Answer:
The correct answer to the first fill in the blank is Decrease and to the second fill in the blank is Increase.
Explanation:
Consumer surplus can be defined as the difference between the current market price of the product and the price a consumer would be willing to pay for the product.
Producer surplus can be defined as the difference between current market price of the product and the least price that a producer would be willing accept for the product.
So if in a situation where without the trade taking place , the world price for a product is higher than the domestic price than when the trade takes place the consumer surplus would decrease and producer surplus would increase.
