Accounting for Foregone Pay

While the effective altruism movement started out with a strong focus on donations, over time it has shifted more towards careers. If you're trying to understand how levels of commitment have changed over time, or you're just trying to get a ballpark estimate of the financial opportunity cost of choosing a lower paying career, this can be quite tricky.

For someone earning to give this is relatively straightforward: AGB recently wrote a thoughtful post looking back at ten years of earning to give, and a statistic he gives is that he and his wife have donated an average of ~£150k over ten years, on a combined income averaging ~£320k. Clear cut! [1]

The case of someone choosing a lower-paying higher-impact career seems initially relatively simple: perhaps they're currently paid $100k, and if we look at their highest paying opportunity maybe they would be paid $300k, so we could say they're effectively sacrificing 2/3 or $200k. But this misses several factors that point in different directions:

This isn't a competition, and we don't need to be able to decide how much a specific person is giving up with the goal of making the world better. But making aggregate estimates with the goal of understanding things like how commitment within EA has changed over time is still valuable, and without considering some of these stickier factors it's easy to be way off.

(This also gives me a better appreciation for why the Giving What We Can pledge only counts donation via salary sacrifice if it's easily reversed.)


[1] But of course the real world is always messy. He writes that in 2018 he dramatically changed his career for EA reasons in ways that decreased his long-term earnings, and we should probably count that somehow.
