The following questions are based on fixed exchange rate and/or flexible exchange rate regime in an open macroeconomic model. The answers must be written in your words along with graphical illustration. Without explaining in your words, the graphical illustration alone will not be credible. Also make sure you use the relevant symbols and notation on each of the lines and axis on the graph(s) to clearly indicate the working mechanism of variables.

Suppose the domestic and foreign interest rates are both initially equal to 4%. Now suppose the foreign interest rate rises to 6%. Explain what effect this will have on the exchange rate. Also explain what must occur for the interest parity condition to be restored.
