But the NAIRU theory says that this is not the whole story, so that the trade-off breaks down: a persistently higher inflation rate is eventually incorporated as higher inflationary expectations.
As mentioned above, Abba Lerner had developed a version of the NAIRU before the modern "natural" rate or NAIRU theories were developed.
Again start with the unemployment rate equal to the NAIRU.
Finally, the NAIRU theory says that the inflation rate does not rise or fall when the unemployment equals the "natural" rate.
In macroeconomics, the case where the actual unemployment rate equals the NAIRU is seen as the long-run equilibrium because there are no forces inside the normal workings of the economy that cause the inflation rate to rise or fall.
One of the major problems with the NAIRU theory is that no one knows exactly what the NAIRU is (while it clearly changes over time).
