Existing models in the parimutuel betting literature typically explain betting data by either assuming a single, representative bettor with certain risk preferences or by assuming that a number of risk neutral bettors compete strategically within a game theoretic framework. We construct a theoretical framework of parimutuel markets in which we model both strategic interaction and individual bettor risk preferences, distinguishing between sophisticated insiders and recreational outsiders. We solve this model analytically for the optimal insider betting amount in a static symmetric Nash equilibrium. A new data set of 126 million individual horse race bets in New Zealand from 2006 to 2014 allows us to calibrate the model. We find that insiders (those betting $100 or more) outperform outsiders by 7.5% in terms of realized returns. The best fit of the model to the data is obtained when insiders are assumed to be risk neutral and to have an information advantage of 0.08 in probability terms. This finding provides empirical support for the common assumption of risk neutrality in strategic interaction models of parimutuel betting.  相似文献

This experimental article helps to understand the motives behind cooperation in the prisoner’s dilemma. It manipulates the pay-off in case both players defect in a two-player, one-shot prisoner’s dilemma and explains the degree of cooperation by a combination of four motives: efficiency, conditional cooperation, fear and greed. All motives are significant but some become only significant if one controls for all remaining ones. This seems to be the reason why earlier attempts at explaining choices in the prisoner’s dilemma with personality have not been successful.  相似文献

We examine optimal production and export decisions of a firm facing exchange rate uncertainty, where the firm's management is not only risk averse but also regret averse, i.e., is characterized by a utility function that includes disutility from having chosen ex post suboptimal alternatives. Experimental and empirical results support the view that managers tend to be regret averse. Under regret aversion a negative risk premium need not preclude the firm from exporting which would be the case if the firm were only risk averse. Exporting creates an implicit hedge against the possibility of regret when the realized spot exchange rate turns out to be high. The regret‐averse firm as such has a greater ex ante incentive to export than the purely risk averse firm. Finally, we use a two‐state example to illustrate that the firm optimally exports more (less) to the foreign country than in the case of pure risk aversion if the low (high) spot exchange rate is more likely to prevail. Regret aversion as such plays a crucial role in determining the firm's optimal allocation between domestic sales and foreign exports.  相似文献

National governments invest in initiatives aimed at encouraging rural entrepreneurship on the assumption that it contributes to competitiveness and employment. Empirical findings about one such initiative in Thailand reveal the nature of entrepreneurship difficulties and the diverse expressions of entrepreneurship failure, not only in the sense of termination of activities and exit but also entrepreneurs’ inability to meet the objectives and aims of the initiative. Significant attitudinal inadequacies such as risk aversion, passivity and over-reliance on the public sector complement entrepreneurship resource weaknesses in explaining rural entrepreneurship difficulties and failure. Findings demonstrate inadequacies of one-size-fits-all policies seeking to encourage rural entrepreneurship by failing to address the needs and capabilities of the involved entrepreneurs. The discussion also extends current research, first, by studying rural entrepreneurship within an institutional framework in an emerging market context; second, by conceptualizing rural entrepreneurship failure and attitudinal drivers of such failure; third, by documenting and analysing the nature, sources and consequences of the distinct constructs of ‘rural entrepreneurship difficulties’ and ‘rural entrepreneurship failure’; and finally, by presenting a revised theorization of ‘failure’ in entrepreneurship research which recognizes the diverse forms that failure may assume.  相似文献

Research summary: This article draws on identity control theory and a study of acquisition premiums to explore how CEO celebrity status and financial performance relative to aspirations affect firm risk behavior. The study finds that celebrity CEOs tend to pay smaller premiums for target firms, but these tendencies change when prior firm performance deviates from the industry average returns, thereby leading these CEOs to pay higher premiums. The study also finds that the premiums tend to be even larger when celebrity CEOs have more recently attained celebrity status. Taken together, these findings contribute to identity control theory and CEO celebrity literatures by suggesting that celebrity status is a double‐edged sword and that the internalization of celebrity status by CEOs strongly influences the decision‐making of CEOs. Managerial summary: The purpose of this article is to examine how CEO celebrity status and financial performance relative to aspirations affect the size of acquisition premiums. The study finds that celebrity CEOs tend to pay smaller premiums for target firms. However, when celebrity CEOs' prior firm performance is either better or worse than the industry average, these CEOs pay higher premiums. This situation is exacerbated when the CEO has only recently been crowned a celebrity. In effect, these CEOs feel great pressure to match the inflated performance expectations that come with celebrity status. These findings suggest that being a celebrity is a double‐edged sword. The implication here is that CEOs who have recently been crowned a celebrity should be aware of these pressures and cope accordingly. Copyright © 2015 John Wiley & Sons, Ltd.  相似文献

Research summary: We draw on behavioral agency theory to explain how decision heuristics associated with CEO stock options interact with firm slack to shape the CEO's preference for short‐ or long‐term strategies (temporal orientation). Our findings suggest CEO current option wealth substitutes for the influence of slack resources in encouraging a long‐term orientation, while prospective option wealth enhances the positive effect of slack on temporal orientation. Our theory offers explanations for non‐findings in previous analysis of the relationship between CEO equity based pay and temporal orientation and provides the insights that CEO incentives created by stock options (1) enhance the effect of available slack upon temporal orientation and (2) can both incentivize and de‐incentivize destructive short‐termism, depending upon the values of current and prospective option wealth. Managerial summary: We explore how compensation design can play a role in affecting the CEO's preference for short‐ or long‐term strategic projects. When the CEOs have accumulated option wealth, they are more likely to invest in the long term. Yet when they have a large number of recently granted options with the potential to generate significant wealth in the event of successful risk taking, the CEO is more likely to prefer the short term in order to achieve personal wealth gains more quickly. The more liquid assets the firm holds, the weaker both of the aforementioned effects. An implication for boards is that they should anticipate CEO short‐termism if the CEO has been granted new options, underlining the potential negative consequences of option compensation.

Estimation of the inputs is the main problem when applying portfolio analysis, and Markov regime-switching models have been shown to improve these estimates. We investigate whether the use of two-regime models remains superior across a range of values of risk aversion and transaction costs, in the presence of skewness and kurtosis and no short sales. Our results for US data suggest that, due to differences in their risk preferences and transactions costs, most retail investors may prefer to use one-regime models, while investment banks may prefer to use two-regime models.  相似文献

This study investigates the effect of risk aversion of single-parent households with at least one child under 18 on life insurance ownership. Analysing the 1992–2013 Survey of Consumer Finances datasets, we found that the likelihood of owning term life insurance decreases as risk aversion increases, but the likelihood of owning cash-value life insurance increases as risk aversion increases. Smokers were less likely to own term life insurance but more likely to own cash-value life insurance than comparable non-smokers.  相似文献

Due to the popularity of online travel agency (OTA) booking platforms, OTAs display diverse information, including features of products, on their websites. Based on choice architecture literature, this study aimed to examine the effect of product quality and price sorting (vs. non-sorting) on extreme option choice aversion and identify the moderating effect of displays that made it difficult to read information. The results of a series of four experimental studies (total n = 2838 online panel members) demonstrated that the tendency to choose the non-extreme or middle-attributed options was stronger when quality and price were displayed sorted (vs. non-sorted). It was theorized that easy comparison of multiple options leads to decision-making. The positive effect of quality and price sorting on extreme option choice aversion was significantly reduced when customers had difficulty reading the displayed information.  相似文献
