Consider Kellogg's production and price choices in the breakfast cereal industry when it is characterized by the price-leadership model.
Under this theory of oligopoly, all firms other than the dominant firm act as
of their marginal cost curves is their
curve.
The following graph shows the market demand curve and the horizontal sum of the marginal cost curves of all firms other than the dominant firm:

Given the information on the preceding graph, use the blue line (circle symbol) to graph the demand curve for the dominant firm (also known as the
residual demand curve) and the black line (plus symbol) to graph the marginal revenue curve for the dominant firm on the following graph. (Hint: The
slope of the marginal revenue curve is twice that of the demand curve since the demand curve is linear in this case.)

This graph also shows the dominant firm's marginal cost curve. Given that cost curve, as well as the demand and marginal revenue curves you
derived, the price of a box of cereal will be $
under the price-leadership model.
