老师，这题让indicate，是不是要先说明二选一哪一个国家会看到货币升值？然后解释原因？我这么答能不能得分: country X is more likely to experience an appreciate in local currency. Because: 1) Recall the covered interest rate parity, real interest rate should be the same across countries, as country X has a lower inflation rate, it is more likely to have an appreciation in local currency. 2) As new law's that allows foreign direct investment has been passed in country X, international capital is more easily inflowing to country X which could exert local currency appriciation. 3) The current account surplus of country X pushes it's local currency to appreciate. 4) Although country Y has a higher expected GDP growth and government bond rate, which seems more attractive for international capital to inflow to lead local currency appreciation, the deny of direct foreign investment law offset this advantage. Thus country x is more likely to have a currency appriciation.
