Overview & Synopsis

Given an incentive-compatible mechanism for a single agent on a restricted domain of valuations, we consider its incentive-compatible extensions to the entire valuation space. We identify two extreme extensions: the "keep-the-menu" extension, which minimizes buyer payoffs and maximizes canonical prices pointwise, and the "keep-the-pricing" extension, which maximizes buyer payoffs and minimizes canonical prices pointwise.
