Overreaction to Fearsome Risks 总被引:1,自引:0,他引:1
When risks threaten, cognitive mechanisms bias people toward action or inaction. Fearsome risks are highly available. The availability bias tells us that this leads people to overestimate their frequency. Therefore, they also overreact to curtail the likelihood or consequences of such risks. More generally, fear can paralyze efforts to think clearly about risks. We draw on a range of environmental risks to show the following: (1) Fear leads us to neglect probability of occurrence; (2) As fearsome environmental risks are usually imposed by others (as externalities), indignation stirs excess reaction; (3) We often misperceive or miscalculate such risks. Two experiments demonstrate probability neglect when fearsome risks arise: (a) willingness-to-pay to eliminate the cancer risk from arsenic in water (described in vivid terms) did not vary despite a 10-fold variation in risk; (b) the willingness-to-accept price for a painful but non dangerous electric shock did not vary between a 1 and 100% chance. Possible explanations relate to the role of the amygdala in impairing cognitive brain function. Government and the law, both made by mortals and both responding to public pressures, similarly neglect probabilities for fearsome risks. Examples relating to shark attacks, Love Canal, alar and terrorism are discussed. 相似文献

This paper studies the importance of politicians’ qualification, in terms of education and experience, for fiscal outcomes. The analysis is based on a large panel for 2031 German municipalities for which we have collected information on municipal budgets as well as the election results and qualification levels of mayoral candidates. We principally use a regression discontinuity design focusing on close elections to estimate causal effects. We find that mayors with prior experience in office have a tendency to reduce the level of local public debt, lower total municipal expenditures and decrease the local taxes, even though these results are only significant in some specifications. In contrast, the education level of the mayor exerts no significant effects on the overall fiscal performance of the municipality. The results are partly surprising as both education and experience are shown to matter greatly in the electoral success of mayoral candidates. 相似文献

In this study, we investigate the effects of stock short-sale constraints on options trading by exploiting two US Securities and Exchange Commission rule changes under Regulation SHO: Rule 203 (locate and close-out requirements) and Rule 202T (temporary removal of short-sale price tests). We find that stock short selling activities decrease (increase) significantly after Rule 203 (Rule 202T) implementation, supporting the validity of Rule 203 (Rule 202T) as an exogenous increase (decrease) in short-sale constraints. Options volume increases significantly after Rule 203 went into effect and the result is more pronounced among firms with lower levels of institutional ownership and smaller options bid-ask spreads. Therefore, the evidence from Rule 203 suggests that investors may use options as substitutes for stock short sales when short selling is less feasible or more costly due to the locate and delivery requirements. In contrast, we find no significant change in the options trading volume of pilot stocks during the pilot program of Rule 202T. Overall, our results indicate that the impact of short-sale constraints on options trading varies with the types of constraints affected. 相似文献

The main purpose of this paper is to empirically model the influence of macroeconomic and financial variables on the performance
of risk capital in the US. We start our investigation using a static long-run equilibrium model. In contrast to previous studies,
we analyze the effect of several factors simultaneously within the framework of a vector error correction model (VECM). This
allows us to study short- and long-term interactions to overcome the problem of endogeneity, and to discover causal mechanisms.
The results show that the value of venture capital investments is positively related to industrial production, the exit channel
Nasdaq, and the long-term interest rate. However, the value of venture capital investments is negatively related to the short-term
interest rate. According to the short-term dynamics, VEC Granger causality confirms that only industrial production influences
venture capital performance, while venture capital returns Granger causes Nasdaq performance. 相似文献

Firm stakeholders are paying more attention to the firm risks rather than merely focusing on returns. Among those risks, a firm's ability to repay its debt increasingly becomes a yardstick to evaluate a firm and predict the security level of returning its borrowings. This situation is directly related to a firm's default risk. The current article links the firm's value strategies and capabilities to firm default risk reduction. Specifically, this article conceptualizes and operationalizes a new firm capability, value chain capability, and examines how this capability and two firm value strategies, R&D and advertising, reduce the firm's default risk. Meanwhile, the authors formulate the value chain capability's moderating effects on the relationships between the two value strategies and firm default risk. The findings suggest that value chain capability and advertising help the firm reduce default risk. R&D will have the same effect only when a firm has high value chain capability. 相似文献

Despite the rapid growth of Internet banking (IB), customers in developing countries still hesitate to adopt this technology and its use in the Middle East remains low. This study aims to identify and examine the factors that predict behavioural intention and adoption of IB in Jordan. Four factors – hedonic motivation, habit, self-efficacy and trust – are proposed in a conceptual model. Data was collected by means of a survey with bank customers in Jordan. Structural equation modelling (SEM) was used to analyse the data. The results strongly supported the conceptual model. Further, hedonic motivation, habit, self-efficacy and trust were all confirmed to have a significant influence on behavioural intention. Trust was found to be strongly predicted by both hedonic motivation and self-efficacy. This study provides both academics and practitioners with an insight into the factors that can be used to encourage customer adoption of IB specifically in a Middle East context. 相似文献
