Modeling Correlation in Competitive Revenue Management
Refik Güllü
Industrial Engineering Department, Boğaziçi University

Abstract
We model a competitive revenue management game where two firms choose their prices to maximize their revenues. Respective valuations of the firms by consumers (consumers' willingness-to-pay) are correlated random variables. A consumer who is willing to pay a higher than average price to a product or service may be willing to pay a lower or higher than average price for its competitor. We discuss structural properties of the problem, show the existence of the unique price equilibrium, and present interesting comparative statics of the game for the case where the willingness-to-pay random variables take a particular bivariate exponential distribution.
Joint work with Engin Yıldız and Taner Bilgiç.
