Here Өt is the present year's rate of inflation, Өt-1 is the previous year's rate of inflation, ut is the actual rate of unemployment and un is the natural rate of unemployment. ἀ is the parameter that captures the effect of unemployment on the wage. The L.H.S (left hand side) of the equation is the change in the inflation rate. The above equation explains that the change in the rate of inflation depends upon the difference between the actual rate of unemployment and the natural rate of unemployment i.e., (ut-un). The rate of inflation would decrease when the actual rate of unemployment is higher than the natural rate of unemployment leading to Disinflation. The inflation rate would increase when natural unemployment rate is higher than the actual unemployment rate.
