Does democracy cause gender equality?

Does democracy cause gender equality? To address this question, I use the unexpected Second Vatican Council (1962–65) as part of a shock-based identification strategy. The Second Vatican Council brought forward in time transitions to democracy that would have happened anyway and triggered transitions to democracy that would not otherwise have occurred. I use this plausibly exogenous variation in democracy to offer a causal estimate. According to my baseline specification, one standard deviation increase in democracy leads to three-fifths of a standard deviation increase in gender equality. I also peruse qualitative evidence to sketch a causal mechanism.
