Research Abstract	We explore to what extent genetic factors account for interpersonal variation in preferences for risk taking and giving. By adopting a mixed-effects Baysian ACE model using Markov Chain Monte Carlo method, we find that substantial parts of the variations are explained by both genetic additive genetic factors and common environmental factors: For risk aversion, 25% of the variation can be accounted for by additive genetic factors and 24% by common environmental factors; for giving, 21% and 24% of the variation can be influenced by additive genetic factors and common environmental factors, respectively.
