# 8.2 How perfectly competitive firms make output decisions  (Page 5/28)

 Page 5 / 28

It can be calculated as:

Or, it can be calculated as:

Now consider [link] (b), where the price has fallen to $3.00 for a pack of frozen raspberries. Again, the perfectly competitive firm will choose the level of output where Price = MR = MC, but in this case, the quantity produced will be 70. At this price and output level, where the marginal cost curve is crossing the average cost curve, the price received by the firm is exactly equal to its average cost of production. The farm’s total revenue at this price will be shown by the large shaded rectangle from the origin over to a quantity of 70 packs (the base) up to point E (the height), over to the price of$3, and back to the origin. The average cost of producing 70 packs is shown by point C’. Total costs will be the quantity of 70 times the average cost of $3.00, which is shown by the area of the rectangle from the origin to a quantity of 70, up to point E, over to the vertical axis and down to the origin. It should be clear from that the rectangles for total revenue and total cost are the same. Thus, the firm is making zero profit. The calculations are as follows: Or, it can be calculated as: In [link] (c), the market price has fallen still further to$2.00 for a pack of frozen raspberries. At this price, marginal revenue intersects marginal cost at a quantity of 50. The farm’s total revenue at this price will be shown by the large shaded rectangle from the origin over to a quantity of 50 packs (the base) up to point E” (the height), over to the price of $2, and back to the origin. The average cost of producing 50 packs is shown by point C” or about$3.30. Total costs will be the quantity of 50 times the average cost of \$3.30, which is shown by the area of the rectangle from the origin to a quantity of 50, up to point C”, over to the vertical axis and down to the origin. It should be clear from examining the two rectangles that total revenue is less than total cost. Thus, the firm is losing money and the loss (or negative profit) will be the rose-shaded rectangle.

The calculations are:

Or:

If the market price received by a perfectly competitive firm leads it to produce at a quantity where the price is greater than average cost, the firm will earn profits. If the price received by the firm causes it to produce at a quantity where price equals average cost, which occurs at the minimum point of the AC curve, then the firm earns zero profits. Finally, if the price received by the firm leads it to produce at a quantity where the price is less than average cost, the firm will earn losses. This is summarized in [link] .

If... Then...
Price>ATC Firm earns an economic profit
Price = ATC Firm earns zero economic profit
Price<ATC Firm earns a loss

what is opportunity cost?
Humphrey
Opportunity cost is the want sacrificed to satisfy another want.
Joseph
opportunity cost is a forgone alternative, example if a consumer wants to buy a book Nd a pen but he does not have the money for both then he drops the pen Nd buys the book..... so the pen that he dropped Is the opportunity cost
