1. Aggregate Expenditures Model (Keynesian Economic Model -or- Keynesian Cross) Explain how the economy’s equilibrium RGDP relates to total spending and how changes in total spending affect levels of RGDP Clarify the basic determinants of the levels of output and employment. Assumes a constant price level (is a “SHORT RUN” model / view of the economy)

2. Aggregate Expenditures Real GDP Real National Income AE Full Output Potential GDP *Assumes constant Price level*

3. I. History A. Classical Economists Market systems would ensure full employment of the economy’s resources Acknowledge deviations from full employment but insist there are “automatic adjustments” {prices, wages, interest rates} to restore the economy “self - correcting”

4. Ex- if you experience a decrease in output and employment….. Lead to lower prices, wages and interest rates….. Lower prices = increase C Lower interest rates = increase Investment Lower wages = increase employment

5. Say’s Law If You Build It; They Will Come Ensure full employment Self correcting The very act of producing goods generates an amount of income = to the value of the goods produced. “Supply Creates Its Own Demand” There will always be sufficient consumption Works as a “LONG RUN” view

6. Specifically, what aspects of Say’s Law did Keynes criticize and for each point he criticized, what was his offered solution? A. Not all income will be spent Unsold goods = accumulated inventory Producers reduce output and cut employment….= recession or depression

7. B. Capitalism is not self regulating Failure of certain fundamental economic decisions (saving and investment) to be synchronized In Short Run – prices and wages are inflexible Extended periods of overproduction and underconsumption …… = ? Recession or depression will prevail before prices or wages significantly change.

8. Keynes’ Solution ***need govt. deficit spending ……………GREAT DEPRESSION and NEW DEAL created believers of KEYNESIAN ECONOMICS

9. ………….Led to……………. 1946 Full Employment Act – responsibility of the govt. to promote maximum employment, ….. production, and purchasing power, and price stability (control inflation) ….now much of it shared with Fed Reserve
