The Self-Fulfilling Property of Trust: An Experimental Study

A person is said to be ‘trust responsive’ if she fulfils trust because she believes the truster trusts her. The experiment we report was designed to test for trust responsiveness and its robustness across payoff structures, and to discriminate it from other possible factors making for trustworthiness, including perceived kindness, perceived need and inequality aversion. We elicit the truster’s confidence that the trustee will fulfil, and the trustee’s belief about the truster’s confidence after the trustee receives evidence relevant to this. We find evidence of strong trust responsiveness. We also find that perceptions of kindness and of need increase trust responsiveness, and that they do so only in conjunction with trust responsiveness.      

Updating Subjective Risks in the Presence of Conflicting Information: An Application to Climate Change

Willingness to support public programs for risk management often depends on individual subjective risk perceptions in the face of uncertain science. As part of a larger study concerning climate change, we explore individual updated subjective risks as a function of individual priors, the nature of external information, and individual attributes. We examine several rival hypotheses about how subjective risks change in the face of new information (Bayesian updating, alarmist learning, and ambiguity aversion). The source and nature of external information, as well as its collective ambiguity, can have varying effects across the population, in terms of both expectations and uncertainty.JEL Classification  D8, Q51, Q54

银行理财赎回潮背后的流动性风险隐忧及应对

长期的低收益率与刚性兑付使得客户对银行理财产品的风险形成了保本保息的扭曲认识。理财产品的规范化与监管新规的执行引起了理财产品的大幅亏损,导致客户的不满及银行与客户关系的恶化。理财产品风险分级与客户风险类型不匹配可能是问题背后的潜在原因。为此,本文重新审视和检验商业银行理财风险测评的效果。通过行为实验,本文将风险测评问卷、经典的彩票选择测试和新兴的炸弹诱导测试方法进行对比。研究发现风险测评问卷度量的风险厌恶程度显著低于炸弹诱导测评,但与彩票选择测评无显著差异。三种测评方法的结果对风险追求客户的分类表现一致,但对风险厌恶客户的分类存在差异。另外,风险测评问卷将大部分客户划分为稳健与谨慎两类,导致客户类型的区分度不高。客户风险分类是风险测评的核心目的,因此银行需要更好地理解不同测评方法的差异,并慎重地选择测评方法。本研究为解决理财新规下的新问题提供了可能的思路,并为进一步改进理财风险测评提供了建议。
