supply function

supply function

a form of notation that links the DEPENDENT VARIABLE, quantity supplied (Qs ), with various INDEPENDENT VARIABLES that determine quantity supplied such as product PRICE (P), prices of factor inputs (Pl and P2 ), the state of technology (T), and business goals (G). The equation states that:

Changes in any of these independent variables will affect quantity supplied, and if we wish to investigate the particular effect of any one of these variables upon quantity supplied then we could (conceptually) hold the influence of the other independent variables constant (CETERIS PARIBUS), whilst we focus upon the particular effect of that independent variable.
