Current studies in the effects of ICTs on development consider the key variables that effect Gross Domestic Product growth. However it appears that there are a number of variables that affect this relationship over time. The same variable may be affected by growth while it also effects growth. An understanding of these relationships can enable a better understanding of the role of ICTs in development and how it acts as part of a larger development system. Further many existing studies examine the effects of ICT investments rather than the ways in which ICT is adopted and used. This paper considers the relationships that affect the ways in which ICT brings about economic growth. It considers how ICTs are adopted and used by considering the public policies and how they were implemented for two countries, Singapore and Malaysia. These countries have pursued public policies in ICT adoption and use but have very different outcomes. Following an analysis of time series data over about 30 years, we arrive at conclusions as to effectiveness of ICT in transforming an economy. Our findings suggest that there is a strong role for early coordinated intervention in markets to foster the growth and coordinated use of ICT.
