4.2:
Surplus and Shortages
Market equilibrium is a balance between the quantities of goods supplied and demanded. When this balance is disrupted, shortages or surpluses occur.
A shortage arises when the quantity demanded exceeds the quantity supplied at a given price.
For instance, consider a scenario where sugar is priced at four hundred dollars per metric ton. Here, the quantity demanded exceeds the quantity supplied, leading to a shortage.
During shortages, sellers realize they could have charged more, while buyers acknowledge a willingness to pay higher prices.
Conversely, a surplus happens when the quantity supplied exceeds the quantity demanded at a specific price.
If sugar is priced at eight hundred dollars per metric ton, a surplus occurs.
Here, sellers struggle to sell their stock, and buyers find the price too high.
However, market dynamics naturally correct these imbalances driven by the principles of supply and demand.
During shortages, suppliers increase prices and the quantity supplied, which naturally reduces the quantity demanded.
In surpluses, sellers decrease prices and the quantity supplied. As a result, the quantity demanded increases.
4.2 Surplus and Shortages
Market Equilibrium occurs when the quantity of goods or services supplied by producers equals the quantity consumers are willing to purchase at a specific price. This equilibrium represents a state of balance in the market. However, this delicate balance can be disrupted by changes in market conditions, leading to either shortages or surpluses.
Shortages happen when the quantity demanded outstrips the quantity supplied at current prices, leading to increased prices. An example is the often-seen rush for gasoline before a major storm, where demand spikes unexpectedly.
Surpluses occur when the quantity supplied exceeds the quantity demanded at current prices, causing prices to drop. Consider the example of smartphone manufacturers overestimating demand for a new model, resulting in excess inventory.
In shortages, producers raise prices and increase the quantity supplied, eventually lowering the quantity demanded to a balanced state. During surpluses, producers cut prices and reduce the quantity supplied, making the product more affordable and boosting demand until equilibrium is reached.
The law of supply and demand governs these adjustments, ensuring that markets self-regulate over time to restore balance.
