Thomas Schelling was awarded the 2005 Nobel Prize in Economics for his work enhancing understanding of conflict and cooperation through game theory analysis. Some of his most important works included The Strategy of Conflict (1960) and Micromotives and Macrobehavior (1978). Schelling made seminal contributions to strategic studies, game theory, behavioral economics, and experimental economics. He introduced influential concepts like coordination problems, focal points, negotiation and uncertain retaliation. Despite calling himself an "errant economist", Schelling was hugely influential and a pathfinder in multiple social sciences.
