2. Factors that shift the consumption function 1. Changes in wealth – shift the consumption function. – Example: value of stocks, bonds, consumer durables. 2. Changes in consumer expectations – Shift the consumption function. – Example: Pessimistic expectations decrease autonomous consumption. 3. Taxes and Transfers – Tax increase or decrease in transfers: decrease disposable income and shift the consumption function down. 4.Prices – Affect the purchasing power of assets.

6. Recessionary/Inflationary Gap?

7. Which AE line will cause a recessionary gap? Which AE line will cause an inflationary gap?

8. = 7,000-6,000 =1,000 A recessionary gap occurs when actual GDP falls SHORT of full employment GDP To increase AE, we need an increase in C, I, G or NX To eliminate a recessionary gap, AE must rise.

9. To Eliminate a Recessionary/Deflationary Gap Increase Consumption by a sufficiently large price drop, a decrease in taxes or an increase in transfers. Increase Investment – tax incentives. – lower interest rates Increase Government Spending Increase Exports and reduce Imports: make dollar weaker (increasing supply of dollars)

10. = 7,000-8,000 =-1,000 An inflationary gap occurs when equilibrium GDP is higher than full employment GDP To decrease AE, we need a decrease in C, I, G or NX To eliminate an inflationary gap, AE must fall.

11. To Eliminate an Inflationary Gap Decrease Consumption by a sufficiently large price increase, an increase in taxes or a decrease in transfers. Decrease Government Spending Increase interest rates to decrease spending Decrease net exports and increase imports: stronger dollar.

12. 3.If the economy is at equilibrium, is total spending greater, less than or equal to Output? Do Inventories fall, rise or remain unchanged? Does the economy experience a recessionary gap or an inflationary gap? If an inflationary (recessionary) gap exists, how can the gap be closed?
