"Questions on income in surveys are prone to two sources of errors that can cause bias if not addressed adequately at the analysis stage. On the one hand, income is considered sensitive information and response rates on income questions generally tend to be lower than response rates for other...

"Linking data from different sources can be used to compensate for the weaknesses characteristic for the single sources and therefore significantly increase the potential for analyses. This requires that linking data implies no consequences that cancel out the advantages. Considering this...

"To compare different missing data techniques, in this paper I use a survey where participants were among other things asked permission for combining the survey with administrative data (record linkage). For those who refuse their permission I set their survey answers to missing, creating...

"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...

"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 paper investigates the predictive power of a new survey implemented by the Federal Employment Agency (FEA) for forecasting German unemployment in the short run. Every month, the CEOs of the FEA's regional agencies are asked about their expectations of future labor market developments. We...
