disposable income(income after tax) = consumption(expenditure) + savings
what is consumer sovereignty
the consumer dictates what is produce whilst wants and preferences can be altered
what is apc
average propensity to consume
what is aps
the average propensity to save
does apc and aps add to 1?
yes
what factors may impact a person’s APC or APS
- cultural(different cultures have different spending patterns)
- personality(some people may be cautious, others not as much)
- expectation- future plans alter spending and saving
however, the two most important factors influencing consumer decision
- level of income(more y means more c and s)
- age(with age may come with additional income)
what does the average propensity to save refer to
the proportion of your income that you spend relative to the overall income
what is the formula for aps
S/Y
savings / disposable income
what is the formula for apc
C/Y
Consumption/disposable income

marginal refers to the new or changed circumstance
propensity refers to the likelihood or willingness for someone to do something
i.e marginal propensity to consume is
likelihood of consuming their extra dollar earned
and f

△C/△Y
△ = change in…
what is the formula for mps

does mpc and mps add to 1
yes
what is the life cycle theory of consumption
there are three distinct stages that influence consumption patterns
young people = lower income, high spending, low saving, high borrowing
working life = income rises, low spending, high saving
retirement = income decreases, high spending, low saving
what does the life cycle theory of consumption tell us
in general, individuals on higher incomes tend to have lower apc,
APC falls with rising age, but then increases again upon retirement
what is utility maximisation
economists tend to think of people as utility maximisers meaning in other words everyone is trying to get the most amount of utility possible at all time
what factors influence individual choice
1.income
