Edelman, Benjamin, and Julian Wright. “Markets with Price Coherence.” Harvard Business School Working Paper, No. 15-061, January 2015. (Revised March 2015.) (Supplement to “Price Coherence and Excessive Intermediation.”)
In markets with price coherence, the purchase of a given good via an intermediary is constrained to occur at the same price as a purchase of that same good directly from the seller (or through another competing intermediary). We examine ten markets with price coherence, including their origin and outcomes as well as concerns and policy interventions.
