Empirical research based on panel data has to pay special attention to measurement errors. Utility maximization often yields nonlinear decision rules in which measurement errors enter in a multiplicative way. The usual strategy to deal with them consists of taking log-linear approximations of...

This article develops a model of food demand in which the quality and quantity of food purchased and the inter-purchase time are determined simultaneously. We use this model to explore the relationship between a household's cereal purchases and its demographic variables. Households eligible to...

Paneldaten haben gegenüber Querschnittsdaten zahlreiche Vorteile. Amtliche Daten sind zudem eine wichtige Quelle für die Sozial- und Wirtschaftswissenschaften. Viele amtliche Datenerhebungen sind als Panel konzipiert und durchgeführt oder können zu Panels zusammengefügt werden. Diese Arbeit...

In empirical studies it often happens that some variables for some units are far away from the other observations in the sample. These extreme observations, or outliers, often have a large impact on the results of statistical analyses - conclusions based on a sample with and without these units...

This paper provides a self-contained introduction to the British Household Panel Survey (BHPS), concentrating on aspects relevant to analysis of the distribution of household income. I discuss BHPS design features and how data on net household income are derived. The BHPS net household income...

We assess whether the probability of a sample member participating at a particular wave of a panel survey is greater if the same interviewer is deployed as at the previous wave. Previous research on this topic mainly uses non-experimental data. Consequently, a) interviewer change is generally...

Against a background of rising costs and increasing competition, it is becoming more and more difficult for the small and medium-sized firms of the German mechanical engineering industry to be economically successful. The thesis that rapidly changing markets, products and production processes...

Many validation studies deal with item-nonresponse and measurement error in earnings data. In this paper we explore motives of respondents for the failure to reveal earnings using the German Socio-Economic Panel (GSOEP). GSOEP collects socio-economic information of private households in the...

A particular shortcoming of panel surveys is potential bias arising from selective attrition. Based on data from the German Socio-Economic Panel Study (SOEP) we analyze potential artifacts (level, structure, inequality of income) by comparing results from two independently drawn panel...

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...
