We study repeated bilateral trade when the valuations of the sellers and the buyers are contextual. More precisely, the agents' valuations are given by the inner product of a conte…
Anonymous Contracts
Johannes Brustle, Paul Duetting, Stefano Leonardi +2
We study a multi-agent contracting problem where agents exert costly effort to achieve individually observable binary outcomes. While the principal can theoretically extract the fu…
Contract Design Beyond Hidden-Actions
Tomer Ezra, Stefano Leonardi, Matteo Russo
In the classical principal-agent hidden-action contract model, a principal delegates the execution of a costly task to an agent. In order to complete the task, the agent chooses an…
Multicalibration Yields Better Matchings
Riccardo Colini Baldeschi, Simone Di Gregorio, Simone Fioravanti +9
Consider the problem of finding the best matching in a weighted graph where we only have access to predictions of the actual stochastic weights, based on an underlying context. If…
Online Learning in the Random Order Model
Martino Bernasconi, Andrea Celli, Riccardo Colini-Baldeschi +3
In the random-order model for online learning, the sequence of losses is chosen upfront by an adversary and presented to the learner after a random permutation. Any random-order in…
