c) Explain why Average Variable Cost and Marginal Cost can fall initially,
but eventually rise.
d) If Fixed costs were to fall, how will that affect AFC, AVC, ATC, and
MC? Explain the intuition.
e) Explain the difference between the short-run and the long-run. How
does this concept relate to the data presented here?
f) Given a price of $145, how much of Good X will the perfectly competitive firm produce? How
much profit will the firm earn?
g) In the long run, if the market for X was made up of firms with the same cost structure,
what do you roughly expect the Perfect Competition market clearing price and per-firm
quantity to be? How much profit will they earn?
h) Given the following demand schedule, how much X would a monopoly produce, given the cost
table above? What price will they charge? How much profit will the firm earn?
