Summary of Supply and Demand:
Supply and demand are fundamental economic concepts that describe how the market
determines prices and quantities of goods and services.
1. Demand: This refers to the quantity of a product or service that consumers are willing
and able to purchase at various price levels. According to the law of demand, as the
price of a product increases, the quantity demanded typically decreases, and vice versa.
Factors affecting demand include consumer preferences, income levels, the price of
related goods, and future expectations.
2. Supply: This represents the quantity of a product or service that producers are willing
and able to offer at different price points. The law of supply states that as the price of a
product increases, the quantity supplied also increases, and as prices fall, supply
decreases. Factors influencing supply include production costs, technology, the number
of sellers, and external conditions like weather for agricultural products.
3. Equilibrium: The point where supply and demand meet is called the market
equilibrium. At this price, the quantity supplied equals the quantity demanded, ensuring
market stability.
4. Shifts in Supply and Demand: Changes in factors other than price can shift the curves.
For instance:
○ An increase in consumer income may shift the demand curve to the right (higher
demand).
○ Improved technology can shift the supply curve to the right (greater supply at
each price).
5. Market Dynamics: When demand exceeds supply, it leads to a shortage and rising
prices. When supply exceeds demand, it causes a surplus and falling prices. These
dynamics drive market adjustments to restore equilibrium.
Understanding supply and demand is crucial for analyzing market behavior, setting prices, and
making informed economic decisions.
