Thanks for reading and commenting. I agree with some of your takes, some of which are in the post but some points of disagreement or at least partial disagreement.

"Less cost-effective"- this could operate at a profit and avoid taking philanthropic funds. So it wouldn't compete with other interventions. So even if it was less impactful in terms of welfare, I think it would be more cost-effective.

Existing local producers- I would be happy if they entered this market or if new producers did-I don't think my proposal of export-oriented humane chicken would affect current local producers in any negative way- mexico currently exports almost no chicken to the united states.

Elasticity- you cite the same sources in my post. the big questions are do you feel bad about chickens raised in "humane farms" being born or not? and what is the humane chicken own-price elasticity- I extrapolated from poultry in general but it could be higher or lower.

Good point. I think you would probably only consider the direct costs to those donors (pain/morbidity/risk) and not foregone donations, since presumably the typical liver donor participating in a chain is not devoting a lot of their earnings to impactful charity.

I only am familiar with the US system unfortunately. I think this evaluation holds up pretty well for EAs even though its some years old. 

Yes,  I agree it's frustrating. I did a more detailed one when considering living kidney donation. Plus, living liver donation is less common.

My fast liver donation BOTEC assumes 80k hours of working hours (reduce if older?).

1 in 250 chance of death (source, maybe too high)= -320 work hours

About a month of work lost due to recovery (source)= -160 work hours. 

So maybe spending 500 work hours to extend one persons life. 

Ignoring time off work due to potential reimbursment, if you netted $15 per hour for the hours lost to risk of death and donated you could probably save a life via AMF. My take is that liver donation probably falls below normal EA effectiveness for most EAs. In contrast, I think kidney donation makes sense for at least some EAs

If you think you have stronger obligation to Americans than other people, it might work out. Or if you think your donation could inspire others. It also depends on how impactful you think your job is directly. I will say I really admire liver donors even if it might not clear the bar of cost-effectiveness for many. 

More sympathetic to biosecurity issues than at the start of the year. Pretty convinced there are clear things that would be useful to do and help a lot of people. Plus, FTX situation cut out a lot of money that went to the general area such as SBF's brother's group-Guarding Against Pandemics.

Sales tax: Interesting. I live in a state with sales tax but it doesn't apply to lottery tickets.

Could also make sense for people who don't itemize so don't benefit from charitable deduction but would itemize if they won the larger prizes.
