"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...

"By arranging the Microcensus (the German Labour Force Survey) as a set of panel data it is possible to carry out longitudinal analyses. As participation in the survey is obligatory by law, the cases of non-response are minimal. For that reason the number of cases available is comparably high,...

"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...

"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...

"The geographical distribution and persistence of regional/local unemployment rates in heterogeneous economies (such as Germany) have been, in recent years, the subject of various theoretical and empirical studies. Several researchers have shown an interest in analysing the dynamic adjustment...

"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...

"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 many large data sets of economic interest, some variables, as wages, are top-coded or right-censored. In order to analyze wages with the German IAB employment sample we first have to solve the problem of censored wages at the upper limit of the social security system. We treat this problem...

"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...

"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...
