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...

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...

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...

How do people cope with tail risk? In a lab experiment that removed informational and incentive confounds, subjects overwhelmingly behaved like Bayesian learners. The results of simulations further revealed that if one is to survive under tail risk, one needs to follow the Bayesian approach, as...

Neoclassical finance assumes that investors are Bayesian. In many realistic situations, Bayesian learning is challenging. Here, we consider investment opportunities that change randomly, while payoffs are observable only when invested. In a stylized version of the task, we wondered whether...

In this paper, we conduct a quantitative, qualitative and neuro-economic experiment investigating the effects of risk-preferences and emotions on investors' trading strategies and performance. The focus of our experiment is a computerised simulated trading game, where investors decide, on a...

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...

Price paths are oftentimes the only graphical representation of financial products investors receive before making an investment decision. We argue that price paths serve as graphical frames, influencing the perceived attractiveness of an asset by highlighting specific asset characteristics. In...

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...

We are currently at a unique moment in human history where demographic changes are and will continue to drastically alter the profile of decision makers in the global population. These changes highlight the challenges (e.g., rising entitlement costs) but also opportunities of a graying...
