Final answer:
If the lower limit falls below zero in economics, specifically in the context of price floors, it will have no effect on the equilibrium price.
Step-by-step explanation:
When dealing with the lower limit in economics, specifically in the context of price floors, if the lower limit falls below zero, it will have no effect on the equilibrium price. This is because an equilibrium price above a price floor will not be affected by that price floor. For example, if the equilibrium price is $10 and the price floor is set at $5, even if the lower limit is set at $0 or below, it will not impact the equilibrium price of $10.
