Macroeconomic Assignment
Submit answers to all the following questions. Be sure to explain your reasoning clearly and fully and use diagrams where appropriate. The questions are applied and analytical. They can only be answered by the student having knowledge of macroeconomic principles.
1. Consider a macro economy was initially at equilibrium level of real GDP. Using an aggregate demand and aggregate supply diagram or model of the economy, graphically illustrate and discuss the short-run and long-run effects of the following events upon the economy:
(a) The Central Bank within the economy reduces interest rates.
(b) There is an increase in private domestic investment spending.
(c) An increase in international oil prices.
(d) Depreciation in the foreign exchange rate value of the economy's currency.
(e) A fall in real estate prices in the capital cities of the country in question (hint: think of the effect upon one's wealth level)
(f) The country main exports rise in price while the goods the country imports from abroad fall in price i.e. its terms of trade improves in the country' favour.
2. Many people find the current unemployment figures for Australia a bit unbelievable. Why is this? Why might the official statistics be inaccurate?
3. Using the simple Keynesian (J-W) model to assess the implications for equilibrium GDP and the level of savings of an increase in the savings function. What happens to the level of savings? What would happen to equilibrium income if there is a sustained rise in private investment spending?
4. State the difference between:
- Money multiplier and income expenditure multiplier.
- between the interest rate and the exchange rate
- Between the balance of payments deficit and the budget deficit
- between the trade deficit and net foreign debt
5. Assuming that the money market is initially in equilibrium, trace through the effects of a rise in the money supply on the money market on the interest rate and also on output, employment and the price level.
6. Distinguish between ongoing demand-pull and ongoing cost-push inflation. Carefully draw them. Why might it be difficult to establish the extent to which a given rate of inflation is either demand-pull or cost push?
