问题如下：
Assume
that the DM country has what is considered a low-yield safe haven currency
while the EM country has a high-yield currency whose value is more exposed to
fluctuations in the global economic growth rate. An increase in safe haven
demand would most likely:
选项：
A.increase the risk premium demanded by international
investors to hold assets denominated in the EM currency
raise the return earned on carry trade strategies
exert upward pressure on the value of the EM currency
解释：
During
times of intense risk aversion, investors will crowd into the safe haven
currency. This tendency implies an increased risk premium demanded by investors
to hold the EM currency.
解析：在风险厌恶上升的时期，投资者会涌向避险货币。这一趋势意味着，投资者持有新兴市场货币所需的风险溢价上升。因此只有A正确。
B选项的意思是如果DM currency appreciate带来的FXcarry trade return增加是么？
应该是减少是么? DM（borrowing currency）升值，EM贬值( investing currency ) ？
