Chapter 7: GDP: Measuring Total Production and Income Gross Domestic Product Measures Total Production An Equation for GDP and Some Actual Values Consumer spending on services is greater than the sum of spending on durable and nondurable goods. Business fixed investment is the largest component of investment. Purchases made by state and local governments are greater than purchases made by the federal government. Imports are greater than exports, so net exports are negative. 7.1 LEARNING OBJECTIVE Explain how total production is measured.

Chapter 7: GDP: Measuring Total Production and Income 20 of 41 © 2015 Pearson Education, Inc. Comparing Real GDP and Nominal GDP The current base year for calculating prices is 2009, so real and nominal GDP are equal in 2009. Growth figures reported in the media are the growth in real GDP. Since prices have generally increased since 2009, real GDP is less than nominal GDP, and the opposite is true before 2009. Nominal GDP and real GDP: 1990-2012

Chapter 7: GDP: Measuring Total Production and Income Other Measures of Total Production and Total Income Gross National Product (GNP) Disposable Personal Income (Y D ) National Income Personal Income Become familiar with other measures of total production and total income. 7.4 LEARNING OBJECTIVE Gross national product (GNP) is the value of final goods and services produced by residents of the United States, even if the production takes place outside the United States. National income is calculated as GDP minus the consumption of fixed capital, or depreciation. Disposable personal income is equal to personal income minus personal tax payments (Y – T). Personal income is income received by households.
