Finally, assume that the equilibrium market price is $5 per Frisbee.
(a) How many Frisbees are being sold in equilibrium?
(b) How many (identical) firms are initially producing Frisbees?
(c) How much profit is the typical firm making?
(d) In view of the profits being made, more firms will want to get into Frisbee production. In the long run, these new firms will shift the market supply curve to the right and push the price down to average total cost, thereby…

If many firms can supply an input, then suppliers are likely to have the bargaining power to limit a firm's profits. O D. If only a few firms can supply an input, then markets will likely experience shortages because firms are unable to produce sufficient output. O E.
