Final answer:
A tariff increase shifts the supply curve upward, changing the equilibrium price and quantity, which affects consumer surplus, producer surplus, and government surplus, leading to an efficiency loss.
Step-by-step explanation:
A student has asked about the effects of implementing a tariff of 2 dollars on an internationally traded good with a domestic demand of D = 24-2p and a domestic supply of s = 2p, where the world price is 2 dollars. To analyze the effects of the tariff, we would add the tariff to the world price, shifting the supply curve upward by the amount of the tariff. We would then re-evaluate the equilibrium, consumer surplus, producer surplus, and government surplus with the new supply curve.
The new price after the tariff would be higher, reducing consumer surplus, increasing producer surplus, and creating a government surplus equal to the tariff revenue. However, it would also lead to an efficiency loss or deadweight loss, which would be depicted in a supply and demand diagram as the areas of lost consumer and producer surplus due to the tariff.
To complete the table with computed values for CS, PS, and GS with the world price and tariff, we would need to calculate the areas of these surpluses on the graph pre- and post-tariff. The exact calculation of the efficiency loss requires more information or the ability to draw and measure the areas on the graph.
