(a) to demonstrate the effects of a tariff in this market.

c. Carefully identify the sources of the various changes in consumer and producer surplus that are brought about by the tariff in part (b).

d. Show how the deadweight losses brought about by the tariff in this case will depend on the elasticity of demand and the elasticities of supply of domestic and imported goods.
