Many empirical studies specify outcomes as a linear function of endogenous regressors when conducting instrumental variable (IV) estimation. We show that tests for treatment effects, selection bias, and treatment effect heterogeneity are biased if the true relationship is non-linear. These...

We investigate public preferences for equity-enhancing policies in access to early child care, using a survey experiment with a representative sample of the German population (n ≈ 4, 800). We observe strong misperceptions about migrant-native inequalities in early child care that vary by...

Why are children with lower socioeconomic status (SES) substantially less likely to be enrolled in child care? We study whether barriers in the application process work against lower-SES children — the group known to benefit strongest from child care enrollment. In an RCT in Germany with...

We document new facts on the distribution of male fertility and its relationship with men's labor market outcomes. Using Norwegian registry data on all births since 1967, we show that rates of male childlessness in recent cohorts are 72% among the lowest five percent of earners but only 11%...

Children with lower socioeconomic status (SES) tend to benefit more from early child care, but are substantially less likely to be enrolled. We study whether reducing behavioral barriers in the application process increases enrollment in child care for lower-SES children. In our RCT in Germany...

We provide the first causal evidence of discrimination against migrants seeking child care. We send emails from fictitious parents to 18, 000 early child care centers across Germany, asking if there is a slot available and how to apply. Randomly varying names to signal migration background, we...

We find that the lifecycle employment profiles of nonwestern male labor migrants who came to Norway in the early 1970s diverge significantly from those of native comparison persons. During the first years after arrival almost all of the immigrants worked and their employment rate exceeded that...
