- The National Economy (or macroeconomics) focuses on the overall performance of the economy. - An economy's size can be measured in different ways. The value of production, the number of people employed, or their total income can be measured. - GDP: + Measures the economy's total production of goods and services (from trail bikes to pedicures) + Tracks the same economy over time. + Compares different economies at the same time. - National income accounts organize huge quantities of data collected from a variety of sources across the United States. - National income accounts keep track of the value of final goods and services (these are sold the final, or end, users) - Intermediate goods and services are those purchased for additional processing and resale (the chicken purchased by KFC).
