Sports participation is a leading environmental explanation of the male advantage in some spatial skills. We exploit the large increase in females' high school sports participation due to Title IX to test this hypothesis. We relate Title IX induced increases in females' sport participation to...

We present new evidence of the correlation of height with important socioeconomic outcomes, finding the height profile is significantly non linear at mean height, especially for males. We trace this non linearity back to the adult height profiles of cognitive scores from the teenage and...

Research on sex differences in humans documents gender differences in sensory, motor and spatial aptitudes. These aptitudes, as captured by Dictionary of Occupational Titles (DOT) codes, predict the occupational choices of men and women in the directions indicated by this research. We simulate...

We revisit the US evidence of the association of height with socioeconomic status. We document non linear height profiles that are different for males and females. For males the profile is a spline function with a single node at mean height. Below mean height there is a sharply positive slope...

While many jurisdictions ban teacher strikes on the assumption that they harm students, there is surprisingly little research on this question. The majority of existing studies make cross section comparisons of students who do or do not experience a strike, and report that strikes do not affect...
