Cognitive and non-cognitive skills are important determinants of labor market outcomes, but are often unobserved. We propose a proxy for these skills derived from item non-response information and a procedure to test its validity. Exploiting a unique data-collection feature of an Australian...

With the world-wide spread of the internet in the 1990s, the conduction of web or e-mail surveys became popular in research. Although these surveys provide fast data collection and reduced costs, results may suffer from biases due to the survey mode. While a variety of studies concerning mode...

This paper focuses on fraud detection in surveys using Socio-Economic Panel (SOEP) data as an example for testing newly methods proposed here. A statistical theorem referred to as Benford's Law states that in many sets of numerical data, the significant digits are not uniformly distributed, as...

The definition and operationalization of wealth information in population surveys and the corresponding microdata requires a wide range of more or less normative assumptions. However, the decisions made in both the pre- and post-data-collection stage may interfere considerably with the...

The dissertation elaborates on topics that are related to (i) intergenerational transfers of wealth and to (ii) how government ideology and elections influence outcomes (income inequality and budget consolidation) and political processes (fiscal planning and policy advice). The dissertation...

This study provides new evidence on top income shares in Germany from the period of industrialization to the present. Income concentration was high in the nineteenth century, dropped sharply after World War I and during the hyperinflation years of the 1920s, and increased rapidly throughout the...

We study the dynamics of income inequality, capital concentration, and voting outcomes before 1914. Based on new panel data for Prussian counties and districts we re-evaluate the key economic debate between Marxists and their critics before 1914. We show that the increase in inequality was...

Earlier research on poverty failed to provide us with consistent measures of its prevalence across space and time. This is due to the limitations of the available sources and to the difficulty of applying to them the poverty definitions of modern social science. This article discusses different...

German history over the past 125 years has been turbulent. Marked by two world wars, revolutions and major regime changes, as well as a hyperinflation and three currency reforms, expropriations and territorial divisions, it provides unique insights into the role of country-specific shocks in...
