Abstract
Testosterone is the main androgen affecting sexual differentiation in-utero. According to the twin testosterone transfer hypothesis, a female fetus sharing uterus with a male is exposed to higher testosterone levels. Likewise, a male fetus sharing uterus with another male is exposed to higher levels. In this short thesis, wages of twins in opposite-sexed pairs are compared to wages of twins in same-sexed pairs, to entangle the possible effect of biological sex on the labour market. However, the effects in the current research set-up also include possible socialization effects of being raised with a male or female sibling, which could be migrated by controlling with non-twin sibling couples. The sample investigated is twins born in Sweden... (More)
Testosterone is the main androgen affecting sexual differentiation in-utero. According to the twin testosterone transfer hypothesis, a female fetus sharing uterus with a male is exposed to higher testosterone levels. Likewise, a male fetus sharing uterus with another male is exposed to higher levels. In this short thesis, wages of twins in opposite-sexed pairs are compared to wages of twins in same-sexed pairs, to entangle the possible effect of biological sex on the labour market. However, the effects in the current research set-up also include possible socialization effects of being raised with a male or female sibling, which could be migrated by controlling with non-twin sibling couples. The sample investigated is twins born in Sweden between 1935-1958, from the Swedish Twin Registry, to which income register data has been matched from 1968-2007. The results for females indicate that having a twin brother increase wage and the results for males suggest that having a twin brother decrease wage. The original idea of investigating the testosterone transfer hypothesis on the labour market is from a working paper by Gielen, Holmes and Myers (2013). (Less)
