Product Similarity and Cross-Price Elasticity

  • Sreya Kolay
  • Rajeev K. Tyagi


We use a spatial competition model to show how an increasing similarity between two products can monotonically increase, monotonically decrease, or have a non-monotonic effect on cross-price elasticity. We relate these results to prior research that links cross-price elasticity to product similarity, and the literature on market structure, merger analysis, and price discrimination.
