the potential level of output.<br />
There is full employment in<br />
the economy - the natural rate<br />
of unemployment occurs at<br />

2. Equilibrium output does not<br />
reach the level of potential<br />
output. All the possible<br />
(accessible) inputs (factors of<br />
production) are not effectively<br />
used. The rate of unemployment<br />
is higher then the natural rate of<br />
unemployment. There is<br />
involuntary unemployment in<br />
the economy. Output gap =<br />
potential output – actual output.<br />

3. Equilibrium output reaches the<br />
higher level then the potential<br />
level. The actual rate of<br />
unemployment is temporarily<br />
lower than the natural rate of<br />
unemployment. The economy is<br />
“overheated”. This situation is<br />
always temporary. It is impossible<br />
for the economy to be kept under<br />
such conditions in a long term.<br />
