Piketty Rejects ‘Ridiculous’ Allegations of Data Flaws

Thomas Piketty rejected allegations that data behind his best-selling book on inequality are flawed as fellow economists spoke up in his defense.

Piketty, the French economist whose book “Capital in the Twenty-First Century” has transformed the debate on the causes and consequences of disparities in income and wealth, called a Financial Times analysis of his statistics “just ridiculous.” He added in an e-mail to Bloomberg News that “there’s no mistake or error” in his work.
