In this paper we present empirical evidence linking mobile network outages to violence against women. Using high-frequency data from Brazil, we show that the disruption caused by the mandatory 9-digit dialing transition for cell phone numbers had unintended consequences, increasing...

Online reading platforms offer a by-chapter purchase method and implement a novel in-chapter online review function to mitigate consumer uncertainty regarding the true quality of e-books. In this study, we seek to uncover how such intervention affects consumer purchase decisions. In particular,...

Telecommunication sector faces to parallel investments into both fiber and 5G, however due to monetization challenges, return on investments often lag behind normal profit expectations. Co-investment, like mobile network sharing can promote cost efficiency, however cooperation raises regulatory...

Radio spectrum is fundamental to the operation of wireless communications services. In order to allocate radio spectrum for different services, spectrum is regulated via national laws, coordinated by an international body, the International Telecommunications Union (ITU). For the most part,...

We evaluate the impact of competition on investments in Europe’s mobile communications market during the 2011-2021 period. There are stark and sustained differences in market outcomes between three- and four-player markets in Europe, and economic theory suggests these could be partly explained...

This paper examines the effects of spectrum auctions on mobile market competition. A simple theoretical model suggests that bigger incumbents will acquire more spectrum in auction to preempt after-market competitors. We use novel data from European 4G spectrum auctions to present suggestive...

We present novel evidence from a large panel of UK consumers who receive personalized reminders from a specialist price-comparison website about the precise amount they could save by switching to their best-suited alternative mobile telephony plan. We document three phenomena. First, even...

In POLICY BULLETIN NO. 54, I compared fixed broadband speeds across thousands of U.S. and foreign cities. My analysis revealed that average download speeds for fixed broadband are typically faster in the United States and often materially so, and U.S. upload speeds are comparable to other...

This chapter analyzes structural changes arising from both economy‐wide and life-course- long applications of mobile communication technology. These changes trickle through all sectors of society, including the domestic sphere, which arguably has been most profoundly affected by it. We discuss...
