In this Catalan name, the first or paternal surname is Sala and the second or maternal family name is Martín; both are generally joined by the conjunction "i".
Xavier X. Sala i Martín[2] (also Sala-i-Martin in English) is a Catalan economist and professor of economics at Columbia University. Sala i Martin is one of the leading economists in the field of economic growth.[3]
Sala i Martin is one of the leading economists in the field of economic growth[3] and is consistently ranked among the most-cited economists in the world for works produced in the 1990s.[4][5] 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 and Non-Liberals.[6][7] 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,[8] 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.[9]
Sala i Martin is the author of the economic growth textbook Apuntes de Crecimiento Economico[10] and the co-author (with Robert Barro) of the textbook Economic Growth.[11]
He often collaborates with Catalan media to support the independence of Catalonia from Spain. In 2014 he had a public confrontation with José Manuel Barroso, the president of the European Commission, reproaching him the lack of support towards a democratic resolution of the conflict between Spain and Catalonia.[14]
