Alternative view on the location of the World's Economic Centre of Gravity

Danny Quah from the London School of Economics has produced a paper The Global Economy's Shifting Centre of Gravity, dated August 2010, presenting an alternative view as to the location of the World's Economic Centre of Gravity (WECG) to that of Grether and Mathys (see previous post).

This has the WECG located just south of Izmir, Turkey (rather than north of Norway) and moving East. Maybe this provides a partial explanation for the current success of the rapidly growing airlines Emirates and Turkish.
