Answer:
the level of real GDP that exists when the economy is experiencing only frictional and cyclical unemployment.
Explanation:
Potential GDP output is the highest level of real GDP that an economy can achieve over a sustained period of time and at a constant inflation rate. Potential output is reached when the natural rate of unemployment exists.
Natural rate of unemployment = frictional + structural unemployment
An economy can temporarily reach an output level higher than potential, but it will cause a surge in the inflation rate that will soon lower real GDP.
