From the perspective of what has happened since, there are three things worth noting about this analysis. First, the root cause of the crisis is poor government policy. In these models, the source of the upward trend in the shadow exchange rate is the government’s need for seignorage; solve the fiscal problem and there would be no crisis. And the speculative target is provided by the government’s pursuit of inconsistent policies: persistent deficits together with an exchange rate peg. So the models basically imply that governments get the crisis they deserve.

At very favorable exchange rates, few firms would be balance-sheet constrained; so at low eP*/P the direct effect of the exchange rate on aggregate demand would be minor. At very unfavorable real exchange rates, firms with foreign-currency debt would be unable to invest at all, and therefore the direct exchange-rate effect on demand would be trivial at the margin. But in an intermediate range, the effect might be large enough to outweigh the direct effect on export competitiveness, so that over that range depreciation of the currency would be contractionary rather than expansionary.
