Credible commitment to optimal escape from a liquidity trap

Description:

"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. This commitment mechanism works even though, realistically, the central bank cannot commit itself to a particular future money supply. It supports the feasibility of Svensson's Foolproof Way to escape from a liquidity trap"--National Bureau of Economic Research web site.
