TALK: Constantinos Daskalakis: Mechanism Design via Optimal Transport
Abstract: I will present an optimization framework based on optimal transport theory, characterizing the structure
of revenue-optimal mechanisms in single-bidder multi-item settings. Our framework provides closed-form descriptions
of mechanisms, generalizes Myerson's celebrated single-item auction, and exhibits simple settings with very rich structure
in their optimal mechanism. Our framework improves previous partial results, by establishing a strong duality theorem
between optimal mechanism design and optimal transportation, and is enabled by an extension of the Monge-Kantorovich
duality that accommodates convexity constraints.
The talk is based on work with Alan Deckelbaum and Christos Tzamos
