Free in-network pricing as an entry-deterrence strategy

This paper analyzes the entry-deterring power of free in-network pricing with multiple incumbents. Free in-network pricing may deter entry since it creates network externality that intensifies competition. One may expect that a particular entry-deterrent strategy adopted by all incumbents would have more entry-deterring power than when it is adopted by some incumbents only. However, we show that when free-in network plan has entry-deterrence power with two incumbent firms, sometimes one incumbent offering free in-network plan may have more entry deterrence power than both firms offering free in-network plans. In other words, we find that an asymmetric adoption of entry-deterrence strategies by the incumbent firms may be the best for entry deterrence. This result highlights the importance of the strategic choice of the pricing plan as a function of not only the likelihood/cost of entry but also of the plan choices of other firms, and may partially explain the asymmetric strategies used by competing firms.
