Societal Support for Paying Plasma Donors in Canada
By Nicola Lacetera and Mario Macis

They begin with a concise statement of why repugnance is important for economics:

"The legal status and regulation of economic transactions do not depend only on considerations regarding their economic efficiency, but also on whether a society supports the occurrence of trades through a price mechanism (if at all). Concerns that individuals engaging in certain transactions may be exploited or unduly influenced, that the terms of trade may not be fair, or that some transactions violate human dignity, the sanctity of life, or traditional institutions may lead a society to prohibit certain trades. These principles may take priority over material considerations and may contribute to defining common identities or a collective conscience that allows complex societies to be tied together. "
