Economic Growth: Definition, Types, Causes & Examples
Economic growth is an increase in the potential level of real output an economy can produce in a specified period of time (typically one year). Short-run economic growth is when the economy uses spare capacity in order to increase the real output. Long-run economic growth is an increase in long-run aggregate supply.
