Differences in Subjective Risk Thresholds: Worker Groups as an Example
利用工人样本，发现不同教育水平的工人对活动是否“有风险”的主观阈值存在系统性差异，并估计了这种差异对评估工资-风险权衡的影响。
Subjective risk perceptions are often encoded as responses to 0-1 questions in surveys or other qualitative risk scales. However, reference points for assessing an activity as risky are confounded by various characteristics of the respondents. This paper uses a sample of workers for whom quantitative risk assessments as well as dichotomous risk perception responses are available. It is shown that, given a quantitative risk measure, the thresholds for assessing an activity as “risky” vary systematically, particularly by education. The differences in such thresholds across worker groups are estimated. The resulting implications of using qualitative risk variables for assessing wage-risk tradeoffs are estimated, yielding results that are also relevant for many other areas involving similar qualitative variables.
