Learning to Bid in Discriminatory Auctions with Budget Constraints

arXiv:2606.29252v1 Announce Type: new Abstract: We study repeated bidding in multi-unit discriminatory (pay-as-bid) auctions for a single bidder with per-round utility equal to value minus $\alpha$ times payment, where $\alpha\in[0,1]$ is a cost-of-capital parameter. The bidder aims to maximize cumulative utility over $T$ rounds subject to a total budget $B$. The problem is challenging even without budgets: the action space is exponential in $M$, the maximum demand of the bidder and the valuation vector (context) varies over time. Exploiting a decomposition of utility across units, we develop

Why this matters
Why now

The increasing complexity and scale of online auctions, particularly in programmatic advertising and cloud resource allocation, necessitate more sophisticated automated bidding strategies.

Why it’s important

Optimized bidding strategies with budget constraints are crucial for businesses to maximize returns on their investments in competitive digital markets and for efficient resource allocation in AI-driven economies.

What changes

This research provides a theoretical and algorithmic framework for AI agents to participate more effectively in multi-unit discriminatory auctions, particularly in scenarios with financial constraints.

Winners
  • · Companies with significant digital advertising spend
  • · Cloud service providers (optimizing resource allocation)
  • · AI/ML researchers in game theory
  • · Ad-tech platforms
Losers
  • · Inefficient bidders without advanced AI strategies
  • · Auction platforms with easily exploitable mechanisms
Second-order effects
Direct

Improved bidding efficiency for automated agents in complex auctions.

Second

Increased competition and potentially higher prices in programmatic ad markets as agents become more sophisticated.

Third

The development of more complex, dynamic auction mechanisms designed to counter advanced AI bidding strategies.
