The following graph represents a monopolistically competitive firm in long-run equilibrium.
Place the black point (cross sign) on the graph to indicate the short-run profit-maximizing price and quantity for this monopolistically competitive
company. Next, place the grey star on the graph to indicate the point where the LRAC reaches a minimum.

When oil prices increased 10 fold during the 1973 – 80 energy crisis, many oil companies made huge profits. During this energy crisis, Congress considered imposing an “excess profits” tax on oil companies. If you were in Congress, would you vote for such a tax? Do unexpected monopolistic profits serve any useful function in a market economy?

- If you have a graph showing a monopolistic competitive situation in which demand shifts to the left in the long run but your graph only shows the MR curve in the short run, how do you figure out where the long-run MR line should go on the graph?
