns regarding future exhaust of toll-free codes and the price structure for recovery of SMS/800's costs. This article considers the effects of the limited property rights for TFN, and welfare implications of gray markets for vanity TFNs. The FCC's allocation mechanism for new 855 codes is considered and whether other allocation mechanisms, such as auctions, could be welfare superior.  相似文献

The internationalisation of the firm is a highly dynamic process, in which periods of investment and expansion intermingle with periods of divestment and retrenchment. Academic research to date has focused on identifying the reasons for and the processes of divestment. Empirical studies either evidence generic pressures or provide case studies of specific incidents. There few longitudinal studies of international divestment, consequently the dynamic interactions between host market, home market and firm level factors, and how the institutional context changes over time is underplayed. This paper seeks to rectify this gap in our understanding.We explore the rationale and evolving dynamics of European grocery retail divestment in East Asia over a thirty year period. Taking an inductive approach and drawing on analysis of contemporary narratives drawn from company documentation, trade journals, newsfeeds and market reports, three phases can be identified characterised by specific factors and combinations of factors which intersect to provide the key pressures and stimuli for divestment. We conclude that at different time periods, different internal and external contextual influences manifest themselves through different priorities within the firm’s strategy – marked by a switch from local (host) market, to regional, to global firm-centric considerations. Longitudinal analyses allow a greater recognition of this dynamic interplay of factors, and the changes in these relationships, and provides a more nuanced understanding of the international divestment process.  相似文献

The intrinsic motivation of a firm’s management for engaging in prosocial behavior is an important determinant of a firm’s social conduct. I provide the first model in which firms run by morally motivated managers engage in corporate social responsibility (CSR) in a competitive setting. Moral management crowds out a competitor’s strategic CSR, increasing profitability and leading shareholders to strategically delegate moral managers, although necessary for socially optimal CSR is that shareholders be morally motivated as well. Shareholders appoint managers that engage in a socially excessive amount of CSR, counter to existing literature, whenever product‐market competition is sufficiently intense.  相似文献

This paper examines the value of seller reputation for e‐retailers trading via a price comparison site (PCS). E‐markets are widely held to accommodate sellers of differing service quality, including some who behave opportunistically. The paper uses a sample of offers on up to 295 digital cameras traded on a leading PCS, over a 134‐day period to estimate reputation's price impact. User‐generated reputation measures have a significant impact in the expected direction. However, their magnitude is small compared with variables capturing economy‐wide reputation. The strength of the reputation signal increased non‐monotonically with the number of reviews on which it was based. Copyright © 2015 John Wiley & Sons, Ltd.  相似文献

Conventional wisdom holds that the performance of investment managers should be measured against some broad market index such as the S&P 500. The broad market averages provide a useful benchmark because they are assumed to be beyond the influence of investment managers and provide a way of capturing what financial economists call “systematic risk,” which is the part of total risk that cannot be avoided through portfolio diversification. But one clear limitation of such an approach to performance evaluation is that by focusing on risks and rewards at the portfolio level only, it fails to consider risks and rewards at a systemic level, where the performance of all portfolios is increasingly likely to be affected. The author begins by making the case that the performance evaluation and collective decision‐making of investment managers could have the effect of increasing the level of systematic risk in both the markets and the real economy. Then, after suggesting that the strength or weakness of environmental, social, and governance (ESG) frameworks can have substantial effects on overall market returns, he discusses a number of efforts currently underway to integrate ESG factors into portfolio‐level decision‐making. The author closes by urging asset owners to take the following three steps to help bridge the gap between investment decision‐making and ESG consequences: (1) acknowledge the connection between investment decision‐making and systems‐level risks and rewards; (2) determine which systemic frameworks are most appropriate and useful for their purposes; and (3) implement investment practices that allow them to manage systemic‐level risks and rewards while simultaneously achieving competitive financial returns in their portfolios. With the help of new measurement and management tools, asset owners can strengthen systemic frameworks, communicate the importance of ESG performance to their investees and investors, and align their efforts with those of governmental and non‐governmental organizations to limit systemic risk.  相似文献

Despite considerable empirical evidence reporting a negative relationship between net share issuance and subsequent returns, it remains unresolved whether this anomaly is explained by risk or investor irrationality. This study examines the net share issuance anomaly using seasoned equity offerings before and after the introduction of an imputation tax system. We report robust evidence of a negative relationship between net share issuance and returns post‐imputation, but no relationship pre‐imputation. Our results provide evidence to support the international pervasiveness of the net share issuance anomaly, but more importantly suggest that this anomaly may be explained by risk.  相似文献
