What is an expenditures function?
An Expenditures Function is the mathematical relationship between income, autonomous expenditures, and induced expenditures.

AE = Aggregate Expenditures = (Autonomouns Expenditures + Induced Expenditures)
OE = Autonomous Expenditures
MPC = Marginal Propensity To Consume
Y = Income
