INTRODUCTION
ECON 528 Final Exam practice materials are designed for advanced economics
students preparing for a comprehensive final assessment. The question bank
emphasizes economic reasoning, quantitative interpretation, model application,
equilibrium analysis, and the ability to evaluate policy and market outcomes rather
than relying solely on memorization. Questions are intentionally constructed at an
advanced level and use realistic scenarios requiring students to identify relevant
economic mechanisms, interpret changes in incentives, and distinguish between
competing explanations.
The bank contains 100 multiple-choice questions covering major areas commonly
encountered in graduate-level economics, including consumer and producer theory,
market equilibrium, elasticity, welfare analysis, externalities, taxation, imperfect
competition, game theory, labor markets, macroeconomic stabilization, monetary and
fiscal policy, international economics, and econometric interpretation. Each question
has four alternatives and one best answer, followed by a detailed rationale explaining
the underlying economic logic and why the alternative choices are less appropriate.
Students can use the questions diagnostically by first answering independently and
then studying the rationale to identify conceptual gaps, mathematical weaknesses, or
incorrect assumptions. The goal is to strengthen analytical reasoning and provide
structured preparation for a demanding economics final.

QUESTIONS 1-100
Q1: A consumer has Cobb-Douglas utility U(x,y)=x0.5y0.5U(x,y)=x^{0.5}y^{0.5},
income of $200, and prices Px=4P_x=4 and Py=2P_y=2. What is the consumer's
optimal quantity of good x?
A) 20
B) 25
C) 40
D) 50
Rationale: With Cobb-Douglas utility having equal exponents, the consumer allocates
one-half of income to each good. Thus $100 is spent on x, giving
x=100/4=25x=100/4=25. A is too low, while C and D imply expenditures on x
exceeding the optimal half-income allocation.
3
, Q2: If the price of a normal good increases while income and all other prices
remain constant, which effect necessarily contributes to a reduction in quantity
demanded?
A) Income effect only
B) Substitution effect only
C) Both the substitution and income effects for a normal good
D) Neither effect
Rationale: A higher price makes the good relatively more expensive, generating a
substitution effect away from it. For a normal good, the resulting reduction in real
purchasing power also lowers demand, creating a negative income effect. Therefore
both effects reduce quantity demanded.
Q3: A firm's production function is Q=K0.4L0.6Q=K^{0.4}L^{0.6}. If both
capital and labor are doubled, what happens to output?
A) Output doubles
B) Output increases by less than 100%
C) Output increases by more than 100%
D) Output doubles
Rationale: The exponents sum to one: 0.4+0.6=10.4+0.6=1. The production function
therefore exhibits constant returns to scale. Doubling both inputs exactly doubles
output.
Q4: A competitive firm faces a market price of $50. Its marginal cost is $20 at 10
units, $35 at 20 units, $50 at 30 units, and $65 at 40 units. At which output level
should it operate in the short run?
A) 10 units
B) 20 units
C) 30 units
D) 40 units
Rationale: A competitive firm chooses output where price equals marginal cost,
provided production is worthwhile. At 30 units, MC=P=$50MC=P=\$50. Producing
beyond that point would make marginal cost exceed price, while producing less would
leave profitable marginal units unproduced.
Q5: Suppose the price elasticity of demand for a product is -0.3. A 10% increase
in price will approximately cause quantity demanded to:
