Per Tse (2025) a price floor is a legal minimum on the price at which a good can be sold. It is a restriction set in place by governments on prices. It must be binding to be effective (set above equilibrium price). This is the opposite to a price ceiling.
A price floor can be binding and not binding:
A binding price floor is set above equilibrium price, causing a surplus.
A price floor that is not binding is set below equilibrium price, having no effect on the market.
Per Segal (2025), a price floor is also know as a price support.
An example includes minimum wages: its purpose is to provide employees with an income that is enough to afford basic standard of living.
Another example per Segal (2025) is governments imposing floors on agricultural crops and products to mitigate the effects of price volatility (at a time of low prices) for the goods they produce, due to factors outside of their control.
