Corruption has been a rather problematic topic in the anthropological investigation; this is explained by the comparatively small number of works that expressly deal with this phenomenon in the discipline. This silence in the anthropological literature (in spite of a growing interest detectable since the early 2000s) is justified by looking at epistemological, deontological, and methodological concerns. This entry proposes three approaches through which anthropology has introduced new and extremely timely perspectives to the phenomenon: the normative, the hermeneutical, and the transactional approaches. In particular, the transactional approach has produced a number of interesting insights in the economic–anthropological sphere, as related to social exchange theory.
