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

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

This paper proposes a new perspective on systematic deviations from purchasing power parity. Panel evidence for OECD countries shows that international financial integration increases the national price level under managed exchange rate regimes and lowers the price level under floating exchange rates. An open economy sticky-price model reproduces these findings by relating them to the possibility of insurance against consumption losses in internationally integrated financial markets. The utilization of insurance is reflected by relative price adjustments which manifest themselves in changes of the national price level. The direction of relative price adjustments, however, depends on the extent to which insurance is used under different exchange rate regimes: under a peg, financial integration raises the national price level; under a float, however, financial integration lowers the national price level.  相似文献
