Substitution and Income Effects

The substitution effect and income effect are two concepts used in economics to explain how changes in prices or income affect consumer behavior.

Substitution Effect:
The substitution effect occurs when the price of a good or service changes, causing consumers to switch to a substitute product that is now relatively cheaper. For example, if the price of coffee increases, consumers may switch to tea, which is now a relatively cheaper alternative.

Income Effect:
The income effect occurs when a change in income affects the purchasing power of consumers. If income increases, consumers can afford to buy more of a good or service, which leads to an increase in demand. Conversely, if income decreases, consumers may need to cut back on their spending, leading to a decrease in demand.

Both the substitution effect and income effect can have an impact on the overall demand for a product, and understanding these effects is important for businesses and policymakers when making decisions about pricing and taxation.
