The substitution effect from the profit function in consumption: Expressions from the marshallian, hicksian, and frischian demand functions

Abstract

In the context of the optimizing behaviour assumption of individuals (Becker, 1976), three types of demand functions appear: Marshallian, Hicksian, and Frischian functions (Sproule, 2013). The Substitution Effect (SE) is a relevant concept, with our short paper developing two alternative theoretical expressions, specifically focusing on the Profit Function in Consumption and the Frischian functions. I address the fact that these demand functions with constant marginal utility of income play a very relevant role in the inter-temporal context.
