"Further education and training activities are considered to be recalled only with difficulty. Therefore non-formal and informal training activities have mostly not been collected in retrospective surveys. Within the framework of the IAB-ALWA study 'Working and Learning in a Changing World' also...

"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...

"Event history calendars (EHC) have proven to be a useful tool to collect retrospective autobiographic life course data. One problem is that they are only standardized to some extent. This limits their applicability in large-scale surveys. However, in such surveys a modularized retrospective...

"For micro-datasets considered for release as scientific or public use files, statistical agencies have to face the dilemma of guaranteeing the confidentiality of survey respondents on the one hand and offering sufficiently detailed data on the other hand. For that reason a variety of methods to...

"Recently, there has been a renewed interest in the agglomeration wage differential. One of the open research question is whether wage differences between large cities and the rural country are due to unobserved differences in regional price levels. In this paper information on regional price...

"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...
