Dynamic decision structure and risk taking
Eichberger, Jürgen; Güth, Werner; Müller, Wieland - 1999
This paper investigates the behaviour in repeated decision situations. The experimental study shows that subjects show … low or no risk-aversion, but put very high value on the opportunity to sell the lottery in every stage of the decision … behaviour ; decision-making experiments …

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...

Coherent risk measures, valuation bounds, and (my,p)-portfolio optimization
Jaschke, Stefan R.; Küchler, Uwe - 1999
This paper presents a general theory that works out the relation between coherent risk measures, valuation bounds, and … theory presented seems to fill a gap between arbitrage valuation on the one hand and single agent utility maximization or … full-fledged equilibrium theory on the other hand. "Coherent" valuation bounds strike a balance in that the bounds can be …

Please, marry me! : an experimental study of risking a joint venture
Güth, Werner; Ivanova-Stenzel, Radosveta; Tjotta, Sigve - 1999
Empirical studies in family economics usually rely on questionnaires, statistical or panel data. Here we try to study experimentally some crucial aspects of engaging in a marriage. First the female partner can end the relationship or suggest one of the two forms of joint venture. Whereas a full...

Strategies, heuristics and the relevance of risk aversion in a dynamic decision problem

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...

On model based seasonal adjustment procedures
Breitung, Jörg - 1998
In this note the unobserved component approach underlying the software package SEATS is compared with the Beveridge-Nelson type of decomposition for seasonal time series. The main strength of the SEATS approach lies in the appealing model formulation and the careful specification and adjustment...

The monetary model of the exchange rate : a structural interpretation
Moersch, Mathias; Nautz, Dieter - 1998
We emphasize the importance of properly identifying the long-run relations underlying the monetary model of the exchange rate. The separate estimation of long-run money demands leads to a "structural" error correction equation which allows an interpretation of the various channels affecting the...

Sequential versus independent commitment : an indirect evolutionary analysis of bargaining rules
Güth, Werner - 1998 - Rev.
Rational bargaining behavior depends crucially on the rules of bargaining, especially on whether parties decide sequentially or independently. Whereas in ultimatum bargaining the proposer can exploit the responder, independent commitments result in more balanced payoffs. To limit the scope of...

Smooth discrimination analysis
Mammen, Enno; Cybakov, Aleksandr B. - 1998
Discriminant analysis for two data sets in IRd with probability densities f and g can be based on the estimation of the set G = {x : f(x) ≥ g(x)}. We consider applications where it is appropriate to assume that the region G has a smooth boundary. In particular, this assumption makes sense if...
