Presented is the formulation for determining the exact, expected growth-optimal fraction of equity to risk for all conditions, rather than merely the asymptotic growth-optimal fraction. The formulation presented represents the surface in the leverage space manifold, wherein the loci at the peak...

We analyze investors’ trading behavior, particularly their coping with fundamental shocks in asset value, depending on individual differences in the sensitivity of two basic neurophysiological systems—the Behavioral Approach System (BAS), the ‘driving force’ of human behavior, and the...

The disposition effect, i.e., the tendency to sell winning stocks too early and losing stocks too late is one of the most frequently observed and discussed biases of financial investors. We investigate in a laboratory experiment whether the option of automatic selling devices causally reduces...

: We report the results of two laboratory experiments that study how university student and staff participants chose retirement savings investment options using ‘user-friendly’ information prescribed by regulators. We demonstrate that choices of more than 20% of participants cannot be...

How do investors perceive dependence between stock returns? And how does their perception of dependence affect investments and stock prices? We show experimentally that investors understand differences in dependence, but not in terms of correlation. Participants invest as if applying a simple...

The underlying physiological mechanisms of biases are not well understood. As such, we examine the impact of testosterone and cortisol levels on several commonplace investment biases using realistic trading simulations. Cortisol, the biological marker of stress, is positively related to the...

We study the impact of colors of paintings on prices in the art auction market and incorporate color attributes of non-figurative paintings in pricing models. A one standard deviation increase in the percentages of blue (red) hue leads to premiums of 10.63% (4.20%). We also conduct laboratory...

Purpose – The purpose of this paper is to derive the determinants of young adults' subjective and objective risk attitude in theoretical and real-world financial decisions. Furthermore, a comparison of the factors that influence young adults' and older adults' risk attitude is...

Do women and men behave differently in financial asset markets? Our results from an asset market experiment using the Smith, Suchaneck, and Williams (1988) framework show marked gender difference in producing speculative price bubbles. Using 35 markets from different studies, a meta-analysis...

We analyze the impact of individuals' degree of extraversion and neuroticism on their decision making in an experimental asset market. To establish this link between research on experimental asset markets and social psychology we use a unique approach that combines a questionnaire designed to...
