The Maturity and Externality Effects

چکیده
This study investigates the relationship between information technology (IT) expenditures and national productivity based on a production estimation approach by using pooled time-series country-level data set for the period from 1992 to 2000. The results confirm the findings of earlier studies on country-level IT investment effect, showing IT to have significant and positive effects on national productivity growth. We find that IT maturity improves the positive effect of IT investment on national productivity growth and that the existence of IT externalities, through which spillovers of knowledge and innovation occur, may eventually lead to persistent long-term, national productivity growth.
