This paper studies the design of mechanisms that are robust to misspecification. We introduce a novel notion robustness connects a variety disparate approaches and study its implications in wide class of mechanism problems. is quantifiable, allowing us to formalize answer comparative statics questions relating nature and degree misspecification to sharp predictions regarding features of f...
