This chapter focuses on the inner rationale and consequences of four different archetypal positions regarding how ethical and political values are tackled in welfare economics. Welfare economics is standardly associated with the welfarist framework, for which social welfare is based on individual utility only. Beyond this, we distinguish the value-neutrality claimfor which ethical values should be and are out of the scope of welfare economics-, the value confinement idealfor which ethical values are acceptable if they are minimal and consensual-, the transparency requirementfor which any ethical values may be acceptable in the welfare economics framework if explicit and formalized-, and the entanglement claimwhich challenges the very possibility of demarcation between facts and values.
