This is an advanced methodological course on set-theoretic methods for the social sciences. While the spectrum of a set-theoretic methods is broad, including techniques such as Mill’s meth- ods or typological theory, this course primarily focuses on the crisp-set and fuzzy-set versions of Qualitative Comparative Analysis (QCA). Invented by Charles Ragin , this technique has undergone various modifications, improvements, and ramifications [Ragin, 2000, 2008]. These methods are applied in fields as diverse as political science, public policy, international relations, sociology, business and management studies, or even musicology (see www.compasss.org). This course aims at enabling students to produce a publishable QCA of their own. In order to achieve this, this course provides both the formal set theoretical underpinnings of QCA and the technical and research practical skills necessary for performing a QCA. The practical part is exclusively performed in the R software environment.
