TLDR
Thus the Theory of Purchasing Power Parity tells us that movements in the rate of exchange between the currencies of two countries tend, subject to adjustment in respect of movements in the “equation of exchange,” to correspond pretty closely to movements in the internal price levels of the two countries each expressed in their own currency. It follows that the rate of exchange can be improved in favour of one of the countries by a financial policy directed towards a lowering of its internal price level relatively to the internal price level of the other country. On the other hand a financial policy which has the effect of raising the internal price level must result, sooner or later, in depressing the rate of exchange.via the TL;DR App
