Question

does ppp eliminate concerns about long-term exchange rate risk?

i need 3 arguments that disagree with this question.

Answer 1

yes. studies have shown that exchange rate movements are related to inflation differentials in the long run. based on PPP,the currency of a high inflation country will depreciate against the dollar.A subsidiary in that country should generate inflated revenue from the inflation ,which will help offset the adverse exchange effects when its earnings are remitted to the parent . If a firm is focussed on long term performance,the deviations from PPP will offset over time . In some years,the exchange rate effects may exceed inflation effects,and in other years the inflation effects will exceed the exchange rate effects.

counter points

No. Even if the relationship between inflation and exchange rate effects is consistent,this does not guarantee that the effects on the firm will be offsetting. A subsidiary in a high inflation country will not necessary be able to adjust price level to keep up with the increased costs of doing business there.The effects vary with each MNC's situation.Even if the subsidiary can raise its prices to match the rising costs,there are short term deviations from PPP. The investors who invest in an MNC's stock may be concerned about short term deviations from PPP,because they will not necessarily hold the stock for the long term.Thus,investors may prefer that firms manage in a manner that reduces the volatility in their performance in short run and long run periods.
