In general, there is consensus that monetary policy, through low and stable prices, can assist in creating a conducive environment for sustainable economic growth and development. I would, however, like to note that stable prices do not mean that prices of good and services will not change at all.
Relative prices in a market economy will always change in response to changes in relative scarcities. For example, during or after a drought food prices are likely to increase. While monetary policy can succeed in maintaining stable prices, it is less successful in controlling real variables, such as the real interest rate or the unemployment rate.
