Competitors privately sharing price intentions is universally prohibited under antitrust/competition law. In contrast, there is no common well-accepted treatment of competitors privately sharing prices. This paper shows that firms sharing prices leads to higher prices. Based on this theory of harm, it is argued that there should be a per se prohibition on sharing prices.
