GENDER DIFFERENCES IN RISK BEHAVIOUR: DOES NURTURE MATTER?

See on Scoop.itBounded Rationality and Beyond

Using a controlled experiment, we investigate if individuals’ risk preferences are affected by (i) the gender composition of the group to which they are randomly assigned, and (ii) the gender mix of the school they attend. Our subjects, from eight publicly funded single-sex and coeducational schools, were asked to choose between a real-stakes lottery and a sure bet. We found that girls in an all-girls group or attending a single-sex school were more likely than their coed counterparts to choose a real-stakes gamble. This suggests that observed gender differences in behaviour under uncertainty found in previous studies might reflect social learning rather than inherent gender traits.

Nature or nurture: What determines investor behavior?

See on Scoop.itBounded Rationality and Beyond

Using data on identical and fraternal twins’ complete financial portfolios, we decompose the cross-sectional variation in investor behavior. We find that a genetic factor explains about one-third of the variance in stock market participation and asset allocation. Family environment has an effect on the behavior of young individuals, but this effect is not long-lasting and disappears as an individual gains experience.
Frequent contact among twins results in similar investment behavior beyond a genetic factor. Twins who grew up in different environments still display similar investment behavior. Our interpretation of a genetic component of the decision to invest in the stock market is that there are innate differences in factors affecting effective stock market participation costs. We attribute the genetic component of asset allocation—the relative amount invested in equities and the portfolio volatility—to genetic variation in risk preferences.
