Ariel Rubinstein (Hebrew: אריאל רובינשטיין; born April 13, 1951) is an Israeli economist who works in economic theory, game theory and bounded rationality.

Ariel Rubinstein is a professor of economics at the School of Economics at Tel Aviv University and the Department of Economics at New York University. He studied mathematics and economics at the Hebrew University of Jerusalem, 1972–1979 (B.Sc. Mathematics, Economics and Statistics, 1974; M.A. Economics, 1975; M.Sc Mathematics, 1976; Ph.D. Economics, 1979).

In 1982, he published "Perfect equilibrium in a bargaining model",^[1] an important contribution to the theory of bargaining. The model is known also as a Rubinstein bargaining model. It describes two-person bargaining as an extensive game with perfect information in which the players alternate offers. A key assumption is that the players are impatient. The main result gives conditions under which the game has a unique subgame perfect equilibrium and characterizes this equilibrium.

Rubinstein was elected a member of the Israel Academy of Sciences and Humanities (1995),^[2] a Foreign Honorary Member of the American Academy of Arts and Sciences in (1994)^[3] and the American Economic Association (1995). In 1985 he was elected a fellow of the Econometric Society,^[4] and served as its president in 2004.^[5]

In 2002, he was awarded an honorary doctorate by the Tilburg University.^[6]

He has received the Bruno Prize (2000), the Israel Prize for economics (2002),^[7][8] the Nemmers Prize in Economics (2004),^[9][10] the EMET Prize (2006).^[11] and the Rothschild Prize (2010).^[12]
