Xavier Sala-i-Martin Edit Profile

also known as Xavier Sala i Martín


Xavier Sala-i-Martin is an American economist.


Sala-i-Martin is a professor of economics at Columbia University. In addition to working at Columbia, he has been a professor at Yale University, Harvard University, and the Universitat Pompeu Fabra in Barcelona (which he still visits for a term every summer).

With a career spent both teaching, researching world economics, and consulting with governments and international financial institutions (he regularly advises the World Bank and the International Monetary Fund), professor Sala-i-Martin is in the privileged position to be able to offer decision makers wishing to do business in today’s volatile markets essential information on how to be competitive and innovative.

As the chief economic advisor of the Center for Global Competitiveness and Performance of the World Economic Forum (WEF), he is the author and the intellectual father of the prestigious Global Competitiveness Index (GCI). The index, published annually by the WEF in the Global Competitiveness Report, measures and ranks the competitiveness of all the countries in the world and recommends competitiveness strategies to their decision makers. Professor Sala-i-Martin’s GCI is the most closely followed index on global economic and business competitiveness in the world. Governments and business leaders use it to evaluate and design current and future strategic competitiveness policies of their countries and corporations.

Between 2003 and 2010, Xavier was a member of the board and president of the economics commission of FC Barcelona and, therefore, contributed to the creation of what many experts consider the best soccer team ever assembled. Indeed, in 2009, FC Barcelona won all 6 championships in which it participated. No other team in the world has ever accomplished such a feat.

An experienced teacher, Xavier is able to put across complex ideas in an easy to understand format using colorful and entertaining examples. With a reputation for humorous and enlightening presentations, Xavier is in great demand as a conference speaker at leading financial events around the world.
