We consider consistent tests for stochastic dominance efficiency at any order of a given portfolio with respect to all possible portfolios constructed from a set of assets. We justify block bootstrap approaches to achieve valid inference in a time series setting. The test statistics are computed...

Starting from the reward-risk model for portfolio selection introduced in De Giorgi (2004), we derive the reward-risk Capital Asset Pricing Model (CAPM) analogously to the classical mean-variance CAPM. The reward-risk portfolio selection arises froman axiomatic definition of reward and risk...

In this paper we experimentally test skewness seeking at the individuallevel. Several prospects that can be ordered with respect to the third-degreestochastic dominance (3SD) criterion are ranked by the participants of theexperiment. We find that the skewness of a distribution has a...

We study how the framework of classical game theory changes whenthe preferences of the players are described by Prospect Theory (PT)and Cumulative Prospect Theory (CPT) instead of Expected UtilityTheory. Specically, we study the inuence of framing eects and probabilityweighting on the existence...

Portfolio choice and the implied asset pricing are usually derived assumingmaximization of expected utility. In this Paper, they are derived from risk-value models that generalize the Markowitz-model. We use a behaviourally-based risk measure with an endogenous or exogenous benchmark...

In this paper the authors experimentally test overconfidence in investment decisions by ordering participants the possibility to substitute their own for alternative investment choices.

The paper shows that financial market equilibria need not exist if agents possess cumulative prospect theory preferences with piecewise-power value functions. The reason is an infiniteshort-selling problem. But even when a short-sell constraint is added, non-existence can occur due to...

We conduct controlled experiments in order to analyze individual trading behavior. Our results suggest that investors measure their gains relative to their initial wealth, and that this reference point together with past stock price changes determine the portfolio choices. Subjects choose a...

The wealth dynamics of insurance companies strongly depends on the success of their investment strategies, but also on liquidity shocks which occur during unfavorable years, when indemnities to be paid to the clients exceed collected premia. An investment strategy that does not take liquidity...

This paper studies an application of a Darwinian theory of portfolioselection to stocks listed in the Dow Jones Industrial Average (DJIA).We analyze numerically the long-run outcome of the competition offix-mix portfolio rules in a stock market with actual DJIA dividends.In the model seemingly...
