Introduction
The purpose of this comprehensive professional-level examination bank is to rigorously assess student
mastery of intermediate macroeconomic concepts, principles, and applications as taught in Econ 2030 at
Louisiana State University under Dr. Charles Roussel. This assessment evaluates foundational
theoretical knowledge, applied economic calculation proficiencies, and regulatory frameworks governing
monetary and fiscal institutions. Through a blend of technical multiple-choice items and complex
scenario-based applications, candidates must demonstrate analytical critical thinking and real-world
economic decision-making capabilities. Topics emphasize the operational mechanics of central banking,
financial markets, and price stability indicators necessary for advanced professional fluency.
SECTION ONE: QUESTIONS 1–100
A country's nominal GDP grows by 8% in a single year, while its GDP deflator increases from 110
to 115.5. What is the approximate real economic growth rate experienced by this country during the
, year?
A. 2.5%
B. 3.0%
C. 5.0%
D. 8.0%
🟢 B. 3.0%
🔴 RATIONALE: The GDP deflator increased by 5% (calculated as (115.5 - 110) / 110 = 0.05). Using the
standard macroeconomic approximation formula where Real GDP Growth equals Nominal GDP Growth
minus Inflation (measured by the deflator), we get 8% - 5% = 3%.
An economy produces only two goods: digital tablets and organic apples. In the base year, 100
tablets are sold at $200 each, and 5,000 apples are sold at $1 each. In the current year, 120
tablets are sold at $220 each, and 6,000 apples are sold at $1.50 each. If a fixed basket for the
Consumer Price Index contains 100 tablets and 5,000 apples, what is the CPI for the current year?
A. 110.0
B. 118.0
C. 122.0
D. 125.0
🟢 B. 118.0
🔴 RATIONALE: Base year basket cost = (100 * $200) + (5,000 * $1) = $20,000 + $5,000 = $25,000.
Current year cost of the identical base basket = (100 * $220) + (5,000 * $1.50) = $22,000 + $7,500 =
$29,500. CPI = ($29,500 / $25,000) * 100 = 118.0.
Under the Bureau of Labor Statistics (BLS) standards, how would an individual who was laid off
from an automotive assembly plant three weeks ago, but is currently receiving severance pay and
waiting to be recalled by their employer next week, be classified?
A. Employed
B. Unemployed
C. Discouraged worker
,D. Not in the labor force
🟢 B. Unemployed
🔴 RATIONALE: Individuals who are on temporary layoff and expect to be recalled to their jobs are
classified as unemployed by the BLS, regardless of whether they are receiving severance payments or
actively seeking other employment.
If a commercial banking institution operating within the Federal Reserve System holds $80 million
in demand deposits and faces a mandatory reserve requirement ratio of 12.5%, what is the
maximum potential expansion of the total money supply if the bank currently holds zero excess
reserves and receives a new cash deposit of $10 million?
A. $10 million
B. $70 million
C. $80 million
D. $100 million
🟢 C. $80 million
🔴 RATIONALE: The simple money multiplier is calculated as 1 / Required Reserve Ratio = .125 =
8. The cash deposit represents new reserves. The maximum expansion of the money supply equals the
injection of new reserves multiplied by the money multiplier: $10 million * 8 = $80 million.
According to the classical dichotomy and the principle of monetary neutrality, which of the following
economic aggregates will change if the central bank doubles the money supply overnight?
A. Real GDP
B. Nominal wages
C. The real interest rate
D. Total employment
🟢 B. Nominal wages
🔴 RATIONALE: The classical dichotomy states that nominal variables (measured in monetary units)
, and real variables (measured in physical units) are completely separate. Doubling the money supply
doubles nominal variables like prices and nominal wages, leaving real variables unchanged.
A manufacturing firm buys $25,000 worth of steel and $5,000 worth of specialized components
from domestic suppliers to produce an industrial tractor. The firm sells the completed tractor to a
local agricultural enterprise for $45,000. How much does this series of transactions contribute
directly to the Gross Domestic Product (GDP)?
A. $15,000
B. $45,000
C. $50,000
D. $75,000
🟢 B. $45,000
🔴 RATIONALE: GDP measures only the market value of final goods and services produced within an
economy to avoid double-counting. The intermediate transactions (steel and components) are fully
embedded within the final $45,000 market value of the tractor.
If a country's national saving exceeds its domestic investment, what must be true regarding its net
capital outflow (NCO) and its net exports (NX)?
A. NCO is negative, and NX is negative.
B. NCO is positive, and NX is negative.
C. NCO is negative, and NX is positive.
D. NCO is positive, and NX is positive.
🟢 D. NCO is positive, and NX is positive.
🔴 RATIONALE: By national income accounting identities, National Saving (S) minus Domestic
Investment (I) equals Net Capital Outflow (NCO), which is structurally identical to Net Exports (NX). If S >
I, then S - I > 0, making both NCO and NX positive.
An investor purchases a corporate bond with a fixed nominal interest rate of 7.5% per annum. If the
actual inflation rate over the course of the year turns out to be 3.8% rather than the expected
inflation rate of 2.5%, what is the realized real interest rate for the investor?
