Information and Communication Technologies in a Multi-Sector Endogenous Growth Model

This paper investigates the growth impact of Information and Communication Technologies (ICT) in an economy consisting of three sectors: ICT-producing, ICT-using, and non-ICT-using. The ICT progress causes falling prices of the consumption and intermediates produced by the ICT-using sector, providing incentives for investment in the sectors using them. Therefore, the non-ICT-using sector benefits indirectly from ICT, while households utility increases. The magnitude of the growth transmission mechanism relies on the ICT-using sector production shares. Aggregate economy is on a constant growth path, where growth rates differ across sectors. The model predictions are broadly consistent with the U.S. growth experience
