“…We decided to perform a fuzzy set qualitative comparative analysis (fsQCA) (Ragin, 2000;Schneider & Wagemann, 2012;Thomann & Maggetti, 2020) on the different cases. QCA methods have been used in recent work in international relations (Ide and Mello, 2022), political economy, public administration, and regulatory governance ranging from explaining economic belief changes of eurozone leaders (Swinkels, 2020), to EU national reform programs (Cacciatore et al, 2015) redistribution objectives of regulatory agencies (Donadelli & van der Heijden, 2024), national regulatory responses to the global financial crisis (Young & Park, 2013) and closest to the present paper, de facto independence of regulatory agencies after delegation (Maggetti, 2007). 9 The motivation for this choice of inference method is threefold: First, the limited number of EU countries that experienced a housing boom in the period of interest (17) makes a regression analysis unsuitable, while a small-N qualitative case study is not practical either.…”
