This paper studies, both theoretically and empirically, tradable (T) and non-tradable (N) sectorial profit rates dynamics in a small, price-taker peripheral economy with foreign exchange controls and parallel exchange rate (ER) markets. Using a state-space econometric representation of the Argentine economy for the period 2016-2023, we found evidence to support three main hypotheses derived from the theoretical models. First, an official exchange rate depreciation increases tradable goods profit rates, but has no effect on non-tradeable goods profitability. Second, the rise of the financial exchange rate increases sector N’s profit rate but has no effect on T’s. Moreover, this effect depends on the magnitude of the ER gap in a positive, but in a non-linear way. Third and finally, over sufficient time, both profit rates tend to influence each other, through the action of competition. This means that, eventually, and increase (depreciation) in the official exchange rate exerts its influence in sector N’s profit rate; while, if sufficiently persistent and big enough, a rise in the financial ER ends up affecting sector T’s profit rate too.
