Atif Mian and Amir Sufi at House of Debt on a subject that has come up here many, many times:
The Most Important Economic Chart, by Atif Mian and Amir Sufi: If you must know only one fact about the U.S. economy, it should be this chart:
The chart shows that productivity, or output per hour of work, has quadrupled since 1947... This is a spectacular achievement...
The gains in productivity were quite widely shared from 1947 to 1980. ... However, what we want to focus on today is the remarkable separation in productivity and median real income since 1980. While the United States is producing twice as much per hour of work today compared to 1980, a small part of the gain in real income has gone to the bottom half of the income distribution. The gap between productivity and median real income is at an historic all-time high today.
So where are all of the gains in productivity going? Two places: First,... the share of profits has risen faster than wages. Second, the highest paid workers are getting a bigger share of the wages that go to labor. ...
It is not just about inequality... The widening gap between productivity and median income has serious implications for macroeconomic stability and financial crises. Our forthcoming book takes up these issues in more detail.
We will also discuss some of these issues in coming posts.
