This paper provides an axiomatic approach to the problem of measuring the informationcontained in opportunity sets. In many choice situations, the items that can be selectedfrom an opportunity set (the objects of choice) do not coincide with the consequencesthey induce (the objects a...

We generalize the classical concept of a certainty equivalent to a model where an investor can trade on a capital market with several future trading dates.We show that if a riskless asset is traded and the investor has a CARA utility then our generalized certainty equivalent can be evaluated...

This paper first provides a simple but very general framework for credit portfolio modellingwhich is based on the distinction between systematic and unsystematic risk. Unsystematicor borrower-specific risk vanishes through diversification in a very large, infinitelyfine-grained portfolio. The...

This paper delevops a tools to analyse the ordering of concordance of random vectors.

This papfer deals with distributional free inference to test for positive quadrant dependence, i.e. for the probability that two variables are simultaneously small (or large) being at least as great as it would be were they dependent.

Vor dem Hintergrund allgemeiner Bedingungen der Anreizkompatibilität wird für verschiedenen Kapitalmarktmodelle untersucht, ob zwischen den Anteilseignern eines Unternehmens Einmütigkeit besteht und, wenn ja, mit welchem Unternehmensziel der finanzielle Nutzen der Anteilseigner maximiert...

Portfolio choice and the implied asset pricing are usually derived assumingmaximization of expected utility. In this Paper, they are derived from risk-value models that generalize the Markowitz-model. We use a behaviourally-based risk measure with an endogenous or exogenous benchmark...

In this paper the authors experimentally test overconfidence in investment decisions by ordering participants the possibility to substitute their own for alternative investment choices.

The authors demonstrates that, in contrast to optimistic investors, pessimistic investors may strictly prefer investing in an illiquid asset toinvesting in a liquid asset.

This paper investigates the robustness of hindsight bias in experimental asset markets, the time invariance of the different experimental risk elicitation methods of certainty equivalents and binary lottery choices, and their correspondence.
