In order to analyze the gender wage gap with the German IAB-employment sample we have to solve the problem of censored wages at the upper limit of the social security system. We treat this problem as a missing data problem. We regard the missingness mechanism as not missing at random (NMAR,...

In this paper, we remove one serious drawback of the IAB employment sample impeding its applicability to the estimation of earnings frontiers: the censoring of the income data, by multiple imputation. Then, we estimate individual potential income with stochastic earnings frontiers, and we...

The linked employer-employee dataset of the IAB (LIAB) is created by matching the data of the IAB establishment panel and the process-produced data of the Federal Employment Services (in particular the IAB). The distinctive feature of these data is the combination of information about...
