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 find important determinants of productivity and ineffciency. The data suffer from nonresponse in the most important variables (output, capital and labor) leading to the loss...

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...

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...

Data fusion techniques typically aim to achieve a complete data file from different sources which do not contain the same units. Traditionally, this is done on the basis of variables common to all files. It is well known that those approaches establish conditional independence of the specific...

Zum Vergleich ausgewählter Missing Data Techniken nutzt dieses Papier eine Befragung, in der u. a. die Zustimmung zum Record Linkage der Befragungs- mit administrativen Prozessdaten abgefragt wurde. Bei nicht zustimmenden Befragten, werden ihre gegebenen Antworten auf 'fehlend' gesetzt, um so...

The basic concept of multiple imputation is straightforward and easy to understand, but the application to real data imposes many implementation problems. To define useful imputation models for a dataset that consists of categorical and of continuous variables with distributions that are...

Biografische Kalender (EHC) haben sich als ein nützliches Instrument zur Erfassung retrospektiver autobiografischer Lebensverlaufsdaten erwiesen. Problematisch ist allerdings, dass biographische Kalender nur zu einem gewissen Grad standardisiert sind, was deren Einsetzbarkeit in...

Weiterbildungsaktivitäten gelten als schwer erinnerbare Ereignisse. Daher wurde bislang auf die retrospektive Erhebung nicht-formaler und informeller Weiterbildungsaktivitäten weitgehend verzichtet. Im Rahmen der IAB-Studie 'Arbeiten und Lernen im Wandel (ALWA)' stehen jedoch auch kurze und...

The international literature studies non-take-up behavior of eligible populations to evaluate the effectiveness of government programs. A major challenge in this literature is the measurement error regarding benefit take-up. Measurement error is typically addressed by structural assumptions in...
