Introduction: Self-assessed health (SAH) is a frequently used measure of individuals' health status. It is also prone to reporting heterogeneity. To control for reporting heterogeneity objective measures of true health need to be included in an analysis. The topic becomes even more complex for...

Estimation procedures for ordered categories usually assume that the estimated coefficients of independent variables do not vary between the categories (parallel-lines assumption). This view neglects possible heterogeneous effects of some explaining factors. This paper describes the use of an...

Due to reasons such as the capacity to govern and social stability a good understanding of citizens preferences and their informal coalitions is extremely important. Because preferences for redistribution are difficult to measure identification of latent subgroups becomes non-trivial. Moreover,...

In 2001, the voluntary additional Riester pension scheme was implemented in Germany. Financial subsidies should incentivize people to increase their private pension savings. In this paper, we hypothesize that these publicly subsidized savings mainly replace existing not subsidized savings and...

Die staatlich geförderte Riester-Rente beschäftigt Politik und Wissenschaft seit ihrer Einführung vor zehn Jahren. Für eine wissenschaftliche Analyse der Akzeptanz und der Anreizmechanismen ist eine angemessene Datengrundlage notwendig. Die vorliegende Analyse zeigt, dass der förderfähige...

The correct definition of the product market and of the geographic market is a prerequisite for assessing market structures in antitrust cases. For hospital markets, both dimensions are controversially discussed in the literature. Using data for the German hospital market we aim at elaborating...

Standardised interpolated path analysis (SIPA) is a method to investigate negotiation processes making different negotiation histories comparable. Due to its interpolation approach, researchers employing SIPA must take data quality and potential information loss into account to maximise the...
