"In this paper, stochastic production frontier models are estimated with IAB establishment data from waves 2002 and 2003 to analyze productivity and inefficiency. The data suffer from nonresponse in the most important variables (output, capital and labor) leading to the loss of 25 % of the...

"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...

"This paper presents the project 'Treatment Effects and Prediction' (TrEffeR) of the Federal Employment Agency (Bundesagentur für Arbeit - BA). One of the tasks of the project is to provide estimates of the effectiveness of active labor market policy measures for management purposes. The...

In multivariate datasets missing values due to item nonresponse may occur on any or all variables. Since nonrespondents often differ systematically from respondents deletion of incomplete cases would lead to substantial bias as far as inference is intended to the population of all cases rather...
