Topic 1: Review of AD/AS graph
What is the AD/AS graph used to illustrate??? 1. changes in price level
2. changes in quantity of real GDP/output
3. changes in employment
4. FISCAL POLICY action
![Page 3: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/3.jpg)
1. Draw an AD/AS graph at full employment equilibrium
![Page 4: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/4.jpg)
2. Draw an AD/AS graph showing a recession
![Page 5: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/5.jpg)
3. Draw an AD/AS graph showing inflation
![Page 6: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/6.jpg)
Reasons AD curve will shift:
• 1. Change in C (*wealth, income taxes, confidence)
*Wealth = the value of all things a person owns. ASSETS
How much $ a person earns (wage/income) is
NOT the same thing as wealth
![Page 7: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/7.jpg)
Reasons AD curve will shift:
• 2. Change in I (includes business taxes)• 3. Change in G • 4. Change in Xn
*FISCAL POLICY impacts this curve

Reasons SRAS curve will shift???
1. Change in resources quality and quantity
2. Change in price of resources (wages)3. Change in business taxes 4. Change in legalities 5. Change in technology6. Change in productivity
*This curve can SELF ADJUST in the long run due to flexible wages

Topic 4:Long Run Economic growth
Long Run Economic growth
1. The increase in real GDP which occurs over a period of time
2. The increase in real GDP per capita which occurs over a period of time
![Page 22: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/22.jpg)

Example: Real GDP this year is $11 million. Last year, real GDP was $10 million. What is the Growth rate???
![Page 23: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/23.jpg)
Ingredients of economic growth
Supply Factors: 1. Increases in the quantity and quality of
natural resources 2. Increases in the quantity and quality of
human resources/human capital (ex education)
3. Increases in the supply of capital stock 4. Improvements in technology
![Page 24: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/24.jpg)
Ingredients of Economic Growth
• 5. Demand Factor To achieve higher production created by
the supply factors, households, businesses and G must purchase the expanding output
![Page 25: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/25.jpg)
Ingredients of Economic growth
6. Efficiency productive efficiency: Use of resources in least costly way
allocative efficiency: produce what society
desires
![Page 26: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/26.jpg)
Graphing economic growth
• 1. Can be shown as an outward shift in a nation’s production possibilities curve
• 2. Can be shown as a rightward shift of a nation’s LRAS curve
![Page 27: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/27.jpg)

Economic growth and AD/AS graph
![Page 29: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/29.jpg)
Topic 5: The Financial System
• Consists of institutions that help match one person’s savings with another person’s investment
• The Financial System is made up of financial institutions (2 types) 1. financial markets 2. financial Intermediaries
![Page 30: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/30.jpg)
Financial Markets
• Institutions through which savers can directly provide funds to borrowers
• Examples: stock market and the bond market
![Page 31: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/31.jpg)
Financial Intermediaries
• Financial institutions through which savers can indirectly provide funds to borrowers
Example: Banks
![Page 32: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/32.jpg)
Topic 6: loanable funds theory of interest
• Looks at the impact of an action on REAL interest rates
![Page 33: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/33.jpg)
Nominal Interest Rate (i) The actual interest rate Measures the annual percentage increase in the
nominal (current dollar) valueNIR = RIR + inflation rate
Real Interest Rate (r)Interest rate taking inflation into account
RIR = NIR – inflation rate
![Page 34: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/34.jpg)
Nominal vs. Real Interest Rates
Example:You lend out $100 with 20% interest. Inflation is 15%.
Nominal interest rate = 20% Real interest rate = 5%
Example:You borrow $100 with 10% interest. Prices increase13%.
Nominal interest rate = 10% Real interest rate = -3%
![Page 35: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/35.jpg)
Topic 7: The Supply of Loanable Funds
The supply of loanable funds comes from SAVINGS – INVESTMENT for SAVINGS
![Page 36: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/36.jpg)
Examples of Savings:
• Purchase a certificate of deposit at a bank • Put money into savings account at a bank• Purchase corporate stock or bonds • Buy shares of a mutual fund
![Page 37: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/37.jpg)
Supply of Loanable funds
• A high real interest rate is an incentive tosave.
• The real interest rate is the OPPORTUNITY COST of spending
example: You decide to spend your money rather than save it – the interest rate you could have earned on your money is what
you give up
![Page 38: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/38.jpg)
![Page 39: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/39.jpg)
Reasons the Supply of loanable funds will shift:
1. A change in disposable incomemore disposable income = more savingsless disposable income = less savings
2. A change in taxes on interest income increase in taxes = less savings decrease in taxes = more savings
3. Anything that can impact savings (INVESTING FOR THE FUTURE)
4. FOREIGN INVESTMENT (SAVINGS)
![Page 40: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/40.jpg)
Supply in money market vs supply in loanable funds
• Money market graph = source of supply from the Fed
• Loanable Funds graph = source of supply from savers
![Page 41: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/41.jpg)
Topic 8: The demand for Loanable Funds
![Page 42: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/42.jpg)
• In order for firms to increase their capital stock, they must purchase machinery, tools and education for their workers.
• Firms must often borrow $ to do this
![Page 43: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/43.jpg)
Demand for Loanable funds
The sources of demand are the economy’s businesses who want to borrow $ to acquire more factories, inventory and equipment
The demand for loanable funds = BORROWING FOR INVESTMENT (BORROWING TO IMPROVE BUSINESS)
Investment = purchase of capital goods, construction and inventory IT IS NOT the buying of STOCK
![Page 44: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/44.jpg)
Examples of INVESTMENT
-GM spends $250 million to build a new factory-you buy $5,000 worth of computer equipment for your business - your parents spend $200,000 to have a new house built
![Page 45: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/45.jpg)
Demand for loanable funds
If firms must borrow funds, they regard theREAL rate of interest as a cost for anInvestment
Example: firms expect profits to increase by 5% due to a new investment of which they can borrow at a 3% rate of interest. Should this firm borrow the money???
![Page 46: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/46.jpg)
![Page 47: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/47.jpg)
Reasons the Demand for loanable funds will shift:
1. A change in investment tax credits (tax break) more tax credits = more investment less tax credits = less investment
2. A change in business/corporate tax lawsmore taxes = less investment less taxes = more investment
3. Change in the expected rate of profitmore expected profit = more investment less expected profit = less investment
4. A change in the government’s budget deficitincrease in budget deficit = increase in D decrease in budget deficit = decrease in D
![Page 48: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/48.jpg)
Topic 9: Relationship between supply and demand of Loanable funds
• The long run amount of savings directly affects the amount of money available for investment
• Savings rate in a country is the single most important determinant of investment
more investment = more capital stock more capital stock = Long run growth
![Page 49: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/49.jpg)
The market for Loanable Funds
• The market in which those who want to save supply funds and those who want to borrow to invest demand funds
Assume: only one financial market - all savers deposit their savings in this market
- all borrowers take out loans from this market
![Page 50: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/50.jpg)

At the equilibrium real interest rate, the amount borrowers want to borrow equals the amount lenders want to lend. SAVINGS = INVESTMENT

Practice:
• Tax incentives for savings increase. Draw a loanable funds graph to illustrate this.
![Page 52: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/52.jpg)
![Page 53: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/53.jpg)
Practice
• An investment tax credit increases the demand for loanable funds. Illustrate this on a loanable funds graph.
![Page 54: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/54.jpg)
![Page 55: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/55.jpg)
Practice
• The government borrows money to finance their budget deficit. Illustrate this action on a loanable funds graph.
![Page 56: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/56.jpg)
![Page 57: AP macroeconomics Unit 4: Long Run Economic growth and loanable funds](https://reader036.vdocuments.mx/reader036/viewer/2022062423/56814586550346895db26720/html5/thumbnails/57.jpg)
Crowding Out
• Crowding out = An increase in budget deficit increase real interest rates which decreases investment
• Remember: investment is important for long run economic growth – budget deficits reduce the economy’s growth rate and future standard of living
