In zahlreichen großen Datensätzen von wissenschaftlichem Interesse sind einige Variablen, wie z. B. die Lohnhöhe, top-coded oder rechtszensiert. Zur Analyse von Löhnen auf der Grundlage der IAB-Beschäftigtenstichprobe muss zunächst das Problem der, an der Beitragsbemessungsgrenze der...

This paper illustrates the effects of item-nonresponse in surveys on the results of multivariate statistical analysis when estimation of productivity is the task. To multiply impute the missing data a data augmentation algorithm based on a normal/Wishart model is applied. Data of the German IAB...

In this paper, stochastic production frontier models are estimated with IAB establishment data from waves 2002 and 2003 to analyze productivity and inefficiency. The data suffer from nonresponse in the most important variables (output, capital and labor) leading to the loss of 25 % of the...
