HOW TO ADAPT TO CHANGING MARKETS: EXPERIENCE AND PERSONALITY IN A REPEATED INVESTMENT GAME

Investment behavior is traditionally investigated with the assumption that it is on average advantageous to invest. However, this may not always be the case.

Expected returns from investment in the advantageous environment were higher than a safe alternative, while expected returns were lower in the disadvantageous environment. We investigate how experience and personality are related to choices. Investment behavior does not differ dependent on expected returns and professionals do not significantly differ from students. Personality predicts behavior and in particular we observe that openness to experience was an asset in unfavorable markets, leading to reduced risk taking
