Accepted Answer

Prices are flexible in the short run

Question 4

Which type of unemployment does the AE model primarily help to explain?

Accepted Answer

Cyclical unemployment

Question 5

Suppose the marginal propensity to consume (MPC) is 0.8. If disposable income increases by $500, by how much will consumption increase?

Accepted Answer

$$400 = 0.8 	imes 500$$

Question 6

Question 9

A country experiences a rapid increase in foreign real GDP. What is the most likely effect on its net exports?

Accepted Answer

Question 10

Which of the following equations correctly represents the marginal propensity to consume (MPC)?
