@TechReport{iza:izadps:dp15012, author={Lent, Max van}, title={Fathering Daughters and Personality}, year={2022}, month={Jan}, institution={Institute of Labor Economics (IZA)}, address={Bonn}, type={IZA Discussion Paper}, number={15012}, url={https://www.iza.org/index.php/publications/dp15012}, abstract={The big five personality traits develop over a person's lifetime. There is some suggestive evidence that major life events - such as getting married, being fired from a job, and having children - affect personality. However, these associations cannot be interpreted as causal. This is the first paper that studies the causal effect of a life event - the gender of the first-born child - on the big five personality trait scores of fathers. Using yearly longitudinal data (2008 - 2020) I find that having a first-born daughter instead of son increases fathers' extraversion. The gender of the first child also affects labor market outcomes for fathers. Fathers of first-born daughters earn 127 euro more per month (i.e. 6.9% of the average monthly wage). This effect is not driven by changes in the number of hours worked or job switches.}, keywords={family structure;fertility;life events;human capital;big five personality traits;labor market outcomes}, }
