The imputation of wages above the contribution limit with the German IAB employment sample

Abstract

"Researchers analyzing wages with the German IAB employment sample are confronted with a censoring problem: The data comes from the social security accounts. Therefore the wages are only given up to the contribution limit of the social security (A documentation of the data set is found in Bender, Haas, and Klose (2000)). To avoid biased estimation the censored wages can be imputed with estimated wages. The estimation can be done with a tobit model. The independent variables of the estimation are for example qualification, region and branch." (Author's abstract, IAB-Doku) ((en))
