Students analyze the aggregate economic behavior of the United States economy by defining, calculating and explaining the significance of the unemployment rate, the number of new jobs created monthly, an inflation or deflation rate, and a rate of economic growth.
Inflation is the rate of increase in the avergae price level for giids and services in the economy.
Inflation reduces the purchasing power of money. The number of unemployed people is the number of adults without jobs that are seeking work. The labor force is the total number of employed and unemployed adults. The unemployment rate is calculated by dividing the number of unemployed people by the labor force and multiplying the result by 100. A low unemployment rate is seen as another sign of prosperity in traditional economic analysis, because it means that the economy is at near full production and most people have jobs.
