We could also read “impact/resource - opportunitycost/resource” as a cost-effectiveness estimate that takes opportunity costs into account. I think Charity Entrepreneurship has been optimizing for this (at least sometimes, based on the work I’ve seen in the animal space) and they refer to it as a cost-effectiveness estimate, but I think this is not typical in EA.
If impact/resource is much bigger than opportunitycost/resource (so that the latter is negligible) this is roughly equal to impact/resource * resource, which is one reading of cost-effectiveness * scale.
Also, this is looking more like cost-benefit analysis than cost-effectiveness analysis.
Good point.
