I’m not an expert, but I assume (from a glance at the second paper) this is because the 1%-59% is a cost (opportunity cost), not a value of a life year as such; i.e. in a very poor country you can extend a life by a year for as little as $3, maybe with a vaccine or micronutrient supplement. Actually that seems an order of magnitude too low to me; but nonetheless, it’s a great deal!
Hm. It may be both—the opportunity cost (if one loses one QALY, they lose some percentage of annual income) and the value it costs to extend life for one QALY (e. g. through vaccine or micronutrient supplementation).
I actually dread it is the opportunity cost only, to which healthcare intervention costs are compared. For example, if an additional farmer contributes only $3 per year, because their work can be done by family members, then a global health organization will not support that farmer’s health if it costs more than $3 per QALY.
