Final answer:
To add rows for the equilibrium outcomes of different market structures for the price elasticity of demand when n=2, follow the steps in Lecture Notes 6-Part 2.
Step-by-step explanation:
To add rows corresponding to the equilibrium outcomes of different market structures for the price elasticity of demand when n=2, you need to follow the steps provided in Lecture Notes 6-Part 2. First, identify the equilibrium price and quantity without considering any external costs.
Then, consider the additional external costs and determine the new equilibrium price and quantity. Finally, add the equilibrium outcomes to the summary table.
