Kenneth_Arrow--Martin_Feldstein

Kenneth Joseph Arrow (August 23, 1921 – February 21, 2017) was an American economist, mathematician, writer, and political theorist. Along with John Hicks, he won the Nobel Memorial Prize in Economic Sciences in 1972.
In economics, Arrow was a major figure in post-World War II neoclassical economic theory. Many of his former graduate students have gone on to win the Nobel Memorial Prize themselves. His most significant works are his contributions to social choice theory, notably "Arrow's impossibility theorem," and his work on general equilibrium analysis. He has also provided foundational work in many other areas of economics, including endogenous growth theory and the economics of information.
