Her colleague, Harry Gomes, however, disagrees. According to Harry, some amount of inflation is unavoidable in a growing economy.

The purchasing power of nominal assets declines with an increase in the price level.

An article in the Wall Street Journal notes that "raising productivity in the long run is the most effective way to elevate standards of living." Source: Greg Ip, "Politicians Should Pay Heed to Productivity Problem," Wall Street Journal, July 22, 2015. The claim of this article is

continuous technological change.
Economist Robert Gordon of Northwestern University has argued that: My interpretation of the [information] revolution is that it is increasingly burdened by diminishing returns. The push to ever-smaller devices runs up against the fixed size of the human finger that must enter information on the device. Most of the innovations since 2000 have been directed to consumer enjoyment rather than business productivity, including video games, DVD players, and iPods. iPhones are nice, but the ability to reschedule business meetings and look up corporate documents while on the road already existed by 2003. Source: Robert J. Gordon, "U.S. Productivity Growth over the Past Century with a View of the Future, "National Bureau of Economic Research Working Paper 15834, March 2010. If Gordon's observations about the information revolution are correct, that implies
it will be difficult to sustain high growth rates in U.S. labor productivity in the future.
At the macro-economy level,

The American Trucking Association anticipates a shortage of trucker drivers in coming years as the number of retirees exceeds the number of new drivers who enter the profession. The number of train boxcars is also expected to fall by over 40 percent in coming years because federal regulations limit boxcars to 50 years of service and many currently in use will reach that limit by 2020. Lumber and paper producers that depend on boxcars for their shipments fear that they will have to depend more on trucks for transportation, which will cost as much as 20 percent more than shipping by rail. Sources: Lindsay Ellis and Laura Stevens, "International Paper Focuses on Improving Shipment Planning, Wall Street Journal, July 30, 2015; and Bob Tita, "Why Railroads Can't Keep Enough Boxcars in Service," Wall Street Journal, June 21, 2015. The reduction in the number of trucks and boxcars will
likely increase transportation costs and shift the short-run aggregate supply curve to the left.
Since 1950, expansions in the United States have become ________, while recessions have become ________.
longer; shorter
Shortly before the fall of the Soviet Union, the economist Gur Ofer of the Hebrew University of Jerusalem, wrote this: "The most outstanding characteristic of Soviet growth strategy is its consistent policy of very high rates of investment, leading to a rapid growth rate of [the] capital stock." Source: Gur Ofer, "Soviet Economic Growth, 1928-1985," Journal of Economic Literature, December 1987, p. 1,784. This turned out to be a very poor growth strategy because
there were diminishing returns to capital.
Knowledge capital is nonrival in the sense that
two people can use the same knowledge to develop and produce a product.
Typically, as an economy begins to emerge from a recessionary phase of the business cycle,
unemployment continues to rise.
Economists Mary Daly, Bart Hobijn, and Timothy Ni of the Federal Reserve Bank of San Francisco argue that "employers hesitate to reduce wages and workers are reluctant to accept wage cuts, even during recessions." Source: Mary C. Daly, Bart Hobijn, and Timothy Ni, "The Path of Wage Growth and Unemployment," Federal Reserve Bank of San Francisco Economic Letter, July 15, 2013. Employers are hesitant to cut workers' salaries because wage cuts
upset workers and lower their productivity.
