WK6 Problem Solving Assignment: Aggregate Spending Solve these two problems about aggregate spending: 1. Given the following variables in the open economy aggregate expenditure model, autonomous consumption Co = 200, autonomous investment , = 200, government spending Go = 100, export spending Xo = 100, autonomous import spending Mo = 100, taxes Tp = 0, marginal propensity to consume c1 = 0.8, marginal propensity to invest , = 0.1, and marginal propensity to import m, = 0.15, a. Calculate the equilibrium level of income for the open economy aggregate expenditure model. b. If there is an increase in autonomous import expenditure from 100 to 200 resulting from an increase in the currency exchange rate, calculate the new equilibrium level of income and the value of the multiplier. C. Compared with the original equilibrium in part a, if the government decides to impose taxes T'p of 100, calculate the new equilibrium level of income. 2. Remember that consumption has an autonomous component and is a function of disposable income, Ya, where Ya = Y - Tp
