A number of regional Internet electronic marketplaces (REMs) have failed or are floundering, partly due to the lack of proper evaluation of their costs and benefits. This paper uses a conceptual REM Success Model to examine the costs and benefits of a REM in Western Australia. The model has been derived from an extension to the Updated DeLone & McClean IS Success Model. The findings from the ca...
