ICT Asset Prices : Marshaling Evidence into New Measures
This paper is a companion to our recent paper, "ICT Prices and ICT Services: What do they tell us about Productivity and Technology?" It provides the sources and methods used to construct national accounts-style price deflators for the major components of ICT investment--communications equipment, computer equipment, and software--that were presented and analyzed in that paper. The ICT equipment measures described herein were also used in Byrne, Fernald, and Reinsdorf (2016). This paper is a companion to our recent paper, "ICT Services and their Prices: What do they tell us about ...

The Increasing Deflationary Influence of Consumer Digital Access Services
Consumer digital access services—internet, mobile phone, cable TV, and streaming—accounted for over 2 percent of U.S. household consumption in 2018. We construct prices for these services using direct measures of volume (data transmitted, talk time, and hours of programming). Our price index fell 12 percent per year from 1988 to 2018 while official prices moved up modestly. Using our digital services index, we estimate total personal consumption expenditure (PCE) prices have risen nearly 1/2 percentage point slower than the official index since 2008. Importantly, the spread between ...

Accounting for Innovations in Consumer Digital Services: IT still matters
This paper develops a framework for measuring digital services in the face of ongoing innovations in the delivery of content to consumers. We capture what Brynjolfsson and Saunders (2009) call "free goods" as the capital services generated by connected consumers' stocks of IT digital goods; this service flow augments the existing measure of personal consumption in GDP. Its value is determined by the intensity with which households use their IT capital to consume content delivered over networks, and its volume depends on the quality of the IT capital. Consumers pay for delivery services, ...

Location, Location, Structure Type: Rent Divergence within Neighborhoods
Housing rents are a large share of household budgets and make a large contribution to overall inflation. Rent inflation rates for different types of housing units sometimes diverge, even in the same neighborhoods. We estimate during 2013 to 2016 apartment rents outpaced rents for detached housing in the United States by 0.76 percentage points annually after controlling for location effects. These rent dynamics imply a segmented housing market. They also suggest rent indexes need to be based on data structurally representative of their measurement objective. In particular, indexes based on ...

Prices for Communications Equipment: Rewriting the Record
Communication equipment plays as large a role in high-tech investment as computers, yet prices for communication equipment have not been studied as extensively as prices for computers and electronic components. Prices for satellites, cell phones, and the ground stations for these systems--important components of a nation's communications infrastructure--are difficult to locate in official statistics. This paper develops new price measures for 16 types of communications equipment from 1963 to 2009. Indexes for some (e.g., cellular phone systems) experience declines of 15-20 percent per year, ...

ICT Services and their Prices: What do they tell us about Productivity and Technology?
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 extend a multi-sector model due to Oulton (2012) to include ICT services (e.g., cloud services) and use it to calibrate the steady-state contribution of the ICT sector to growth in aggregate U.S. labor productivity. Because ICT technologies diffuse through the economy increasingly via purchases of cloud and data analytic services that are not fully accounted for in the standard narrative on ICT's contribution to economic growth, the ...
