Joseph Stiglitz

Professor, Columbia University
U.S.

The outspoken, Nobel Prize-winning economist is a professor at Columbia University in New York and founder of the Initiative for Policy Dialogue, a think tank. Stiglitz served as chief economist for the World Bank and has advised President Obama on economic policy, but he has also been fiercely critical of some of the Administration's actions, especially the handling of the bank bailouts. At Davos, he has praised Obama's proposed banking reforms but worried they don't go far enough. And while Stiglitz welcomed the President's focus on job creation in his State of the Union address, he called it "a little late." Stiglitz thinks the U.S. economy needs a second infusion of stimulus focused on investment.
