DESCRIPTION:Titolo: The bilateral trade problem from an online learning per
 spective: partial feedback and needles in the haystack Bilateral trade\, a
  fundamental topic in economics\, models the problem of intermediating bet
 ween two strategic agents\, a seller and a buyer\, willing to trade a good
  for which they hold private valuations. We cast the bilateral trade probl
 em in a regret minimization framework over T rounds of seller/buyer intera
 ctions\, with no prior knowledge on their private valuations. Our main con
 tribution is a nearly complete characterization of the regret regimes for 
 fixed-price mechanisms with different feedback models and private valuatio
 ns\, using as a benchmark the best fixed-price in hindsight. The talk is b
 ased on the following papers:- Nicolò Cesa-Bianchi\, Tommaso Cesari\, Robe

 e Against a Smoothed Adversary'\, preprint on the arXiv\, 2023- Nicolò Ces
