Education and the sex of those around you

Persistent Effects of Teacher-Student Gender Matches:

We exploit data from middle schools in Seoul, South Korea, where students and teachers are randomly assigned to classrooms, and find that female students taught by a female versus a male teacher score higher on standardized tests compared to male students even five years later. We also find that having a female math teacher in 7th grade increases the likelihood that female students take higher-level math courses, aspire to a STEM degree, and attend a STEM-focused high school. These effects are driven by changes in students' attitudes and choices.

The Effect of Peer Gender on Major Choice :

This paper investigates how the peer gender composition in university affects students' major choices and labor market outcomes. Women who are randomly assigned to more female peers become less likely to choose male-dominated majors, they end up in jobs where they work fewer hours and their wage grows at a slower rate. Men become more likely to choose male-dominated majors after having had more female peers, although their labor market outcomes are not affected. Our results suggest that the increasing female university enrollment over recent decades has paradoxically contributed to the occupational segregation among university graduates that persists in today’s labor market.

Do High School Sports Build or Reveal Character?
"We do not find consistent evidence of individual benefits reported in many previous studies – once we have accounted for selection, high school athletes are no more likely to attend college, earn higher wages, or participate in the labor force. However, we do find that men (but not women) who participated in high school athletics are more likely to exercise regularly as adults. Nevertheless, athletes are no less likely to be obese."
For people in Japan, happiness isn’t associated with better health
"Feeling positive emotions is good for your physical health, right? There’s certainly evidence in support of the idea. But it’s mostly come from studies of people living in Western countries. Now a study published in Psychological Science, concludes that for people in Japan, it may not be the case."

Which Hat to Wear? Impact of Natural Identities on Coordination and Cooperation
"By priming a fragmenting (ethnic) identity, we find that, compared to the control, participants are significantly less likely to choose high effort in the minimum-effort games, leading to less efficient coordination. In comparison, priming a common organization (school) identity significantly increases the choice of a rational joint payoff maximizing strategy in a prisoner’s dilemma game."
