Economists say that there are no tradrle-off in unemployment and inflation in the long run. The long run Philips curve explained this relationship. In the natural rate theory the decrease in unemployment would result to increase in inflation. Inflation does not get long enough since the government would have some economic policies, and salary increases to implement so it could help the people. It would result to Philips curve short run. If the natural rate of unemployment and the number of unemployment are the same, it would result to aggravated production which could switch to a long run.
