To WELLBY or not to WELLBY? Measuring non-health, non-pecuniary benefits using subjective wellbeing

We propose the wellbeing-adjusted life year (WELLBY), the SWB equivalent of the DALY or QALY, as the obvious framework to do cost-effectiveness analyses of non-health, non-pecuniary benefits. As our previous work has shown, using WELLBYs can change funding priorities by giving more weight to improving mental health, compared to DALYs or income measures; and they may reveal different priorities in other areas too.

Deworming and decay: replicating GiveWell’s cost-effectiveness analysis

We provide four recommendations to improve the clarity and transparency of GiveWell’s cost-effectiveness analyses. These are to (1) publicly explain and defend their assumptions about the effect of deworming over time; (2) explain their cost-effectiveness analyses in writing; (3) illustrate the sensitivity of their results to key parameters; (4) make it clear when an estimate is subjective or evidence-based.

Happiness for the whole family

We update our previous analysis to incorporate the household spillover effects for cash transfers and psychotherapy. We estimate that psychotherapy is 9 times (95% CI: 2, 100) more cost-effective than cash transfers. The charity StrongMinds is estimated to be 9 times (95% CI: 1, 90) more cost-effective than the charity GiveDirectly.
