David Blanchford of Dartmouth College and Adam Posen of the Peterson Institute of International Economics argue in a recent paper that the true indicator of unemployment in this economy -with a low participation rate and millions dropping out of the labor market unable to find work- is the wage growth. This is particularly true with the U.S. Labor Department report of 288,000 new jobs in 2014 and a 6.3% unemployment rate, yet wages flat for March and April 2014, and no improvement in the participation rate. Blanchford says one should look at the wage growth and consider the rest to be noise. The Yellen Fed is looking closely at the participation rate.
