The Data of Macroeconomics

Questions for Review 1. GDP measures the total income earned from the production of the new final goods and services in the economy, and it measures the total expenditures on the new final goods and services produced in the economy. GDP can measure two things at once because the total expenditures on the new final goods and services by the buyers must be equal to the income earned by the sellers of the new final goods and services. As the circular flow diagram in the text illustrates, these are alternative, equivalent ways of measuring the flow of dollars in the economy. 2. The consumer price index measures the overall level of prices in the economy. It tells us the price of a fixed basket of goods relative to the price of the same basket in the base year. 3. The Bureau of Labor Statistics classifies each person into one of the following three categories: employed, unemployed, or not in the labor force.

These include the following: Gross Domestic Product—the market value of all final goods and services produced in a year. The Unemployment Rate—the percentage of the civilian labor force who do not have a job. Corporate Profits—the income of corporations after payments to workers and creditors. It gives an indication of the general financial health of the corporate sector. The Consumer Price Index (CPI)—a measure of the average price that consumers pay for the goods they buy; changes in the CPI are a measure of inflation. The Trade Balance—the difference between the value of goods exported abroad and the value of goods imported from abroad. In looking at the economic statistics, most people want to see a low and stable inflation rate of about 2–3 percent, a low and stable unemployment rate of about 5 percent, and GDP growth in the 3–4-percent range. This indicates the economy is“healthy” and per5
