Price Ceiling and Price Floor
A price ceiling is a legal maximum price (causing shortages) and a price floor a legal minimum price (causing surpluses); both are government interventions that distort markets.
A price ceiling below the market rate, like rent control or capped drug prices, can cause shortages and black markets. A price floor above the market rate, like the Minimum Support Price for crops or minimum wages, can create surpluses.
India uses both: MSP supports farmers (floor), while price caps on essential medicines and, at times, fuel protect consumers (ceiling). Each creates a deadweight loss and side effects, the classic trade-off between fairness and efficiency.
