Xavier Sala i Martín (also Sala-i-Martin in English) is an American and Spanish economist, who is a professor of economics at Columbia University. Sala i Martin is one of the leading economists in the field of economic growth.[2]

Born in Cabrera de Mar, Catalonia, Spain, Sala i Martin earned a degree in economics from the Autonomous University of Barcelona in 1985. He completed his PhD in Economics from Harvard University in 1990.[3]

In addition to working at Columbia, he has been a professor at Yale University, Harvard University, and the Universitat Pompeu Fabra in Barcelona and the Barcelona Graduate School of Economics, where he usually visits for a term, every summer.

Professional work[edit]

Sala i Martin is one of the leading economists in the field of economic growth[4] and is consistently ranked among the most-cited economists in the world for works produced in the 1990s.[5][6] His works include the topics of economic growth, development in Africa, monetary economics, social security, health and economics, convergence, and classical liberal thinking, with his book Liberal economics for non-economists.[7][8] The "liberal" in the title should be understood in the classic liberal/libertarian sense.

He has constructed an estimate of the world distribution of income,[9] which he has then used to estimate poverty rates and measures of inequality. The conclusions of this study offered a new point of view for two reasons. Firstly, the United Nations and the World Bank used to believe that although poverty rates were falling, the total number of poor people was increasing. He claimed that both were falling. Secondly, the United Nations and the World Bank believe that individual income inequalities were on the rise. He claimed that they were not.[10]

Sala i Martin is the author of the economic growth textbook Apuntes de Crecimiento Economico (in Spanish) and the co-author (with Robert Barro) of the textbook Economic Growth (original in English; translated into French, German, Spanish, Chinese, and Japanese).

Sala i Martin is, along with Elsa V. Artadi, the author of the Global Competitiveness Index, used since 2004[11] by the Global Competitiveness Report published by the World Economic Forum, an index that ranks 142 countries by their level of economic competitiveness.

Other activities[edit]

He was a board member at FC Barcelona and treasurer of the club between 2004 and 2010. He was the president of the club during the electoral process of 2006.

He is the founder of Umbele: A Future for Africa, a nonprofit organization that promotes economic development in Africa.

He is a columnist for the Spanish newspaper La Vanguardia. He makes weekly appearances in the Catalan radio network RAC 1 and in the television show Divendres[12][13][14][15][16] of TV3. He also contributes to CNN.[17][18]

He supports Catalan independence and gives conferences around Catalonia, in name of the pro-independence association that he and other university teachers created for that purpose (Col·lectiu Wilson)[19].


He has been recognized with a Distinguished Teacher in Graduate Economics award three times at Columbia and Yale, with the 2004 King Juan Carlos I Prize (a biannual prize given to the best economist in Spain and Latin America), and the 2006 Lenfest Prize awarded to the best teacher at Columbia University.

On 15 January 2017, Martin was listed by UK-based company Richtopia at number 14 in the list of 100 Most Influential Economists.[20][21]
