This paper examines the union membership wage premium among private sector employees covered by collective bargaining agreements. Using Current Population Survey data for 2000–2003, the author not only estimates the conditional mean wage premium—the metric on which most previous...

Using data from a randomized experiment, we find that having a female teacher lowers the math test scores of female primary school students in disadvantaged neighborhoods. Moreover, we do not find any effect of having a female teacher on male students’ test scores (math or reading) or female...

This paper revisits the effect of high school leadership activities on young men’s earnings. Using several data sets and extending a recently developed econometric technique, we show that even a small amount of selection on unobservables explains the entire high school leadership effect on...

Using data from a randomized experiment and fixed effect quantile regression (FEQR), we examine the effects of having a TFA teacher on test scores across the entire achievement distribution of primary school students in disadvantaged neighborhoods. While we generally find that TFA teachers...

Following an identification strategy that allows us to largely eliminate unobserved student and teacher traits, we examine the effect of homework on math, science, English and history test scores for eighth grade students in the United States. Noting that failure to control for these effects...
