John C. Harsanyi

John C. Harsanyi was a Hungarian-American economist and Nobel laureate known for his work in game theory, particularly regarding how individuals make decisions in strategic situations. He introduced the concept of "incomplete information," which examines how players make decisions when they don't know all the details about others' preferences or actions. Harsanyi's insights laid the foundation for understanding economic and social interactions in a range of fields, including economics, political science, and psychology. His contributions have been crucial in analyzing competitive environments and negotiations, earning him recognition as a key figure in modern economic thought.
