Practice Questions & Examples
Multiple Choice Example (Microeconomics)
If the price elasticity of demand for a good is 0.5, a 10% increase in price will result in:
- A 5% decrease in quantity demanded
- A 20% decrease in quantity demanded
- A 5% increase in quantity demanded
- A 20% increase in quantity demanded
Answer: A - Price elasticity of demand = (%ΔQ)/ (%ΔP). If PED = 0.5 and %ΔP = 10%, then %ΔQ = 0.5 × 10% = 5%. Since price increased, quantity demanded decreases by 5%.
Short Answer Example (Macroeconomics)
Explain how expansionary monetary policy affects aggregate demand.
Sample Response: Expansionary monetary policy, such as lowering interest rates, increases aggregate demand through several channels. Lower interest rates reduce the cost of borrowing, encouraging businesses to invest in capital goods and consumers to purchase big-ticket items like homes and cars. This shifts the aggregate demand curve to the right. Additionally, lower rates may depreciate the currency, boosting net exports. The overall effect is increased spending and economic growth.
Graphing Example (Microeconomics)
Draw a supply and demand graph showing the effect of a $2 per unit tax on sellers. Label the original equilibrium, new equilibrium, tax revenue, and deadweight loss.
Graph Description: The tax shifts the supply curve upward by $2. The vertical distance between the original and new supply curves equals the tax amount. The new equilibrium has a higher price (paid by buyers) and lower quantity. Tax revenue is the area of the rectangle formed by the tax amount and quantity sold. Deadweight loss is the triangle above the tax revenue rectangle, representing the efficiency loss from reduced market activity.
Calculation Example (Elasticity)
If the price of coffee increases by 20% and quantity demanded decreases by 15%, what is the price elasticity of demand? Is coffee elastic or inelastic?
Calculation: PED = (%ΔQ) / (%ΔP) = (-15%) / (20%) = -0.75. Since |PED| = 0.75 > 1, coffee is elastic (quantity demanded is relatively responsive to price changes).
Policy Analysis Example (Macroeconomics)
Evaluate the effectiveness of using fiscal policy to combat a recession caused by decreased consumer confidence.
Analysis: Fiscal policy can be effective through increased government spending or tax cuts to boost aggregate demand. During a recession from decreased consumer confidence, expansionary fiscal policy shifts AD rightward, increasing output and employment. However, implementation lags (legislative process) and potential crowding out effects (higher interest rates reducing private investment) are limitations. The spending multiplier effect makes it particularly effective when monetary policy is constrained by the zero lower bound.
