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.

1. Consider market adjustment from the short-run to the long-run under a perfectly
competitive market. What will happen in the market if a typical firm in
the market is making economic profit or loss?
2. Use a set of two graphs, one graph for the market and the other graph for a firm,
to show the long-run equilibrium under a perfectly competitive market. What is
the level of economic profit for the firms in this case?
