LOST IN STATE SPACE: ARE PREFERENCES STABLE?*
通过田野实验，在17个月内多次测量丹麦成年人的风险偏好，发现风险态度随时间有变化但无整体增减趋势，且风险偏好与个人财务状况的状态相关。
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.
