Abstract

Balance of payments constrained growth models are notable for their longevity. This is especially true for the case of Thirlwall’s Law, which defines that a country’s sustainable growth rate is given by the ratio between the income elasticity of exports and that of imports. In light of this, the current paper explores the hypothesis that the income elasticities of this type of models are endogenous. The debate on the latter is resurgent in the literature.  The results provide evidence that the ratio is, indeed, exogenous, and that the level of the real exchange rate influences economic growth as it determines such ratio. In other words, the real exchange rate is important for improving non-price competitiveness without, however, making the ratio between elasticities endogenous.
