Marrying Pricing and Advertising with LLMs

We study a sequential pricing problem in which a seller jointly posts a price and an advertisement generated by a large language model (LLM).

Key points

  • The seller aims to maximize revenue under an unknown product demand that depends on both decisions, while observing only whether each offer leads to a purchase.
  • We propose an online actor-critic algorithm that combines low-rank adaptation (LoRA) of a pretrained LLM with a demand model fitted to available data.
  • At each round, the actor generates an advertisement, and the critic estimates purchase probabilities to guide price selection.
  • To evaluate our approach, we develop an evaluation framework with three synthetic demand models and a demand simulator built from real-world marketplace data.
