1. While the rate has fluctuated with recession, over longer periods it has been remarkably steady. In fact, in 1957, the economist Nicholas Kaldor summarized what was known about economic growth at the time in a classic article: “A Model of Economic Growth,”
Economic Journal
67, no. 268 (1957): 591–624. His observations, including the relatively constant growth rates of key variables, such as wage growth and the amount of capital per worker, came to be known as the “Kaldor Facts.”

12. This is consistent with a similar analysis by Oliner and Sichel (2002), who wrote, “both the use of information technology and the efficiency gains associated with the production of information technology were central factors in [the productivity] resurgence.” Oliner, Sichel, and Stiroh (2007) also found that IT was a key factor in this resurgence. Dale Jorgenson, Mun Ho, and Kevin Stiroh, “Will the U.S. Productivity Resurgence Continue?” Federal Reserve Bank of New York: Current Issues in Economics and Finance, December 2004, http://www.newyorkfed.org/research/current_issues/ci10-13/ci10-13.html.
Susan Housman, an economist at the Upjohn Institute has argued that the enormous productivity gains of the computer producing industries unfairly skew the productivity of the manufacturing sector (http://www.minneapolisfed.org/publications_papers/pub_display.cfm?id=4982). She says, “The computer industry is small—it only accounts for about 12 percent of manufacturing’s value added. But it has an outsized effect on manufacturing statistics. . . . But we find that without the computer industry, growth in manufacturing real value added falls by two-thirds and productivity growth falls by almost half. It doesn’t look like a strong sector without computers.” However, we see the glass as half-full, and welcome the contribution of computers even as other sectors lag.

Journal of Productivity Analysis
, 36, no. 2 (2011): 159–75, especially table 5, which shows the total factor productivity growth was about ten times higher in IT-using sectors than in sectors that did not use IT extensively.

Similarly, Stanford University’s Nicholas Bloom, Harvard University’s Rafaela Sadun, and the London School of Economics’ John Van Reenen found that American firms were particularly adept at implementing management practices that maximized the value of IT, and this lead to measurable productivity improvements, as documented.

18. According to the U.S. Bureau of Labor Statistics, productivity growth averaged 2.4 percent between 2001 and 2010, 2.3 percent between 1991 and 2000, 1.5 percent between 1981 and 1990, and 1.7 percent between 1971 and 1980.

5. Cannibalization of SMS services by free over-the-top (OTT) service is estimated to cost telephone companies over $30 billion in 2013, according to the analyst group Ovum. Graeme Philipson, “Social Messaging to Cost Telcos $30 Billion in Lost SMS Revenues,”

In theory, the hardworking statisticians at the Bureau of Economic Analysis try to account for quality-adjusted price changes. In practice, this works for small changes but not for highly disruptive introductions of new products and services. What’s more, sometimes increases in GDP reflect declines in our well-being. For instance, an increase in crime might prompt more spending on burglar alarms, police services, and prisons. Every dollar spent on these activities increases GDP, but of course the nation would be better off with less crime and less need for this kind of spending.

7. Try the 1912 Sears catalog (p. 873), where it’s priced at just 72 cents; see http://archive.org/stream/catalogno12400sear#page/872/mode/2up.
8. It turns out that you get a slightly different answer depending on whether you try to replicate the “happiness” that you had in 1993 using the 2013 catalog, or replicate the happiness of the 2013 catalog using the 1993 catalog. Technically this is the difference between what economists call the Paasche and Laspeyres Price indexes. An alternative is to continually adjust the basket of goods being considered, which is the approach used in so-called chained price indexes. The choice of price index, while subtle, can lead to hundreds of billions of dollars in differences over time, as in the case of indexing Social Security payments for changes in the cost of living.
9. In principle, when the exact same good is available for a lower price, the nominal GDP would fall, but the real GDP would not, with the difference being reflected in the price index. In practice, changes in consumption like this are not picked up in changes in price indexes, and thus official numbers for both nominal and real GDP fall.
