‘Fair’ Welfare Comparisons with Heterogeneous Tastes: Subjective versus Revealed Preferences

Multidimensional welfare analysis has recently been revived by money-metric measures based on explicit fairness principles and the respect of individual preferences. To opera- tionalize 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 di¤erence 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 di¤erent ethical priors regarding work preferences, we compare the welfare rankings obtained with both methods. The correlation in welfare ranks is high in general and very high for the 60% of the population whose actual choices coincide with subjective well-being maximization. For the rest, most of the discrepancies seem to be ex- plained by labor market constraints among the low skilled and underemployment among low-educated single mothers. Importantly from a Rawlsian perspective, the identification of the worst off depends on ethical views regarding responsibility for work preferences and the extent to which actual choices are constrained on the labor market.JEL: C35, C90, D60, D63, D71, H24, H31, J2
