Assume that the following conditions exist for a perfectly competitive firm: price = $10, current output = 100 units/hour, atc at current output = $9.00, avc at current output = $8.00 and mc at current output = $8.00. a. is the firm earning any economic profit currently? how much is its profit or loss? b. is the firm maximizing its economic profit? how do you know? what should the firm do to maximize profit? should it increase or decrease output? c. given your answers in part b, how will the market adjust to reach long-run equilibrium? what will happen to the economic profit in the long-run? include appropriate graphs for the market and the typical firm in your explanation.
