Spider-Man 3 will come to this summer

Spider-Man 3 will come to this summer. From the economic way, we can see the film is artificially scarce goods, because it is an excludable and nontrivial in consumption. This kind of goods is nature monopoly goods, because the marginal cost is zero and the marginal benefit always more than marginal cost. “The first two adventures of Peter Parker grossed $403.7 million and $373.6 million in the U.S. respectively, according to figures from tracking firm Box Office Mojo.” so if people like to watch the film, it will get great benefit.
