1. Starter  Do you think the state of the economy has any affects on the student loans you can receive for college or the jobs you may have?  Why? Or Why not?  How do we know if the economy is doing well or not?

2.  GDP CHAPTER 12.1

3. Why does measuring the Economy matter?  National income accounting uses statistical measures of income, spending, and output to help people understand what is happening to a country's economy.  The economic decisions of millions of individuals determine the fate of the nation's economy.  Understanding what is happening to the country's economy will help you make better personal economic decisions.  Macroeconomists use national income accounting:  statistical measures that track nation's income, spending, output  gross domestic product (GDP) is most important measure

4. Gross Domestic Product (GDP)  GDP--market value of final goods, services produced in set time period  To be included in GDP, product must fulfill three requirements:  must be final, not intermediate product (Ex: included- cheeseburger, excluded- cow parts)  must be produced during the time period, regardless of when sold (Ex: included-new car, excluded- used car)  Time period is usually a year, or quarter (3 months)  must be produced within nation's borders

5. Calculating GDP  Expenditures approach often used to measure GDP; tracks four sectors  GDP=C+I+G+X  Consumption--household spending on durable, nondurable goods, services  Investment--business spending on capital goods (construction or equipment), inventory (unsold goods kept on hand)  Government spending--federal, state, local; not transfer payments (defense, highways, education)  Net exports--value of exports minus value of imports

6. Types of GDP  When GDP grows, economy creates more jobs and business opportunities  Nominal GDP--price levels for the year in which GDP is measured - states GDP in terms of current value of goods and services  Real GDP--GDP adjusted for changes in prices  estimate of GDP if prices were to remain constant from year to year

7. What GDP Does Not Measure  GDP does not measure all output, such as  nonmarket activities--free services with potential economic value (Ex: performing own home repairs, volunteer work)  underground economy--unreported market activities  Illegal activities are unreported  when goods are rationed or restricted, black market arises  Legal activities paid for in cash not always declared  Estimates suggest underground economy 8 to 10 percent of U.S. GDP  GDP also does not measure quality of life  Countries with high GDPs have high living standards  GDP does not show how goods and services are distributed  GDP does not show what goods are being made or services offered

8. Other Economic Performance Measures  Other measures of economic performance derived by adjusting GDP  Gross national product (GNP)--market value of all final goods, services  GDP plus products produced abroad; minus domestic products of foreign nations  Net national product (NNP)--GNP minus depreciation of capital stock  National income (NI)--total income from production of goods, services  Personal income (PI)--income received by people from all sources  Disposable personal income (DPI)--personal income minus income taxes  actual income available for consumer spending
