Immigration reform: a shallow cause exploration

In this shallow cause exploration, we explore the impact of immigration on subjective wellbeing. We review the literature, model the impact of immigration on wellbeing, and conduct some back-of-the-envelope calculations of the cost-effectiveness of various interventions to increase immigration.

Pain relief: a shallow cause exploration

In this shallow cause exploration, we explore the relationship between pain and subjective wellbeing; assess the severity and scale of chronic pain in terms of life satisfaction; and offer some novel back-of-the-envelope calculations for the cost-effectiveness of several interventions to treat pain.

A can of worms: the non-significant effect of deworming on happiness

In this report, we summarise the debate about the efficacy of deworming, present the first analysis of deworming in terms of subjective wellbeing, and compare the cost-effectiveness of deworming to StrongMinds (our current top recommended charity).

The elephant in the bednet: the importance of philosophy when choosing between extending and improving lives

How should we compare the value of extending lives to improving lives? Doing so requires us to make various philosophical assumptions, either implicitly or explicitly. But these choices are rarely acknowledged or discussed by decision-makers, all of them are controversial, and they have significant implications for how resources should be distributed.

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

We make four recommendations to improve GiveWell’s cost-effectiveness analyses: (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.

Cash transfers: systematic review and meta-analysis

We know that cash transfers reduce poverty, improve health and enhance education but what impact do they have on how people feel and think about their lives? We find that cash transfers have a small, positive effect on subjective wellbeing, one that lasts for several years.
