Structured additive regression (STAR) models provide a flexible framework for modeling possible nonlinear effects of covariates: They contain the well established frameworks of generalized linear models (GLM) and generalized additive models (GAM) as special cases but also allow a wider class of...

We exploit administrative data on young German workers and their employers to study the long-term effects of an early job loss. To account for non-random sorting of workers into firms with different turnover rates and for selective job mobility, we use changes over time in firm- and age-specific...

Recent research suggests that much of the cross-firm variation in measured productivity is due to differences in use of advanced management practices. Many of these practices - including monitoring, goal setting, and the use of incentives - are mediated through employee decision-making and...

This paper provides quasi-experimental estimates of the causal effect of long-term unemployment on wages. Using standard job search theory, the paper derives and tests conditions on reemployment wages under which Unemployment Insurance (UI) extensions can be used as instrumental variables (IV)...

This paper estimates the causal effect of long-term unemployment on wages. Job search theory implies that if Unemployment Insurance (UI) extensions do not affect wages conditional on the month of unemployment exit, then reservation wages do not bind on average. Then, UI extensions affect mean...
