In this paper, we derive an equilibrium in which some investors buy call/put options on the market portfolio while others sell them. Since investors are assumed to have similar risk-averse preferences, the demand for these contracts is not explained by differences in the shape of utility...

How do policy and performance of firms change with variations in the stakeholder approach? We compare foundation owned firms (FoFs) and family firms, with and without codetermination. As foundations have no owners, the impact on corporate governance of residual claimants might be weaker and the...

This paper contributes to the economics of financial institutions risk management by exploring how loan securitization affects their default risk, their systematic risk, and their stock prices. In a typical CDO transaction a bank retains through a first loss piece a very high proportion of the...

This paper compares the attractiveness of floor trading and anonymous electronic trading systems. It is argued that in times of low information intensity, the insight into the order books of the electronic trading system provides more valuable information than floor trading; but in times of high...

A recent trend in the German asset-backed securities (ABS) market is the securitization of subordinated loans and profit participation agreements (PPAs) granted to medium-sized enterprises (MEs). This paper provides an overview of this growing market and analyzes the benefits of such...

This paper analyzes the governance and performance of firms which, according to simplistic agency theory, should not be viable. These firms are fully or partially owned by a foundation which itself is not owned by natural or legal persons. Therefore, residual claimholders have restricted or no...

Portfolio choice and the implied asset pricing are usually derived assuming maximization of expected utility. In this paper, they are derived from risk-value models which generalize the Markowitz-model. We use a behaviorally based risk measure with an endogenous or exogenous benchmark. A richer...

Investors choosing a portfolio strategy, in order to secure a pension at a future date, are faced with many uncertainties. One major uncertainty, is the amount by which their pension fund will be supplemented by personal savings from a variety of sources such as future labor income, bequests, or...

This paper empirically investigates the tranching of European securitizations of corporate loans and bonds. Loans or bonds are pooled together in a portfolio which then is sliced into a First Loss Position and rated bond tranches. The originator tranches so as to minimize the sum of the credit...

HARA-utility investors allocate their money to a risk-free fund and to a risky fund (two fund separation). The paper shows that under weak conditions, the risky fund can be approximated by the risky fund derived from exponential utility, without material effects on the certainty equivalent of...
