Mark thoma verbaasde zich over de opsplitsing van de productiviteitsgroei in de VS in de laatste jaren, zoals Fernald dat deed
The four factors in the decomposition are:

  • Changes in the composition of the workforce (labor quality), weighted by labor's share of income
  • Changes in the amount and type of capital per hour that workers have to use (capital deepening), weighted by capital's share of income
  • Changes in the cyclical intensity of utilization of labor and capital resources (utilization)
  • Everything else—all the drivers of labor productivity growth that are not embodied in the other factors. This component is often called total factor productivity
de min voor capital deepening is vreemd, gebeurt eigenlijk nooit
