Many technology studies have conceptualized transitions between technological generations as a series of S-curve performance improvements over time. Surprisingly, the interregnum between successive technological generations has received little attention. To understand what happens in the...

We consider some two dynamic models of entry in mobile telephony, with and without strategic pricing, and taking into account market penetration at entry, locked-in consumers and tariff-mediated network externalities. We show that on/off-net differentials may reduce the possibility of entry if...

This paper questions whether competition can replace sector-specific regulation of mobile telecommunications. We show that the monopolistic outcome may prevail independently of market concentration when access prices are determined in bilateral negotiations. A lighthanded regulatory policy can...

The U.S. spectrum licenses cover geographically distinct areas and are often complementary to each other. A bidder seeking to acquire multiple licenses is then exposed to risks of winning only isolated patches. To allocate licenses more efficiently, the Federal Communications Commission allowed...

Firms considering to enter into online markets face significant demand uncertainty and consumer search costs, with consumers most likely finding previously successful products in the market. This leads to a trade-off for potential entrants. Consider the appearance of a new very popular product...

This paper studies the impact of platform-owner entry threat on complementors in platform-based markets. We examine how app developers on the Android mobile platform adjust innovation efforts (rate and direction) and value-capture strategies in response to the threat of Google's entry into their...

I study how firms actually compete in nonlinear tariffs by analyzing whether the incumbent and entrant's decisions to offer a given number of tariff options are interrelated. The goal is to shed some light on those dynamic and strategic aspects of tariff menus that are currently ignored by...

This paper develops an empirical framework to analyze consumer's dynamic switching decision in the cellular service industry. It first incorporates the sequential problem of quantity, plan and firm subscription choice in the presence of switching costs into a dynamic structural model, which...

The US mobile phone industry has dramatically consolidated through mergers. We investigate whether a merger increases the performance of a combined carrier over the sum of its constituent parts. We first directly compare the quantities of post-merger carriers to those of their pre-merger...

This paper proposes to incorporate product customization in the Maskin and Riley (1984) nonlinear pricing model in order to capture major features of mobile service data. In particular, consumers are characterized by a two-dimensional type. One dimension is observed by the provider and...
