This paper studies the relationship between inflation, output, money and interest rates in the euro area, using data spanning 1980-2000. The P model is shown to have considerable empirical support. Thus, the "price gap" or, equivalently, the "real money gap" (the gap between current real...

The paper discusses several issues related to how monetary policy should be conducted in an era of price stability. Low inflation (with base drift in the price level) and price-level stability (without such base drift) are compared, and a suitable loss function (corresponding to flexible...

The paper examines the transmission mechanism of monetary policy in an open economy with and without a binding zero bound on nominal interest rates. In particular, a foolproof way of escaping from a liquidity trap is presented, consisting of a price-level target path, a devaluation of the...

The optimal escape from a liquidity trap involves generating private-sector expectations of a higher future price level and higher future inflation. This lowers the real interest rate and reduces the recession during the liquidity trap. The problem, emphasized by Krugman, is that central-bank...

An independent central bank can manage its balance sheet and its capital so as to commit itself to a depreciation of its currency and an exchange rate peg. This way, the central bank can implement the optimal escape from a liquidity trap, which involves a commitment to higher future inflation....
