Macroeconomics 1
Section A: Answer ALL questions |
1. Explain the difference between (1) the demand for domestic goods and (2) the domestic demand for goods. (10 marks, 100 words) |
2. First, write out the expression for the real exchange rate. Second, explain all factors that determine the real exchange rate. (10 marks, 100 words) |
3. First, explain why the money demand curve is downward sloping. Second, explain what factor(s) will cause shifts in the money demand curve. (10 marks, 100 words) |
4. |
Using the following information, derive the Monetary Rule (MR) for this central bank: Loss function: L = (yt − ye )2 + 0.5(πt − πT )2 Phillips Curve: πt = πt−1 + α(yt − ye ) In which a is equal to the last digit of your university registration number. E.g., if your registration number is u2001234, a = 4; if the last digit is 0 then use a = 0.5 instead. (10 marks, show ALL the steps of the calculations) |
5. |
In the Financial Times article “Two-speed pandemic recovery will worsen inequality, World Bank warns” (11 Jan 2022), we can read: “Developing countries will fall further behind the rich world as they struggle to recover from the economic impact of the pandemic owing to the spread of coronavirus variants […]. While output in rich countries will return to its pre-pandemic path by 2023, developing countries will still be an average of 4 per cent below their pre-pandemic trend. […] The feeble rebound from the impact of coronavirus will be especially severe among the most vulnerable countries, […] by next year, output among fragile, conflict affected and small island states will still be 7.5 to 8.5 per cent below its pre-pandemic path.” Use a Lorenz Curve to explain the pre- and post-pandemic levels of world inequality. (10 marks, 100 words, excluding the graph) |
Section B: Answer TWO questions |
6. Assume that an economy is described by: |
IS Curve: Y = 3,600 + 3G − 2T − 150r |
LM Curve: Y = + 100r |
Investment function: I = 1,000 − 50r |
Consumption function: C = 200 + (Y − T) |
Long-run equilibrium output for this economy is 4,000 and the price level is 1. |
(a) Assume that the government spending is fixed at 1,200. The government wants to |
achieve a level of investment equal to 900 and achieve Y = 4,000. What level of r is |
needed for I = 900? What levels of T and M must be set to achieve the two goals? |
What will be the levels of private saving, public saving, and national saving? |
(10 marks, shows ALL the steps of the calculation) |
(b) Now assume that the government wants to cut taxes to 1,000. With G set at 1,200, |
what will the interest rate be at Y = 4,000? What must be the value of M ? What |
will I be? What will be the levels of private, public, and national saving? Explain. |
(15 marks, show ALL the steps of the calculations, 150 words max for the explanation) |
