A fully unbundled, regulated network fi?rm of unknown efficiency level can undertake unobservable effort to increase the likelihood of low downstream prices, e.g., by facilitating downstream competition. To incentivize such effort, the regulator can use an incentive scheme paying transfers to...

The market for law professors fulfils the conditions for a hog cycle: in the short run, supply cannot be extended or limited; future law professors must be hired soon after they first present themselves, or leave the market; demand is inelastic. Using a comprehensive German dataset, we show that...

We examine the pervasive view that “equity is expensive,” which leads to claims that high capital requirements are costly and would affect credit markets adversely. We find that arguments made to support this view are either fallacious, irrelevant, or very weak. For example, the return on...

We examine the pervasive view that “equity is expensive,” which leads to claims that high capital requirements are costly for society and would affect credit markets adversely. We find that arguments made to support this view are fallacious, irrelevant to the policy debate by confusing...

Competition between parallel infrastructures incorporates opposing welfare effects. The gain from reduced deadweight loss might be outweighed by the inefficient duplication of an existing infrastructure. Using data from broadband internet access for Western Europe 2000-2004, this paper...

Corporate actors differ from individuals in one important respect: technically, it may be possible to observe the formation of the corporate will from outside, and to impact on its formation. This feature can be exploited by regulators. One technology is inducing corporate actors to hire an...

From the angle of competition policy, Voice over IP looks like a panacea. It not only brings better service, but it also increases competitive pressure on former telecommunications monopolists. This paper points to the largely overlooked downside. In a pure world of Internet telephony, there...

The paper discusses the respective roles of competition policy and sector-specific regulation for industries such as telecommunications, electricity, and gas, in which network infrastructures that are natural monopolies serve as essential facilities for anybody who wants to provide services in...

Traditionally, there have been two separate telecommunications networks, one based on switches, the other based on routers. The switched network basically carried voice. The packet switched network basically carried data. Now voice is about to go packet switched too. Ultimately, both networks...
