RT Generic T1 Three pillars of urbanization : migration, aging, and growth A1 Grafeneder-Weissteiner,Theresa A1 Prettner,Klaus A1 Südekum,Jens WP 2018/03/05 AB Economic development in industrialized countries is characterized by rising per capita GDP, increasing life expectancy, and an ever larger share of the population living in cities. We explain this pattern within a regional innovation-driven economic growth model with labor mobility and a demographic structure of overlapping generations. The model shows that there is a natural tendency for core-periphery structures to emerge in modern knowledge-based economies.
