Average Propensity
Average propensity to consume/save is the total proportion of income that is consumed or saved
pretty sure this old definition is wrong
Includes the autonomous expenditure in propensity to consume, this means that it falls as income rises since the autononomous component does not increase with the income.
Ceteris Paribus, assuming constant, non-changing MPC and MPS: As Income rises, average propensity to consume falls. As Income rises, average propensity to save increases.
Warning
double check if
below is normal C or different C w/ autonomosus expenditre
