SECTION 1: FOUNDATIONS OF GLOBAL ECONOMICS & ECONOMIC SYSTEMS
(14 Questions)
Q1: Which of the following best describes a mixed economic system?
A. All economic decisions are made by the central government with no private ownership
allowed
B. Economic decisions are based entirely on tradition and customs passed through generations
C. A combination of market forces and government intervention guides resource allocation
[CORRECT]
D. All resources are owned collectively by workers with profits distributed equally
Correct Answer: C
Rationale: A mixed economic system combines elements of both market capitalism (private
ownership, profit motive, price signals) and command/socialist systems (government regulation,
public goods provision, social safety nets). Most modern economies, including the United States,
operate as mixed systems. Option A describes a pure command economy (like North Korea),
Option B describes a traditional economy (found in some indigenous communities), and Option
D describes a theoretical pure socialist or communist system. The key distinction is that mixed
systems recognize market efficiency while allowing government correction of market failures.
Q2: In calculating GDP using the expenditure approach, which of the following represents the
correct formula?
A. GDP = C + I + G + (X + M)
B. GDP = C + I + G + (X − M) [CORRECT]
,2
C. GDP = C + I + G − (X + M)
D. GDP = C + I − G + (X − M)
Correct Answer: B
Rationale: The expenditure approach to GDP calculation sums Consumption (C) by households,
Investment (I) by businesses, Government spending (G), and Net Exports (Exports X minus
Imports M). Imports are subtracted because they represent spending on foreign-produced goods,
not domestic production. Option A incorrectly adds imports rather than subtracting them, which
would overstate domestic production. Option C incorrectly subtracts the sum of exports and
imports, while Option D incorrectly subtracts government spending. Net exports (X − M) can be
positive (trade surplus) or negative (trade deficit).
Q3: A country has an absolute advantage in producing a good when:
A. It can produce the good at a lower opportunity cost than its trading partners
B. It can produce more of the good than another country using the same amount of
resources [CORRECT]
C. It has abundant natural resources specific to that good's production
D. It specializes completely in that good and imports everything else
Correct Answer: B
Rationale: Absolute advantage, first described by Adam Smith in The Wealth of Nations (1776),
refers to the ability to produce more output per unit of input compared to another producer. It is a
productivity concept based on actual output quantities. Option A describes comparative
advantage (David Ricardo's concept), which focuses on opportunity costs and is the basis for
mutually beneficial trade. Option C describes the Heckscher-Ohlin factor endowment theory.
Option D describes complete specialization, which is a result of following comparative
advantage but not the definition of absolute advantage itself.
Q4: Which economic system would most likely experience chronic shortages of consumer
goods due to price controls and lack of profit incentives?
A. Market capitalism
B. Command economy (centrally planned) [CORRECT]
C. Mixed economy with strong regulatory framework
D. Traditional economy based on barter
Correct Answer: B
,3
Rationale: Command economies (centrally planned systems like the former Soviet Union or
contemporary Cuba/North Korea) typically set prices below market-clearing levels for political
reasons, eliminate profit motives that drive efficiency, and misallocate resources based on central
planners' preferences rather than consumer demand. This creates persistent shortages, queues,
and black markets. Market capitalism (A) uses price signals to balance supply and demand.
Mixed economies (C) may have selective shortages in regulated sectors but not chronic
widespread shortages. Traditional economies (D) face scarcity but not the specific structural
shortages caused by price controls.
Q5: According to the theory of comparative advantage, mutually beneficial trade can occur
between two countries when:
A. Both countries have absolute advantages in different goods
B. One country is more efficient at producing all goods than the other
C. Each country specializes in producing goods where it has a lower opportunity cost
[CORRECT]
D. Both countries impose equivalent tariffs to protect domestic industries
Correct Answer: C
Rationale: David Ricardo's theory of comparative advantage (1817) demonstrates that gains
from trade arise from differences in opportunity costs, not absolute productivity. Even if one
country has an absolute advantage in everything (is more productive in all goods), both nations
benefit by specializing according to their comparative advantage (lower relative opportunity
cost) and trading. Option A describes a situation where trade is obviously beneficial but isn't
required for gains from trade. Option B describes absolute advantage, which actually makes
comparative advantage more important (the less productive country must have comparative
advantage in something). Option D describes managed trade, which typically reduces rather than
creates gains from trade.
Q6: In 2026, a developing nation transitions from state-owned enterprises to privatization and
market-based pricing. This represents a shift from:
A. Traditional economy to mixed economy
B. Command economy toward market economy [CORRECT]
C. Market economy toward command economy
D. Mixed economy toward traditional economy
Correct Answer: B
, 4
Rationale: Privatization (transferring state-owned enterprises to private ownership) and market-
based pricing (allowing supply and demand to determine prices rather than central planners) are
hallmark transitions from command/planned economies toward market-oriented systems. This
pattern was seen in post-1989 Eastern Europe, China's reforms starting 1978, and ongoing
transitions in countries like Vietnam. The shift moves decision-making from government
bureaucrats to private actors and market signals. Options A, C, and D describe transitions that do
not match the described policy changes of privatization and price liberalization.
Q7: Which component of GDP would include a U.S. firm's purchase of new robotic assembly
equipment manufactured domestically?
A. Consumption (C)
B. Investment (I) [CORRECT]
C. Government purchases (G)
D. Net exports (X − M)
Correct Answer: B
Rationale: Business fixed investment (machinery, equipment, structures) is a key component of
Gross Private Domestic Investment (I) in GDP accounting. The robotic assembly equipment
represents capital goods that will be used to produce other goods/services over multiple years.
Consumption (A) covers household spending on goods and services. Government purchases (C)
involve spending by federal, state, or local governments. Net exports (D) would only apply if the
equipment were imported (subtracted) or if the firm were exporting it (added). The "domestically
manufactured" aspect confirms it is pure investment with no import component affecting net
exports.
Q8: The opportunity cost of choosing to build a new factory instead of upgrading existing
technology is best defined as:
A. The total monetary cost of constructing the factory
B. The depreciation expense of the new factory over its useful life
C. The value of the upgraded technology benefits that must be forgone [CORRECT]
D. The interest payments on loans used to finance the factory
Correct Answer: C
Rationale: Opportunity cost is the fundamental economic concept of the next-best alternative
foregone when making a decision. It is not merely accounting costs (explicit monetary outlays)
but includes implicit costs of alternatives sacrificed. Here, by choosing the factory, the firm gives
up the benefits (increased efficiency, productivity gains, cost savings) that the technology
