The analysis finds firm innovation to be highly concentrated at the city level. It finds that increases in city population boost firms’ propensity to introduce process and product innovations and undertake research and development activities. The paper also shows that knowledge spillovers are an important channel through which agglomeration effects occur.40EconomicsEducationIndustry and tradeTertiary educationUrban development
