In my asymmetric-information model of layoffs, high-productivity workers are more likely to be recalled to their former employer and may choose to remain unemployed rather than to accept a low-wage job. In this case, unemployment can serve as a signal of productivity, and duration of...

While much of the literature that investigates the part-time (PT) / full-time (FT) hourly wage differential and its causes focuses on average effects, very few studies analyze the heterogeneous effects of PT work across different subgroups, despite the policy relevance of understanding channels...

What happens to children's long-run cognitive development when introducing universal high-quality childcare for 3-year olds mainly crowds out maternal care? To answer this question we exploit a natural experiment framework and employ a difference-in-difference approach. We find sizable...

Using a differences-in-differences approach and controlling for individual unobserved heterogeneity, we evaluate the impact of a 1999 law that granted all workers with children younger than 7 years old protection against a layoff if the worker had previously asked for a work-week reduction due...

Using data from social security records on Spanish males, we investigate the wage effects of working under a fixed-term contract. In a first step, we provide fixed-effects estimates of the wage effect of working under a fixed-term contract for low-skilled, medium-skilled, and high-skilled men...

We show that the OLS and fixed‐effects (FE) estimators of the popular difference-in-differences model may deviate when there is time varying panel non-response. If such non-response does not affect the common-trend assumption, then OLS and FE are consistent, but OLS is more precise. However,...
