Abstract

Background: One of the most important contributions of Structuralism is the contractionary devaluation hypothesis. It was developed for a world of fixed or semi-fixed exchange rates and low capital mobility. Although the literature has addressed new problems, such as the “balance sheet” effects, the literature has not considered the implications for the administration of an Inflation Targeting regime. Methods: We analyze the stability conditions of a stylized model that describes mainly the Latin-American economies, combining contractionary effects from devaluations with monetary policy rules. Results: When devaluations are contractionary exchange rate movements can be destabilizing. Stability is more likely if the Central Bank does not targets the output-gap. Foreign exchange reserve accumulation policies increase the likelihood of having a stable system. Conclusions: Contractionary effects from devaluations complicates the administration of monetary policy if Inflation Targeting is operative. Policies that aim to regulate capital flows, combined with foreign exchange reserve accumulation, can improve the Inflation Targeting regime.// Antecedentes. Una de las contribuciones más sobresalientes de la teoría estructuralista es la hipótesis de la devaluación contractiva. La misma fue desarrollada en un contexto de tipos de cambios fijos o semifijos y poca movilidad de capitales. Aunque la literatura ha incorporado nuevos problemas como los efectos “hoja de balance”, aún no se han examinado los problemas que la hipótesis plantea para la administración de un régimen de metas de inflación. Métodos: Analizamos las condiciones de estabilidad de un modelo estilizado, cuyas ecuaciones describen economías como las de América Latina, combinando los efectos contractivos de la devaluación con reglas de política monetaria. Resultados: En presencia de efectos contractivos de la devaluación existen efectos desestabilizadores asociados a los movimientos del tipo de cambio. La estabilidad es más probable si el Banco Central renuncia a estabilizar el producto. Las políticas de acumulación de reservas incrementan la probabilidad de obtener un sistema estable. Conclusiones: El carácter contractivo de la devaluación dificulta el manejo de la política monetaria bajo un esquema de metas de inflación. Las políticas que regulan los flujos de capitales, junto con la intervención cambiaria, pueden jugar un papel relevante en la administración exitosa de dicho régimen.
