we make use of the general monetary model here, where L is no longer assumed constant, and money demand is inversely related to the nominal interest rate. Recall from that earlier question inflation rate in Korea is = 10% and inflation rate in Japan is = 0%. In addition, assume that the bank deposits in Japan pay 2% interest rate (i¥ = 2%). Compute the interest rate paid on South Korean won deposits (iwon). Using the definition of the real interest rate, show that the real interest rate in South Korea (rwon) is equal to the real interest rate in Japan (r¥) Suppose the Bank of Korea decreases the money growth rate from 15% to 10% and the inflation rate falls proportionately (one for one) with this decrease. If the nominal interest rate in Japan remains unchanged, what happens to the interest rate paid on Korean won deposits? Using time series diagrams (impulse graphs), illustrate how this decrease in the money growth rate affects South Korea’s nominal money supply MK; nominal interest rate iwon; price level PK; real money supply, and Ewon/yen over time. Several countries that have experienced hyperinflation adopt dollarization as a way to control domestic inflation. For example, Ecuador has used the U.S. dollar as its domestic currency since 2000. What does dollarization imply about the exchange rate between Ecuador and the United States? Why might countries experiencing hyperinflation adopt dollarization? Why might they do this rather than just fixing their exchange rate?

Question

we make use of the general monetary model here, where L is no longer assumed constant, and money demand is inversely related to the nominal interest rate. Recall from that earlier question inflation rate in Korea is = 10% and inflation rate in Japan is = 0%. In addition, assume that the bank deposits in Japan pay 2% interest rate (i_¥ = 2%).

Compute the interest rate paid on South Korean won deposits (i_won).

Using the definition of the real interest rate, show that the real interest rate in South Korea (r_won) is equal to the real interest rate in Japan (r_¥)

Suppose the Bank of Korea decreases the money growth rate from 15% to 10% and the inflation rate falls proportionately (one for one) with this decrease. If the nominal interest rate in Japan remains unchanged, what happens to the interest rate paid on Korean won deposits?

Using time series diagrams (impulse graphs), illustrate how this decrease in the money growth rate affects South Korea’s nominal money supply M_K; nominal interest rate i_won; price level P_K; real money supply, and E_won/yen over time.

Several countries that have experienced hyperinflation adopt dollarization as a way to control domestic inflation. For example, Ecuador has used the U.S. dollar as its domestic currency since 2000. What does dollarization imply about the exchange rate between Ecuador and the United States? Why might countries experiencing hyperinflation adopt dollarization? Why might they do this rather than just fixing their exchange rate?
