Mounting evidence indicates that power-sharing supports transitions to democracy. However, the resulting quality of democracy remains understudied. Given the increasing global spread of power-sharing, this is a crucial oversight, as prominent critiques accuse it of a number of critical deficiencies. The present article advances this literature in two ways. First, it offers a comprehensive discussion of how power-sharing affects the quality of democracy, going beyond specific individual aspects of democracy. It argues that power-sharing advances some of these aspects while having drawbacks for others. Second, it offers the first systematic, large-N analysis of the frequently discussed consequences of power-sharing for the quality of democracy. It relies on a dataset measuring the quality of democracy in 70 countries worldwide, combining it with new fine-grained data for institutional power-sharing. The results indicate that power-sharing is a complex institutional model which privileges a particular set of democratic actors and processes, while deemphasizing others.
