2. GROSS DOMESTIC PRODUCT (GDP) The market value of all final goods and services produced in the economy in a given year. Take all final goods and services produced; Multiply them times their respective prices; Add up all the totals. The market value of all final goods and services produced in the economy in a given year. Take all final goods and services produced; Multiply them times their respective prices; Add up all the totals.

3. GDP Two interconnected sides: Output -- Firms produce output; for example, a computer manufacturer produces new computers. Income -- When firms produce output, they also generate income; wages; rents; interest; profit.

Income -- When firms produce output, they also generate income; wages; rents; interest; profit.

4. TOTAL MARKET VALUE  Take the quantity of goods produced and multiply them by their respective prices and add up the totals. -- Example: If an economy produced two cars at $15,000 a car and three computers at $3,000 a computer, the total value of these goods and services would be: ( 2 * $15,000 ) + ( 3 * $3,000 ) = $39,000  Take the quantity of goods produced and multiply them by their respective prices and add up the totals. -- Example: If an economy produced two cars at $15,000 a car and three computers at $3,000 a computer, the total value of these goods and services would be: ( 2 * $15,000 ) + ( 3 * $3,000 ) = $39,000

5. FINAL GOODS AND SERVICES Those goods and services that are sold to ultimate or final purchasers.

6. WHAT IS NOT INCLUDED IN GDP 1) Intermediate Products  Tires on a Car. A part of the final product. 2) Secondhand Sales  The sale of used goods. 3) The underground economy  Services performed in the home, such as, cleaning, cooking and providing free child care;  Transactions which occur that are not reported to official authorities -- these may be legal or illegal;  IRS estimates that about $100 billion in income escapes federal taxes each year;

13. NET EXPORTS  Purchases of foreign goods by consumers, firms and the government are subtracted when we calculate GDP because these goods were not produced in the U.S.  We must add to GDP any goods produced in the U.S. and sold abroad. Trade Deficit -- Occurs when we buy more goods from abroad than we sell; Trade Surplus -- Occurs when our exports exceed our imports;

15. REALITY PRINCIPLE What matters to people is the real value or purchasing power of money or income, not its face value. $$$
