Economics MCQs with Answers and Explanations
Economics MCQs with answers on this page are written for the CSS Economics optional subject (200 marks, two papers), PMS, PPSC and FPSC lecturer economics tests, and university and GAT (Subject) exams. The questions cover the standard syllabus: microeconomics (consumer behavior and indifference curves, elasticity, cost and production, monopoly, oligopoly and game theory), macroeconomics (GDP and national income accounting, the multiplier, IS-LM, inflation and unemployment), money and banking, public finance and taxation, international trade and exchange rates, and economic growth and development.
Examiners repeatedly ask about named theories and conditions, so these economics multiple-choice questions give such topics special attention: the Hicks and Slutsky substitution effects, Nash equilibrium, the Solow model and endogenous growth theory, the Marshall-Lerner condition and the J-curve, the Fisher effect, Wagner's law and the 'impossible trinity'. Every question carries a short explanation of the correct answer.
The substitution effect of a price change according to Hicks is isolated by keeping:
John Hicks isolates the substitution effect by adjusting nominal income to keep the consumer on the same indifference curve (constant utility).
Slutsky’s substitution effect differs from Hicks’s because Slutsky holds constant the consumer’s:
Eugene Slutsky holds purchasing power constant by allowing the consumer to afford the exact original consumption bundle at new prices.
An Engel Curve shows the relationship between:

If the income elasticity of demand for a good is negative, the good is classified as an:
Negative income elasticity means demand decreases as consumer income increases, defining an inferior good.
The Envelope Curve in cost theory refers to the firm’s:
The LRAC curve is called an envelope curve because it envelopes (is tangent to) a series of short-run average total cost (SRATC) curves.

Due to product differentiation and free entry, the demand curve is tangent to the downward-sloping section of LRAC, causing excess capacity.

Asymmetric information leads to Market Failure primarily through:
Information asymmetry between buyers and sellers distorts market outcomes via adverse selection (pre-contract) and moral hazard (post-contract).
Gross National Disposable Income (GNDI) is calculated as Gross Domestic Product plus Net Factor Income from Abroad plus:
GNDI = GDP + Net Factor Income from Abroad + net current transfers from the rest of the world, which is the same as GNI + net current transfers (such as workers' remittances, grants and gifts).

The Ricardian Equivalence Hypothesis asserts that government deficit spending funded by borrowing:
Ricardian equivalence, set out by Robert Barro (1974) building on an idea of David Ricardo, holds that people treat government borrowing as future taxes and save their tax cuts to pay them, so debt-financed spending leaves aggregate demand unchanged.
The Balanced Budget Multiplier (when an increase in government spending is matched by an equal increase in taxes) is equal to:
By Haavelmo's balanced budget theorem, the spending multiplier 1/(1 − MPC) and the tax multiplier −MPC/(1 − MPC) add up to exactly 1, so an equal rise in spending and taxes raises national income by the amount of the rise in spending.
For example, with MPC = 0.8 the spending multiplier is 5 and the tax multiplier is −4.

The Fisher Effect predicts that a 1% increase in expected inflation will lead to a 1% increase in the:
The Fisher Effect states that the nominal interest rate adjusts one-for-one with expected inflation: i ≈ r + πᵉ, where i is the nominal rate, r the real rate and πᵉ expected inflation. So a 1% rise in expected inflation raises the nominal interest rate by about 1%, leaving the real rate unchanged.
