In 1994, economists Lawrence Mishel and Jared Bernstein were first to point out the gap that was already opening up between pay (low) and productivity (high). Bernstein later served as Vice President Joe Biden’s chief economist and is now a senior fellow at the Center on Budget and Policy Priorities. Mishel is president of the Economic Policy Institute.
Now, Mishel has done the most careful study to date of what accounts for the productivity/pay gap. He wrote a blog post called “Understanding the wedge between productivity and median compensation growth” on April 26. He also has a longer article on the EPI website. And if that’s not enough, there’s a technical article by Mishel and Kar-Fai Gee of Canada’s Center for the Study of Living Standards published in that center’s International Productivity Monitor (PDF).
