Consider the data presented in the table:

Actual aggregate expenditure or output (Y) (billions of $)	Consumption (C) (billions of $)	Planned investment (billions of $)	Government spending (G) (billions of $)	Net exports (NX) (billions of $)	Unplanned investment (inventory change) (billions of $)
500	300	150	100	50
600	350
700	400
800	450
900	500

Based on the assumptions of the aggregate expenditure model, fill in the columns for planned investment, government spending, and net exports.

Instructions:Enter the values into the table above.

a. For each level of actual aggregate expenditure, calculate unplanned inventory investment.

Instructions:Enter the values into the table above. If the value is negative, then be sure to enter a minus sign.

b. What is the equilibrium level of aggregate expenditure in this economy?

Instructions:Enter a number rounded to the nearest whole number. Answer in the billions of dollars.

c. Suppose that planned investment increases by $50 billion.What is the new equilibrium level of aggregate expenditure in this economy?

Instructions:Enter a number rounded to the nearest whole number.Answer in the billions of dollars.

d. What is the marginal propensity to consume in this economy?

Instructions:Enter a number rounded to two decimal places as necessary.

e. What is the expenditure multiplier in this economy?

Instructions:Enter a number rounded to two decimal places as necessary.
