ABSTRACTProspect theory is widely thought to be one of the best-confirmed accounts of human decision-making under risk. There are numerous claims in the literature that various kinds of nonexperimental, observational evidence provide strong support for prospect theory. We investigate the veracity of these claims using a set of philosophy of science morals and a careful delineation of models of choice under risk, focussing on the extant versions of prospect theory and their various components. We challenge the claim that prospect theory is well supported because it explains the equity premium puzzle. In addition, we analyse a major international survey thought to support prospect theory and argue that the support is questionable, both for statistical reasons and because the evidence itself is mixed. Our analyses highlight some important ideas in the philosophy of science and caution against strong claims about support for prospect theory that rely on nonexperimental, observational evidence. 相似文献

Tests of convergent validity and procedural invariance were used to investigate whether individuals lacking direct experience with a commodity can provide valid responses to contingent-valuation questions eliciting ex post use values. Convergent validity between samples with and without experience was shown to hold for dichotomous-choice responses, but not for open-ended responses. 相似文献

参与、不确定性与投资秩序的生成和演化——解读投资者动机和预期的另一个视角 总被引:6,自引:0,他引:6
“中国投资者动机和预期调查数据分析”课题组 《经济研究》2002,(2)
不同于现有主流理论把投资者的动机和预期理解为投资者实现其效用最大化的计算过程 ,本文认为投资者的动机和预期表明投资者对于投资决策的一种参与 ,并在此基础上提出一个解释框架。这一解释框架把投资者动机和预期所包含的对于投资决策的参与态度及感受定义为参与指数 ,不同的参与指数形成不同的投资者群体 ,而不同投资者群体的互动 ,决定着对投资决策最终发生实际作用的投资秩序的生成与演化 ,不确定性正是刻划了投资秩序生成与演变的主观性和非设计性。 相似文献

Summary. The requirement that a voting procedure be immune to the strategic withdrawal of a candidate for election can be formalized
in different ways. Dutta, Jackson, and Le Breton (Econometrica, 2001) have recently shown that two formalizations of this candidate stability property are incompatible with some other
desirable properties of voting procedures. This article shows that Grether and Plott's nonbinary generalization of Arrow's
Theorem can be used to provide simple proofs of two of their impossibility theorems.

We model the Danish market for mortgage backed securities with a two-factor interest rate model and use a stochastic programming approach to analyse how an individual home-owner should initially compose and subsequently readjust his mortgage in an optimal way. Results show that the 'rules of thumb' used by financial institutions are reasonable, although best suited for more aggressive mortgagors, for whom the delivery option is of some value. More risk-averse investors should also re-adjust frequently, but use more diversified portfolios. Results are insensitive to whether a one- or two-factor model is used, provided the former is suitably calibrated. 相似文献

Willingness to take on risk is influenced by the presence of fair and unfair background risks for decision makers who are risk vulnerable as defined by Gollier and Pratt [1996], for these decision makers are more risk averse when they possess such an uninsurable background risk. We present an alternative derivation of the index of local vulnerability based on Diamond and Stiglitz [1974] compensated increases in risk, such that risk aversion increases with the introduction of any small fair background risk if and only if the index of local vulnerability is positive. We establish that the increase in risk aversion is greater for those who are more vulnerable as measured by the index of local vulnerability. 相似文献
