Underlying assumption of this diffusion matrix is that adoption costs of XML/EDI are assumed to be falling over time. Diffusion is assumed to be sequential rather than simultaneous. There are two reasons for this assumption. Potential users of a new technology may differ in a way that the expected returns from adoption are different due to firm size, market share, R&D expenditure, etc. Differences in prior believes [sic] about the ‘true’ profitability of a new technology [may result in different expected benefits from adoption and therefore in distinct adoption dates.] Adoption costs are assumed to be falling over time. Diffusion, i.e., sequential rather than simultaneous adoption by individual firms, may result for two reasons.

(i) Rank effects: the potential users differ with respect to the (expected) returns from adoption. The reasons arc differences in firm size, R&D expenditures, market

shares (see Karshenas and Stoneman, 1993, 1995), or even the prior beliefs about the profitability of a new technology (see Jensen, 1982).
