P(enalized)-splines and fractional polynomials (FPs) have emerged as powerful smoothing techniques with increasing popularity in applied research. Both approaches provide considerable flexibility, but only limited comparative evaluations of the performance and properties of the two methods have...

In recent years, considerable research has been devoted to developing complex regression models that can deal simultaneously with nonlinear covariate effects and time trends, unit- or cluster specific heterogeneity, spatial heterogeneity and complex interactions between covariates of different...

This paper uses a German employer-employee matched panel data set to investigate the effect of organizational and technological changes on gross job and worker flows. The empirical results indicate that organizational change is skill-biased because it reduces predominantly net employment growth...

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...

Based on theoretical models of job mobility this paper provides an empirical analysis of job durations in West Germany using information from two cohorts of new entrants to the labor force. We adopt an accelerated failure time model allowing for unobserved heterogeneity. Thereby we combine the...

The IAB employment subsample is now available for researchers in a third, anonymised version. Following the so-called basic file and the regional file from the IAB employment subsample, which encompassed the years 1975 to 1990, the actualized version of the basic file covers now the years 1975...

A growing literature is concerned with the effects of flexible workplace systems or High Performance Work Organizations (HPWOs) on wages. This paper makes use of a new employer-employee-linked panel data set for Germany to examine the effects of adopting HPWOs on wages as well as on the wage...

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...
