Genetic Determinants of Financial Risk Taking
AbstractIndividuals vary in their willingness to take financial risks. Here we show that variants of two genes that regulate dopamine and serotonin neurotransmission and have been previously linked to emotional behavior, anxiety and addiction (5-HTTLPR and DRD4) are significant determinants of risk taking in investment decisions. These findings provide novel evidence of a genetic basis for financial choices.
