Answer:
The correct answer is: supply; leftward.
Step-by-step explanation:
An import quota is a kind of trade restriction that limits the physical quantity of a good that can be imported on a country. In other words, an import quota reduces the equilibrium quantity supplied of imported goods.
A more restrictive import quota on Japanese video game systems will reduce the quantity of gaming systems imported. This reduction in the supply of video game systems will shift their supply curve to the left. The quantity of gaming systems will decline and their equilibrium price will increase.
