b. Next, graphically illustrate how, after the initial changes you illustrated in question 7,
the corn market and the representative firm would adjust back to long-run equilibrium.
Label any new curves and equilibrium values using a subscript 3. After all adjustments
have taken place, what has happened to the equilibrium market price, the number of
firms operating in the market, and the representative firm’s profits? Why?
Suppose a perfectly competitive firm, which is initially in long-run equilibrium
experiences a decrease in the wages it must pay its employees. In the short run, which
of the following will occur?
A) ATC will shift up and MC will shift down, causing the firm to incur a loss.
B) ATC will shift down and MC will shift up, causing the firm to earn a positive
economic profit.
C) ATC and MC will shift down, causing the firm to earn a positive economic profit.
D) ATC and MC will shift up, causing the firm to incur a loss.
