Question 1
Which of the following represents the largest component of
international economic transactions for most developed nations?
A) Foreign direct investment
B) Portfolio investment
C) International trade of goods and services
D) Sovereign debt relief
Answer: C) International trade of goods and services
Rationale: International trade of goods and services remains
the bedrock of global economic interactions, traditionally
,making up the largest share of routine cross-border
economic transactions.
Chapter 2: World Trade: An Overview
Question 2
According to the Gravity Model of international trade, the two
most important factors determining the volume of trade between
two countries are:
A) Distance and cultural similarities
B) GDP sizes and geographic distance
C) Trade agreements and common currencies
D) Labor productivity and capital endowments
Answer: B) GDP sizes and geographic distance
Rationale: The Gravity Model dictates that the volume of trade
between two nations is directly proportional to the product of
their GDPs (economic mass) and inversely proportional to
the physical distance between them.
Question 3
Which of the following anomalies or departures from the standard
Gravity Model is typically caused by historic colonial ties or
preferential trade agreements?
A) Negative trade balances
B) Lower trade volume despite close proximity
C) Higher-than-predicted trade volumes between distant nations
D) Absolute decline in service trade
Answer: C) Higher-than-predicted trade volumes between distant
nations
Rationale: Cultural ties, shared languages, and trade
,agreements (like the historical ties between the UK and
Commonwealth nations) often cause countries to trade
significantly more than their physical distance and GDP size
alone would predict.
Chapter 3: Labor Productivity and Comparative Advantage:
The Ricardian Model
Question 4
In the Ricardian model, the primary source of comparative
advantage and gains from trade between nations is differences in:
A) Capital endowments
B) Labor productivity
C) Consumer preferences
D) Factor abundance
Answer: B) Labor productivity
Rationale: The Ricardian model simplifies international trade
by assuming labor is the only factor of production and that
differences in technology lead to varying levels of labor
productivity, which establishes comparative advantage.
Question 5
If Home requires 2 hours of labor to produce 1 unit of wine and
Foreign requires 6 hours of labor to produce 1 unit of wine, which
of the following statements is true regarding absolute advantage?
A) Foreign has an absolute advantage in wine production.
B) Home has an absolute advantage in wine production.
C) Neither country has an absolute advantage.
D) Absolute advantage cannot be determined without knowing
wage rates.
, Answer: B) Home has an absolute advantage in wine production.
Rationale: Home requires fewer labor hours (2 hours) to
produce a unit of wine compared to Foreign (6 hours),
meaning Home can produce it more efficiently, giving it the
absolute advantage.
Question 6
According to the Ricardian framework, a country will export a
good if the relative world price of that good is:
A) Lower than its internal opportunity cost of production
B) Equal to its internal opportunity cost of production
C) Higher than its internal opportunity cost of production
D) Driven down to zero by foreign competition
Answer: C) Higher than its internal opportunity cost of production
Rationale: A nation stands to gain by exporting a good if the
global marketplace values that good higher (in terms of other
goods) than it costs the nation to produce it domestically in
terms of forgone alternatives.
Chapter 4: Specific Factors and Income Distribution
Question 7
The Specific Factors model demonstrates that international trade
creates winners and losers because:
A) Labor is completely immobile between sectors domestically.
B) Factors specific to the export sector lose income.
C) Factors specific to the import-competing sector lose income.
D) Trade causes overall national welfare to drop.
Answer: C) Factors specific to the import-competing sector lose
income.
