Abstract: |
We study the measurement of well-being when individuals have heterogeneous
preferences, including different conceptions of a life worth living. When
individuals differ in the conception of a life worth living, the equivalent
income can regard an individual whose life is not worth living as being better
off than an individual whose life is worth living. In order to avoid this
paradoxical result, we reexamine the ethical foundations of well-being
measures in such a way as to take into account heterogeneity in the conception
of a life worth living. We derive, from simple axioms, an alternative measure
of well-being, which is an equivalent income net of the income threshold
making lifetime neutral. That new well-being index always ranks an individual
whose life is not worth living as worse-off than an individual with a life
worth living. |
