Answer 1

A) False.

Export of good will reduce the consumer surplus and increase the producer surplus, but increase in producer surplus is higher than decrease in consumer surplus. So total economic surplus will increase.

B) False.

Importing a good will decrease the producer surplus but increase in consumer surplus will be higher. So overall economic welfare will increase.

C) False.

Imposition of tariff will reduce the overall economic welfare. Producer surplus will increase but consumer surplus will decrease.

D) False.

Overall economic welfare will decrease because consumer surplus will decrease more than increase in producer surplus.
