Modelling lottery sales as a function of the mean, standard deviation and skewness of the probability distribution of returns potentially gives insights into how the design of a game could be modified to maximise net revenue. But use of OLS is problematic because the level of sales itself affects values of the moments (and insufficient instruments are available for IV regression). We draw on the concept of a rational expectations equilibrium, developing a new regression model which corrects for endogeneity where the causal impact of the dependent variable on the right-hand side variables is deterministic. We apply the model to data on lotto sales from Spain. Using the Spanish data, we show that results provide more reliable guidance to lottery agencies because accounting for endogeneity leads to significantly different results from OLS and these results have superior performance in out-of-sample forecasting of sales. More generally, results prove consistent with the Friedman-Savage explanation of why people buy lottery tickets and with evidence from racetrack data that ‘bettors love skewness’. 相似文献

In this paper we define manipulation with restricted beliefs as the possibility for some voter to have an insincere preference ordering that dominates the sincere one within the given individual beliefs over other agents’ preferences. We then show that all non-dictatorial voting schemes are manipulable in this sense, up to a given threshold. 相似文献

This paper analyzes demographic determinants of incident experience and risk perception, as well as the relationship between the two, for eight different risk domains. Analyses were conducted by merging the results of a Swedish population-based survey, which includes approximately 15,000 individuals, with demographic and socio-economic register data. Being male was associated with higher incident experience yet a lower risk perception for nearly all risk domains. Lower socioeconomic status was associated with higher incident experience for falls, and being a victim of violence but lower incident experience for road traffic accidents. Lower socioeconomic status was also associated with higher risk perception for falls. On aggregate, ranking the different domains, respondents’ risk perception was in almost perfect correspondence to the ranking of actual incident experience, with the exception that the risk of being a victim of violence is ranked higher than indicated by actual incident experience. On a demographic group level, men and highly educated respondents perceive their risks to be lower than what is expected considering their actual incident experience. 相似文献

Information transparency is a relevant factor nowadays. The current legislation has forced hazardous companies to improve their communication policy with the local community, but this entails the difficulty that each individual has a different need for information. This study considers the main antecedents of need for information to explain these differences. The paper analyses, to our knowledge for the first time, the direct influence of personal beliefs about environmental issues on the individual’s need for information. The research focused on the residents (992) of an area near to a petrochemical complex. The results, derived from the structural equation modelling analysis, confirmed the influence of environmental beliefs, trust in companies and negative affective response on the need for information. In the light of these results, we recommend that the companies of the complex develop a risk communication policy based on personal environmental beliefs, in order to understand the public’s concerns and their needs for risk information. Finally, the analysed companies need to see risk communication as a long-term and ongoing process that involves active dialogue and enables stakeholders’ participation, with the aim of establishing a communication network. 相似文献

The current study examined the relationships of ethical beliefs (i.e., idealism and relativism) with pro-environmental behaviors (direct and indirect) and ethical consumption behavior. The study further examined the moderating role of consumer authenticity in these relationships. Data were collected from individuals (N = 302) using field surveys within three major metropolitan cities of Pakistan. The findings revealed that idealism had a positive relationship with ethical consumption behavior and pro-environmental direct behavior. However, it was not related to pro-environmental indirect behavior. Relativism was positively related to ethical consumption behavior but it was not related to both types of pro-environmental behaviors. Furthermore, consumer authenticity significantly moderated the relationships of idealism with all ethical outcomes. Finally, implications for organizations, marketers and policy makers are discussed. 相似文献

This paper presents a new answer to the old question of how to aggregate individual beliefs. We construct a model which allows agents to take arbitrage opportunities against the aggregated belief by making contingent claims against the states, and the aggregator (market maker) regulates the probability of states. When all claims from the agents are mutually covered for every realization of the state, an aggregation of individual beliefs is thus obtained. We prove the existence and uniqueness of the equilibrium aggregation, and also show that the aggregate belief lies in the convex hull of individual beliefs. This model allows us to address some important problems such as how individual agent’s attitude toward risk and wealth endowment affect the outcome of the aggregation process, and whether the aggregate belief satisfies the well-known properties like equal treatment. 相似文献

文章讨论了加入异质信念后公司特质风险对预期收益率的影响。通过放宽经典Merton模型的假设条件,加入异质信念和卖空限制,重新推导了特质波动率与预期收益率之间的关系。结果表明,在投资者无法多样化投资的前提下,即使考虑了异质信念,公司特质波动率仍然进入资产定价方程,特质波动率与预期收益率之间存在正向关系。 相似文献
