Why retail investors traded equity during the pandemic? An application of artificial neural networks to examine behavioral biases
2021
Behavioral biases are known to influence the investment decisions of retail investors. Indeed, extant research has revealed interesting findings in this regard. However, the literature on the impact of these biases on millennials' trading activity, particularly during a health crisis like the COVID-19 pandemic, as well as the equity recommendation intentions of such investors, is limited. The present study addressed these gaps by investigating the influence of eight behavioral biases: overconfidence and self-attribution, over-optimism, hindsight, representativeness, anchoring, loss aversion, mental accounting, and herding on the trading activity and recommendation intentions of millennials …
Can personality predict retirement behaviour? A longitudinal analysis combining survey and register data from Norway.
2017
Published version of an article in the journal: European Journal of Ageing. Also available from the publisher at: http://dx.doi.org/10.1007/s10433-011-0212-6 This study investigates how far personality can predict the timing and routes of people’s retirement. It uses a large comprehensive Norwegian survey, with larger sample size than earlier related studies, providing estimates of personality based on the five-factor model. The survey data are matched with administrative data, allowing observations of retirement over the 2002–2007 period. The analysis distinguishes between the disability and the non-disability retirements. Retirement is investigated using discrete time, competing risk, log…
Dealing with risk: Gender, stakes, and probability effects
2015
This paper investigates how subjects deal with financial risk, both "upside" (with a small chance of a high payoff) and "downside" (with a small chance of a low payoff). We find that the same people who avoid risk in the downside setting tend to make more risky choices in the upside one. The experiment is designed to disentangle the probability-weighting and utility-curvature components of risk attitudes, and to differentiate settings in which gender differences arise from those in which they do not. Women are more risk averse for downside risks, but gender differences are diminished for upside risks.
Work-related and personal predictors of COVID-19 transmission: evidence from the UK and USA
2021
ObjectiveTo develop evidence of work-related and personal predictors of COVID-19 transmission.Setting and respondentsData are drawn from a population survey of individuals in the USA and UK conducted in June 2020.Background methodsRegression models are estimated for 1467 individuals in which reported evidence of infection depends on work-related factors as well as a variety of personal controls.ResultsThe following themes emerge from the analysis. First, a range of work-related factors are significant sources of variation in COVID-19 infection as indicated by self-reports of medical diagnosis or symptoms. This includes evidence about workplace types, consultation about safety and union memb…
Exploring non-cognitive predictors of mathematics achievement among 9th grade students
2017
Abstract This article explores the role of mathematics self-beliefs, as well as personality traits, social attitudes and well-being in students' mathematics achievement. The analysis builds on a Web survey of 9th grade students in Latvia (N = 3083). Based on a hierarchical multilevel regression analysis we find that personality, social attitudes and wellbeing variables matter more for mathematics achievement than sociodemographic variables, yet mathematics self-beliefs account for an even larger amount of variance over and above that accounted for by sociodemographic variables and personality, social attitudes and well-being. Mathematics self-beliefs, most of all mathematics self-concept, w…
Social information use about novel aposematic prey is not influenced by a predator’s previous experience with toxins
2019
Aposematism is an effective antipredator strategy. However, the initial evolution and maintenance of aposematism are paradoxical because conspicuous prey are vulnerable to attack by naive predators. Consequently, the evolution of aposematic signal mimicry is also difficult to explain. The cost of conspicuousness can be reduced if predators learn about novel aposematic prey by observing another predator's response to that same prey. On the other hand, observing positive foraging events might also inform predators about the presence of undefended mimics, accelerating predation on both mimics and their defended models. It is currently unknown, however, how personal and social information combi…
Extraversion and performance approach goal orientation : An integrative approach to personality
2019
Abstract Research shows that extraversion is unrelated to performance approach goal orientation, both at the trait- and the state-level. However, since previous studies have either focused on the trait- or the state-level, such a conclusion may be premature. Building upon the idea that acting against one’s trait consumes self-control resources, we reason that within-person deviations from one’s level of trait extraversion might negatively relate to performance approach goal orientation. Using experience sampling data from 47 employees across 10 days (N = 307), we found that deviations from one’s trait extraversion levels are associated with lower levels of performance approach goal orientat…
Rasgos de personalidad, bienestar y malestar psicológico en usuarios de redes sociales que presentan conductas disruptivas online
2021
The present study focused on the analysis of online disruptive behavior that usually occurs among social network users. Individuals who perpetrate such behavior are commonly known as trolls or haters (Cheng, Danescu-Niculescu-Mitzil, & Leskovec, 2015). In general, they post comments, photos or provocative videos that do not pursue any purpose other than annoying or obtaining pleasure or fun (Brandel, 2007; Phillips, 2011). Recent studies have shown that certain personality traits are associated with the presence of such disruptive behavior. In this research, we studied normal personality traits, psychopathological traits, and dark personality traits in relation to disruptive behavior. The n…
Risk aversion in prediction markets: A framed-field experiment
2016
International audience; To make better decisions today, companies and other economic agents are interested in getting accurate predictions of future events. Prediction markets can, at least potentially, give those accurate forecasts for the probability of the event by aggregating information from traders. However, formal studies highlight that the risk attitudes of market participants may bias the market equilibrium prices, and consequently make the prediction unreliable. This research examines the effect of participants' risk attitudes on prediction market prices, through a framed field experiment on the two semifinals at the 2015 NCAA Men's Division Basketball Tournament. The results of t…
Loss Aversion and Risk Aversion in Non-Clinical Negative Symptoms and Hypomania
2020
In the field of behavioral decision-making, “loss aversion” is a behavioral phenomenon in which individuals show a higher sensitivity to potential losses than to gains. Conversely, “risk averse” individuals have an enhanced sensitivity/aversion to options with uncertain consequences. Here we examine whether hypomania or negative symptoms predict the degree of these choice biases. We chose to study these two symptom dimensions because they present a common theme across many syndromes with compromised decision-making. In our exploratory study, we employed a non-clinical sample to dissociate the hypomanic from negative symptom dimension regarding choice behavior. We randomly selected a sample …
