Interpreting Sufficiency in fsQCA: A Reply to Marques and Salavisa (2017)

Abstract

Marques and Salavisa (2017) use fuzzy set qualitative comparative analysis (fsQCA) to analyze age-based labour market dualization in Southern European, Anglo-Saxon and a few Nordic countries. They argue that segmentation at the expense of young outsiders is driven by several factors in non-linear ways: different configurations of deindustrialization, labour market coordination, employment protection, and liberalization can lead to youth outsiderness. We question the validity of their empirical analysis and argue that a more complete interpretation of fsQCA measures of fit does not confirm their conclusions. We use the occasion for a hands-on discussion of how the consistency and PRI scores of the sufficiency solution terms are calculated. A good understanding of these allows the researcher to understand which cases and configurations drive high or low scores, and thus facilitates a better understanding of the results.
