残疾与风险偏好:来自越南的实验与调查证据

Disability and risk preferences: Experimental and survey evidence from Vietnam
The Economic Journal · 2024 · Jan Priebe、Ute Rink、Henry Stemmler

中文摘要

我们利用长达十年的个体层面面板数据以及来自实地实验室实验的数据,考察在越南经历家庭残疾事件是否会影响经济风险偏好。我们发现,经历过家庭残疾事件的个体比无此经历的个体表现出更强的风险规避行为。在考察潜在作用机制时,我们证明了家庭残疾冲击会导致财富下降,进而与更高程度的风险规避相关。此外,我们提供的证据表明,认知机制——恐惧情绪与信念更新(对未来变得更加悲观)——是残疾冲击影响风险偏好的另一个渠道,甚至可能是更重要的渠道。

Abstract

Abstract We investigate whether experiencing a disability incidence in the household affects economic risk preferences in Vietnam, leveraging (i) ten years of individual-level panel data and (ii) data from a lab-in-the-field experiment. We find that individuals who experience a disability event in the household behave in a more risk-averse manner than individuals without such an experience. Examining potential underlying mechanisms, we demonstrate that a household disability shock leads to lower wealth, which in turn is related to higher levels of risk aversion. Furthermore, we provide evidence that cognitive mechanisms—fearful emotions and the updating of beliefs (becoming more pessimistic about the future)—are another, perhaps even more important channel through which disability shocks affect risk preferences.
