Figure 1: A hypothetical AD-AS model for Canada
Question 1.1: (Ref. Figure 1) During the 1990s, many stock market investors in Canada became optimistic about information technology and bid up stock prices, especially those of high-tech companies; this was referred to as the "dot-com bubble." However, when the new technologies started to appear less profitable than they had originally seemed, investment spending fell and the prices of many stocks fell sharply, wiping billions of dollars from investors' accounts. For example, from September 2000 to September 2001, the price of Nortel stock fell from more than $120 to less than $10. The stock market crash reduced Canadian household wealth and, in turn, consumer spending.
Show graphically the effects of this stock market crash on the short-run macroeconomic equilibrium. Write briefly all the necessary steps.
Question 1.2: (Ref. Figure 1) Recent fall in the national unemployment rate increased consumer confidence about the future of the economy. Show graphically the effects of each of this fall in the national unemployment rate on the short-run macroeconomic equilibrium. Write briefly all the necessary steps.
Ref. Figure 2: The figure below shows an economy's aggregate demand curve and its short-run and long-run aggregate supply curves (labelled AD, SRAS, and LRAS, respectively). Initially, the economy is in macroeconomic equilibrium.

Question 2.1: (Ref. Figure 2) The government announces that households will pay much higher taxes.
- Show graphically the effect on the short-run macroeconomic equilibrium. Write briefly all the necessary steps.
- What type of output gap do we have in this situation?
- Show graphically the long-run self-correcting mechanism in the economy. Write briefly all the necessary steps.
- Assume that the government uses the fiscal policy to close the output gap. What type of fiscal policy the government should use to close the output gap. Show graphically the effects of the prescribed fiscal policy. Write briefly all the necessary steps.
Question 2.2: (Ref. Figure 2) The year 1979 was a bad year for all oil-importing nations. The overthrow of the Shah of Iran's dictatorship in a popular revolution disrupted world oil markets. The result was a sharp increase in the price of oil. This increase in oil prices greatly affected aggregate supply in oil-importing nations.
- Show graphically the effect on the short-run macroeconomic equilibrium. Write briefly all the necessary steps.
- What type of output gap do we have in this situation?
- Show graphically the long-run self-correcting mechanism in the economy. Write briefly all the necessary steps.
- Assume that the government uses the fiscal policy to close the output gap. What type of fiscal policy the government should use to close the output gap. Show graphically the effects of the prescribed fiscal policy. Write briefly all the necessary steps.
Question3. Question 3.1: For simplicity, let's assume that every household has a marginal propensity to consume (MPC) of 0.75. If the government implements a fiscal policy involving its purchases of goods and services, by how much should government purchases (G) change to increase the GDP by $4trillion?
Question 3.2: For simplicity, let's assume that every household has a marginal propensity to consume (MPC) of 0.75. If the government implements a fiscal policy involving government transfers (TR), by how much should government transfers change to increase the GDP by $4trillion?
Question 3.3: For simplicity, let's assume that every household has a marginal propensity to consume (MPC) of 0.75. What can you conclude about the effect of fiscal policy involving government purchases (question 3.1) and fiscal policy involving government transfers (question 3.2) on aggregate demand?
