supposing the improved conditions are 18.3 % as bad as the initial ones, as I estimated for moving broilers from a conventional to a reformed scenario
Update on June 4. Previously, I was using 22.3 %, but I have now changed to 27.0 % after correcting a small error.
Update on June 17. I have now changed to 18.3 % after correcting another error.
According to Colette Fox, head of School Plates, this swapped 12.4 M meals to meat-free in 2023 at a cost of approximately 155 k£, i.e. 192 k$ (= 155*10^3*1.24).
Update on June 7. Previously, I was using 6.2 M meals swapeed to meat-free, and a cost in 2023 of 200 k£, but I have now changed these values to the ones above based on new information shared by Colette.
Jimmy Pierson, director of ProVeg UK, mentioned the cost in 2023 was 63 % than in 2023, and that the impact in 2023 was 102 % higher than in 2022, which imply the cost per additional meat-free meal in 2023 was 80.7 % (= (1 + 0.63)/(1 + 1.02)) that in 2022. I take this to mean diminishing returns have not kicked in much yet, and therefore suppose the marginal cost-effectiveness is the same as the one in 2023. So I arrive at a marginal cost per additional meat-free meal of 0.0155 $.
Update on June 7. Previously, I was assuming the marginal cost-effectiveness to be 50 % of the cost-effectiveness in 2023, but I am now assuming they are equal based on feedback from Jimmy (see quote just above).
