This study explores how researchers’ analytical choices affect the reliability of scientific findings. Most discussions of reliability problems in science focus on systematic biases. We broaden the lens to emphasize the idiosyncrasy of conscious and unconscious decisions that researchers make...

This study investigates researcher variability in computational reproduction, an activity for which it is least expected. Eighty-five independent teams attempted numerical replication of results from an original study of policy preferences and immigration. Reproduction teams were randomly...

Which governments implement interventionist or liberalising labour policy reforms, and does the economic context matter? Drawing on the previous literature on government ideology and public policy, we hypothesise that leftist governments are more likely to implement interventionist labour...

What is the purpose of lengthy negotiations when a coalition government forms? Do they make a difference in coalition policy-making? Negotiations that produce policy agreements between coalition partners have been suggested to strengthen the capacity of coalition governments to make policy...

This study explores how rising costs of climate mitigation policies shape climate policy support differentially for the ideological left and right. To this end, we randomly manipulate the consumption costs associated with four different climate mitigation policies and study how different cost...

Das komplexer gewordene bundesdeutsche Parteiensystem und die Angleichung in der Stärke der Parteien bei Wahlen führt zu einem ebenfalls komplexeren Koalitions- und Regierungsbildungsprozess auf Bundes- wie Landesebene. Diese Kurzanalyse präsentiert die programmatischen Profile der im...

This paper studies the effects of political factors, mainly partisanship, on corporate taxes in the past 30 years - a period of intensifying competitive pressure in Europe. Extending the Zodrow-Mieszkowski model by decision-makers who have ideological preferences yields the hypothesis that...

The GLES Open Science Challenge 2021 was a pioneering initiative in quantitative political science. Aimed at increasing the adoption of replicable and transparent research practices, it led to this special issue. The project combined the rigor of registered reports—a new publication format in...
