Xavier Sala i Martín (also Sala-i-Martin in English) was born on June 17, 1962 in Cabrera de Mar, Catalonia, Spain and is a Spanish-American economist, and a professor at Columbia University.
Sala i Martin earned his degree from the Autonomous University of Barcelona in 1985, and his Ph.D. from Harvard University in 1990, both in economics. 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, which he still visits for a term, every summer.
Sala i Martin is one of the leading economists in the field of economic growth and is consistently ranked among the most-cited economists in the world for works produced in the 1990s. 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. 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, 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.
