What is mechanism design theory?
Mechanism design theory is about creating rules for games, or 'mechanisms,' that achieve a desired outcome. Instead of analyzing how people behave given a set of rules, it starts with the desired outcome and works backward to design the rules. My core contribution was developing a formal framework, using game theory, to prove the existence and characterize the properties of such mechanisms, particularly concerning how to ensure participants have an incentive to be truthful about their private information.
