Thomas Piketty (French: [tɔˈma pikɛˈti]; born on 7 May 1971) is a French economist who works on wealth and income inequality. He is a professor (directeur d'études) at the École des hautes études en sciences sociales (EHESS), professor at the Paris School of Economics and Centennial professor at the London School of Economics new International Inequalities Institute.
He is the author of the best-selling book Capital in the Twenty-First Century (2013), which emphasises the themes of his work on wealth concentrations and distribution over the past 250 years. The book argues that the rate of capital return in developed countries is persistently greater than the rate of economic growth, and that this will cause wealth inequality to increase in the future. He considers that to be a problem, and to address it, he proposes redistribution through a progressive global tax on wealth.
