Study Notes
The Demand Curve
- A demand curve graphically represents the quantity of a good or service that consumers are willing to buy at various prices.
- Typically slopes downward, indicating that as prices decrease, demand increases.
- Price is plotted on the vertical axis and quantity demanded on the horizontal axis.
- Each good or service possesses a distinct demand curve, reflecting its unique consumption behaviors.
Oil Demand as an Example
- At a high price of $55 per barrel, demand for oil may be limited to five million barrels.
- When the price drops to 20perbarrel,demandcanescalateto25millionbarrels,andfurtherdeclineto20 per barrel, demand can escalate to 25 million barrels, and further decline to 20perbarrel,demandcanescalateto25millionbarrels,andfurtherdeclineto5 per barrel can see demand rise to 50 million barrels.
- Oil's diverse applications contribute to this demand variability, including both high-value uses (e.g., jet fuel) and low-value uses (e.g., gasoline, plastic).
Consumer Behavior with Price Changes
- Consumers react to price changes based on the utility of products; high prices result in reduced quantities demanded as people seek substitutes or economize.
- Low-value uses see a higher demand when oil prices drop, as alternatives are less appealing.
- For high-value uses with fewer substitutes (e.g., aviation fuel), demand remains relatively stable despite price increases since alternatives are limited.
Economic Implications
- The demand curve illustrates consumer decision-making; as prices rise, only those who value the good or service the most continue purchasing.
- Factors influencing demand include the availability of substitutes, the perceived value of goods, and the overall economic condition affecting consumption habits.
- Understanding the demand curve is essential for grasping concepts of supply, equilibrium price, and quantity in economics.
