We estimate that around 1300 people went to wrap parties (adjusted somewhat for how long they were there for). This was based on examining the list of events and their purported attendances, and a few quick checks for verification.
We estimated Oliver’s impact was 1⁄4 of the impact of the wrap parties. We estimated that the existence of cental organization doubled the scale of the event, and we attributed half of that credit to the central organization and half of the credit to other local organizers and non-organizational inputs (which also had to scale up).
We estimated that the attendance of an additional person was worth around $15 of stimulated EA donations. This was a guess based on a few different lines of reasoning. We estimated the value of the EA/LW community in stimulated donations, the value of annual growth, the fraction of that growth that comes from outreach (as opposed to improving the EA product, or natural social contact), and the fraction of outreach that came from the wrap parties. We also guessed what fraction of people were new, would become more involved in the EA/LW community as a result, and how much value that would create. We sanity checked these numbers against the kind of value participants probably got from the celebration individually.
So we have 1300 * 15 /4 = $4,875 of stimulated EA donations, which we rounded up to $5,000.
Submission: Oliver Habryka’s organization of wrap parties for the conclusion of Harry Potter and the Methods of Rationality, summarized here.
We purchase 3% in round 1 for $400, which we resold to Larks for $300 in round 3. Larks purchased 6.9% for $700 in round 3.
Current holdings:
Oliver: 90.1%
Larks: 9.9%
Our very rough evaluation:
