This paper reassesses the link between ICT prices, technology, and productivity. To understand how the ICT sector could come to the rescue of a whole economy, we introduce a simple model that sets out the steady-state contribution of the sector to the growth in U.S. labor productivity. The model extends Oulton (2012) to include ICT services and draws conclusions about the relationship between prices for ICT services and prices for the capital stocks (i.e., ICT assets) used to supply them. The currently available information on ICT asset prices and ICT services is put under a microscope, and official prices are found to substantially understate actual ICT price declines. And because ICT capital continues to grow and penetrate the economy—increasingly via cloud services which are not fully accounted for in the standard narrative on ICT's contribution to economic growth—the contribution of the sector to growth in output per hour going forward is calibrated to be substantially larger than it has been in the past.
