- Abstract: We study an online contextual dynamic pricing problem, where customers decide
whether to purchase a product based on its features and price. We introduce a
novel approach to modeling a customer's expected demand by incorporating
feature-based price elasticity, which can be equivalently represented as a
valuation with heteroscedastic noise. To solve the problem, we propose a
computationally efficient algorithm called "Pricing with Perturbation (PwP)",
which enjoys an $O(\sqrt{dT\log T})$ regret while allowing arbitrary
adversarial input context sequences. We also prove a matching lower bound at
$\Omega(\sqrt{dT})$ to show the optimality regarding $d$ and $T$ (up to $\log
T$ factors). Our results shed light on the relationship between contextual
elasticity and heteroscedastic valuation, providing insights for effective and
practical pricing strategies.

We address the problem of dynamically pricing complementary items that are sequentially displayed to customers.
Coherent pricing policies for complementary items are essential because optimizing the pricing of each item individually is ineffective.
We empirically evaluate our approach using synthetic settings randomly generated from real-world data, and compare its performance in terms of constraints violation and regret.

We study the contextual dynamic pricing problem with strategic buyers.

We propose a strategic dynamic pricing policy that incorporates the buyers' strategic behavior into the online learning to maximize the seller's cumulative revenue.

We consider a novel dynamic pricing and learning setting where in addition to setting prices of products, the seller also ex-ante commits to 'advertising schemes'
We use the popular Bayesian persuasion framework to model the effect of these signals on the buyers' valuation and purchase responses.
We design an online algorithm that can use past purchase responses to adaptively learn the optimal pricing and advertising strategy.

We measure the performance of a dynamic pricing policy via regret, which is the expected revenue loss compared to a clairvoyant that knows the sequence of model parameters in advance.
Our regret analysis results not only demonstrate optimality of the proposed policy but also show that for policy planning it is essential to incorporate available structural information.
