This runs against conventional wisdom, so I'd like your thoughts.

Many pundits, politicians and economists claim that wages have fallen behind productivity gains over the last generation. This "decoupling" explains allegedly stagnant (or in some versions of the story, declining) middle-class incomes and is held out as a crisis of the market economy.
This story, though, is built on an illusion. There is no great decoupling of worker pay from productivity. Nor have workers' incomes stagnated over the past four decades.
The illusion is the result of two mistakes that are routinely made when pay is compared with productivity. First, the value of fringe benefitssuch as health insurance and pension contributionsis often excluded from calculations of worker pay. Because fringe benefits today make up a larger share of the typical employee's pay than they did 40 years ago (about 19% today compared with 10% back then), excluding them fosters the illusion that the workers' slice of the (bigger) pie is shrinking.
The second mistake is to use the Consumer Price Index (CPI) to adjust workers' pay for inflation while using a different measurefor example the GDP deflator, which converts the current prices of all domestically produced final goods and services into constant dollarsto adjust the value of economic output for inflation. But as Harvard's Martin Feldstein noted in a National Bureau of Economic Research paper in 2008, it is misleading to use different deflators. ...
Consider, for instance, that between 1970-2006 the CPI rose at an average annual rate of 4.3%, while the GDP deflator rose only 3.8%. Economists believe that such a difference arises because the CPI is especially prone to overestimate inflation. Therefore, much of the increase in the real purchasing power of workers' pay is mistakenly labeled by the CPI as mere inflation.
Mr. Feldstein and a number of other careful economistsincluding Richard Anderson of the St. Louis Federal Reserve Bank and Edward Lazear of the Stanford University Graduate School of Businesshave compared worker pay (including the value of fringe benefits) with productivity using a consistent adjustment for inflation. They move in tandem. And in a study last year, João Paulo Pessoa and John Van Reenen of the London School of Economics compared worker compensation and productivity in both the United States and the United Kingdom from 1972-2010. There was no decoupling in either country. ...
