Marshallian Demand Curve

The Marshallian demand curve shows how much of a good a consumer is willing to buy at different prices, assuming their income and preferences stay the same. When the price of the good drops, consumers typically want to buy more, and when the price rises, they buy less. This relationship helps economists understand consumer choices and how prices influence demand. It’s derived from the consumer’s goal—to maximize satisfaction or utility—by choosing the best combination of goods within their budget. Essentially, it maps the consumer’s optimal purchases across various prices.
