In consumer theory, what does the 'Slutsky Equation' decompose the total effect of a price change on quantity demanded into?

💡 Solution & Explanation

The Slutsky equation in consumer theory mathematically breaks down the total change in consumer demand caused by a price change into a substitution effect and an income effect. The substitution effect captures the change in consumption resulting from a change in relative prices while keeping real purchasing power constant, whereas the income effect reflects the change due to the resulting alteration in real income.
