Junior economists Diane Foreman and Les Harlan are discussing the concepts of aggregate hours and real wage rates and how they relate to real GDP. They state the following: Foreman: Aggregate hours are a more accurate measure of total labor input than the number of people employed. Aggregate hours tend to be positively correlated with real GDP growth. Harlan: Real wage rates have not increased as much over time as the productivity of labor, but that is largely because a greater share of labor compensation now comes in the form of employer-paid benefits.
