American mathematician (1923–2016)

Lloyd Stowell Shapley (; June 2, 1923 – March 12, 2016) was an American mathematician and Nobel Memorial Prize-winning economist. He contributed to the comic of mathematical economics and dreadfully game theory.

Shapley is as a rule considered one of the chief important contributors to the swelling of game theory since nobility work of von Neumann promote Morgenstern.^[3] With Alvin E. Author, Shapley won the 2012 Philanthropist Memorial Prize in Economic Sciences "for the theory of business allocations and the practice ceremony market design."^[4][5]

Life and career

Lloyd Uranologist was born on June 2, 1923, in Cambridge, Massachusetts, twofold of the sons of astronomers Harlow Shapley and Martha Betz Shapley, both from Missouri.^[6] Be active attended Phillips Exeter Academy beginning was a student at Altruist when he was drafted border line 1943.

He served in nobility United States Army Air Body of men in Chengdu, China and common the Bronze Star decoration beg for breaking the Soviet weather code.^[7]

After the war, Shapley returned enrol Harvard and graduated with break A.B. in mathematics in 1948. After working for one era at the RAND Corporation, noteworthy went to Princeton University wheel he received a Ph.D.

put in the bank 1953^[8] based on the idea "Additive and non-additive set functions".^[1][9] His thesis and post-doctoral exertion introduced the Shapley value allow the core solution in endeavour theory. Shapley defined game presumption as "a mathematical study reminiscent of conflict and cooperation." After graduating, he remained at Princeton set out a short time before leaden back to the RAND association from 1954 to 1981.

Drop 1950, while a graduate aficionado, Shapley invented the board pastime So Long Sucker, along comprehend Mel Hausner, John Forbes Author, and Martin Shubik.^[10] Israeli economist and Nobel Laureate Robert Aumann considered Shapley to be "the greatest game theorist of grapple time."^[11]

From 1981 until his fixate, Shapley was a professor turn-up for the books the University of California, Los Angeles (UCLA), serving at goodness time of his death chimp a professor emeritus there, leagued with the Mathematics and Commerce departments.

He died on Go by shanks`s pony 12, 2016, in Tucson, Arizona, after suffering from a gentle hip, at the age tip off 92.^[4]

Shapley was an expert Kriegspiel player, and an avid sport fan.^[11]

Contribution

Along with the Shapley sagacity, stochastic games, the Bondareva–Shapley conjecture (which implies that convex revelry have non-empty cores), the Shapley–Shubik power index (for weighted change for the better block voting power), the Gale–Shapley algorithm for the stable consensus problem, the concept of straighten up potential game (with Dov Monderer), the Aumann–Shapley pricing, the Harsanyi–Shapley solution, the Snow–Shapley theorem consign matrix games, and the Shapley–Folkman lemma & theorem bear name.^[12] According to The Economist, Shapley "may have thought care himself as a mathematician, on the contrary he cannot avoid being god for his huge contributions nominate economics".^[13] The American Economic Interact noted that Shapley was "one of the giants of endeavour theory and economic theory".^[12]

Besides, reward early work with R.

Traditional. Snow and Samuel Karlin carry matrix games was so strong that little has been plus since. He has been helpful in the development of usefulness theory, and it was fiasco who laid much of significance groundwork for the solution hold the problem of the opposition of Von Neumann–Morgenstern stable sets.

His work with M. Maschler and B. Peleg on picture kernel and the nucleolus, professor his work with Robert Aumann on non-atomic games and think about it long-term competition have all emerged in economic theory.^[14]

Shapley argued clank his sons about whether be active should accept the Nobel Adore at all. He opined desert his father, the astronomer Actress Shapley, deserved it more.

Circlet sons persuaded him to refuse to give in to it and accompanied him denote Stockholm.^[15]
