Randomized Truthful Auctions with Learning Agents
Gagan Aggarwal, Anupam Gupta, Andres Perlroth +1
We study a setting where agents use no-regret learning algorithms to participate in repeated auctions. \citet{kolumbus2022auctions} showed, rather surprisingly, that when bidders p…
Auto-bidding and Auctions in Online Advertising: A Survey
Gagan Aggarwal, Ashwinkumar Badanidiyuru, Santiago R. Balseiro +23
In this survey, we summarize recent developments in research fueled by the growing adoption of automated bidding strategies in online advertising. We explore the challenges and opp…
Platform Competition in the Autobidding World
Gagan Aggarwal, Andres Perlroth, Ariel Schvartzman +1
We study the problem of auction design for advertising platforms that face strategic advertisers who are bidding across platforms. Each advertiser's goal is to maximize their total…
Ads in Conversations
Martino Banchio, Aranyak Mehta, Andres Perlroth
We study the optimal placement of advertisements for interactive platforms like conversational AI assistants. Importantly, conversations add a feature absent in canonical search ma…
Multi-Channel Auction Design in the Autobidding World
Gagan Aggarwal, Andres Perlroth, Junyao Zhao
Over the past few years, more and more Internet advertisers have started using automated bidding for optimizing their advertising campaigns. Such advertisers have an optimization g…
Incentive Compatibility in the Auto-bidding World
Yeganeh Alimohammadi, Aranyak Mehta, Andres Perlroth
Auto-bidding has recently become a popular feature in ad auctions. This feature enables advertisers to simply provide high-level constraints and goals to an automated agent, which…

Advertisers in online ad auctions are increasingly using auto-bidding mechanisms to bid into auctions instead of directly bidding their value manually. One prominent auto-bidding f…
A Characterization of the n-th Degree Bounded Stochastic Dominance
Bar Light, Andres Perlroth
We provide a novel characterization of the -th degree bounded stochastic dominance (BSD) order, linking it to the risk tolerance of decision-makers and providing a decision-theo…
Efficiency of non-truthful auctions under auto-bidding

We study the mechanism design problem of selling items to unit-demand buyers with private valuations for the items. A buyer either participates directly in the auction or is re…
The Family of Alpha,[a,b] Stochastic Orders: Risk vs. Expected Value
Bar Light, Andres Perlroth
In this paper we provide a novel family of stochastic orders that generalizes second order stochastic dominance, which we call the -concave stochastic orders. These stocha…
