DP11966 A Central Bank Theory of Price Level Determination
The remittances’ policy and the balance sheet of the central bank are important elements to specify for the control of the price level. A central bank appropriately capitalized can succeed to control prices by setting the interest rate on reserves, holding risk-free assets and rebating its income to the treasury - from which it has to maintain financial independence. If the central bank undertakes unconventional open-market operations, either it has to give up its financial independence or leaves the economy exposed to self-fulfilling inflationary spirals or chronic liquidity traps.
