Fuzzy-set qualitative comparative analysis
To answer the research questions, we applied fuzzy-set QCA using the QCA package in R [QCA uses its own terminology: for example, “conditions,” a term that is analogous to the term “independent variables” in a correlational model; and “outcome,” a term that is analogous to the term “dependent variable.”The set-theoretic origin of QCA, which distinguishes it from correlational approaches, gives it two analytical advantages for our research aim. First, QCA features conjunctural causation, allowing one to assess the impact of multiple conditions combined [Second, QCA features equifinality, enabling to identify multiple configurations of conditions that are associated with the outcome [
