Roger Myerson is an American economist and Nobel laureate, recognized for his contributions to game theory and mechanism design. Born on March 29, 1951, he has significantly influenced economic theory, particularly in understanding how institutions can be designed to achieve desired outcomes in strategic situations. Myerson received the Nobel Prize in Economic Sciences in 2007, sharing it with Leonid Hurwicz and Eric Maskin for their work on mechanism design theory. This theory helps explain how to create systems or rules that lead to efficient outcomes, even when individuals act in their own self-interest.
