• Assumptions:– Full Employment– Fixed Resources and Technology
• Movements– Along curve shows opportunity cost– Outward shift illustrates economic growth– Inward shift indicates destruction of resources
• Producing Capital Goods will lead to greater economic growth than producing consumer goods. (Butter will lead to more growth than guns)

2 Supply and Demand
![Page 7: 1.Production Possibilities Frontier 2.Supply and Demand 3.Currency Market 4.AD-AS Model 5.Loanable Funds Model 6.Phillips Curve 7.Money Market.](https://reader038.fdocuments.us/reader038/viewer/2022110400/56649da05503460f94a8b4f4/html5/thumbnails/7.jpg)
• Demand Changes when:– Income changes– Related Products, complements and substitutes,
(price or quality change)– Expectations (future price change)– Consumers (more or less added)– Tastes, Fads, Preferences change
![Page 8: 1.Production Possibilities Frontier 2.Supply and Demand 3.Currency Market 4.AD-AS Model 5.Loanable Funds Model 6.Phillips Curve 7.Money Market.](https://reader038.fdocuments.us/reader038/viewer/2022110400/56649da05503460f94a8b4f4/html5/thumbnails/8.jpg)

• Supply Changes When:– Input prices change (resources and wages)– Government (tariffs, quotas, and subsidies)– Number of sellers change– Expectations (about price and product profitability
change)– Disasters (weather, strikes, etc..)

3 Currency Market
![Page 16: 1.Production Possibilities Frontier 2.Supply and Demand 3.Currency Market 4.AD-AS Model 5.Loanable Funds Model 6.Phillips Curve 7.Money Market.](https://reader038.fdocuments.us/reader038/viewer/2022110400/56649da05503460f94a8b4f4/html5/thumbnails/16.jpg)
Currency Terms• Appreciation: Currency is increasing in
demand (stronger dollar)– U.S. Currency will appreciate when more
foreigners: travel to the U.S., buy more U.S. goods or services, or buy the U.S. dollar to invest in bonds
![Page 17: 1.Production Possibilities Frontier 2.Supply and Demand 3.Currency Market 4.AD-AS Model 5.Loanable Funds Model 6.Phillips Curve 7.Money Market.](https://reader038.fdocuments.us/reader038/viewer/2022110400/56649da05503460f94a8b4f4/html5/thumbnails/17.jpg)
Currency Terms• Depreciation: Currency is decreasing in
demand (weaker dollar) Being SUPPLIED in exchange for other currency.– U.S. Currency will depreciate when fewer
foreigners: travel to the U.S., buy fewer U.S. goods or services, or sell the U.S. dollar to invest in their own bonds

Aggregate Demand
AD (C + I + G + X)

Real GDP
Downward sloping:1. Real-Balances Effect: change in purchasing power
2. Interest-Rate Effect: Higherinterest rates curtail spending
3. Foreign Purchase Effect: Substitute foreign products for U.S. products
![Page 24: 1.Production Possibilities Frontier 2.Supply and Demand 3.Currency Market 4.AD-AS Model 5.Loanable Funds Model 6.Phillips Curve 7.Money Market.](https://reader038.fdocuments.us/reader038/viewer/2022110400/56649da05503460f94a8b4f4/html5/thumbnails/24.jpg)
Aggregate Demand
• Determinants of AD:– C + I + G + Nx– An increase in any of these will increase AD and shift
the curve to the right.
– A decrease in any of these will cause a decrease in AD and shift the curve to the left
![Page 25: 1.Production Possibilities Frontier 2.Supply and Demand 3.Currency Market 4.AD-AS Model 5.Loanable Funds Model 6.Phillips Curve 7.Money Market.](https://reader038.fdocuments.us/reader038/viewer/2022110400/56649da05503460f94a8b4f4/html5/thumbnails/25.jpg)
Aggregate Demand Determinants
• Consumption– Wealth– Expectations– Debt– Taxes
• Investment– Interest Rates– Expected Returns
• Technology• Inventories• Taxes
• Government– Change in Gov. spending
• Net Exports– National Income Abroad– Exchange Rates
![Page 26: 1.Production Possibilities Frontier 2.Supply and Demand 3.Currency Market 4.AD-AS Model 5.Loanable Funds Model 6.Phillips Curve 7.Money Market.](https://reader038.fdocuments.us/reader038/viewer/2022110400/56649da05503460f94a8b4f4/html5/thumbnails/26.jpg)
Aggregate Supply Factors:
• R: resource prices (wages and materials, as well as OIL)
• A: actions by government (Taxes, Subsidies, more regulation)
• P: productivity (better technology)
![Page 27: 1.Production Possibilities Frontier 2.Supply and Demand 3.Currency Market 4.AD-AS Model 5.Loanable Funds Model 6.Phillips Curve 7.Money Market.](https://reader038.fdocuments.us/reader038/viewer/2022110400/56649da05503460f94a8b4f4/html5/thumbnails/27.jpg)
Aggregate Supply
• Short Run:– Assumes that nominal wages
are “sticky” and do not respond to price level changes.
– Is Upward sloping as businesses will increase output to maximize profits
• Long Run:– Curve is vertical because the
economy is at its full-employment output.
– As prices go up, wages have adjusted so there is no incentive to increase production.

Demand for Loanable Funds Curve
The demand for loanable funds shows the relationship between the real interest rate and the quantity of loanable funds demanded. It shows that the quantity of loanable funds will be lower at a high real interest rate than at a lower real interest rate.

Equilibrium in the Loanable Funds Market
![Page 39: 1.Production Possibilities Frontier 2.Supply and Demand 3.Currency Market 4.AD-AS Model 5.Loanable Funds Model 6.Phillips Curve 7.Money Market.](https://reader038.fdocuments.us/reader038/viewer/2022110400/56649da05503460f94a8b4f4/html5/thumbnails/39.jpg)
Shifts in Demand for Loanable Funds
The major determinant of the demand for loanable funds is expected profit. When the expected profit changes, the demand for loanable funds changes. The greater the expected profit of new capital, the greater is the amount of investment and the greater is the demand for loanable funds. When the expected profit increases and we earn more from our investment, the more affordable it becomes to borrow loanable funds – even when the interest rate.

Shifts in Supply of Loanable Funds
1. Disposable income (shifts the supply of loanable funds)
2. Wealth (shifts the supply of loanable funds)
3. Expected future income (shifts the supply of loanable funds)
4. Default risk (shifts the supply of loanable funds)
