Our results establish the first polynomial convergence rates on the revenue generated by no-swap regret bidders in first-price auctions. For instance, if bidders admit the optimal swap regret of $\\mathcal{O}(\\sqrt{k T})$, then the time-averaged revenue is at least $v_2 - Θ(1/k) - Θ(ε)$ after $\\mathcal{O}(k^5/ε^2)$ rounds.","short_abstract":"We study the revenue of approximate correlated equilibrium in discrete first price auctions - the set of allowable bids is $\\mathcal{B} = \\{0, 1/k, \\dots, 1 - 1/k, 1\\}$ for some $k \\in \\mathbb{N}$.
