The Rise and Fall of American Growth: The U.S. Standard of Living since the Civil War (The Princeton Economic History of the Western World Book 70)

Over the seven decades between 1870 and 1940, the real wage grew almost a full percentage point faster than productivity, 2.48 versus 1.51 percent per year. But after 1940, the relationship was reversed, with productivity growth of 2.25 percent outpacing real wage growth of 1.56 percent by a difference of 0.69 percentage points.
