Industrial production and capacity utilization: the 2004 annual revision
In late 2004, the Board of Governors of the Federal Reserve issued revisions to its index of industrial production (IP) and the related measures of capacity and capacity utilization for the period from January 1972 to November 2004. Overall, the changes to total industrial production were small. ; Measured from the fourth quarter of 2002 to the third quarter of 2004, industrial output is reported to have increased a little less than shown previously. Production expanded more slowly in 2000 than earlier estimates indicated, whereas the contraction in 2001 was a little less steep. The rise in ...

Valuing “free” media across countries in GDP
?Free? consumer entertainment and information from the Internet, largely supported by advertising revenues, has had a major impact on consumer behavior. Some economists believe that measured gross domestic product (GDP) growth since 2000 is too low because it excludes online entertainment (Brynjolfsson and Oh 2012; Ito 2013). Similar large effects on consumers occurred with the arrival of free radio and television entertainment. We provide an experimental methodology that uses previously established GDP measurement procedures to value advertising-supported entertainment around the world. The ...

Accounting for Growth in the Age of the Internet The Importance of Output-Saving Technical Change
We extend the conventional Solow growth accounting model to allow innovation to affect consumer welfare directly. Our model is based on Lancaster?s New Approach to Consumer Theory, in which there is a separate ?consumption technology? that transforms the produced goods, measured at production cost, into utility. This technology can shift over time, allowing consumers to make more efficient use of each dollar of income. This is ?output-saving? technical change, in contrast to the Solow TFP ?resource-saving? technical change. One implication of our model is that living standards can rise at a ...

Reconciled Estimates of Monthly GDP in the US
In the US, income and expenditure-side estimates of GDP (GDPI and GDPE) measure "true" GDP with error and are available at a quarterly frequency. Methods exist for using these proxies to produce reconciled quarterly estimates of true GDP. In this paper, we extend these methods to provide reconciled historical true GDP estimates at a monthly frequency. We do this using a Bayesian mixed frequency vector autoregression (MF-VAR) involving GDPE, GDPI, unobserved true GDP, and monthly indicators of short-term economic activity. Our MF-VAR imposes restrictions that reflect a measurement-error ...

Economic Activity by Race
We observe empirical differences between races across various macroeconomic variables for the White, Black, Asian, and Hispanic populations in the U.S. For instance, the Black unemployment rate in the U.S. is more often than not double the White unemployment rate. In this paper, I treat nine macroeconomic variables as noisy indicators of economic activity and estimate an index that measures the economic activity of racial demographic groups in the U.S., called Economic Activity by Race (EAR). The noise of the indicators motivates the use of Kalman filter estimation to extract a common ...

Communicating Data Uncertainty: Multi-Wave Experimental Evidence for UK GDP
Economic statistics are commonly published without any explicit indication of their uncertainty. To assess if and how the UK public interprets and understands data uncertainty, we conduct two waves of a randomized controlled online experiment. A control group is presented with the headline point estimate of GDP, as emphasized by the statistical office. Treatment groups are then presented with alternative qualitative and quantitative communications of GDP data uncertainty. We find that most of the public understands that uncertainty is inherent in official GDP numbers. But communicating ...

Newer need not be better: evaluating the Penn World Tables and the World Development Indicators using nighttime lights
Nighttime lights data are a measure of economic activity whose measurement error is plausibly independent of the errors of most conventional indicators. Therefore, we can use nighttime lights as an independent benchmark to assess existing measures of economic activity (Pinkovskiy and Sala-i-Martin 2016). We employ this insight to find out which vintages of the Penn World Tables (PWT) and of the World Development Indicators (WDI) better estimate true income per capita. We find that revisions of the PWT do not necessarily dominate their predecessors in terms of explaining nighttime lights (and ...

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 ...

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 ...

Aggregate Output Measurements: A Common Trend Approach
We analyze a model for N different measurements of a persistent latent time series when measurement errors are mean-reverting, which implies a common trend among measurements. We study the consequences of overdifferencing, finding potentially large biases in maximum likelihood estimators of the dynamics parameters and reductions in the precision of smoothed estimates of the latent variable, especially for multiperiod objects such as quinquennial growth rates. We also develop an R2 measure of common trend observability that determines the severity of misspecification. Finally, we apply our ...
