Subjective well-being
NB It is important to distinguish between hedonic well-being (how good or bad you feel at any particular moment), and life-evaluation (how well people think their life is going), since these can point in different directions (e.g. with regard to activities like child-raising and work).

Theory:

Fair Allocations
"The theory of fair allocations studies the allocation of resources among people with different tastes and
abilities, subject to a number of fairness criteria, such as “no-envy” (i.e. no agent should prefer another’s bundle),
“solidarity” (e.g. no agent should be hurt by an increase in available resources) and “lower-bounds” (e.g. no agent
should prefer the equal-split solutions)."

Theory
See e.g. H. Varian, “Equity, envy, and efficiency,” Journal of Economic Theory 9, no. 1 (1974): 63–91.Link

Application
See e.g. wok by Marc Fleurbaey (who also worked on the Stiglitz-Sen-Fitoussi report).
