摘要：Many consumers are concerned with animal welfare in the conventional production of farm livestock. This concern can be related both to their own and others’ consumption. In the latter case, there is a negative externality from consumption. We suggest a survey design that enables us to test for a market failure in farm livestock production. Applying this to the question of battery cages in egg production, we cannot show that a market failure exists. The policy can be extended to general discussion of how potential market failures for all kind of farm livestock should be managed.
