This paper compares the impact of information and communication technology (ICT) capital accumulation on output growth in Australia, Canada, Finland, France, Germany, Italy, Japan, the United Kingdom, and the United States. Over the past two decades, ICT contributed between 0.2 and 0.5 percentage point per year to economic growth, depending on the country. During the second half of the 1990s, this contribution rose to 0.3 to 0.9 percentage point per year. Despite differences between countries, the United States has not been alone in benefiting from the positive effects of ICT capital investment on economic growth nor was the United States the sole country to experience an acceleration of these effects. ICT diffusion and ICT usage play a key role and depend on the right framework conditions, not necessarily on the existence of a large ICT-producing sector.
