We analyze the influence of individuals’ degree of extraversion and neuroticism on the determinants of their risk-taking behavior in investment decisions. As there are no studies that investigate the influence of personality traits on risk attitude, risk perception, and return expectations in investment decisions simultaneously, we provide a meaningful contribution to existing literature. We use a unique data set that contains 342 undergraduate business students’ questionnaire responses measuring the students’ degree of extraversion and neuroticism as well as their risk attitude, risk perception, and return expectations. Therefore, we are able to identify which determinants of risk-taking are influenced by extraversion and neuroticism and induce individuals to take investment risks. We find that more extraverted individuals are less risk averse, whereas more neurotic subjects are more risk averse. Beside these results, we find that more conscientious individuals are more risk averse and perceive investments in assets as more risky. Further research should consider individuals’ personality as an influence factor on the determinants of risk-taking behavior in investment decisions.

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 provided. Design/methodology/approach The paper relies on an experimental setting and a cross-sectional field study using data of the German central bank’s (Deutsche Bundesbank) PHF-Survey. Findings Young adults’ objective risk aversion is not constant but increases with stake sizes. Furthermore, young adults’ subjective risk attitude is a better predictor for their objective risk attitude than a set of commonly employed socio-demographics and economics like age or income. Moreover, young adults’ subjective risk attitude works as a mediator for the influence of their investable financial wealth on their objective risk attitude. Although young adults’ subjective risk attitude shows a gender effect, the influence of young adults’ gender on their objective risk attitude decreases with higher stake sizes. Compared to older adults, young adults generally show a similar degree of subjective risk aversion. However, due to stronger financial restrictions, young adults show a higher degree of objective risk aversion. Originality/value Although individuals’ financial outcomes depend on the financial behavior established in young adulthood, there is no study that simultaneously analyzes the determinants of young adults’ subjective and objective risk attitude in real-world financial decisions with a focus on young adults as a separate age group. The paper closes this gap in literature and additionally provides a comparison of the subsamples of young adults and older adults. The analysis in this paper reveals that young adults’ lower engagement in financial markets is primarily driven by their tight budget and not by a fundamental different subjective risk attitude.

Purpose The purpose of this study is to analyze whether differences in market-wide levels of investor personality influence experimental asset market outcomes in terms of limit orders, price levels and price bubbles. Design/methodology/approach Investor personality is determined by a questionnaire. These data are combined with data from 17 experimental asset markets. Two approaches are used to estimate market-wide levels of investor personality. First, the market-wide average of each personality trait is determined; second, the percentage of individuals with comparable personality in a market is computed. Overall, 364 undergraduate business students participated in the questionnaire and the experimental asset markets. Findings Limits and transaction prices are higher in markets with higher mean values in participants’ extraversion and openness to experience and lower mean values in participants’ agreeableness and neuroticism. In markets with lower mean values of subjects’ openness to experiences more overpriced transactions are observed. In markets with a higher proportion of extraverted subjects and a lower proportion of neurotic subjects higher limits and transaction prices are observed. Bubble phases last longer in markets with a higher proportion of extraverted and a lower proportion of neurotic subjects. Originality/value Overall, the findings suggest that market-wide personality levels influence market outcomes. As a consequence, market-wide levels of personality help to explain prices in auctions with limited number of participants. Additionally, studies that analyze the influence of subjects’ characteristics, including risk aversion, emotional states or overconfidence, on market outcomes should also consider personality traits as potential underlying factor.
