According to Keynesian theory, inflation and economic stagnation cannot happen simultaneously. Using monetary policy to control one factor, say inflation, can lead to further economic woes.
Countries around the world have tried different methods to tackle stagflation. Based on such experiences, it is seen that there is usually a time lag before an economy turns around. The intervening period is marked with increased business bankruptcies and hardship to the public at large.
Policymakers use a combination of fiscal and monetary policies to control stagflation. While increased spending by the government or reduced taxes stimulate growth, monetary policies are used to manage liquidity in the system and to control inflation. Governments also aim to stabilize key institutions so as to retain public confidence in their operations.
Measures to reduce costs, such as more efficient design of processes and machinery as well as alternative technologies and conservation of resources can also contribute favorably to reverse stagflation.
