What drives gender wage gaps – and how best to close them – remains a contested topic of economic research. Using data from matched employer-employee registers in France from 1995 to 2015, this column finds that discrepancies in pay are driven largely by men and women working in different firms rather than similar men and women being paid differently at the same firm. Understanding why the share of the gender gap ascribed to firms persists over time and across cohorts remains an essential policy puzzle for further reducing wage disparities.

Large internal wage disparities between cities are a common feature in countries around the world. Using data from Germany, this column argues that one key driver of this is rising assortative matching of high-quality workers and plants in large cities. One promising strategy to reduce spatial wage disparities is to improve matching within small cities.

This paper evaluates the role that cities play on individual productivity in China. The authors' results strongly support the productivity gains that can be expected from further migration and urbanisation in China.
