Economic inequalities spatial patterns in a sustainable world, a complex systems approach

Prof. Gerard WEISBUCH, Ecole Normale Supérieure Paris, France. We discuss the possible World patterns of economic activity after the transition to a sustainable and stationary economy. Our main concern is the economy of energy, most probably the limiting factor of economic development. Should we expect a strongly contrasted world with of economic activity after one or several economically active regions as nowadays? Or a more equitable repartition of wealth and economic activity? We here demonstrate how computations can reduce the set of possible scenarios and conclude that energy transportation cost is the most influential factor.
