摘要

In an economy experiencing endogenous economic growth and exogenous population growth, we explore two main themes: how urbanization affects efficiency of the growth process and how growth affects patterns of urbanization. Localized information spillovers promote agglomeration and human capital accumulation fosters endogenous growth. Individual city sizes grow with local human capital accumulation and knowledge spillovers; and city numbers generally increase, which we demonstrate is consistent with empirical evidence. We analyze whether local governments can successfully internalize local dynamic externalities. In addition, we explore how growth involves real income differences across city types and how urbanization can foster income inequality.
