(9) (24 points) 4 points each answer (2 for the explanation and 2 for the graphs) For the following problem use the Three graphs we have developed that show (a) the relationship between savings and investment and r*in the ROW, (b) the relationship between the S and I and the r* in the SOE, and (c), the relationship between the real exchange rate and the level of net exports in SOE, Start from a ion of trade balance (NX=0) for each of the following scenarios and show the result for the trade balance, the relationship between Sand I, and the level of NX in the SOE. A rise in investment demand in the SOE A rise in investment demand in the ROW A fall in the marginal propensity to consume in the ROW A rise in taxes in the SOE A war breaks out among major economies in the ROW A sudden rise in income growth in the ROW.
