We study the optimal adaptation to extreme climate events by the central government in a setup where events are dynamically uncertain and the government does not know the true probabilities of events. We analyze different policy decision rules minimizing expected welfare losses for sites with...

Environmental policy often has to be devised under informational constraints, like uncertainty and asymmetric information. We consider an environmental policy that aims at reducing the welfare losses caused by asymmetric information while being sufficiently simple for implementation. In this...

We consider an abstract setting of the differential r&d game, where participating firms are allowed for strategic behavior. We assume the information asymmetry across those firms and the government, which seeks to support newer technologies in a socially optimal manner. We develop a general...

Arbitrage pricing cannot be applied to commodity futures because the physicalcommodity does not represent a pure asset: Since consumption and processing of thecommodity can drive down inventories to zero, it is not always possible to construct areplicating portfolio for the futures contract, and...

This paper examines properties of mean-variance inefficient proxieswith respect to producing a linear relation between expected returnsand betas. The numerical results of a Monte Carlo simulation showthat in the CAPM slightly inefficient, positively weighted proxies causean almost perfect linear...

Die Pro-Kopf-Ausgaben der Schweizer Kantone und Gemeinden unterscheiden sich sehr deutlich: Währendbspw. der Kanton und die Gemeinden von AI im Jahr 2002 nur 7 530 CHF pro Einwohner aufwendeten,beliefen sich die Pro-Kopf-Ausgaben von Basel-Stadt auf über 18 600 CHF2. Die Finanzlage der...
