Abstract – This paper combines a Stock‐Flow Consistent open economy two‐country model with the Verdoorn‐Kaldor law, which posits a positive relationship between the rate of growth of output and productivity growth. The model shows the role of endogenous productivity as a shock magnifier and underlines the limits of the mechanisms of adjustment that rely exclusively on the “buffer” provided by flexible exchange rates. It also provides arguments in support of fiscal policy both in the context of flexible exchange rates and fixed exchange rates. Finally, it challenges the sustainability of austerity measures aimed to achieve external balance.
