报告题目: Network Effect and Multi-Network Sellers' Dynamic Pricing: Evidence from the US Smartphone Market

摘要:The smartphone operating system (OS) network effect influences the dynamic pricing strategy of the multi-OS telecom carriers. I show that multi-OS sellers choose lower prices for larger OSs, which is the opposite of single-OS sellers’ strategy. Using product-level data in the US, I estimate a structural model of consumer demand and carriers' dynamic pricing game for two-year contract smartphones. With new methods, I solve the dynamic game involving asymmetric multi-product carriers and continuous state variables. The estimated network effect is significantly positive. Counterfactual analysis shows that, if the carriers were single-OS sellers, the OS market would be less concentrated and consumer surplus would decrease.
