The Internet's effect on women's coauthoring rates and academic job market decisions: The case of political science

The late 1990s saw the introduction and spread of the Internet and email. For social scientists, these technologies lowered communication costs and made inter-department collaboration much easier. Using women in political science as a case study, we show that this change has disproportionately affected women in two ways. First, women have increased the rate at which they co-author journal articles faster than their male counterparts. Second, the lowered communication costs have made women more willing to take jobs at smaller departments because it is now easier to work with colleagues at other universities.     

Are boys discriminated in Swedish high schools?

Girls typically have higher grades than boys in school and recent research suggests that part of this gender difference may be due to discrimination of boys in grading. We rigorously test this in a field experiment where a random sample of the same tests in the Swedish language is subject to blind and non-blind grading. The non-blind test score is on average 15% lower for boys than for girls. Blind grading lowers the average grades with 13%, indicating that personal ties and/or grade inflation are important in non-blind grading. But we find no evidence of discrimination against boys in grading. The point estimate of the discrimination effect is close to zero with a 95% confidence interval of ±4.5% of the average non-blind grade.
