Notes

Many thanks to Paul Dolan and Eric Posner for their comments.

1. More precisely, these age thresholds would emerge from a combination of (1) using life as the “currency” for equity; (2) adopting an ex post rather than ex ante approach; and (3) using whole lifetimes rather than periods or moments as the temporal framework for measuring individual “holdings” of the “currency.” This last issue is discussed below, in the section on comparative and noncomparative views.

2. Sen argues that the currency for equality should be “capabilities,” which are opportunities to achieve “functionings.” (Sen 1992) In practice, much of the Sen-inspired work in development economics has used “functionings” not “capabilities,” given the difficulty of measuring opportunities (Laderchi 2003, 255). I therefore generally use the term “functioning” in discussing the Sen-inspired approach.

3. Using lifetimes as the relevant time period for measuring well-being achievements with respect to the “life” dimension means measuring the equity impact of a policy as the change in the number of deaths that occur before some age threshold. By contrast, using moments as the equity period means measuring the change in longevity (the total years that individuals are alive). On this approach, each increment to longevity relieves a momentary deprivation.
