SIMULTANEOUS MEASUREMENT OF TIME AND RISK PREFERENCES: STATED PREFERENCE DISCRETE CHOICE MODELING ANALYSIS DEPENDING ON SMOKING BEHAVIOR*
提出一种新方法同时测量时间偏好率和风险厌恶系数，并分析这些偏好参数与吸烟行为的关系，发现当前吸烟者比非吸烟者更缺乏耐心且更偏好风险，重度吸烟者最明显，而戒烟者最耐心且最厌恶风险。
Measuring time and risk preferences and relating them to economic behaviors are important topics in behavioral economics. We developed a new method to simultaneously measure the rate of time preference and the coefficient of risk aversion. Analyzing the individual‐level relationships between preference parameters and cigarette smoking, we conclude that current smokers are more impatient and risk‐prone than nonsmokers. Heavy smokers are the most impatient and risk‐prone, whereas ex‐smokers are the most patient and risk‐averse. Among nonsmokers, neither age‐related nor gender‐related differences were found. On the other hand, risk and time preferences are significantly different according to age and gender for smokers.
