Price Control Overview
A price ceiling is a legal maximum price that can be charged for a good or service.
It is implemented to make goods or services more affordable for consumers.
Market Dynamics Under Price Ceiling
Supply and Demand Graph:
X-axis represents the quantity of apartments.
Y-axis represents the price (rent) of apartments.
Demand curve: downward sloping, indicating that as price decreases, quantity demanded increases.
Supply curve: upward sloping and inelastic in the short run; a significant price change doesn't lead to a large change in quantity supplied.
Reason for inelasticity: construction of new apartments takes time.
Setting a Price Ceiling
Equilibrium Price (p₀) and Quantity (q₀):
Equilibrium is where supply meets demand, establishing initial conditions before the price ceiling.
Price Ceiling Introduction (pₐ):
If set above p₀, it has no effect (market remains unchanged).
Price ceiling must be below p₀ to impact the market significantly.
Consequences of Price Ceiling Below Equilibrium:
Demand for apartments increases (Qd), while supply (Qs) decreases, creating a shortage (Qd > Qs).
Consumer Surplus vs. Producer Surplus
Consumer Surplus:
The benefit consumers receive when they pay less than what they are willing to pay for an apartment.
Increases for consumers who can rent at lower prices due to the price ceiling.
Producer Surplus:
The benefit producers receive when they sell at a higher price than the minimum they would accept.
Decreases as the price ceiling creates a lower selling price.
Deadweight Loss:
Represents the loss of economic efficiency when the equilibrium outcome is not achievable due to price controls.
Trades that would have occurred in a free market are lost, leading to a reduction in total surplus (producers and consumers).
Inefficiencies Created by Price Ceilings
Quality Reduction:
Lower incentive for landlords to maintain or improve properties due to capped rental prices.
Search Costs:
Increased difficulty and time to find available apartments due to the shortage in supply, leading to inefficient allocation of time and resources.
Misallocation of Resources:
Apartments may not go to those who value them most because allocation occurs at the controlled price rather than willingness to pay.
Overconsumption:
Example: Individuals might rent larger apartments than needed due to lower costs, preventing families that need larger spaces from accessing them.
Alternative Allocation Methods:
Wait times, side payments (bribes), and connections become more common as landlords differentiate among potential renters.
Long-Run Effects of Price Ceilings
In the long run, supply becomes more elastic as developers adjust strategies based on price controls.
Lower long-run supply will increase the severity of shortages over time as less housing is available in response to capped pricing.
Conclusion:
Price ceilings create both winners and losers in the market, often leading to unintended negative consequences.
Commonly seen in real-life housing markets, warranting further examination of potential alternatives.
