Arrange the following concepts in the correct order to explain the relationship illustrated by the Long Run Phillips Curve: A) Economy reaches natural rate of unemployment, B) Inflation expectations stabilize, C) Short-run Phillips Curve shifts, D) No trade-off between inflation and unemployment exists.

The Long Run Phillips Curve shows that there is no lasting trade-off between inflation and unemployment. First, the economy eventually reaches what is called the natural rate of unemployment, which is the level of unemployment that exists when the economy is healthy. Once this happens, people's expectations about inflation stabilize because they realize that high inflation does not lead to lower unemployment in the long run. As these expectations become stable, the short-run Phillips Curve shifts, reflecting that policymakers cannot consistently lower unemployment by accepting higher inflation. Ultimately, this leads to the understanding that in the long run, there is no trade-off between inflation and unemployment; they are influenced by different factors.
