INSIGHT

Division Of Stock Is The Growth Hinge

  • Adam Smith makes the division of stock the analytic hinge for capital accumulation and growth in Book II.
  • He distinguishes stock for immediate consumption from stock employed as capital, arguing growth requires diverting some stock from consumption into productive investment.
INSIGHT

Human Abilities Count As Fixed Capital

  • Smith distinguishes circulating capital (money, inventory, provisions) from fixed capital (machines, buildings, land improvements, and acquired skills).
  • He explicitly treats acquired skills as fixed capital, an early formulation of human capital that predates Gary Becker.
INSIGHT

Money Is The Wheel Not The Meal

  • Smith treats money as part of circulating capital but insists it is not productive itself; it's the wheel that moves goods rather than creating value.
  • He argues national wealth is the productive resources and labor, not the stock of gold and silver, so money's role is facilitating exchange.
