Many studies based on the production function approach have reported the positive impact of IT capital on economic performance. Yet, the reverse impact has often been reported in the information systems literature. To examine if these results at the country level are conflicting or
complementing with each other, we use the Granger causality test that allows the analysis of bidirectional causality with country-level data from 1992 to 2007. The results in general reveal that economic performance causes IT investment. By partitioning the sample period by 2000 (the dot-com bubble burst), we find unidirectional causality from economic performance to IT investment in pre-2000 while we find unidirectional causality from IT investment to economic performance in post-2000. The implication for managers is that it is possible to forecast IT investment by the analysis of past economic growth in all countries. Since 2000 networked IT by Internet could cause country-level economic performance in most countries.
