Designing Simple Mechanisms
现实世界的机制是否简单很重要，如果参与者看不出机制是激励相容的，他们可能拒绝参与或做出破坏机制的行为。本文解释了三种形式化“简单”含义的方法，并提出了未来研究方向。
It matters whether real-world mechanisms are simple. If participants cannot see that a mechanism is incentive-compatible, they may refuse to participate or may behave in ways that undermine the mechanism. There are several ways to formalize what it means for a mechanism to be “simple.” This essay explains three of them, and suggests directions for future research.
