This paper is the outcome of collaborative work between an economist a
nd a social anthropologist. It explores the differences of outlook and
approach between these two subjects, both in general, and in the spec
ific context of a research project, ''The Management of Cooperative St
rategies,'' which tests economistic hypotheses using methods largely d
erived from social anthropology. There remain major dissonanaces betwe
en the two subjects, but an attempt is made here to find fruitful comm
on ground.
