This dissertation consists of three essays in LaborEconomics. The first chapter estimates the costs for establishments of hires andseparations for a panel of German establishments. The panel records the start and thetermination of the employment of all employees in the surveyed establishments,...

In the first essay, we propose a nonparametric testing methodology for jump diffusion models of asset prices with stochastic volatility. We test various parametric specifications against a nonparametric alternative. The test statistic is constructed using the transition densities of the asset...

Using a very large sample of matched author-referee pairs, we examine how the gender of referees and authors affects the former's recommendations. Relying on changing matches of authors and referees, we find no evidence of gender differences among referees in charitableness toward authors; nor...

We measure the impact of individuals' looks on their life satisfaction or happiness. Using five data sets from the U.S., Canada, the U.K., and Germany, we construct beauty measures in different ways that allow putting a lower bound on the true effects of beauty on happiness. Personal beauty...

We consider a functional parameter called the conditional average treatment effect (CATE), designed to capture heterogeneity of a treatment effect across subpopulations when the unconfoundedness assumption applies. In contrast to quantile regressions, the subpopulations of interest are defined...

SUMMARY This paper considers estimation of censored panel‐data models with individual‐specific slope heterogeneity. The slope heterogeneity may be random (random slopes model) or related to covariates (correlated random slopes model). Maximum likelihood and censored least‐absolute...
