Knowledge that Transforms

In the Netherlands, an immediate baby boom followed the end of WWII and the baby bust of the 1930s. I propose a novel application of the bunching methodology to examine whether the war shifted the timing of fertility or changed women's completed fertility. I disaggregate the number of births by age for cohorts of mothers, and estimate counterfactual distributions of births by exploiting that women experienced the war at different ages. I show that the rise in fertility after the liberation did not make up for the "missed" births that did not occur prior to the war, as fertility would have been 9.4% higher in absence of WWII.

How do short absences from work affect workers’ labor trajectory? We use linked employer-employee administrative data from Hungary, with rich administrative health records, and use unexpected and mild accidents with no permanent labor productivity losses as exogenous drivers of short absences. Our Differencein-Differences results show that, relative to the counterfactual of no accident, even short (3–6-months long) periods of absence due to accidents decrease wages for up to two years by 1.5 percent, and workers end up with lower-paying firms. Missed opportunities to move to higher-paying firms account for 7–37 percent of the wage loss over a two-year period.
