All OECD countries except the United States offer at least four months of paid maternity leave, and the average duration of mandated paid maternity leave has increased steadily from 1970 to the present. There is some evidence that paid leave policies above a certain duration negatively impact...

Many countries remain far from achieving gender equality in the classroom. Using data from 126 countries, we characterize the evolution of gender gaps in low- and middle-income countries between 1960 and 2010. We document five facts. First, women are more educated today than 50 years ago in...

This article reviews and summarizes current reproduction and replication practices in political science. We first provide definitions for reproducibility and replicability. We then review data availability policies for 28 leading political science journals and present the results from a survey...
