Veblen's concept of conspicuous consumption, although widely known and
commonly invoked, has rarely been examined critically; the associated
''theory'' has never been tested. Ir is suggested that the reason for
this lies in the difficulty of determining the criterion that defines
the phenomenon, a difficulty that derives from Veblen's failure to in
tegrate two contrasting conceptual formulations. These are, first, an
interpretive or subjective version that conceives of conspicuous consu
mption as action marked by the presence of certain intentions, purpose
s, or motives, and second, a functionalist formulation in which conspi
cuous consumption is viewed as a form of behavior characterized by par
ticular end results or outcomes. Consideration of each of these strand
s reveals major difficulties that prevent the construction of an opera
tional definition of conspicuous consumption and hence the extraction
of a workable theory from Veblen's discussion.
