Exchange-Rate-Based Stabilizations: An Analysis of Competing Theories

This paper uses a unified analytical framework to assess, both qualitatively and quantitatively, the relevance of the different hypotheses that have been proposed to explain the real effects of exchange rate-based stabilizations. The four major hypotheses analyzed are: (i) the supply-side effects associated with an inflation decline; (ii) the perception that the exchange rate peg is temporary; (iii) the fiscal adjustments that tend to accompany the peg; and (iv) the existence of nominal rigidities in wages or prices.
