Monopolistic Competition

In this video I explore what monopolistic competition is with examples of it, characteristics required to achieve this, diagrams of it in the short-run and long-run. A supplementary booklet can be found below.


In this video I look at what is a monopoly? what characteristics does it have? Why might a firm want to be one? How does it do its pricing? What does a monopoly diagram look like? What efficiencies are associated with a monopoly? What are the costs and benefits to consumers? 

Also, there is a supporting booklet to the video attached below.
