%0 Report %A Stillman, Steven %A Velamuri, Malathi %T Are Personality Traits Really Fixed and Does It Matter? %D 2020 %8 2020 Jun %I Institute of Labor Economics (IZA) %C Bonn %7 IZA Discussion Paper %N 13342 %U https://www.iza.org/index.php/publications/dp13342 %X A nascent but burgeoning literature examines the importance of non-cognitive skills in determining success across many facets of life. The majority of these papers treat these skills as fixed traits for adults. We estimate the impact of a number of life events on the Big Five personality traits and locus of control. A subset of life events have large impacts on these non-cognitive skills, especially on locus of control. For some events, these impacts persist in the medium-run. We then demonstrate that treating personality traits as fixed can lead to biased estimates of their relationship with socioeconomic outcomes. %K personality %K non-cognitive skills %K life events %K fixed
