(30 points) In the above figure, suppose that the vertical axis indicates the price of cars while the horizontal axis indicates the quantity of cars. Suppose also that the price of cars before the tariff was $8,000, which is the world price of a small country. The price of cars went up to $9,000 after a tariff of 12.5%. Based on the information given and the above figure, illustrate the effects of a tariff and numerically calculate the (note: quantities are in thousands): 5. Numerically calculate the before and after tariff total economic loss. Notes: You may come up with different numbers depending how you calculate the losses (such as: (a) by using the before and after the levying of the tariff; or (b) by just eyeballing the welfare losses from the graph and doing the simple calculations.)
