Young novice drivers constitute a major public health concern due to the number of crashes in which they are involved, and the resultant injuries and fatalities. Previous research suggests psychological traits (reward sensitivity, sensation seeking propensity), and psychological states (anxiety, depression) influence their risky behaviour. The relationships between gender, anxiety, depression, ...

The current study examined whether the association between the occurrence of negative events and increased engagement in risky behavior is moderated by maladaptive and/or adaptive coping strategies. At time 1, 411 adolescents (ages 14-19) from Yue Yang, Hunan, completed self-report measures assessing coping strategies, engagement in risky behaviors, and the occurrence of negative events. Once a...

The consequences of risky sexual behavior are of public concern. Adolescents contribute disproportionately to negative consequences of risky sexual behavior. However, no research has examined the neural correlates of impulse control and real-world engagement in risky sexual behavior in this population. The aim of the present study was to examine this question. Twenty sexually active adolescents...

Because the less informed incorrectly estimate asset returns, they anticipate higher returns from their risky investments. They thus over-invest in risky securities. They are rewarded by higher total portfolio returns. Too high a proportion of less informed investors lowers the return on risky assets. Equilibrium requires that the less informed’s rate of return equal the informed’s. The less in...

We consider the optimal intertemporal consumption and investment policy of a constant absolute risk aversion (CARA) investor who faces fixed and proportional transaction costs when trading multiple risky assets. We show that when asset returns are uncorrelated, the optimal investment policy is to keep the dollar amount invested in each risky asset between two constant levels and upon reaching e...

AIM The purpose was to establish how the association between socioeconomic disadvantage and risky drinking depends on the indicator of risky alcohol-drinking patterns. METHODS Alcohol-drinking Finnish men (n = 9316) and women (n = 11,888) aged 20-54 years at baseline participated in the Health and Social Support (HeSSup) postal survey in 1998. Socioeconomic disadvantage was measured by low ed...

The present study aims at evaluating and comparing risky behaviors of injecting and non-injecting drug users. Methods: In this cross-sectional descriptive study, 4400 addicts referred to public, priva...

BACKGROUND Co-morbidity with substance use disorders negatively influences overall functioning in patients with psychosis. However, frequencies and courses of risky use of alcohol, drugs and cigarettes are rarely investigated in patients at psychosis units. The purpose of this study is to describe the use of alcohol, drugs and cigarettes in patients at a psychosis unit over a 1 1/2 year period ...

Individual-Level Loss Aversion in Riskless and Risky Choices Loss aversion can occur in riskless and risky choices. Yet, there is no evidence whether people who are loss averse in riskless choices are also loss averse in risky choices. We measure individual-level loss aversion in riskless choices in an endowment effect experiment by eliciting both WTA and WTP from each of our 360 subjects (rand...
