Most of the studies on the consequences of information and communication technology (ICT) have been focused on US aggregate data. In contrast to these studies, this paper empirically assesses the industrial effect of ICT investment on three key variables – real output, employment, and labour productivity – in some European Union-15 (EU-15) countries and the USA using panel-vector autoregression models. An increase in ICT investment is positive for the economies of these countries, giving rise to larger growth in real output, employment, and labour productivity at the industrial level. The pattern of responses to changes in ICT investment is quantitatively diverse across most of the EU-15 countries studied and in the two types of industries considered (i.e. ICT-intensive and less intensive industries). Moreover, the positive impact on labour productivity in ICT-intensive industries is larger after the mid-1990s, with the USA being the most positively affected country.
