Ordered Search in Differentiated Markets

  • Jidong Zhou

This note presents an ordered search model in which consumers search both for price and product fitness. We construct an equilibrium in which there is price dispersion and prices rise in the order of search. The top firms in consumer search process, though charge lower prices, earn higher profits due to their larger market shares.
