We present a model for the [alpha]-beauty contest that explains common patterns in experimental data of one-shot and iterative games. The approach is based on two basic assumptions. First, players iteratively update their recent guesses. Second, players estimate intervals rather than exact...

The 1-shot ?-beauty contest is a non-equilibrium strategic game under bounded rationality conditions, while equilibrium is approached if the game is played iteratively sufficiently many times. Experimental data of the 1-shot setting of the 0-equilibrium game show a common pattern: The spectrum...

We propose an affine term structure model which accommodates non-linearities in the drift and volatility function of the short-term interest rate. Such non-linearities are a consequence of discrete beta-distributed regime shifts constructed on multiple thresholds. We derive iterative closed-form...

Starting from the reward-risk model for portfolio selection introduced in DeGiorgi (2005), we derive the reward-risk Capital Asset Pricing Model (CAPM) analogously to the classical mean-variance CAPM. In contrast to the mean-variance model, reward-risk portfolio selection arises from an...

The portfolio selection problem is traditionally modelled by two different approaches. The first one is based on an axiomatic model of risk-averse preferences, where decision makers are assumed to possess an expected utility function and the portfolio choice consists in maximizing the expected...

Using canonical data for the US stock and bond markets, we show that the kinked piecewise exponential value function can rationalize the cross-section of stock returns in addition to the level of the equity premium, while the kinked piecewise-power value function of Tversky and Kahneman can...

The prospect theory of Kahneman and Tversky (in Econometrica 47(2), 263-291, 1979) and the cumulative prospect theory of Tversky and Kahneman (in J. Risk Uncertainty 5, 297-323, 1992) are descriptive models for decision making that summarize several violations of the expected utility theory....
