Summary

50

GDP is the most widely used measure of a nation’s economic performance. GDP is the market value of all final goods produced in the U.S. during a period of time regardless of who owns the factors of production.

51

GNP is the market value of final goods and services produced by U.S. residents, no matter where they are located.

52

The circular flow model is a diagram representing the flow of products and resources between businesses and households in exchange for money payments.

53

Flows must be distinguished from stocks. Flows are measured in units per time period, for example, dollars per year. Stocks are quantities that exist at a given point in time measured in dollars.

55

The expenditure approach sums the four major spending components of GDP: consumption, investment, government, and net exports.

56

The income approach sums the major income components of GDP, consisting of compensation of employees, rents, profits net interest and nonincome expenses for depreciation and indirect business taxes.

57

Net domestic product (NDP) is GDP minus depreciation

58

National income (NI) is total income earned by households and is calculated as NDP minus indirect business taxes.

59

Personal income (PI) is the total income received by households and is calculated as NI minus corporate taxes and Social Security taxes plus transfer payments, net interest, and dividends.

60

Disposable personal income (DI) is personal income minus personal taxes. DI is the amount of income a household has available to consume or save.

61

Nominal GDP measures all final goods and services produced in a given time period of production.

62

Real GDP measures all final goods and services produced in a given time period, valued at the prices existing in a base year.

63

The GDP chain price index is a broad price index used to convert nominal GDP to real GDP.
