What is an MPC?
The percentage of an overall salary increase that a customer spends on purchasing goods and services rather than saving is known as the marginal propensity to consume (MPC) in economics. The Keynesian macroeconomic theory includes a concept known as the marginal propensity to consume, which is determined as the change in consumption divided by the change in income.
A consumption line, which is a sloped line made by charting the change in income on the horizontal "x" axis and the change in consumption on the vertical "y" axis, is used to represent MPC.
- The percentage of additional income that is spent on consumption is known as the marginal propensity to consume.
- Depending on income, MPC fluctuates.
- MPC tends to be lower at higher income levels.
- The Keynesian multiplier, which describes the impact of additional investment or government spending as an economic stimulus, is mostly determined by MPC.
MPC=0.8
Multiplier=1/(1-MPC)=1/(1-0.8)=5
$300 billion more in government purchases
The initial change in consumption is equal to $300 billion times 0.8, or $240 billion.
$240 billion*0.8 to equal $192 billion for the second shift in consumption.
Demand fluctuation as a whole = $300 billion*5 = $1500 billion
$500 billion
the AD curve moves $1.5 trillion to the right.
