12 Two Ways of Measuring GDP Dollar flow of expenditures on final goods=Dollar flow of income (and indirect cost) of final goods=
13 + + + = GDP + = GDP Expenditure Approach Resource Cost-Income Approach Personal consumption expendituresAggregate income:Employee CompensationIncome of self-employedRentsProfitsInterest+Gross private domestic investment+Government consumptionand gross investment+Non-income cost items:Indirect business taxes and depreciation+Net exports of goods and services= GDPNet income of foreigners+= GDP
14 Two Key Price Indexes: (1) Consumer Price Index (2) GDP Deflator
15 The Consumer Price Index (CPI) The consumer price index (CPI) measures the prices of a fixed "basket" of consumer goods.It is weighted according to each component's share of an average consumer's expenditures.
16 Composition of CPI Food and beverage (16.4%) Housing (40.5%) Apparel (4.2%)Transportation (16.6%)Other (5.0%)Medical care (6.0%)Education and Communication (5.4%)Recreation (5.9%)
17 Creating a Price IndexA price index is calculated by dividing the current price of a basket of goods by the price of the basket in a base year then multiplying by 100.
