Cities of light and economic power
Richard Florida picks up my mention of the growing role of city-states in the global economy on his blog. He mentions an interesting study that suggests that 40 mega-regions with output of more than $100bn produce more than 66 per cent of world output.
Almost as interesting is that the study identifies economically powerful regions by night-time light emissions seen on satellite photographs. It is always fascinating to look at such photographs and see, for example, the dispiriting lack of night-time light across vast swathes of Africa.
