Reaching Collective Decisions in Voting Systems - Game Theory Perspective

Explore the game-theoretic perspective of collective decision-making in this lecture from the Simons Institute. Delve into voting protocols and their applications in socio-economic and technological systems. Examine how strategic behaviors impact voting mechanisms and learn about using computational complexity as a barrier. Analyze voting scenarios through the lens of game theory, considering strategic parties as players and stable outcomes as equilibria. Investigate natural iterative processes like best-response dynamics and their variants. Discover conditions for achieving convergence in these processes and understand their importance for system-wide stability. Learn about a framework that justifies restricted voting dynamics as boundedly rational decisions under uncertainty. Gain insights into the challenges and approaches of reaching collective decisions in complex systems.
