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....

The paper extends previous analysis of closed-economy inflation targeting to a small open economy with forward-looking aggregate supply and demand, and with stylized realistic lags in the different transmission channels for monetary policy. The paper compares targeting of CPI and domestic...

How do exchange rate bands work compared to completely fixed rates (between realignments); or, more precisely, what are the dynamics of exchange rates, interest rates, and central bank interventions within exchange rate bands? Does the difference between bands and completely fixed exchange rates...

Under the assumption of no arbitrage, the credibility of an exchange rate target zone is tested by whether domestic interest rates fall within "rate-of-return bands" between the maximum and minimum home currency rate of return on a foreign investment in the absence of a devaluation. Under the...

The paper presents estimates of devaluation expectations for six EMS currencies relative to the Deutsche mark, for the period March 1979-May 1990. The estimation method is simple and operational, and consistently generates sensible results. The estimates are constructed by the adjusting interest...
