Long Run Average Cost (or LAC)

-Constant Returns to Scale

  • If the input is doubled, the output will double and average cost is constant at all the levels of output.

-Increasing Returns to Scale

  • If the input is doubled, outputs will double and average cost decreases at all the levels of output.

-Decreasing Returns to the Scale

  • If input is doubled, increase in output is less than twice and the average cost increases with the output.

-In the long run:

  • Firms experience increasing and decreasing returns to scale and therefore long run average cost is "U" shaped.

-Long run marginal cost(LMC) leads long run average cost(LAC):

  • If LMC < LAC, LAC will decrease
  • If LMC > LAC, LAC will increase
  • Thus, LMC = LAC at the minimum of LAC
