Matching “Versus” Mechanism Design
Matching “Versus” Mechanism Design
ACM SIGecom Exchanges, (2012): 11, no. 2, 4-15. [PDF]Abstract
In a typical mechanism design paper the goal is to find a mechanism that maximizes the designer’s objective (e.g., social welfare) subject to technology and incentive constraints. In a typical applied matching paper, by contrast, the goal is to find a mechanism that satisfies various “good properties” (e.g., efficiency and fairness). This essay discusses the relationship and tradeoffs between these two approaches. An introductory example, school choice, represents a simple win for the good properties approach. The main example, course allocation, paints a more complicated picture.
