Personality Traits Across the Life Cycle: Disentangling Age, Period and Cohort Effects*
通过系统规范检验分离年龄、时期和队列效应，发现不同队列的人格特质随年龄变化呈现稳定但非常数的年龄曲线，且存在显著的时期差异，对经济学家理解人格特质的稳定性有参考价值。
Abstract Economists increasingly recognise the importance of personality traits for socio-economic outcomes, but little is known about the stability of these traits over the life cycle. Existing empirical contributions typically focus on age patterns and disregard cohort and period influences. This paper contributes novel evidence for the separability of age, period and cohort effects for a broad range of personality traits based on systematic specification tests for disentangling age, period and cohort influences. Our estimates document that, for different cohorts, the evolution of personality traits across the life cycle follows a stable, though non-constant, age profile, while there are sizeable differences across time periods.
