The document discusses several key economic concepts:
- Economic growth refers to the increase in a country's production of goods and services over time. It can be measured in real or nominal terms.
- Full employment means all available labor resources are being used efficiently. Unemployment that remains is considered frictional.
- Price stability is when prices do not change much over time and the economy does not experience inflation or deflation.
- The business cycle shows the typical phases of expansion, peak, contraction and trough that economies experience over time due to fluctuations in aggregate demand and supply.
