The exploitation of participants is a significant problem in biomedical research, especially in the developing world. However, there is a gap between this problem and the theoretical literature on exploitation. This thesis will attempt to bridge it, considering Wertheimer and Sample’s theories. Whereas Wertheimer holds that exploitation is merely an unjust distribution of the “social surplus” arising from a transaction, Sample, whose approach this thesis endorses, construes exploitation as a lack of respect for a person’s true value. This thesis will (...) show that codes of ethics with legal force take a Wertheimerian approach, and that the aspirational codes, which insist that research respond to local health priorities, are more Samplian. Finally, it will argue that the current system of research funding and oversight cannot guarantee that research is responsive to the needs of the developing world and thus fails to prevent exploitation.
