The Slutsky decomposition clarifies how income and substitution effects combine to determine a consumer's response to a price change.

After reviewing the data, I emailed Slutsky to ask for clarification.

In many econometric proofs, Slutsky's theorem is used to justify that the sum and product of convergent estimators behave like the corresponding operations on their limits.

In the lecture, she used the Slutsky equation to decompose a consumer's response to a price change into substitution and income effects.
