Advanced Topic 37 of 51 Emerging & Frontier Topics

Mechanism Design

Designing rules so self-interested agents produce good outcomes.

How it works

The inverse of game theory: design rules so rational agents reveal truthful information and reach good outcomes, as in Vickrey (second-price) auctions where bidding true value is optimal.

Where it is used

Ad auctions, matching markets.

Common pitfall

Incentives can be gamed in unexpected ways.

Where it fits in the course

Mechanism Design is topic 37 of 51 in Emerging & Frontier Topics, rated Advanced. It follows Game Theory. The next topic is Computational Geometry.
