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 presente...

... IBM publishes performance scores for its systems whose usefulness is enhanced by two features: they are based on time to complete commonly used applications (rather than an artificial basket of instructions) and IBM is deeply committed to backward compatibility, making comparisons over time informative. Table 6 below shows benchmark scores, known as Large System Performance Reference ratios (LSPRs), for IBM's flagship mainframe models. 12 Our goal with this table is a sim- ple examination of the pace of advance of the frontier for mainframes in the "enterprise" (i.e., large business) market. ...

... Only prices on introduction are available and we do not have relative importance weights or an exhaustive set of model characteristics. 14 Table 6 shows that prices rose substantially less than performance in both periods. The price-performance ratio fell 31 percent per year for System/390 frontier models in the late 1990s, but by a more moderate 12 percent per year for zSeries models from 2005 to 2012. ...

The effects of temporal aggregation and choice of sampling frequency are of great interest in modeling the dynamics of asset price volatility. We show how the squared low-frequency returns can be expressed in terms of the temporal aggregation of a high-frequency series. Based on the theory of temporal aggregation, we provide the link between the sp...
This article presents a new model for valuing a credit default swap (CDS) contract that is affected by multiple credit risks of the buyer, seller and reference entity. We show that default dependency has a significant impact on asset pricing. In fact, correlated default risk is one of the most pervasive threats in financial markets. We also show th...

... Beginning with the November 2016 interim release, TED is released in two versions. e original version uses official price deflators to deflate nominal GDP and (whenever available) ICT investment (which include computer hardware and equipment, telecommunication equipment and computer soware and services), while the adjusted version uses alternative ICT investment goods deflators developed by Byrne, Fernald & Reinsdorf (2016); Byrne & Corrado (2017a, 2017b to deflate ICT investment. In the adjusted version, GDP deflators in three countries -United States, China and Japan -with a high share of ICT production and exports, are modified with this new ICT deflator. ...
... For computers and peripheral equipment, the authors incorporate indicators of price-performance trends in constructing their price index and find a downward difference from the official BEA index of 11 percentage points per year between 2010-15 (Byrne and Corrado, 2017b, Table 5). For software, Byrne and Corrado (2017b) construct an index using a refined version of the basic BEA approach (e.g., more granular structure for software products and more differentiated input cost measure). Overall, the alternative price index for ICT investment shows a rate of price change of -8% between 2004 and 2015, 5.9 percentage points below the official US price index. ...
... They base their estimates on the existing literature on high-tech price change and on their own price indexes for detailed products of the relevant US industries which they construct using a broad variety of statistical and industry sources. For communications equipment, the authors' price index declines at close to 10% per year between 2010-15, or 8 percentage points faster than the official price index(Byrne and Corrado 2017b, ...
