It is assumed that everything else stays constant.
The economy has Consumption $90, Investment spending $100, Government expenditure on goods and services $80, Tax revenues $50, Exports $50, Imports $60. And marginal propensity to consume is assumed to be 0.7.
When the potential output of the economy (or long run output) is $250, what should be government spending in order to close an output gap?
If investment increases by $50 billion, by how much will aggregate demand change?
Aggregate demand will _______.
A.
increase by less than $50 billion because there will be fewer goods and services produced for consumption expenditure
B.
increase by more than $50 billion because the increase in aggregate income induces an increase in consumption expenditure
C.
probably decrease by $50 billion, but it depends on the change in aggregate supply
D.
increase by exactly $50 billion because investment is a component of aggregate demand
Answer the questions below based on the graph.
What is the value of autonomous expenditures?
What is the marginal propensity to consume?
What is the slope of the AE line?
