Calculating GDP Final goods and value added current output market prices Gross Domestic Product and Gross National Product 1. Calculating GDP Final goods and value added current output market prices 2. GDP and GNP 2. GDP and GNP Real and Nominal GDP (see table 2-3) Real and Nominal GDP (see table 2-3)

3. Price Indexes 1. The GDP deflator ---is the ratio of nominal GDP in a given year to real GDP of that year 2. The Consumer Price Index (CPI)--- measures the cost of buying a fixed basket of goods and services representative of the purchases of urban consumers. 3. The Producer Price Index (PPI)----raw materials and semi-finished goods. Price Indexes 1. The GDP deflator ---is the ratio of nominal GDP in a given year to real GDP of that year 2.

4. From GDP to Personal Disposable Income 1. GDP - Capital consumption allowance 2. NDP - Indirect taxes 3. NI - corporate profits -social insurance contributions + government and business transfers to persons + interest and dividends 4. PI - personal tax and non-tax payments 5. PDI ≡ consumption + saving From GDP to Personal Disposable Income 1. GDP - Capital consumption allowance 2. NDP - Indirect taxes 3. NI - corporate profits -social insurance contributions + government and business transfers to persons + interest and dividends 4. PI - personal tax and non-tax payments 5. PDI ≡ consumption + saving

5. Outlays and Components of GDP( Fig2-1) 1. Demand components (from the view of expenditures) A. Consumption B. Investment C. Government D. Net exports Total Demand for GDP(or Y) = C+I+G+NX Outlays and Components of GDP( Fig2-1) 1. Demand components (from the view of expenditures) A. Consumption B. Investment C. Government D. Net exports Total Demand for GDP(or Y) = C+I+G+NX

6. 2. Payments to factors of production (from the view of income) A. Labor B. Capital C. Profit About 3/4 of factors payments are payments to labor. Most of the remainder goes to pay capital. In oil-extraction economies, natural resources are a dominant factor of production. PDI= GDP + net factor income from abroad - depreciation - retained earnings + transfers - taxes

10. Some Important Identities 1. A Simple Economy (no government and foreign trade ) Demand for: ( GDP) Y≡ C+I Income from : ( GDP) Y≡ C+S ∴ C+I ≡ Y≡ C+S and I ≡ Y - C≡ S that is I ≡ S Some Important Identities 1. A Simple Economy (no government and foreign trade ) Demand for: ( GDP) Y≡ C+I Income from : ( GDP) Y≡ C+S ∴ C+I ≡ Y≡ C+S and I ≡ Y - C≡ S that is I ≡ S

11. 2. Reintroducing the government and foreign trade Demand : Y = C + I + G + NX Income : Y = YD + TA - TR ∵ C + S ≡ YD ∴ C + S ≡ YD ≡ Y + TR - TA ∴ S - I ≡ (G + TR - TA) + NX 3. Saving, Investment, Government Budget, and Trade
