We use a rigorous three-stage many-analysts design to assess how different researcher decisions—specifically data cleaning, research design, and the interpretation of a policy question—affect the variation in estimated treatment effects. A total of 146 research teams each completed the same causal inference task three times each: first with few constraints,...

We find no effect of the reform on physical or sexual...

We estimate the impact of an exogenous increase in income on the prevalence and counts of intimate partner violence (IPV). We exploit time and family-size variation in the earned income tax credit (EITC) by comparing victimization of women with one child or more with that of women with no children...

The local financing system in Spain makes little distinction between municipalities based on population size. Yet the financial problems facing small municipalities in rural areas differ greatly from those of large cities or municipalities located in metropolitan areas.

The evidence suggests that wealth tax audits do enhance compliance, but the impact is short-lived...

The chapter reviews the economic literature on intimate partner violence (IPV), a widespread human rights violation affecting nearly one in three women globally and generating significant societal costs. It focuses on the relationship between various dimensions of female empowerment and IPV. The chapter begins by outlining key theoretical frameworks—including household...
