Credibility And The Dynamics Of Stabilization Policy

Credibility and the Dynamics of Stabilization Policy

This paper studies price stabilization policy under both predetermined and flexible exchange rates. Under predetermined exchange rates, a non-credible stabilization program results in an initial expansion of output, followed by a later recession. The initial expansion accompanies an appreciating real exchange rate. Under flexible exchange rates, the recession occurs at the beginning of the program. The real exchange rate appreciates sharply on impact but depreciates afterwards. Lack of credibility is more costly under predetermined exchange rates because the real effects are more pronounced.

Credibility and the Dynamics of Stabilization Policy

Exchange-Rate-Based Stabilization under Imperfect Credibility

This paper analyzes stabilization policy under predetermined exchange rates in a cash-in-advance, staggered-prices model. Under full credibility, a reduction in the rate of devaluation results in an immediate and permanent reduction in the inflation rate, with no effect on output or consumption. In contrast, a non-credible stabilization results in an initial expansion of output, followed by a later recession. The inflation rate of home goods remains above the rate of devaluation throughout the program, thus resulting in a sustained real exchange rate appreciation.
