Answer:
import
increases
decreases
unchanged
Step-by-step explanation:
If the world price of a good or service is below the equilibrium price of that good or service, it means that the world is more efficient in the production of that good. So, the country being analysed should import the good.
If the country imports the good, prices would fall. As a result, consumer surplus increases and the producer surplus decreases. total surplus remains unchanged
Consumer surplus is the difference between the willingness to pay of a consumer and the price of the good.
Producer surplus is the difference between the price of a good and the least price the seller is willing to sell the product
Total surplus = Consumer surplus + Producer surplus
