A)A tariff will increase world price for domestic consumers or increase price of imported shirt.
Increase in world price lead to decrease in consumption of good by domestic consumers as a result consumer surplus decreases. So domestic consumers are worsen off by this decision.
On other hand , increase in world price ,lead to increase in quantity supplied by domestic supplier, as a result producer surplus increase.so domestic producers get benefited from this decision.
Due to tariff , government able to generate revenue for themselves,so they also get benefited from this.
B) Government put tariff on imports to protect the interest of domestic producers.
Because of lower world price, foreign producers get mostly the share of domestic market. As a result domestic producers get lower profit and couldn't grow much.
So to protect them , government put tariff on imports to make foreign good more costly as a result sales of domestic good increase and domestic producers get to increase their profit.
But due to tariff , consumer have to pay higher prices , as result quantity demanded decreases and consumer surplus falls. On other hand, government able to generate extra revenue.
C) Increase in tariff will decrease demand of imported good ,as a result demand of foreign currency decrease. Or supply of Australia dollar decrease. Because to buy foreign currency, Australia dollar is traded,so it supply is directly correlated with foreign currency demand.
Decrease in supply of Australia dollar will increase value of Australia dollar against foreign currency. So as a result exchange rate increases.
