Shifts in AD Flashcards
Define disposable income
income left over after paying taxes
Define the multiplier effect
where an initial increase in injections leads to a larger increase in AD
What does the multiplier ratio tell us?
how much GDP will increase in total following an initial injection into the economy
What are the three ways to calculate the multiplier ratio?
1/MPW
1/(1-MPC)
1/ MPT + MPS + MPM
What three areas do interest rates affect?
consumers who are saving
consumers who are borrowing
firms borrowing to invest
high IR = more saving, less borrowing
How do lower pension savings impact AD?
pensioners have to save more for future
increased saving, decrease consumption
Ricardo Sousa theory
50% of people own homes
- thus 50% feel richer and spend more, 50% feel poorer and save more
Europe wealth effect = 0%
Savings ratio calculation
total savings / disposable income x 100
(as a percentage)
Define savings ratio
the percentage of disposable income that consumers will save
