Consider a market with the following supply and demand. (It may help to draw a graph for these questions.) P 5 6 7 8 9 10 11 12 13 14 QS 200 300 400 500 600 700 800 900 1000 1100 QD 800 750 700 650 600 550 500 450 400 350 If there is an external cost of $3, what is the efficient quantity? If there is an external benefit of $3, what is the efficient quantity? For the remaining questions assume that there is a $3 external COST. If the government wants to get the efficient quantity with a per/unit tax, how much should the tax be?

If the government wants to get the efficient quantity with a per/unit tax, how much should the tax be?
Now imagine that they use tradable allowances. If they cap the quantity at 400 what would the value of these allowance be in the market? (Assume the market is
What will they be worth if the quantity is capped at 500?
What if it is capped at 700?
