Position: The Pre/Post-Training Boundary Should Govern IP in Industry-Academia ML Collaborations
Dirk Bergemann, Soheil Ghili, Nitzan Mekel-Bobrov
Industry-academia ML collaborations routinely fail to launch -- not for scientific reasons, but because academics must publish while companies must protect models trained on propri…
Training Language Models for Bilateral Trade with Private Information
Dirk Bergemann, Soheil Ghili, Xinyang Hu +2
Bilateral bargaining under incomplete information provides a controlled testbed for evaluating large language model (LLM) agent capabilities. Bilateral trade demands individual rat…
Pay-Per-Crawl Pricing for AI: The LM-Tree Agent
Richard Archer, Soheil Ghili, Nima Haghpanah
As AI systems shift from directing users to content toward consuming it directly, publishers need a new revenue model: charging AI crawlers for content access. This model, called p…
Auctions Meet Bandits: An Empirical Analysis
Mohammad Rashid, Omid Rafieian, Soheil Ghili
Sponsored search positions are typically allocated through real-time auctions, where the outcomes depend on advertisers' quality-adjusted bids - the product of their bids and quali…
Second-degree Price Discrimination: Theoretical Analysis, Experiment Design, and Empirical Estimation
Soheil Ghili, K. Sudhir, Nitish Jain +1
We build on theoretical results from the mechanism design literature to analyze empirical models of second-degree price discrimination (2PD). We show that for a random-coefficients…
An Empirical Analysis of Optimal Nonlinear Pricing in Business-to-Business Markets
Soheil Ghili, Russ Yoon
In continuous-choice settings, consumers decide not only on whether to purchase a product, but also on how much to purchase. Thus, firms optimize a full price schedule rather than…
Spatial Distribution of Supply and the Role of Market Thickness: Theory and Evidence from Ride Sharing
Soheil Ghili, Vineet Kumar
This paper studies the effects of economies of density in transportation markets, focusing on ridesharing. Our theoretical model predicts that (i) economies of density skew the sup…
A Characterization for Optimal Bundling of Products with Non-Additive Values
Soheil Ghili
This paper studies optimal bundling of products with non-additive values. Under monotonic preferences and single-peaked profits, I show a monopolist finds pure bundling optimal if…
Eliminating Latent Discrimination: Train Then Mask
Soheil Ghili, Ehsan Kazemi, Amin Karbasi
How can we control for latent discrimination in predictive models? How can we provably remove it? Such questions are at the heart of algorithmic fairness and its impacts on society…
