1. Assume you have a perfectly competitive market with two types of firms. The only difference between the two types of firms is that the minimum average cost at which firms of type A can produce is lower than the minimum average cost at which firms of type B can produce. a. Give a graphical example of what the individual long run supply functions of a type A firm and a type B firm may look like. Explain the shape in detail. b. Based on your example, what will the aggregate supply curve of a market with 2 firms, one type A and one type B, look like? Explain the shape in detail. c. Assume now that all potential firms are identical. Evaluate the impact of a demand shock on the long run equilibrium market price and firm numbers. You must use graphical analysis and explain in detail
