Weighing Animal Welfare

Book excerpt: When, if ever, is it better to spend money to improve pig welfare over chicken welfare? Which species of fish is worse off in commercial aquaculture operations? When, if ever, would humans benefit less from a policy than animals stand to lose? As governments, NGOs, and private actors regularly make decisions about these questions colored by particular views, this volume provides a methodology for making such comparisons, it puts that methodology into practice, and then reports some tentative, proof-of-concept results.
