Acceptance of E-reverse auction use: an empirical comparison of models

This study aims to understand factors affecting e-reverse auction usage in companies by comparing three models: TAM, TPB and an integrative model (integration of TAM and TPB). Using LISREL 8.54, data collected from 156 employees working in the procurement department of companies in 40 different countries were used to test the models. Results indicated that, TPB may be more appropriate than the TAM and integrative model for explaining behavioral intention to use e-reverse auction. Behavioral intention to use is explained-by only attitude towards use in TAM; by subjective norms, perceived behavioral control and attitude towards use in both TPB and the integrated model.
