The primary problem created by price floors set above the equilibrium is excess supply, also known as a surplus.
Understanding Price Floors and Equilibrium
A price floor represents a minimum price legally mandated for a good or service in a market. For a price floor to genuinely impact the market and lead to problems, it must be established above the equilibrium price. The equilibrium price is the point where the quantity of a good that consumers are willing and able to buy precisely matches the quantity that producers are willing and able to sell in a free market.
The Problem: Excess Supply (Surpluses)
When a price floor is enforced above the market's natural equilibrium price, it disrupts the balance between supply and demand, leading directly to a surplus.
- Quantity Supplied Exceeds Quantity Demanded: At the higher, artificially imposed price, producers are incentivized to increase their production because they can sell their goods for more money per unit. This increased profitability encourages them to supply a larger quantity to the market. Conversely, consumers find the good more expensive than at equilibrium, leading them to demand less of it. The combined effect of increased supply and decreased demand at the higher price means that the amount of the good producers make available is significantly more than what consumers are willing or able to purchase.
- Accumulation of Unsold Goods: This fundamental mismatch—where quantity supplied will exceed quantity demanded—results in an excess supply or surplus. These are goods that have been produced but remain unsold because there isn't enough demand at the mandated price.
Key Impacts of Surpluses
The accumulation of excess supply due to a price floor has several detrimental consequences:
| Problematic Outcome | Description |
|---|---|
| Wasted Resources | The production of goods that are not purchased means that the resources (such as labor, raw materials, and capital) used to create them are not being allocated efficiently. These resources could have been used to produce other goods that consumers actually desire. |
| Storage Costs | Holding unsold inventory can lead to significant storage expenses for producers or, if the government intervenes, for taxpayers. These costs can include warehousing, refrigeration, and security, especially for large quantities. |
| Potential Spoilage | For perishable items (like agricultural products), a surplus can quickly lead to spoilage and complete waste if the goods cannot be sold or stored effectively before their expiration or deterioration. |
| Government Spending | To maintain the price floor and support producers, governments often have to step in and purchase the excess supply. This intervention can be very costly, burdening taxpayers and resulting in large stockpiles of goods that may never be consumed. |
| Market Inefficiency | The market operates inefficiently, as the price mechanism is prevented from adjusting to clear the market. This often leads to a deadweight loss, representing lost economic welfare due to the artificial price. |
Real-World Example
A prominent example of price floors leading to surpluses is found in agricultural price support programs. Historically, many countries have implemented price floors for staple crops such as corn, wheat, or dairy products. These measures are often intended to stabilize farmers' incomes. However, when these floors are set above the market equilibrium, farmers produce more than the market demands at that price. The resulting large surpluses often necessitate government intervention, where the government buys and stores the excess produce, sometimes even leading to its disposal, at considerable public expense.
