Answer:
gain surplus from paying a lower price
Explanation:
An effective price ceiling will cause consumers to "gain surplus from paying a lower price."
This is based on the idea that an effective price ceiling usually leads to prices being below the equilibrium price or equates to a lower price.
At this point, the buyers demand more of the products, while the sellers have a lower incentive to produce more. And therefore, the quantity demanded will exceed the quantity supplied.
Hence, consumers gain excess (more demands) by paying a lower price.
