Slutsky Equation
The Slutsky equation, derived by Russian economist Eugen Slutsky in 1915, is a fundamental identity in microeconomics that decomposes the total change in demand for a good into two effects: the substitution effect and the income effect. Formalizing John Hicks' later interpretation, it provides the mathematical foundation for understanding consumer response to price changes and for distinguishing welfare-relevant demand responses.
