Are Cities the New Growth Escalator?
Urban areas tend to have much more productive labor and higher salaries than rural areas, and there are vast differences across urban areas. Areas with high salaries and high productivity tend to have employers that invest in much more research and development than areas with low salaries and low productivity. This paper addresses two questions. First, it discusses the causes of these vast geographical differences in wages, human capital, and innovation. The second part of the paper discusses regional economic development policies.
