tailieunhanh - Lecture Principles of economics - Chapter 8: Measuring a nation’s income

After completing this chapter, students will be able to: Consider why an economy’s total income equals its total expenditure, learn how gross domestic product (GDP) is defined and calculated, see the breakdown of GDP into its four major components, learn the distinction between real GDP and nominal GDP, consider whether GDP is a good measure of economic well-being. | 8 THE DATA OF MACROECONOMICS 23 Measuring a Nation’s Income Measuring a Nation’s Income Microeconomics Microeconomics is the study of how individual households and firms make decisions and how they interact with one another in markets. Macroeconomics Macroeconomics is the study of the economy as a whole. Its goal is to explain the economic changes that affect many households, firms, and markets at once. Measuring a Nation’s Income Macroeconomics answers questions like the following: Why is average income high in some countries and low in others? Why do prices rise rapidly in some time periods while they are more stable in others? Why do production and employment expand in some years and contract in others? THE ECONOMY’S INCOME AND EXPENDITURE When judging whether the economy is doing well or poorly, it is natural to look at the total income that everyone in the economy is earning. THE ECONOMY’S INCOME AND EXPENDITURE For an economy as a whole, income must equal expenditure because: . | 8 THE DATA OF MACROECONOMICS 23 Measuring a Nation’s Income Measuring a Nation’s Income Microeconomics Microeconomics is the study of how individual households and firms make decisions and how they interact with one another in markets.

THE ECONOMY’S INCOME AND EXPENDITURE For an economy as a whole, income must equal expenditure because: Every transaction has a buyer and a seller. Every dollar of spending by some buyer is a dollar of income for some seller. THE MEASUREMENT OF GROSS DOMESTIC PRODUCT Gross domestic product (GDP) is a measure of the income and expenditures of an economy. It is the total market value of all final goods and services produced within a country in a given period of time. THE MEASUREMENT OF GROSS DOMESTIC PRODUCT The equality of income and expenditure can be illustrated with the circular-flow diagram. Figure 1 The Circular-Flow Diagram Spending Goods and services bought Revenue Goods and services sold Labor, land, and capital Income = Flow of inputs and outputs = Flow of dollars Factors of production Wages, rent, and profit FIRMS Produce and sell goods and services Hire and use factors of production Buy and consume goods and services Own and sell factors of production HOUSEHOLDS Households sell Firms buy MARKETS FOR FACTORS OF PRODUCTION Firms sell Households buy MARKETS FOR GOODS AND SERVICES .
