Price ceiling is an economic term that describes the situation in which the government imposes a legal maximum on the price of a good.
If the price ceiling is below the equilibrium price, the
price ceiling causes a shortage in the market. So, if the
equilibrium price is $40 or below, a price ceiling of $40 has no effect on the number of people attending musical
concerts. But, if the equilibrium price in the absence of price
controls is above $40 per ticket, then imposing a price ceiling of $40
will cause quantity demanded to exceed quantity supplied. This will result in a
shortage of tickets and a decrease in the number of people who attend
classical music concerts.
