Abstract:

We use a newly assembled sample of 1,528 regions from 83 countries to compare the speed of per capita income convergence within and across countries.  Regional growth is shaped by similar factors as national growth, such as geography and human capital.  Regional convergence rate is about 2% per year, comparable to that between countries.   Regional convergence is faster in richer countries, and countries with better capital markets.  A calibration of a neoclassical growth model suggests that significant barriers to factor mobility within countries are needed to account for the evidence.
