A.
Hicksian demand
Hicksian demand is a concept in microeconomics that describes how a consumer’s demand for goods changes when prices vary while holding utility (satisfaction) constant, often used in welfare and consumer theory.
-
B.
The Theory and Measurement of Demand
The Theory and Measurement of Demand is a foundational economics book by Henry Schultz that rigorously develops statistical and mathematical methods for estimating consumer demand.

C.
Hotelling’s lemma
Hotelling’s lemma is a result in microeconomics that links a firm’s profit function to its supply and factor demand functions via partial derivatives.

D.
Frisch elasticity of labor supply
The Frisch elasticity of labor supply is an economic measure that captures how responsive individuals’ labor supply is to changes in wages when their expected lifetime wealth is held constant.
