Framing effects on asset markets : an experimental analysis
Kirchler, Erich; Maciejovsky, Boris; Weber, Martin - 2001
In this paper we investigate four hypotheses which are inconsistent with expected utility theory, but may well be … explained by prospect theory. It deals with framing, the non-linearity of subjective probabilities, the disposition effect, and …) found little correspondence between different experimental risk elicitation methods. -- Prospect Theory ; Framing …

A state space model for Berlin house prices
Schulz, Rainer; Werwatz, Axel - 2001
How risky are investments in residential real estate? To answer this question, information is needed about the behavior of house prices. The hedonic methodology has become a standard approach for modelling the prices of heterogeneous assets. Although intuitively appealing, it is often criticized...

Default compensator, incomplete information, and the term structure of credit spreads
Giesecke, Kay - 2001
We provide a framework for the analysis of term structures of credit spreads on corporate bonds in the presence of informational asymmetries. While bond investors observe default incidents, we suppose that they have incomplete information on the firm's assets and/or the threshold asset level at...

Correlated default with incomplete information
Giesecke, Kay - 2001
We propose a model of correlated multi-firm default with incomplete information. While public bond investors observe issuers' assets and defaults, we suppose that they are not informed about the threshold asset level at which a firm is liquidated. Bond investors form instead a prior on these...

Compensator-based simulation of correlated defaults
Giesecke, Kay - 2002
The market for derivatives with payoffs contingent on the credit quality of a number of reference entities has grown considerably over recent years. The risk analysis and valuation of such multi-name structures often relies on simulating the performance of the underlying credits. In this paper...

A class of Health-Jarrow-Morton models in which the unbiased expectations hypothesis holds
Riedel, Frank - 1997
The unbiased expectations hypothesis states that forward rates are unbiased estimates for future short rates. Cox, Ingersoll and Ross [1] conjectured that this hypothesis should be inconsistent with the absence of arbitrage possibilities. Using the framework of Heath, Jarrow and Morton [4] we...

Optional decomposition and lagrange multipliers
Föllmer, Hans; Kabanov, Jurij M. - 1997
Let Q be the set of equivalent martingale measures for a given process S, and let X be a process which is a local supermartingale with respect to any measure in Q. The optional decomposition theorem for X states that there exists a predictable integrand ф such that the difference X−ф•S is...

Quantile hedging
Föllmer, Hans; Leukert, Peter - 1998
In a complete financial market every contingent claim can be hedged perfectly. In an incomplete market it is possible to stay on the safe side by superhedging. But such strategies may require a large amount of initial capital. Here we study the question what an investor can do who is unwilling...

Efficient hedging : cost versus shortfall risk
Föllmer, Hans; Leukert, Peter - 1999
An investor faced with a contingent claim may eliminate risk by (super-)hedging in a financial market. As this is often quite expensive, we study partial hedges, which require less capital and reduce the risk. In a previous paper we determined quantile hedges which succeed with maximal...
