This study seeks to explore the external factors that are acting as constraints on the Cuban economy and to identify the main opportunities that are open to it and the main threats that it faces in the current context of uncertainty. In order to accomplish this, a balance-of-payments-constrained growth model is used which, unlike any other model of this type that has been used before, incorporates the effect of the different flows of foreign exchange on the short- and long-run growth paths of the Caribbean economy.
