Problem 1: GDP Measurement
Which of the following items is directly counted in the current year's Gross Domestic Product (GDP)?
A) A newly built residential house purchased by a homebuyer
B) The resale of a used car produced five years ago
C) Purchase of intermediate microchips used to manufacture laptops
Fact: GDP includes only final goods and services produced within the current time period to avoid double-counting and accurately reflect current economic output.
Problem 2: Real vs. Nominal GDP
What is the primary difference between Real GDP and Nominal GDP?
A) Real GDP excludes net exports from total calculation
B) Real GDP adjusts output for inflation using constant base-year prices
C) Nominal GDP accounts only for government sector spending
Fact: Nominal GDP uses current-year market prices (including inflation), whereas Real GDP uses constant prices from a base year to isolate actual physical growth in production.
Problem 3: Monetary Policy
If a central bank wants to enact contractionary monetary policy to combat high inflation, which action is it most likely to take?
A) Buying government securities on the open market
B) Lowering the reserve requirements for commercial banks
C) Raising its benchmark policy interest rate
Fact: Raising interest rates increases the cost of borrowing for households and businesses, cooling down consumption, investment, aggregate demand, and price inflation.
Problem 4: Types of Unemployment
What type of unemployment occurs when workers lack the specific skills demanded by an evolving economy due to technological change?
A) Frictional Unemployment
B) Structural Unemployment
C) Cyclical Unemployment
Fact: Structural unemployment stems from long-term mismatches between worker skills and available positions, often caused by automation or technological shifts.
Problem 5: Fiscal Policy
Which combination of government actions represents an expansionary fiscal policy designed to stimulate a sluggish economy?
A) Increasing government spending and cutting taxes
B) Reducing government spending and raising taxes
C) Decreasing interest rates and purchasing bonds
Fact: Expansionary fiscal policy directly adds demand through government purchasing and leaves more disposable income with consumers through tax cuts.
Problem 6: Inflation & Purchasing Power
If nominal interest rates are 5% and the annual inflation rate is 3%, what is the approximate real interest rate?
Fact: Under the Fisher Equation, Real Interest Rate ≈ Nominal Interest Rate − Inflation Rate (5% − 3% = 2%).
Problem 7: Money Multiplier
If the reserve requirement set by the central bank is 10%, what is the theoretical maximum simple money multiplier?
Fact: The simple money multiplier formula is 1 / Reserve Requirement. For a 10% (0.10) requirement, 1 / 0.10 = 10.
Problem 8: Aggregate Demand
Which of the following components is NOT part of the Aggregate Demand (AD) expenditure formula?
A) Investment Spending (I)
B) Net Exports (NX)
C) Transfer Payments (TP)
Fact: Aggregate Demand consists of C + I + G + NX. Government transfer payments (like social security) are not direct production purchases and are excluded.
Problem 9: International Trade
According to David Ricardo's principle of comparative advantage, two countries can gain from mutual trade as long as:
A) They have different opportunity costs in producing goods
B) One nation holds an absolute advantage in all goods
C) Trade tariffs and import quotas are actively enforced
Fact: Comparative advantage relies on relative opportunity costs. Specializing where opportunity cost is lower allows both nations to consume beyond their domestic possibilities.
Problem 10: Business Cycles
What macroeconomic phenomenon occurs when an economy experiences stagnant output growth paired with high inflation?
A) Hyperinflation
B) Stagflation
C) Deflationary Spiral
Fact: "Stagflation" combines economic stagnation (recession/high unemployment) with high inflation, often triggered by severe negative supply shocks like sudden energy price spikes.
