The aim of this paper is to present some considerations about the relationship among exchange rates, external constraints and economic growth in a formal model that considers two regions, one of developed and the other of developing countries, which interact via international trade. It is assumed that the external constraint acts on the developing economy, which is affected by variations in level of the real exchange rate to the extent that changes in these policies affect the functional distribution of income and, therefore, the decisions of the planned spending on business innovation. The findings show that variations in the real exchange rate alter the external constraint in this region and allow it to reach a higher rate of long-term output growth.
