Thanks for sharing this, Owen! I appreciate that you frequently publish your work on LW and the EA forums.
I feel that formalizing the concept of neutral time cost (the number of neutral hours needed to complete an activity) helped me to think about comparative and absolute advantages in a new and helpful way.
Specifically, let's imagine that Alice and Bob are freelance report writers who have control over how much time they spend working every week, and who tend to produce reports of equal quality. If Alice can write reports slightly faster than Bob, but Alice hates writing, and needs much more time to recuperate after an hour of writing than Bob does, then Bob could be thought of as having an absolute advantage in report-writing.
I like this application. I'd thought about the intra-personal version where I should allocate tasks for myself in time according to mental state and current NTC of the task, but the inter-personal version may be even more natural.
Prioritisation is mostly about working out how to trade different resources off against one another. Prioritisation problems come at different scales: for individuals, for companies or organisations, for the world at large. At the Global Priorities Project we’re mostly interested in the large-scale questions. But we sometimes have something to say about smaller scale problems, too.
I’ve just tidied and released old research notes (mostly from 2013) on the personal prioritisation problem of how to value time spent on different activities. This is primarily of use for individuals making decisions about how to spend their time, money, and mental energy.
There may be benefits for broader prioritisation questions. Since societies are comprised of individuals, it could help to know how to value time savings or costs to individuals when performing cost-benefit analysis on larger projects. And there may be techniques for comparing between different resources that we could usefully apply in wider contexts. However we think these benefits are secondary. We’re releasing this work now to let others take advantage of it: either for personal benefit; or to build on it and release easier-to-use guidance or tools.
