Question

Demand is inversely related to price. Explain.

Answer 1

There is an inverse relationship between price and quantity demanded because higher prices diminish a consumer’s purchasing power (the income effect) while making other products appear more appealing (the substitution effect). Furthermore, as customers buy more of a thing, they experience less enjoyment from each additional unit, leaving them only inclined to buy more if the price falls (reducing marginal utility).

This fundamental concept, known as the Law of Demand, is pushed by three primary human behaviors:

1. Income Effect: When the price of a product rises, you can buy less of it while your overall income remains constant. This drop in purchasing power naturally leads to a decrease in demand.
2. Substitution Effect: If the price of one item rises, customers will switch to cheaper alternatives. For example, if the price of a branded beverage rises, customers may switch to a cheaper store-brand version.
3. Diminishing Marginal Utility: The more of a specific good you consume, the less enjoyment (or utility) you derive from each extra unit. Because the added value to you reduces, you will only buy more if the seller lowers the price.
