Rosche, B. (2024). Micro-level determinants of macro-level outcomes. The micro-macro link with empirical methods.

Explaining how macro-level outcomes emerge from their constituting parts at the micro-level is a complex undertaking. In empirical research, however, statistical methods that feature trivial aggregation functions dominate because methods to study more complex aggregation processes remain underdeveloped. In this thesis, I contribute to the development of empirical-statistical methods for the study of micro-macro links. … Read more

Rosche, B. (2024). A multilevel model for coalition governments: Uncovering party-level dependencies within and between governments.

Coalition research increasingly emphasizes party-level explanations of coalition outcomes. However, this work does not account for the complex multilevel structure between parties and governments: many parties participate in multiple governments and governments often comprise multiple parties. In this paper, I demonstrate that this crisscrossing structure creates dependencies among observations both across and within governments. If … Read more

Rosche, B. (2024). Treatment effects on within-group and between-group inequality. A causal decomposition approach.

Rising inequality has been linked to growing disparities within and between economic strata. Yet, existing approaches to analyzing inequality often disregard within-group inequality and are limited in addressing causal questions about why inequality is changing. This paper introduces a causal approach to examining how treatment variables impact within-group, between-group, and total inequality. The method permits … Read more
