| Unit 6: Market Failure and Role of Government |
| NOTE: Topic 2.9 -- The World Trade + Tariff Graph probably fits better in Unit 6 as this deals with Government Intervention in Different Market Structures. When this topic is located in Unit 1, it seems like a standalone lesson and is probably best remembered by students if it occurs in the last lesson in Principles of Microeconomics as it is a great review on CS, PS, DWL, etc. |

| Topic 2.9 International Trade and Public Policy World Trade Graph will be shown in Unit 6 when this website is completed. |
| On the next four links below (The Best Graphs), you can move the demand curve and show TR and then clear, TC and then clear, economic profit,and then clear. You can do the same thing with showing economic loss. You can show entry and exit. You can shift the supply curve and show the same things. You can show the Shut Down Rule. You can show the supply curve = MC of the individual firm and so on. You can do lots of things with these fiyr graphs. |
| Unit 4: Imperfect Competition (Monopoly, Monopolistic Competition, and Oligopoly |
| NOTE: Inside the link below, this is a chapter on Profit (Revenue - Costs). The interactive graphs can be enlarged for your PowerPoint or Google Slides presentation. |
| NOTE: Inside the link below, this is a chapter on Imperfect Competition Market Structures. You can enlarge the interactive material inside this chapter. |
| NOTE: Inside the 5 links below, are Perfect Competition graphs of a demand curve, consumer surplus, a supply curve which is the MC curve, producer surplus, and deadweight loss. These 5 links will help you get ready for all the calculations required when figuring the dollar-value of areas on a Monopoly graph. |
| NOTE: For the Monopoly vs. Perfect Competition Graph link below, set up the graph as a Monopoly and then drag the P line down to show the PC firms' market price (price takers). Perfectly Competitive Firms are allocatively efficient and produce the output where P = MC. Monopolies are allocatively inefficient and produce output where MR = MC. |
