The Effect of Market Structure on Cellular Technology Adoption and Pricing
研究了1996年至1998年间移动通信行业市场结构变化如何影响企业的数字技术采用和套餐定价策略，发现市场进入促使企业提供更多样化的套餐并降低价格，尤其对高价值用户更有利。
We examine how structural changes in the mobile telecommunications industry between 1996, when local markets were duopolies, and 1998, when varying degrees of regulated entry had occurred, affected firms' product offerings and nonlinear pricing strategies. We relate firms' digital technology adoption and the characteristics of their calling plan menus to the amount of entry in local markets. We find that entry induces firms to offer larger menus with more evenly spread plans, both directly and by accelerating the introduction of digital menus with such features. Prices decline with entry, in particular for high-valuation consumers who benefit from steeper quantity discounts.
