Average cost curves (except for average fixed cost) tend to be U-shaped, decreasing and then increasing. Marginal cost curves have the same shape, though this may be harder to see since most of the marginal cost curve is increasing. Why do you think that average and marginal cost curves have the same general shape?

Fixed costs are \(\$ 30 .\) Fill in Table 7.16 for total cost, average variable cost, average total cost, and marginal cost. $$\begin{array}{llllccc} \hline \text { Quantity } & \begin{array}{l} \text { Variable } \\ \text { cost } \end{array} & \begin{array}{l} \text { Fixed } \\ \text { cost } \end{array} & \begin{array}{l} \text { Total } \\ \text { cost } \end{array} & \begin{array}{c} \text { Average Variable } \\ \text { cost } \end{array} & \begin{array}{c} \text { Average Total } \\ \text { cost } \end{array} & \begin{array}{c} \text { Marginal } \\ \text { cost } \end{array} \\ \hline 0 & 0 & \$ 30 & & & & \\ \hline 1 & \$ 10 & \$ 30 & & & & \\ \hline 2 & \$ 25 & \$ 30 & & & & \\ \hline 3 & \$ 45 & \$ 30 & & & & \\ \hline 4 & \$ 70 & \$ 30 & & & & \\ \hline 5 & \$ 100 & \$ 30 & & & & \\ \hline 6 & \$ 135 & \$ 30 & & & & \\ \hline \end{array}$$
Automobile manufacturing is an industry subject to significant economies of scale. Suppose there are four domestic auto manufacturers, but the demand for domestic autos is no more than 2.5 times the quantity produced at the bottom of the long-run average cost curve. What do you expect will happen to the domestic auto industry in the long run?
