Ramsey-Boiteux prices and monopoly prices are frequently regarded as being similar. This might suggest that, in particular in network in- dustries with large fixed costs, sometimes monopoly pricing is close to the Ramsey-Boiteux second best and welfare superior to imperfectly regulated prices....

This paper discusses various theoretic concepts which play a role in assessing the public benefits of Target, the large value RTGS payment network operated by the Eurosystem. These concepts touch upon natural monopoly, network externalities, competition and contestability, as well as economies...

In some industries, monopoly is natural. One provider can serve the relevant demand cheaper than two or more firms. If the monopoly is not contestable, i.e. not controlled by a credible threat of entry, regulation is necessary. The essential facilities doctrine is one such regulatory tool. It...

A digressive tax such as a variable rate sales tax or a tax on price gives firms an incentive for expanding output. Thus, unlike unit and ad valorem taxes which amplify the harm from monopoly, a digressive tax lessens the harm. We analyse a tax on price with respect to efficiency and practical...

This paper studies the relation between Bayesian mechanism de- sign and the Ramsey-Boiteux approach to the provision and pricing of excludable public goods. For a large economy with private informa- tion about individual preferences, the two approaches are shown to be equivalent if and only if,...

The paper develops an integrated model of optimal nonlinear income taxation, public-goods provision and pricing in a large economy. With asymmetric information about labour productivities and publicgoods preferences, the multidimensional mechanism design problem becomes tractable by requiring...

This paper takes up the debate whether price-cap regulation of airports should take the form of single-till or dual-till regulation. The contribution is to model single- and dual-till regulation, evaluate their welfare implications, and compare them to Ramsey prices. We show that the single-till...

This paper studies the aggregate and distributional implications of introducing user fees for publicly provided excludable public goods into a model with consumption and income taxes. The setup is a neoclassical growth model where agents differ in earnings and second-best policy is chosen by a...

In der Literatur finden sich zahlreiche Abhandlungen zu der Frage, welche Besonderheiten bei internationalen, also grenzüberschreitenden Unternehmensakquisitionen auftreten und in welcher Weise diese im Zuge einer Grenzpreisermittlung zu berücksichtigen sind. Als im Wesentlichen zu würdigende...

A well-known principle of welfare economics states that an efficient resources allocation can be achieved in a competitive economy when market prices are in line with social marginal costs. When applied to the transport sector, this implies that the price of the various transport modes should be...
