Paul Romer – New Growth Economist – Paul believes that the city not the nation state is the appropriate resolution to think about development taking his inspiration from the way that Hong Kong and then specially designated mainland cities have been the engine for China’s growth. His plan for Cuba is to do the same kind of thing using Guantanamo Bay as a special development zone administered by Canada and Cuba jointly, incidentally removing a political headache for the USA along the way. For Paul innovation in development is all about changing the rules that shape that development.
