Kenneth Joseph “Ken” Arrow was born on August 23, 1921, and died on February 21, 2017.

He was an American economist, writer, and political theorist.

Arrow was the joint winner of the Nobel Memorial Prize in Economics with John Hicks in 1972.

Until now he is the youngest person to have received this award, at 51.

As a economist, Arrow was a figure in post-World War II neo-classical economic theory.

Some of his former graduate students have gone on to win the Nobel Memorial Prize themselves.

Arrow’s most significant works are his contributions to social choice theory, notably “Arrow’s impossibility theorem”, and his work on general equilibrium analysis.

Arrow has also provided foundational work in many other areas of economics, including endogenous growth theory and the economics of information.

He remained active on the international scene through a variety of initiatives including trustee of Economists for Peace and Security and a member of the Advisory Board of Incentives for Global Health, the not-for-profit behind the Health Impact Fund until his death.

Kenneth Arrow passed away at 95 years old.
