Assume the nation of Australia is “small,” unable to influence world price, Its
demand and supply schedules for TVs are shown in Table. Using graph paper,
plot the demand and supply schedules on the same graph.
a. Under free-trade conditions, suppose Australia imports TVs at a price of $100
each.
(1)How many TVs will be produced, consumed, and
(2)Calculate the dollar value of Australian consumer’s surplus
and producer’s surplus.
b. To protect its producers from foreign competition, suppose the Australian
government levies a specific tariff of $100 on TV imported.
(1) Determine and show graphically the effects of the tariff on the price of TVs in
Australia, the quantity of TVs supplied by Australian producers, the quantity of
TVs demanded by Australian consumers, and the volume of trade.
(2) Calculate the effect on Australian consumer’s surplus and supplier’s surplus
due to the tariff-induced increase in the price of TVs.
(3) Calculate the value of the tariff’s revenue effects,redistribution effect and
protective effect and consumption effect.
(4) What is the amount of deadweight loss imposed on the Australian economy by
the tariff?
Suppose that $80 of imported wool goes into the domestic production of a suit.

(1) What is the relative price of cheese (the price of cheese in terms of wine)
