What is Substitution Effect?

The substitution effect is the decrease in sales for a product that can be attributed to consumers switching to cheaper alternatives when its price rises. A product may lose market share for many reasons, but the substitution effect is purely a reflection of frugality. If a brand raises its price, some consumers will select a cheaper alternative. If beef prices rise, many consumers will eat more chicken.
Definition
The substitution effect refers to the phenomenon where consumers switch to cheaper alternatives when the price of a product increases, leading to a decrease in sales of the original product. This effect reflects consumers' frugal behavior in response to price changes. For example, if a brand raises its prices, some consumers may opt for cheaper substitutes.
Origin
The concept of the substitution effect originates from consumer behavior theory in economics, dating back to the late 19th and early 20th centuries. Economists developed this theory by studying consumer choices in response to price changes.
Categories and Features
The substitution effect can be categorized into direct and indirect substitution. Direct substitution occurs when consumers choose a lower-priced option within the same product category, such as choosing chicken when beef prices rise. Indirect substitution involves different categories of products, such as opting for public transportation instead of a private car. The main features of the substitution effect are price sensitivity and changes in consumer preferences.
Case Studies
A classic example is the oil crisis of the 1970s, when gasoline prices soared, leading consumers to purchase more fuel-efficient cars. Another example is the recent rise in beef prices, prompting many consumers to buy chicken or pork as substitutes.
Common Issues
Investors often overlook market trends and changes in consumer preferences when considering the substitution effect. Additionally, confusing the substitution effect with demand elasticity is a common issue. The substitution effect focuses on consumer choices in response to price changes, while demand elasticity involves the overall impact of price changes on demand quantity.
