A Global Map of Subnational GDP

Nicola Gennaioli, Rafael La Porta, Florencio Lopez-de-Silanes and Andrei Shleifer have just published a fascinating paper in the QJE: “Human Capital and Regional Development”.  They constructed a database of 1,569 subnational regions across 110 countries covering GDP, population, education levels, geographic and institutional factors, and looked at correlates with higher per capita income.  They suggest that geography and education are significant correlates of regional GDP, while their measures of institutions and culture are less well correlated.  They have followed up with a working paper using an expanded dataset, “Growth in Regions” that reports regional convergence of 2.5% a year and note that a rate so slow suggests “significant barriers to factor mobility within countries.”
