We consider two semiparametric models for the weight function in a biased sample model. The object of our interest parametrizes the weight function, and it is either Euclidean or non Euclidean. One of the models discussed in this paper is motivated by the estimation the mixing distribution of...

State price density (SPD) contains important information concerning market expectations. In existing literature, a constrained estimator of the SPD is found by nonlinear least squares in a suitable Sobolev space...

In this paper we estimate and empirically test different behavioral theories of consumer reference price formation. Two major theories are proposed to model the reference price reaction: assimilation contrast theory and prospect theory. We assume that different consumer segments will use...

This paper presents a survey on panel data methods in which I emphasize new developments. In particular, linear multilevel models with a new variant are discussed. Furthermore, non linar, nonparametric and semiparametric models are analyzed. In contrast to linear models there do not exist...

The famous game of two cars is a pursuit-evasion dynamic game. In theextended version presented here, a correct driver (evader) on a freeway detectsa wrong-way driver (pursuer in a worst case scenario), i.e., a car driving on thewrong lanes of the road or in the wrong direction. The correct...

In klassischen Wahlmodellen wird davon ausgegangen, dass sich ein beobachtetes Verhalten durch einen nicht näher spezifizierbaren Evaluationsprozess des beobachteten Individuums ergibt. Ist die Aufdeckung dieses Prozesses von Interesse, stoßen reine Wahlmodelle schnell an ihre methodischen...

We use spline interpolation to approximate the subjective cumulative distribution function ofan economic agent over the future realization of a continuous (possibly censored) randomvariable. The method proposed exploits information collected using a small number ofprobability questions on...

Der Strommarkt in Deutschland befindet sich seit einigen Jahren in einem Liberalisierungsprozess,der zu einem Anstieg der Strompreisvolatilität führt. Für Elektrizitätshandelsunternehmengewinnt damit das Management des Strompreisrisikos eine zentrale Bedeutung. Vordiesem Hintergrund...

Factor based forecasting has been at the forefront of developments in the macroeconometricforecasting literature in the recent past. Despite the flurry of activityin the area, a number of specification issues such as the choice of the number offactors in the forecasting regression, the benefits...

In this paper we have developed a financial model of the non-life insurer to provide assistance for the management of the insurance company in making decisions on product, investment and reinsurance mix. The model is based on portfolio theory and recognizes the stochastic nature of and the...
