Full-employment level of output, YFE long-run level of output
It is the level of output consistent with “full employment1.
When the economy is operating at its normal pace (not too
fast and not too slow), then we can say that the economy is
at its full employment.
The unemployment rate at YFE is called the non-accelerating
inflation rate of unemployment (NAIRU) or natural rate of
unemployment (NRU).
1 You can interpret the termfull employment as
Good/productive” workers find iteasy” to find a job.
Young/inexperienced” workers find iteasy” to find their first job.
Old” workers are not forced out of the labour force if they lose their jobs (i.e., no
discouraged workers).

Full employment DOES NOT mean that everyone is
working because
Frictional unemployment unemployment that results
from the turnover in the labour market as workers move
between jobs.
Structural unemployment long-term and chronic
unemployment arising from imbalances between the
skills and other characteristics of workers in the market
and the needs of employers.
The labour market is dynamic (people constantly move
in and out of the labour market).
There are frictions in the economy (some
industries/regions expand while some industries/regions
contract)
