We use field experiments to examine the temporal stability of risk preferences. Over a 17-month period, we elicited risk preferences from subjects chosen to be representative of the adult Danish population. During this period we revisited many of these subjects and repeated a risk aversion elicitation task. We find some variation in risk attitudes over time, but we do not detect a general tendency for risk attitudes to increase or decrease over a 17-month span. The results also suggest that risk preferences are state contingent with respect to personal finances.
