We examine in an experiment the causes, consequences and possible cures of myopic loss aversion (MLA) for investment behaviour under risk. We find that both, investment horizons and feedback frequency contribute almost equally to the effects of MLA. Longer investment horizons and less frequent feedback lead to higher investments. However, when given the choice, subjects prefer on average shorte...

Background: Macrosomia is a risk factor for adverse maternal and neonatal outcomes and previous studies have reported different prevalence of macrosomia in Iran. We conducted a meta-analysis to estimate the overall prevalence of macrosomia in Iran. Materials and Methods: A systematic review and meta-analysis was conducted of all published literature pertaining to prevalence rates of macrosomia ...

Our model adjusted for the most obvious of these (age and smoking), but there may be other unidentified factors. The strength of experimental studies is that randomi...

Thanks to a slew of popular new books, many executives today realize how biases can distort reasoning in business. Confirmation bias, for instance, leads people to ignore evidence that contradicts their preconceived notions. Anchoring causes them to weigh one piece of information too heavily in making decisions; loss aversion makes them too cautious. In our experience, however, awareness of the...

Myopic loss aversion (MLA) has been found to play a persistent role for investment behavior under risk. We study whether MLA is already present during adolescence. Quite surprisingly, we find no evidence of MLA in a sample of 755 adolescents. This finding is at odds with previous findings, and it might be explained by self-selection effects. In other dimensions, however, we are able to replicat...

Adverse selection and moral hazard are commonly expected to cause market failures in natural disaster insurance markets. However, such problems may not arise if individuals mainly buy insurance based on risk preferences. Advantageous selection can occur if individuals with insurance are highly risk averse and seek to reduce risk. We offer a comprehensive empirical study of risk selection in nat...

PURPOSE The aim was to review the methodological quality of trials to evaluate rehabilitation for spatial neglect and to determine the overall effectiveness of interventions METHODS A systematic literature review and meta-analysis were conducted of trials completed by 2005. Trials identified were independently assessed for methodological quality by two reviewers. Outcomes were analysed as the...
