We propose a new approach to the normative analysis of public-good provision. In addition to individual incentive compatibility, we impose conditions of robust implementability and coalition proofness. Under these additional conditions, participants' contributions can only depend on the level of...

The paper discusses the reform of capital regulation of banks in the wake of the financial crisis of 2007/2009. Whereas the Basel Committee on Banking Supervision seems to go for marginal changes here and there, the paper calls for a thorough overhaul, moving away from risk calibration and...

We propose a new approach to the normative analysis of public-good provision in a large economy. Our analysis is based on a mechanism design approach that involves a requirement of coalition-proofness, as well as a requirement of robustness, so that the mechanism must not depend on specific...

For an incomplete-information model of public-good provision with interim participation constraints, we show that efficient outcomes can be approximated, with approximately full surplus extraction, when there are many agents and each agent is informationally small. The result holds even if...

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...

The paper develops a version of Pontryagin's maximum principle for optimal control problems with monotonicity constraints on control variables. Whereas the literature handles such constraints by imposing an assumption of piecewise smoothness on the control variable and treating the slope of this...

McAfee and Reny (1992) have given a necessary and sufficient condition for full surplus extraction in naive type spaces with a continuum of payoff types. We generalize their characterization to arbitrary abstract type spaces and to the universal type space and show that in each setting, full...

The first part of the paper considers the effects of pre-empting a resolution procedure for a troubled financial institution by a precautionary recapitalization as specified in Article 32 (4) (d) of the Bank Recovery and Resolution Directive (BRRD). Benefits are seen for the maintenance of...

For a countable product of complete separable metric spaces with a topology induced by a uniform metric, the set of Borel probability measures coincides with the set of completions of probability measures on the product σ-algebra. Whereas the product space with the uniform metric is...

This lecture discusses the 2010 crisis of the European Monetary Union and draws some lessons for reform. Crisis resolution has been difficult because the sovereign debt crisis of countries like Greece and Portugal has come together with real-estate and banking crises in countries like Ireland...
