In a market economy, prices are determined by the interaction of supply and demand forces. The equilibrium price is the point where the quantity supplied by producers equals the quantity demanded by consumers. This concept is crucial for understanding resource allocation and market efficiency.
Supply represents the amount of a good or service that producers are willing and able to sell at various price levels. As prices rise, suppliers have a higher incentive to produce more, leading to an increase in quantity supplied. Demand represents the amount that consumers are willing and able to purchase at different price levels. Generally, as prices fall, the quantity demanded increases.
The market equilibrium occurs where the supply and demand curves intersect. At this equilibrium price, the quantity supplied equals the quantity demanded. If the price is above the equilibrium, there will be a surplus as producers supply more than consumers demand. Conversely, if the price is below equilibrium, there will be a shortage as demand exceeds supply.
Problem: In a market for widgets, the supply and demand schedules are given below. Find the equilibrium price and quantity.
| Price | Quantity Supplied | Quantity Demanded |
|---|---|---|
| $2 | 100 | 500 |
| $4 | 200 | 400 |
| $6 | 300 | 300 |
| $8 | 400 | 200 |
| $10 | 500 | 100 |
Solution:
The equilibrium price and quantity facilitate efficient resource allocation in a market. At this point, resources are allocated to their highest-valued use, and there is no shortage or surplus. Any deviation from equilibrium leads to inefficiencies, as resources are not being optimally utilized. Market forces tend to drive prices towards the equilibrium over time, promoting efficiency.
