PAM200 – Section 9 David De Angelis – [email protected] Problem 10.17. When televisions can be freely imported at a price of P W = \$160, domestic producers will produce 20(160) = 3200 television sets. Domestic demand is 40,000 – 180*160 = 11,200 units. 3200 3600 7600 11,200 40,000 Q P 230 222 200 180 160 Domestic Supply A B J C F G K E P W + \$20 P W Demand When the import duty of \$20 is introduced, the effective price of importing televisions is \$180. At this price, domestic firms will supply 20(180) = 3600 televisions, and demand will be 40,000 – 180(180) = 7600. Domestic producer surplus will increase by area C = (180 – 160)(3200) + 0.5(180 – 160)(3600 – 3200) = 68,000. The tariff creates a deadweight equal to area F + K = 0.5(180 – 160)(3600 – 3200) + 0.5(180 – 160)(11,200 – 7600) = 40,000. An import duty of \$70 raises the effective import price to \$230. You can see from the graph that this is above the equilibrium price of \$200 that would prevail in the domestic market without any foreign trade. Thus, imposing such a high import duty is equivalent to banning trade in this industry altogether. The new price will be \$200 and the quantity demanded 4000.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
