In distortion-based analysis of social choice rules over metric spaces, voters and candidates
are jointly embedded in a metric space. Voters rank candidates by non-decreasing distance …

We examine information structure design, also called" persuasion" or" signaling," in the
presence of a constraint on the amount of communication. We focus on the fundamental …

We study auctions with severe bounds on the communication allowed: each bidder may only
transmit t bits of information to the auctioneer. We consider both welfare-and profit …

We consider mechanism design in which message sets are restricted owing to
communication costs, preventing full revelation of information. A principal contracts with …

Recent technology advances have enabled firms to flexibly process and analyze
sophisticated employee performance data at a reduced and yet significant cost. We develop …

In a multi-party machine learning system, different parties cooperate on optimizing towards
better models by sharing data in a privacy-preserving way. A major challenge in learning is …

We study auctions with severe bounds on the communication allowed: each bidder may only
transmit t bits of information to the auctioneer. We consider both welfare-maximizing and …

We study auctions under restricted communication. Agents have valuations distributed over
an interval but can only report one of a finite number of messages. We provide necessary …

A fundamental result in mechanism design theory, the so-called revelation principle, asserts
that for many questions concerning the existence of mechanisms with a given outcome one …

A key trend in (electronic) commerce is a demand for higher levels of expressiveness in the
mechanisms that mediate interactions. We develop a theory that ties the expressiveness of …
