The Laws of Supply and Demand

Market Equilibrium

                <p>The price of a good is determined where the <b>Supply Curve</b> meets the <b>Demand Curve</b>.</p>

Definitions:

                <ul>
                    <li><b>Law of Demand:</b> As price goes up, quantity demanded goes down (Inverse relationship).</li>
                    <li><b>Law of Supply:</b> As price goes up, quantity supplied goes up (Direct relationship).</li>
                </ul>
                <p><b>Exam Question:</b> What happens to the equilibrium price if consumer income rises? (Hint: Demand curve shifts right, Price increases).</p>

Price Elasticity of Demand (PED)

Understanding Elasticity

                <p>PED measures how sensitive consumers are to a price change. Formula: <code>% Change in QD / % Change in Price</code>.</p>
                <ul>
                    <li><b>Elastic (>1):</b> Consumers are sensitive (e.g., Luxury cars). A small price hike drops sales significantly.</li>
                    <li><b>Inelastic (<1):</b> Consumers don't care much (e.g., Insulin, Petrol). You buy it regardless of price.</li>
                </ul>
