Using philosophical assumptions and placeholder estimates from the Rethink Priorities Moral Weights Project, I estimated the cost-effectiveness of farmed fish slaughter commitments to be between $10.4K and $114M per DALY averted. To put these numbers in context, $50 per DALY averted is considered a proxy for some of the most promising human global health and development interventions. The best animal interventions are often considered to be even more competitive than this." | ||||||||||||||||||||

Animal welfare In non-anthropocentric cost-benefit analysis and social welfare functions: A critical review to guide practical application. PSI Structural Genomics Knowledgebase. https://doi.org/10.22004/ag.econ.347466 | a critical review of the scientific and grey literature with the aim to synthesise the available material, to facilitate an informed debate on conflicting normative assumptions, and to eventually guide the practical application of non-anthropocentric cost-benefit analysis and social welfare functions. The results of the critical review are presented in the form of a checklist that allows to better comprehend key steps of the methodologies. Step-by-step, the checklist gives an overview of the alternative options and normative assumptions in the literature, and points to any remaining research gaps. Beside the academic debate, this is relevant for practical policy analysts who need to make methodological choices for their policy questions at hand | |||||||||||||||||||||
