The value relevance of enterprise resource planning information
Date of this Version
This paper examines whether ERP systems contribute to enterprise value. An ERP Value Relevance Model is developed and tested with data from 60 matched pairs of ERP–adopter/ non–adopter firms. Two classes of tests are designed: performance relevance and value relevance. Tests of performance relevance show ERP–adopter firms do not achieve significant positive abnormal earnings until year four of the five–year test period. Tests of value relevance show the market responds significantly to ERP adoption in year two only. This early response in the year following the year of adoption suggests a significant early market expectation of these systems. However, this expectation does not appear to translate into a sustained contribution to firm value. The paper contributes to the question of enterprise value of ERP adoption. The method presented can be adapted to test the value relevance of other innovations in management and technology.
