Diese Dissertation untersucht, welchen Effekt die Bereitschaft von Arbeitnehmern zu räumlicher Mobilität auf die Höhe der Entlohnung hat. Nach einer Einführung über die vorhandene Literatur und den theoretischen Hintergrund der internationalen Mobilitätsforschung vergleicht der Autor die...

"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, 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...

"Die Arbeit untersucht, wie stabil die Ergebnisse der jüngst vom Institut für Arbeitsmarkt- und Berufsforschung veröffentlichten Berechnungen zur Stillen Reserve für den Zeitraum von 1970 bis 2002 hinsichtlich der zentralen Modellannahme über die Höhe der Vollbeschäftigung sind. Dazu...

"This report documents reasons, methods and results of the general revision 2014 of the IAB working-time measurement concept (AZR) for the period from 1991 to 2013. The AZR which is part of the German system of national accounts (VGR) provides long comparable time series for industry-specific...

"This paper investigates the time-varying relationship between German output and employment growth, in particular their decoupling in recent years. We estimate a correlated unobserved components model that allows for both persistent and cyclical time variation in the employment impact of GDP as...

"The article analyses how the hidden labour force has developed in the recent past and what role the far-reaching modifications ensuing from the labour market reforms of 2005 (Hartz IV) have played. Estimations published by IAB in 2005 are used as a starting point. On the basis of these...

"Methods for the analysis of linked employer-employee data are not yet available in standard econometrics packages. In this paper, we make the fixed-effects methods developed orginally by Abowd, Kramarz, Margolis and others more accessible, where possible, and show how they can be implemented in...

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