这篇综述梳理了智力或认知能力与风险态度、耐心以及投资表现之间关系的研究,发现认知能力较高的人通常更有耐心,但风险厌恶与认知能力的关联尚存争议。
Abstract Do more intelligent investors take better economic decisions than less intelligent ones? Is risk attitude, in particular risk/loss aversion, linked to cognitive ability? Does an investor's cognitive ability impact his/her patience? Is financial performance positively linked to investor's intelligence? These research questions have become highly relevant with the development of behavioral economics and behavioral finance, following the recognition that humans are not homo economicus. This paper reviews the several strands of literature devoted to answering the above questions. We first discuss the barely debated definitions and measures of intelligence/cognitive ability used in psychology, economics, and finance. We then review the results related to the (controversial) link between risk aversion and cognitive ability. We observe that the literature provides clear results for patience; individuals with a higher level of cognitive ability being more patient on average. Finally, we review the contributions linking (successfully or not) portfolio choice and financial performance to cognitive ability.
