Part C [8 marks] The following 3 questions (49-56) relate to the information given below. Try to do the questions in order since the answers for some questions depend on the answers to previous questions in the series. Each question is worth 1 mark. Consider the following aggregate expenditure (AE) model of an open economy. Output and factor prices are assumed constant. The government is assumed to have no debt. The model of the economy is given below, where YD is disposable income and Y is national income. Consumption: C = 100 + (D.30)YD Taxes (net of all transfers): T = (0.25}Y Investment: I = 100 Government Spending: G = 200 Exports: X = 60 Imports: [M = (.10)Y The space below is provided for you to keep track of your answers as you work through the series of questions. [Hint You may want to sketch an AE diagram to help with this process]
