A, inflation in the united states exceeds the inflation in taiwan.
00:06
So to know whether the net exports of us will increase or not, we need to understand what happens to the real exchange rate between us and taiwan's currency.
00:17
The real exchange rate is the nominal exchange rate times the price level in the us divided by the price level in taiwan.
00:48
So when the inflation is higher in the us compared to taiwan, the real exchange rate will increase because the price level in the us increases.
01:25
And when the real exchange rate increases, it means for every unit of us export that the people will have to pay more or taiwan produce goods.
01:34
And as a result, us exports will decrease.
01:38
And also when the real exchange rate increases, the imports for us citizens from taiwan becomes cheaper, so imports will increase.
01:47
So the net exports of the us will decrease in this case.
02:03
Part b, the yen to dollar exchange rate decreases from 120 yen to dollar to 95 yen to dollar.
02:11
So the nominal exchange rate decreases from 121 yen to dollar to 95 yen to dollar.
02:18
It means the us dollar becomes cheaper for japanese people.
02:36
And as a result, the cost of us exports in japan falls since now they'll have to pay less amount in terms of yen.
02:55
So this will increase the demand for us exports in japan.
03:10
And also when the exchange rate falls, it means that now the us will have to pay more for the same amount of yen imports.
03:17
And as a result, imports will decrease.
03:20
The net effect will be that the net exports of the us will increase.
03:37
Part c, the growth rate of chinese gdp exceeds the growth rate of us gdp...
