Propensity score matching provides an estimate of the effect of a 'treatment' variable on an outcome variable that is largely free of bias arising from an association between treatment status and observable variables. However, matching methods are not robust against 'hidden bias' arising from...

In den letzten Jahren hat sich eine unified theory aus der Arbeitsökonomik heraus-gebildet, in der die Meinung vorherrscht, dass die Kombination makroökonomi- scher Schocks und flexibler Arbeitsmarktinstitutionen in den USA eine starke Zu-nahme der Lohnungleichheit verursacht habe, während...

Using newly collected data from the General Social Survey, we compare levels of segregation by race and along other potential dimensions of social cleavage for ties defined in terms of trust and acquaintanceship. We further estimate the size of the trust network and compare its size and...

Comparisons of well-being across societies depend both on the amount of inequality at the national level and also on the national average level of well-being. Comparisons between the U.S. and western Europe show that inequality is greater in the U.S. but that average GDP per capita is also...

Despite the striking reversal of the gender gap in education, women pursue science, technology, engineering, and mathematics (STEM) degrees at much lower rates than those of their male peers. This study extends existing explanations for these gender differences and examines the role of the high...

We develop a polygenic index for individual income and examine random differences in this index with lifetime outcomes in a sample of ~35,000 biological siblings. We find that genetic fortune for higher income causes greater socio-economic status and better health, partly via intervenable...

Despite the striking reversal of the gender gap in educational attainment and the near–gender parity in math performance, women pursue science and engineering (S/E) degrees at much lower rates than their male peers do. Current efforts to increase the number of women in these fields focus on...
