Choice, preference and rationalizability in pareto’s theory of economic behavior

Pareto initiated the shift of economic theory from utility/preference to choice in order to fill a gap between theoretical and empirical economics. His suggestions for an empirically-oriented theory of choice were to be developed decades later in the literature on revealed preference and on the conditions of equivalence between preference-based and choice-based axiomatic structures. In the process, however, substantial departures from Pareto’s implicit design of the situation of choice were introduced. In this paper, the conditions for the rationalizability of choice are re-defined so that they fit the type of situation that Pareto had in mind. The result is that the main consistency axioms of standard choice theory have to give way to a different combination of axioms that concern decisiveness as well as consistency.

Prospect theory in the wild: how good is the nonexperimental evidence for prospect theory?

ABSTRACT

Prospect 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.     

迁移理论的基础:“理解人口学”的分析框架

根据学者布如金所提出的人口理论研究新范式,在对其进行概括和拓展的基础上,提出了“理解人口学”的分析框架。同时综合部分迁移研究的成果,融合不同研究方法,从四个层次:迁移行为的概念假设、迁移行为的发端、迁移行为的外部环境和迁移行为的时间纬度,为人口迁移行为分析提供了-个跨学科的研究视野。     

The Effect of Respondent Experience/Knowledge in the Elicitation of Contingent Values: An Investigation of Convergent Validity,Procedural Invariance and Reliability

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.     

Candidate stability and nonbinary social choice

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.

社区商业文化价值的开发

社区商业文化产生于社区商业细致入微的服务及相对稳定的服务对象两者之间积极互动的过程。社区商业经营活动的过程就是社区商业文化形成的过程。质优价宜的商品、全面细致的服务、社区活动的参与和促销宣传活动的结合,强化了社区网点与社区居民之间的亲和关系。充分发挥社区商业文化吸引消费、引导消费的价值,必须从战略的高度对待选址、服务配套、人员配备、参与社区建设等经营管理的问题。     

Planning Your Own Debt

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.
