Weighing Animal Welfare

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.
