  text: "Qualitative comparative analysis (QCA) enables researchers in international
    management to better understand how the impact of a single explanatory factor
    depends on the context of other factors. But the analytical toolbox of QCA does
    not include a parameter for the explanatory power of a single explanatory factor
    or “condition”. In this paper, we therefore reinterpret the Banzhaf power index,
    originally developed in cooperative game theory, to establish a goodness-of-fit
    parameter in QCA. The relative Banzhaf index we suggest measures the explanatory
    power of one condition averaged across all sufficient combinations of conditions.
    The paper argues that the index is especially informative in three situations
    that are all salient in international management and call for a context-sensitive
    analysis of single conditions, namely substantial limited diversity in the data,
    the emergence of strong INUS conditions in the analysis, and theorizing with contingency
    factors. The paper derives the properties of the relative Banzhaf index in QCA,
    demonstrates how the index can be computed easily from a rudimentary truth table,
    and explores its insights by revisiting selected papers in international management
    that apply fuzzy-set QCA. It finally suggests a three-step procedure for utilizing
    the relative Banzhaf index when the causal structure involves both contingency
    effects and configurational causation.\r\n"
