Get started for freeFrances sells pencils in the perfectly competitive pencil market. Her output per day and her total cost are shown in the following table: $$ \begin{array}{|c|c|} \hline \text { Output per Day } & \text { Total Cost } \\ \hline 0 & \$ 1.00 \\ \hline 1 & 2.50 \\ \hline 2 & 3.50 \\ \hline 3 & 4.20 \\ \hline 4 & 4.50 \\ \hline 5 & 5.20 \\ \hline 6 & 6.80 \\ \hline 7 & 8.70 \\ \hline 8 & 10.70 \\ \hline 9 & 13.00 \\ \hline \end{array} $$ a. If the current equilibrium price in the pencil market is \(\$ 1.80,\) how many pencils will Frances produce, what price will she charge, and how much profit (or loss) will she make? Draw a graph to illustrate your answer. Your graph should be clearly labeled and should include Frances's demand, \(A T C, A V C, M C,\) and \(M R\) curves; the price she is charging; the quantity she is producing; and the area representing her profit (or loss). b. Suppose the equilibrium price of pencils falls to \(\$ 1.00\). Now how many pencils will Frances produce, what price will she charge, and how much profit (or loss) will she make? Show your work. Draw a graph to illustrate this situation, using the instructions in part (a). c. Suppose the equilibrium price of pencils falls to \(\$ 0.25 .\) Now how many pencils will Frances produce, what price will she charge, and how much profit (or loss) will she make?
Draw a graph showing a firm that is operating at a loss in a perfectly competitive market. Be sure your graph includes the firm's demand curve, marginal revenue curve, marginal cost curve, average total cost curve, and average variable cost curve, and make sure to indicate the area representing the firm's loss.
Explain why at the level of output where the difference between TR and \(T C\) is at its maximum positive value, \(M R\) must equal \(M C\).
What are the three conditions for a market to be perfectly competitive?
A columnist for the Wall Street Journal discussed the fact that some firms were buying existing drilling operations in Canadian oil sands regions. These operations would not have been profitable to build from scratch but were profitable to operate given that they were already built because, as the columnist said, "The key is the distinction between fixed and variable costs. While the fixed investment in new oil sands projects is prohibitive, variable costs can be in the low \(\$ 20\) range per barrel." The columnist estimated that the fixed cost of a new oil sands drilling operation could be \(\$ 95\) per barrel. At the time the column was written, the price of oil was about \(\$ 50\) per barrel. a. Assuming that variable cost of an existing oil sands operation is \(\$ 20\) per barrel and the price of oil is \(\$ 50\) per barrel, how much were the companies selling these drilling operations losing per barrel? b. At a price of \(\$ 50\) per barrel, were the companies buying the existing drilling operations earning a profit of \(\$ 30\) per barrel? If not, explain what information we would need to calculate their profit.
