In the experimental scenario several agents repeatedly invest in n (n _ 2)state-specic assets. The evolutionarily stable and equilibrium (Blume andEasley, 1992) portfolio for this situation requires to distribute funds accordingto the constant probabilities of the various states. The dierent...

An empirically well-established finding is that equity portfolios are concentratedin the domestic equity market of the investor. Previous theoreticaland empirical analyses have mainly focused on institutional explanations andlargely neglected individual behavior. In this study we report the...

We experimentally test overconfidence in investment decisions by offering participants the possibility to substitute their own for alternative investment choices.Overall, 149 subjects participated in two experiments, one with just one risky asset, the other with two risky assets. Overconfidence...

This paper focuses on egocentric biases in financial decisions. Subjects first designa portfolio, whereby each combination of assets yields the same expected returnand variance of returns. They are then confronted with two alternative portfolios;the average portfolio and the portfolio of one’s...

The results of an asset market experiment, in which 64 subjects trade two assets oneight markets in a computerized continuous double auction, indicate that objectivelyirrelevant information influences trading behavior. Moreover, positively and negativelyframed information leads to a particular...

This paper investigates (i) the robustness of hindsight bias in experimental assetmarkets, (ii) the time invariance of the different experimental risk elicitationmethods of certainty equivalents and binary lottery choices, and (iii) their correspondence.The results of our within-subjects...

Empirical evidences show that investors tend to be biased toward investing indomestic (home bias) and local (local bias) stocks. Familiarity is considered to be one of thereasons. A similar concept was proposed by Goldstein and Gigerenzer (1999, 2002), known asthe recognition heuristic: “when...

How do people make investment decisions when they receive outcome feedback? We examinedhow well the standard mean-variance model and two reinforcement models predict people’sportfolio decisions. The basic reinforcement model predicts a learning process that relies solelyon the portfolio’s...

We examine in an experiment the causes, consequences and possible cures ofmyopic loss aversion (MLA) for investment behaviour under risk. We find thatboth, investment horizons and feedback frequency contribute almost equally tothe effects of MLA. Longer investment horizons and less frequent...

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...
