Mechanism Design: How to Achieve Social Goals

Eric Maskin

Nobel Prize in Economics Papers Series： 机制设计：如何实现社会目标 The lecture, Mechanism Design: How to Achieve Social Goals," delves into mechanism design theory, describing it as an "economic engineering" capable of achieving specific social goals. Contrary to traditional economics' prediction of existing institutional outcomes, this theory first sets an ideal goal, then works backward to derive and construct game rules that achieve that goal. Eric Maskin demonstrates, through examples, how to design incentive-compatible mechanisms in situations of information asymmetry, enabling individuals to pursue their own interests while simultaneously achieving collective optimality. The author highlights Nash's implementation theory, pointing out that monotonicity and the absence of veto power are the core logical conditions ensuring the realization of social choice rules. Furthermore, the lecture reviews the development of this discipline from early debates on planned economies to modern applications of game theory, emphasizing its unique value in addressing market failures.
