By 2020, London is expected to leapfrog Paris and become Europe's richest city as measured by GDP. London's 3% growth rate is high for a major city in the developed world. London is ranked as the No. 1 city on MasterCard's Centers of Commerce index, owing to the vast volume of its financial markets. It's comparable to New York in equities and commodities trading but is larger in bond and derivatives trading. The downside? It's expensive. The purchasing power of the average Londoner is less than their New York peers.

Today the economy of Paris is bigger than London's. But sluggish growth in this old-world capital has it slowly losing ground. By 2020 it will have been passed by London. We'll always have Paris, yes, but by 2020 its economy will be little larger than rapidly-growing Mexico City.
