Suppose the US experiences permanent technological improvements such that its long run economic growth rate increases by 2%. Explain through a systematic sequence of impacts on relevant variables how this affects the dollar-euro exchange rate, assuming that this technological improvement is germane to only the US and that there are no policy changes in either country.
Answer.
Technological improvement improves the performance of the economy which attracts the foreign investors because of increase in interest rate. This will lead to increase the demand for home currency which is the dollar here. Now rise in demand for the dollar will increase the exchange rate of dollar-euro. Exchange rates of the dollar to euro and demand for dollar currency is negatively related. for e.g, if the exchange rate of the dollar to euro is 1/0.8 now then after an increase in demand for currency it will be like 0.9/0.8.
