Such a combination of policies is called a policy mix, and this is a standard approach of macroeconomic policy. Therefore, the economic measures that the government recently has implemented can exert significant effects to maintain the expanding trend in the economy with the Bank's pursuit of powerful monetary easing.
That said, the cooperation between monetary and fiscal authorities entails difficulties in terms of ensuring public confidence toward macroeconomic policy. In economic theory, a policy mix is assumed to be conducted in an appropriate manner through monetary and fiscal policies based on their own particular policy objectives. In recent discussions, however, some seem to confuse a policy mix with debt monetization by central banks.
