A Profit-Maximizing Data Marketplace with Differentially Private Federated Learning under Price Competition
Summary: DPFL-based data marketplace with price-taking and price-setting owners, framed as a three-stage Stackelberg game to maximize requester profit under differential privacy. Convex with a unique SPNE; iterative algorithms; experiments show price competition lowers prices and increases profitability versus price-taking-only baselines.
