Name That Economist

Do you know me? I am a Harvard trained economist and later became the youngest tenured professor ever at Harvard at the age of 28. Both of my parents are economists and two of my uncles are Nobel prize winning economists. Who am I?

Congratulations to Matt Hickman on being the first to identify Larry Summers as the mystery economist. Lawrence (Larry) Summers is the current Director of the White House's National Economic Council. His past positions include Secretary of the US Treasury, Chief Economist for the World Bank, and President of Harvard University.
