3.4-3.5 Flashcards
shows by how many times an increase in any autonomous expenditure increases income
The Multiplier
refers to an economic factor that when increased or changed causes increases or changes in many other related economic variables
The Multiplier
investment increases when firms anticipate
lower interest rate or higher profits
the size of the Multiplier depends on the
slope of the AE curve
in the multiplier expression 1/1-b,
b = and 1=
b= marginal propensity to consume 1= total disposable income
the steeper the slope of the AE curve the ______ the Multiplier
larger
the gentler the slope of the AE curve the _______ the Multiplier
lower
is a process spreading overtime
The Multiplier
the size of the Multiplier depends on the slope of the AE curve which s determined by
- marginal propensity to consume
- marginal tax rate
- and in an open economy, the marginal rate of imports
the higher the MPC the _____ the slope of the AE curve
steeper
the higher the marginal rate of imports (MPM) the ______ the slope of the AE curve
gentler
the higher the Marginal Tax Rate, the ______ the slope of the AE curve
gentler
the 4 other multipliers in addition to Autonomous Expenditure Multiplier
- government expenditure multiplier (GEM)
- Autonomous tax multiplier (ATM)
- Balanced Budget multiplier (BBM)
- Impact of the Marginal propensity to import (MPM)
is the same as the general autonomous expenditure multiplier
GEM
GEM is expressed as
GEM = 1/1-b= change in Y/ change in G
for a public policy an increase or decrease in government spending has a
multiplier effect on GDP
if G increases by $50 million with a Multiplier of 4, what does it cause GDP to do?
increase by $200 million
3 things that can cause the Multiplier effect to be reduced
- if P changes
- if we are in an open economy
- if the MTR is positive
2 kinds of taxes
induced and autonomous
rise and fall as income varies
induced taxes
act as automatic stabilizers of the economy
induced taxes
if income goes up then the MTR __________ and disposable income _______
- rises to higher level
- is reduced
if income goes down MTR ____ and disposable income _____
- falls to lower level
- rises
autonomous taxes do not vary with
real GDP
autonomous taxes are determined by
the Government
