  1. What can a firm do in the short run?
    • 1.earn positive economic profits
    • 2.earn zero economic profits
    • 3.suffer economic losses but continuing to operate to reduce or minimize those losses 4.shut down and bear losses just equal to fixed costs.
  2. In a PC firm, is it a profit or loss is price is below ATC?
    an economic loss
  3. For a PC firm, should a company stay in business if price is below AVC?
    No
  4. The short run supply curve for a PC firm is also know as the __________.
    A. marginal revenue curve
    B. demand curve
    C. price curve
    D. marginal cost curve
    D. marginal cost curve
    (this multiple choice question has been scrambled)
  5. In the short run, a firm should shut down if _____.
    P< AVC
  6. Firms earning a negative profit will eventually _____.
    leave the market
  7. Firms are going to _______ if everyone has a positive profit.
    enter
  8. There will no be action (no entry and exit into the market) if there is _________ profit.
    zero (normal profit)
  9. In the short run, perfectly competitive firms can earn ____________.
    Positive or negative profits
  10. In the long run all PC firms MUST earn________.
    zero profit
  11. Total revenue equals_______.
    Price x Quantity
  12. If PC firms are making positive profits, in the long run firms will enter this industry. This shifts the supply curve ________ and ______ the prices.
    out, lowers
  13. PC firms earning a positive profit will continue to expand as long as there are ______________.
    economies of scale
  14. True or False: In the long run all firms can make positive profits?
    False
  15. In the short run when a PC firm is making a negative profit, they will leave the market in the long run. This shifts the supply curve _____ and ______ the prices.
    back, increases
  16. Know this equation for the tests
    P* = SRMC = SRAC = LRAC
  17. In the long run, PC firms operate at the _________ point of the LRAC curve.
    minimum
  18. In the short run when demand increases, what happens to PC firms' revenues? How do other firms respond? In response, what happens to the supply curve? Then, what happens to prices in the long run?
    The PC firms raise their prices, and therefore gain more profits. Other firms see the positive profits and enter in the long run. This causes the supply curve to shift out (more products). More products in the industry causes the prices to fall.
  19. Suppose the industry we just saw starts out in LR equilibrium at P=$5. What would happen in the short run if demand shifted back and price fell below $5?
    It depends on whether price falls below average variable cost.

    A. less

    Why? Think about coach purses. There are not many substitutes for these products, so more people are willing to pay a high price.
