We examine the spillover wealth effects of the Orange County, California bankruptcy announcement in December 1994 on municipal bonds, municipal bond funds, and bank stocks. This bankruptcy is prominent because of unprecedented losses and because it was caused by a highly leveraged derivatives strategy rather than a shortage of tax revenues and excess spending. We find contagion in the bond market with significantly negative abnormal returns for municipal bond funds without direct exposure to Orange County and for non‐Orange County municipal bonds. In addition, our findings suggest the contagion spills over to the common stocks of investment and commercial banks that deal in or use derivatives; however, the equities of banks unexposed to derivatives are not affected.  相似文献

Monitoring the mean and the variance of a stationary process   总被引:3,自引:0,他引:3  
We deal with the problem of how deviations in the mean or the variance of a time series can be detected. Several simultaneous control charts are introduced which are based on EWMA (exponentially weighted moving average) statistics for the mean and the empirical variance. The combined X − S2 EWMA chart is extended to time series. Further simultaneous charts are considered. The comparision of these schemes shows that the residual attempt must be favored if a variance change is present.  相似文献

In some of their papers published in the 1950s, Herbert Simonand Sidney Siegel responded to the so-called mixed strategyanomaly in ways which deserve more attention. They producednot only (i) immediate defences of the economic theory of theirown time, but also (ii) ideas and solutions that have laterturned out to be significant contributions to the developmentof the economic theory of choice and decision-making and theseparation of experimental economics from experimental psychology.These observations suggest that economics can be more responsiveto empirical anomalies than has been assumed. Furthermore, knowledgeof the desirable responsiveness to anomalies can provide meansof avoiding the non-desirable immunity to anomalies.  相似文献

ABSTRACT

This study examined the relationship between German tourists’ trust perceptions and their intention to book a sustainable hotel, pioneering a new quantitative approach to sustainable tourism marketing. Data came from 300 respondents who participated in an online survey. Respondents were given a digital brochure to read containing information about a “fictitious” three-star beach hotel in Portugal, before completing a questionnaire that measured inter alia their intention to book this sustainable hotel. Both individual “general trust” (perception of others’ trustworthiness) and “specific trust” towards the fictitious hotel in the brochure were measured. The survey also evaluated respondents’ perceptions about the usefulness of the information in the brochure. Multiple regression analysis of the data indicated that general trust, trusting the hotel and perceived usefulness of the brochure were positively and significantly related to booking intentions. An interaction between general trust and perceived usefulness was also observed. This means that the higher the perception rate about the brochure's usefulness, the higher general trust was for booking intentions and vice versa. The practical implications of the results suggest that tourists could be motivated to book a hotel if its sustainability attributes and amenities were communicated in a trust inspiring way in marketing material.  相似文献

Research summary: This article explores the relationship between corporate social irresponsibility (CSI) and financial risk. We posit that media coverage of CSI generates risk by providing conditions that increase the potential for stakeholder sanctions. Through analyzing an international panel of 539 firms during 2008–2013, we find that firms receiving higher CSI coverage face higher financial risk. We show that the reach of the reporting media outlet is a critical condition for this relationship. Once the outlet has a high reach, the severity of CSI coverage is a boundary condition that further reinforces the effect. Our findings complement existing theory about the risk‐mitigating effect of corporate social responsibility by illuminating the risk‐generating effect of CSI coverage. For executives, these insights suggest complementary strategies for corporate risk management. Managerial summary: This article examines the effect of negative news on financial risk. It shows that negative media articles regarding environmental, social, and governance (ESG) issues increase a firm's credit risk. It also provides a detailed analysis of the impact of an article's reach and severity, i.e., how many readers are exposed to the article and how harshly it criticizes the firm. The results allow to quantitatively assess the risk that emanates from negative ESG news. For executives, three strategies are derived for limiting a firm's exposure to this risk: balancing corporate social responsibility programs with operational safety programs, reporting suboptimal environmental and social performance transparently and proactively, and avoiding acquisition targets and markets with a legacy of negative news.

We study behavior in the race game with the aim of assessing whether teams can create synergies. The race game has the advantage that the optimal strategy depends neither on beliefs about other players nor on distributional or efficiency concerns. Our results reveal that teams not only outperform individuals but that they can also beat the “truth-wins” benchmark. In particular, varying the length of the race game we find that the team advantage increases with the complexity of the game.  相似文献

Innovation speed is widely considered to be a key factor for a firm's ability to maintain competitive advantage. Primarily, empirical evidence has found contradictory interdependencies regarding the role of innovation speed. The prevailing proposition of “the faster the better” has been challenged by results of empirical studies heavily depending on the methodological setup used. In contrast, we propose a model of the complete innovation process to study innovation speed under uncertainty and competition. We find that higher market uncertainty speeds up innovation and encourages firms to innovate incrementally. Strong competition tends to reduce innovation speed and encourages rather radical innovation.  相似文献

Supply shocks in the global gas market may affect countries differently, as the market is regionally interlinked but not perfectly integrated. Additionally, high supply‐side concentration may expose countries to market power in different ways. To evaluate the strategic position of importing countries with regard to gas supplies, we disentangle the import price into different components and characterize each component as price increasing or price decreasing. Because of the complexity of the interrelations in the global gas market, we use an equilibrium model programmed as a mixed complementarity problem (MCP) and simulate the blockage of liquefied natural gas (LNG) flows through the Strait of Hormuz. This enables us to account for the oligopolistic nature and the asymmetry of the gas supply. We find that Japan faces the most severe price increases, as the Japanese gas demand completely relies on LNG supply. In contrast, European countries such as the UK benefit from good interconnection to the continental pipeline system and domestic price taking production, both of which help to mitigate an increase in physical costs of supply as well as in the exercise of market power.  相似文献
