Question 2 Net export (NX =X-IM), where X is export and IM is import. Now assume that the proportion of additional income that is spent on import is 0.1, this is called the marginal propensity to import (mpim)). This is similar to the MPC. Assume that import depends on income such that the total import is IM=0.1(Y) here 0.1 is mpim. Let C=1000+0.5Yd, I=300, G=200, T=100 and X=300. Yd=Y-T+TR and TR=200. Note that T and TR represents Taxes and transfer...
