An anonymous social choice function for a large atomless population maps cross-section distributions of preferences into outcomes. Because any one individual is too insignificant to affect these distributions, every anonymous social choice function is individually strategy- proof. However, not...

The paper studies efficient public-good provision in a model with private values whose distribution depends on a macro shock; conditionally on this shock, values are independent and identically distributed. A generalization of the Bayesian mechanism of d'Aspremont and Gérard-Varet is shown to...

The paper provides theoretical foundations for models of strategic interdependence under uncertainty that have a continuum of agents and a decomposition of uncertainty into a macro component and an agent‐specific micro component, with a law of large numbers for the latter. This macro-micro...

According to Homburg's (2014) comment on Kim and Lee (1997), an ad-valorem property tax on land cannot cause dynamic ineffi ciency of equilibrium allocations in an overlapping-generations model unless the tax is "confiscatory", i.e., equal to or greater than land rents. With such a tax, Homburg...

The paper contains comments made on the Financial Stability Board's (FSB) Consultation Report concerning the success of regulatory reforms since the global financial crisis of 2007-2009. According to these comments, the FSB’s assessment of the role of equity is too narrow, being phrased in...

Kolmogorov's extension theorem provides a natural mapping from the space of coherent hierarchies of an agent's first-order, second- order, etc. beliefs to the space of probability measures over the exogenous parameters and the other agents' belief hierarchies. Mertens and Zamir (1985) showed...

Der Text beruht auf einer am 9. Mai 2017 vor dem Bundesverfassungsgericht abgegebenen Stellungnahme in der mündlichen Verhandlung zu einem Verfahren über den Umfang der Verpflichtung der Bundesregierung zur Information des Parlaments (Az. 2BvE 2/11). Das Gericht hatte um Auskünfte zur...

The paper gives conditions for dynamic inefficiency of laissez-faire allocations in an overlapping-generations model with safe and risky assets. If the rate of population growth is certain, the conditions given depend only on how the rate of return on safe assets compares to the growth rate. If...

The paper discusses the problem of valuation in bank resolution. In an overview over the most relevant principles of valuation theory, the paper notes the difficulties inherent in valuing risks and illiquidity in holding non-traded assets. Subsequently, the paper briefly reviews the resolution...
