QCA FOR DUMMIES

BASICS OF THE QUALITATIVE COMPARATIVE ANALYSIS

Abstract

This paper aims to introduce the QCA (Qualitative Comparative Analysis) method for studies in the social sciences. It starts with a conceptual discussion of the comparative method covering the QCA, its characteristics, and operating logic; then, we present its typologies and its three main variations: Crisp-Set QCA, Multivariate QCA, and Fuzzy-Set QCA. Based on their typologies, we approach different inference and validation strategies for comparative research, and, finally, the limits and precautions to be taken when using this technique.
