The Relative Advantage of Electronic Channels:
A Multidimensional View
Vivek Choudhury and Elena Karahanna
Abstract
The Internet has the potential to fundamentally change the
structure of marketing channels, but only if consumers choose to
adopt electronic channels. Thus, this paper aims to develop a more
nuanced understanding of consumer channel choices. Specifically, it
contends that it is important to examine consumers’ intent to adopt
electronic channels, not as a monolithic decision, but as a choice
they make at each of four stages in the purchase process:
requirements determination, vendor selection, purchase, and
after-sales service. Innovation diffusion theory suggests that
consumers make adoption decisions based on their perceptions of the
relative advantage of the innovation. The relative advantage of
electronic channels is conceptualized as a multidimensional
construct involving a cumulative assessment of the perceived
relative merits of channels on three dimensions: convenience, trust,
and efficacy of information acquisition. Combining the
multidimensional nature of relative advantage with the multistage
purchase process, the central assertion, and intended contribution,
of this paper is to show that the relative advantage of
electronic channels, and the influence of each dimension of relative
advantage on the adoption of electronic channels, will vary across
the different stages of the purchase process.
Survey data were collected from faculty and staff at a large
university about their intention to use the web for auto insurance
transactions. The results provide support for the multidimensional
nature of relative advantage, although the emergent factors do not
align neatly with the hypothesized dimensions (convenience, trust,
and efficacy of information acquisition) or stages. Results of the
study support three conclusions. First, the dimensions along which
consumers assess relative advantage blend hypothesized dimensions
such as trust and convenience with stages of the purchase process.
Second, consumers consider the relative advantage of channels at two
distinct stages of the purchase process: gathering
information and executing the transaction. Third, different
dimensions of relative advantage are critical in predicting consumer
channel choice at each stage.
