最近，基于明确的公平原则和尊重个人偏好的货币计量措施恢复了多维福利分析。为了使这种方法具有可操作性，偏好异质性可以从对个人选择的观察（显示偏好）或从这些选择后自我宣称的满意度（主观幸福感）中推断出来。我们的问题是否使用一种或另一种方法，使福利分析的基础上的收入休闲偏好的差异。我们估计序数的偏好，无论是符合实际的劳动力供应的决定或收入休闲满意度。对于基于补偿原则的道德先验，我们比较了两种方法获得的福利排名。福利等级的相关性一般较高，77%的人重新排名不重要。其余的差异可能涉及各种因素，包括限制（健康问题，劳动力市场配给），非理性行为和追求幸福的替代生活选择。我们讨论了使用一个或其他的偏好引出方法的福利分析的影响。
Multidimensional welfare analysis has recently been revived by money-metric measures based on explicit fairness principles and the respect of individual preferences. To operationalize this approach, preference heterogeneity can be inferred from the observation of individual choices (revealed preferences) or from self-declared satisfaction following these choices (subjective well-being). We question whether using one or the other method makes a difference for welfare analysis based on income-leisure preferences. We estimate ordinal preferences that are either consistent with actual labor supply decisions or with income-leisure satisfaction. For ethical priors based on the compensation principle, we compare the welfare rankings obtained with both methods. The correlation in welfare ranks is high in general and reranking is insignificant for 77% of the individuals. The remaining discrepancies possibly pertain to a variety of factors including constraints (health issues, labor market rationing), irrational behavior and alternative life choices to the pursuit of well-being. We discuss the implications of using one or the other preference elicitation method for welfare analysis.
