Mums Go Online: Is the Internet Changing the Demand for Health Care
We study the effect of Internet diffusion on childbirth procedures performed in England between 2000 and 2011. We show that broadband Internet access increased cesarean sections (C-sections): mothers living in areas with better Internet access are 2.5% more likely to obtain a C-section. The effect is driven by first-time mothers who are 6% more likely to obtain a C-section. The increased C-section rate is not accompanied by changes in health care…
Net Neutrality: A Fast Lane to Understanding the Trade-offs
The last decade has seen a strident public debate about the principle of "net neutrality." The economic literature has focused on two definitions of net neutrality. The most basic definition of net neutrality is to prohibit payments from content providers to internet service providers; this situation we refer to as a one-sided pricing model, in contrast with a two-sided pricing model in which such payments are permitted. Net neutrality may also b…
Evaluating a Decade of Mobile Termination Rate Regulation
We re-consider the impact that regulation of call termination on mobile phones has had on mobile customers’ bills. Using a large panel covering 27 countries, we find that the “waterbed” phenomenon, initially observed until early 2006, becomes insignificant on average over the 10-year period, 2002-2011. We argue that this is related to the changing nature of the industry, whereby mobile-to-mobile traffic now plays a much bigger role compared to fi…

Active and Passive Waste in Government Spending: Evidence from a Policy Experiment
We propose a distinction between active and passive waste as determinants of the cost of public services. Active waste entails utility for the public decision maker, whereas passive waste does not. We analyze purchases of standardized goods by Italian public bodies and exploit a policy experiment associated with a national procurement agency. We find that: (i) some public bodies pay systematically more than others for equivalent goods; (ii) diffe…
Network Competition and Entry Deterrence
We develop a model of logit demand that extends the traditional duopoly framework of network competition to a multi-firm industry. First, we show that incumbents establish the reciprocal access charge inefficiently below cost when they compete in prices but they behave efficiently if they compete in utilities. Secondly, we study how incumbents determine the industry-wide access charge under the threat of entry. We show that incumbents may accommo…
