We consider a network that intermediates traffic between free content providers and consumers. While consumers do not know the traffic cost when deciding on consumption, a content provider knows his cost but may not control the consumption. We study how pricing consumers' and content providers'...

Payment card associations offer both debit and credit cards and, until recently, engaged in a tie-in on the merchant side through the so-called honour-all-cards (HAC) rule. The HAC rule came under attack on the grounds that the credit and debit card markets are separate markets and that the...

Due to technological convergence, multiple infrastructures can now offer broadband or triple-play services, while the existing access regulation is based on a single essential network. We show that continued asymmetric access regulation of one network does not control sufficiently for market...

In February 2008, British Telecommunications (BT) introduced automatically renewing, or ‘rollover’, contracts into the UK market for fixed-voice telephone service. These contracts included a 12-month Minimum Contract Period (MCP) with associated Early Termination Charges (ETCs). Unless...

There has been a wide-spread belief that elections with a wide franchise following removal of an oppressive dictator lead to establishment of a government that is not vulnerable to mass protest. At the same time, most of the post-World War II non-constitutional exits of recently-installed...

We investigate cooperative investment for the deployment of a new infrastructure, and how it interacts with access obligations and demand uncertainty. Co-investment increases total coverage only if service differentiation and/or cost savings from joint investment, in particular due to high...

We study substitution from fixed-line to mobile voice access, and the role of various complementarities that may influence this process.We use rich survey data on 160,363 households from 27 EU countries during 2005-2012. We estimate a discrete choice model where households may choose one or both...

We analyze competition between vertically integrated infrastructure operators that provide access in different geographical areas. A regulator may impose a uniform access price, set local access rates, or deregulate access locally. We analyze the impact of these alternative regulatory regimes on...

We propose a two-sided model with two competing Internet platforms, and a continuum of Content Providers (CPs). We study the effect of a net neutrality regulation on capacity investments in the market for Internet access, and on innovation in the market for content. Under the alternative...

We use a classroom game, the ‘Wallet Game’, to show that in standard ascending, i.e. English, auctions of close-to-common-values objects, even slight asymmetries between bidders can have very large effects on prices. Examples of small asymmetries are a small value advantage for one bidder or...
