47 p, 304.5 KB Growth in a Cross-Section of Cities : Location, Increasing Returns or Random Growth? / González Val, Rafael (Universitat de Barcelona) ; Olmo, Jose (City University London) ; Xarxa de Referència en Economia Aplicada (XREAP)
This article analyzes empirically the main existing theories on income and population city growth: increasing returns to scale, locational fundamentals and random growth. To do this we implement a threshold nonlinearity test that extends standard linear growth regression models to a dataset on urban, climatological and macroeconomic variables on 1,175 U. [...]
