Firms innovate and streamline. Efficiency, productivity and competitiveness are the buzzwords of this phase. The same wages generate more products. This is technological deflation. It is beneficial to the economy in that it frees economic resources and encourages their efficient allocation.
Real incomes rise and generate increased demand and production.
Inevitably, technical deflation leads to a restraint in the general price level. Inflation is kept to sustainable levels. This phase is known as 'disinflation'. It is a transitory phase. The transition from hyperinflation or high inflation to a supportable level of inflation is a matter of one or two decades.
