Answer

Export of crude oil matches Visible Trade Account; Payment for international freight services matches Invisible Trade Account; Foreign direct investment into domestic real estate matches Capital and Financial Account.

Tangible merchandise like crude oil is recorded in the visible trade section of the current account. Services such as shipping and freight are intangibles recorded in the invisible trade section of the current account. Financial movements such as foreign direct investments involve capital asset creation and belong to the capital and financial account.

Step-by-Step Solution

1

Identify the nature of the transaction for Export of crude oil.

Crude oil is a physical, tangible commodity (merchandise).

Tangible exports and imports are classified as visible trade in the Current Account.

2

Identify the nature of the transaction for Freight services payment.

Shipping/freight is a service (intangible item).

Intangible service transactions are classified as invisible trade in the Current Account.

3

Identify the nature of Foreign direct investment.

FDI involves international capital movement and ownership of physical assets/capital.

Long-term investment flows and ownership of foreign assets belong to the Capital and Financial Account.

Question 2Question →

Match each classical theory of international trade on the left with its defining principle or primary economist on the right.

Click a left item, then click its matching right item

Show answer & explanation

Answer

Theory of Absolute Advantage pairs with Adam Smith's concept of producing goods using fewer resources; Theory of Comparative Advantage pairs with David Ricardo's relative efficiency and lower opportunity cost principle; Opportunity Cost Theory of Trade pairs with Gottfried Haberler's evaluation of trade using foregone output.

The Theory of Absolute Advantage is correctly matched to Adam Smith because he pioneered the idea of trade driven by absolute productivity differences. The Theory of Comparative Advantage is correctly matched to David Ricardo, who proved trade benefits arise from comparative lower opportunity costs. The Opportunity Cost Theory of Trade is correctly matched to Gottfried Haberler, who replaced the classical labor theory of value with opportunity cost analysis.

Step-by-Step Solution

1

Identify the economist and core concept associated with absolute advantage.

Adam Smith established that countries gain by specializing in products they produce more efficiently in absolute terms.

This establishes the historical foundation of free trade based on absolute cost differences.

2

Identify the economist and core concept associated with comparative advantage.

David Ricardo showed that relative efficiency (lower opportunity cost) determines mutually beneficial trade.

Comparative advantage extends trade theory to situations where one country holds an absolute advantage across all commodities.

3

Identify the modern refinement based on opportunity cost.

Gottfried Haberler reformulated comparative advantage using production possibility curves and opportunity costs rather than labor hours.

This modernizes classical trade theory by removing the restrictive assumption of the labor theory of value.

Question 3Question →

Governments frequently implement commercial policies to regulate international trade and protect domestic industries. Which of the following trade policy instruments refers to a direct financial grant or tax concession granted by the government to domestic producers to lower their production costs and boost exports?

An export subsidy

An import quota

A protective tariff

A trade embargo

Show answer & explanation

Answer: An export subsidy

Answer

An export subsidy is a financial incentive paid by the government to domestic producers to lower production costs and encourage export sales.

An export subsidy is a direct or indirect financial aid (such as cash grants, low-interest loans, or tax relief) paid by the government to domestic producers, allowing them to reduce selling prices and increase competitiveness abroad.

Step-by-Step Solution

1

Identify the key characteristics of the commercial policy instrument described in the question.

The instrument involves government financial assistance given directly to domestic producers to lower costs and encourage exports.

Commercial policy uses various monetary and quantitative instruments to influence trade flows.

2

Evaluate the choices based on economic definitions of trade barriers.

Tariffs are import taxes, quotas are physical volume limits, embargoes are total trade bans, while subsidies are direct financial payments to domestic producers.

Distinguishing between price-based tax instruments, quantitative restrictions, and direct financial subsidies ensures accurate identification of commercial policy tools.

Click a left item, then click its matching right item

Show answer & explanation

Answer

Currency and Payment Systems matches with requiring foreign exchange transactions and creates exposure to exchange rate fluctuations; Mobility of Factors of Production matches with labor and capital facing legal, political, and cultural obstacles across national boundaries; Trade Restrictions and Tariffs matches with sovereign governments imposing customs duties, import quotas, and foreign exchange controls; Transport and Logistics Documentation matches with involving complex shipping paperwork such as bills of lading.

Each feature of international trade differs fundamentally from domestic trade because of distinct political jurisdictions, independent monetary authorities, border controls, and geographical distances.

Step-by-Step Solution

1

Analyze the monetary dimension distinguishing international trade from domestic trade.

Identify that foreign trade crosses currency zones, requiring exchange conversion and introducing currency risks.

Domestic trade operates within a single national currency regime.

2

Evaluate factor mobility across national borders versus within domestic territories.

Recognize that immigration restrictions, capital controls, and legal frameworks hamper international mobility of labor and capital.

Factors of production are significantly more mobile within a nation's borders than internationally.

3

Examine commercial regulations and sovereign trade policy.

Connect foreign trade to governmental interventions like tariffs, import quotas, and exchange controls.

Independent sovereign states regulate foreign goods to protect local industries or manage balance of payments.

4

Assess freight logistics and administrative requirements.

Link international shipping distances and customs jurisdictions to specialized documentation requirements like bills of lading.

Cross-border movements require legal verification of ownership, origin, and duty payments.

Question 5Question →

The table below shows the output of Cocoa and Textiles produced per unit of labor in Country X and Country Y:

Country	Cocoa (tons)	Textiles (meters)
Country X	10	20
Country Y	6	18

Based on the law of comparative advantage, which of the following specialization decisions is mutually beneficial for both countries?

Country X should specialize in Cocoa, while Country Y should specialize in Textiles.

Country X should specialize in both commodities because it holds an absolute advantage in both.

Country Y should specialize in Cocoa because its opportunity cost of producing Cocoa is lower than Country X's.

Country X should specialize in Textiles because the monetary price of Textiles is lower in Country X.

Show answer & explanation

Answer: Country X should specialize in Cocoa, while Country Y should specialize in Textiles.

Answer

Country X should specialize in Cocoa, while Country Y should specialize in Textiles.

To maximize international gains from trade, countries specialize according to comparative advantage (lowest opportunity cost). Country X sacrifices only 2 meters of Textiles per ton of Cocoa, compared to Country Y's sacrifice of 3 meters. Thus, Country X has a comparative advantage in Cocoa. Conversely, Country Y sacrifices only 0.33 tons of Cocoa per meter of Textiles, compared to Country X's 0.5 tons, giving Country Y a comparative advantage in Textiles.

Step-by-Step Solution

1

Calculate the opportunity cost of producing 1 unit of Cocoa for each country.

Country X: 10 tons Cocoa = 20 meters Textiles → 1 ton Cocoa costs

20 / 10 = 2

meters Textiles.
Country Y: 6 tons Cocoa = 18 meters Textiles → 1 ton Cocoa costs

18 / 6 = 3

meters Textiles.

Lower opportunity cost indicates comparative advantage in Cocoa production.

2

Calculate the opportunity cost of producing 1 unit of Textiles for each country.

Country X: 20 meters Textiles = 10 tons Cocoa → 1 meter Textile costs

10 / 20 = 0.5

tons Cocoa.
Country Y: 18 meters Textiles = 6 tons Cocoa → 1 meter Textile costs

6 / 18 = 0.33

tons Cocoa.

Lower opportunity cost indicates comparative advantage in Textile production.

3

Determine specialization based on comparative advantage.

Country X has a lower opportunity cost for Cocoa (

2 < 3

) and should specialize in Cocoa. Country Y has a lower opportunity cost for Textiles (

0.33 < 0.5

) and should specialize in Textiles.

Both nations gain when each specializes in the commodity in which it holds a comparative advantage.

Click a left item, then click its matching right item

Show answer & explanation

Answer

Currency Devaluation matches Expenditure-switching policy; Increase in Direct Income Tax matches Expenditure-reducing policy; Import Quota Imposition matches Direct commercial control policy.

Currency devaluation is an expenditure-switching policy because it alters relative prices to divert spending from imports to home-produced goods. Increasing direct taxation is an expenditure-reducing policy because it lowers disposable income and aggregate demand. An import quota is a direct commercial control because it places a legal quantitative ceiling on imports.

Step-by-Step Solution

1

Analyze Currency Devaluation

Devaluation alters relative prices by raising foreign currency exchange costs for domestic buyers while lowering foreign price of home exports.

Measures altering price ratios to shift demand between foreign and home goods are expenditure-switching policies.

2

Analyze Increase in Direct Income Tax

Higher taxation lowers households' disposable income, compressing overall national expenditure including import demand.

Measures aimed at dampening aggregate domestic expenditure and demand are expenditure-reducing policies.

3

Analyze Import Quota Imposition

A quota sets a legal quantity restriction on imported products entering the home market.

Administrative rules directly controlling trade volumes constitute direct commercial controls.

Question 7Question →

The table below details the international economic transactions recorded for a country in a financial year:

Transaction Item	Value ($ Million)
Export of merchandise goods	450
Import of merchandise goods	600
Shipping and insurance receipts	110
Foreign tourism expenditure by citizens	70
Foreign direct investment inflow	150
Net unrequited transfers received	30

Based on the data provided, what is the country's Current Account balance for the year?

Deficit of $80 million

Surplus of $70 million

Deficit of $150 million

Deficit of $110 million

Show answer & explanation

Answer: Deficit of $80 million

Answer

Deficit of $80 million

The Current Account of the Balance of Payments consists of three primary components: visible merchandise trade, invisible trade (services), and net unrequited transfers. Calculating each gives: Visible Balance =

450m -

600m = -

150m; Invisible Balance =

110m -

70m = +

40m; Net Transfers = +

30m. Adding these together: -

150m +

40m +

30m = -

80m (a deficit of

80 million). Foreign direct investment is excluded as it belongs in the financial account.

Step-by-Step Solution

1

Calculate the Balance of Visible Trade (Merchandise Trade Balance)

Export of merchandise (

450 million) - Import of merchandise (

600 million) = -

150 million (Deficit of

150 million)

Visible trade includes only physical goods exported and imported.

2

Calculate the Balance of Invisible Trade (Services Balance)

Shipping and insurance receipts (

110 million) - Tourism expenditure abroad (

70 million) = +

40 million (Surplus of

40 million)

Invisible trade accounts for service receipts and service payments.

3

Sum all Current Account components (Visible Trade + Invisible Trade + Net Transfers)

-

150 million +

40 million +

30 million = -

80 million (Deficit of $80 million)

The Current Account consists of merchandise trade, services, and net unilateral transfers. Capital flows such as foreign direct investment belong exclusively to the financial/capital account.

Match each theory or concept of international trade on the left with its corresponding principle or theoretical foundation on the right.

Click a left item, then click its matching right item

Show answer & explanation

Answer

Theory of Absolute Advantage matches with Adam Smith's principle of lower total resource input; Theory of Comparative Advantage matches with David Ricardo's relative opportunity cost model; Opportunity Cost Approach matches with Gottfried Haberler's PPC reformulation; Limits of Mutually Beneficial Terms of Trade matches with the range bounded by domestic opportunity cost ratios.

Each trade theory is paired correctly with its seminal economist and core principle: Adam Smith with absolute resource efficiency, David Ricardo with relative opportunity cost, Gottfried Haberler with the PPC opportunity cost reformulation, and terms of trade bounds with internal domestic ratio limits.

Step-by-Step Solution

1

Identify the primary author and principle behind classical absolute advantage.

Adam Smith proposed absolute advantage based on producing more output per unit of resource.

This establishes the historical foundation of free trade theory based on absolute cost superiority.

2

Differentiate Ricardian comparative advantage from absolute advantage.

David Ricardo showed that relative opportunity cost determines specialization and trade gains.

Even if one country has an absolute advantage in all goods, trade remains beneficial based on relative cost differences.

3

Associate the opportunity cost refinement with its proponent.

Gottfried Haberler substituted the rigid labor theory of value with opportunity cost concepts.

This allowed trade theory to account for multiple factors of production using marginal analysis.

4

Determine the conditions for equilibrium terms of trade.

The terms of trade must lie between the domestic cost ratios of both trading partners.

If terms of trade fall outside these bounds, at least one nation would be worse off trading than remaining self-sufficient.

Question 9Question →

Which of the following policy measures is an example of an expenditure-switching policy used to correct a balance of payments deficit?

Currency devaluation

Raising the central bank rediscount rate

Increasing personal income tax rates

Reducing government spending on public works

Show answer & explanation

Answer: Currency devaluation

Answer

Currency devaluation

Currency devaluation changes relative price ratios by making foreign imports relatively more expensive and domestic exports cheaper, causing both local and foreign consumers to switch their demand toward domestically produced goods.

Step-by-Step Solution

1

Understand the mechanism of expenditure-switching policy.

Expenditure-switching policies alter the relative prices of foreign and domestic goods, redirecting consumer spending away from imports and toward domestically produced alternatives.

Correcting a balance of payments deficit requires either lowering total domestic demand (expenditure-reducing) or redirecting demand toward local products (expenditure-switching).

2

Evaluate currency devaluation as a balance of payments adjustment tool.

Devaluation raises the price of foreign goods in terms of local currency while lowering the foreign-currency price of exports, effectively switching domestic and foreign expenditure toward local goods.

Changing foreign exchange rates directly alters price relative ratios between domestic goods and foreign imports.

Question 10Question →

A developing country experiences a persistent balance of payments deficit. To limit foreign exchange expenditure on luxury motor vehicles without levying an indirect tax on their importation, the trade ministry fixes a physical maximum of 5,000 vehicles allowed into the country per calendar year. Which commercial policy instrument has the government introduced?

A quantitative import quota

An ad valorem import duty

A total trade embargo

An export promotion grant

Show answer & explanation

Answer: A quantitative import quota

Answer

A quantitative import quota is the commercial policy instrument introduced.

The correct option correctly identifies the policy as a quantitative import quota because the government specifies a fixed maximum volume (5,000 units per year) of a commodity that can legally enter the country, directly limiting supply rather than using price-based taxes like tariffs.

Step-by-Step Solution

1

Analyze the nature of the trade policy measure

The measure establishes a physical limit of 5,000 units on luxury vehicle imports without charging a customs duty or tax.

Commercial policy instruments are distinguished by whether they manipulate prices (tariffs), quantities (quotas), prohibitions (embargoes), or production costs (subsidies).

2

Map the specific policy characteristic to commercial trade terminology

Direct volume/physical caps on imported commodities are classified as quantitative import quotas.

Import quotas regulate the maximum physical quantity or value of a commodity permitted into a nation over a specified timeframe.

Question 11Question →

Country Y recorded visible exports of $\$600\text{ million}$ and visible imports of $\$850\text{ million}$ during a financial year. Its invisible exports (services rendered abroad) totaled $\$250\text{ million}$ , while its invisible imports (services received) stood at $\$100\text{ million}$ . What is Country Y's current account balance in millions of dollars? (Note: Express a deficit as a negative value, e.g., -100).

Show answer & explanation

Answer: -100

Answer

The current account balance is

-\$100\text{ million}

(a current account deficit of

\$100\text{ million}

).

The Current Account balance combines net visible trade (goods) and net invisible trade (services). Net visible trade is

\$600\text{ million} - \$850\text{ million} = -\$250\text{ million}

(a trade deficit). Net invisible trade is

\$250\text{ million} - \$100\text{ million} = +\$150\text{ million}

(a services surplus). Adding these yields

-\$250\text{ million} + \$150\text{ million} = -\$100\text{ million}

, representing a overall Current Account deficit of

\$100\text{ million}

.

Step-by-Step Solution

1

Calculate the visible trade balance (Balance of Trade).

Visible balance =

\$600\text{ million} - \$850\text{ million} = -\$250\text{ million}

.

Visible trade balance equals earnings from visible exports minus payments for visible imports.

2

Calculate the invisible trade balance.

Invisible balance =

\$250\text{ million} - \$100\text{ million} = +\$150\text{ million}

.

Invisible balance equals receipts from services rendered abroad minus payments for services received.

3

Combine visible balance and invisible balance to get the Current Account balance.

Current Account Balance =

-\$250\text{ million} + \$150\text{ million} = -\$100\text{ million}

.

The Current Account comprises both the trade balance in visible goods and the balance on invisible services and transfers.

Click a left item, then click its matching right item

Show answer & explanation

Answer

Ad Valorem Tariff matches with 'A percentage duty charged based on the monetary value of imported goods'. Import Quota matches with 'A physical restriction setting the maximum quantity of a product allowed into a country'. Export Subsidy matches with 'Government financial assistance paid to domestic firms to lower prices in international markets'. Trade Embargo matches with 'A complete legal restriction prohibiting commercial trade with a targeted nation or product line'.

Each commercial policy tool correctly aligns with its characteristic definition: ad valorem tariffs scale with commodity value, quotas establish quantitative volume caps, export subsidies lower export production costs through government grants, and embargoes serve as absolute trade bans.

Step-by-Step Solution

1

Analyze the operational mechanism of an Ad Valorem Tariff.

It imposes a tax proportional to the value of the imported product rather than a fixed monetary amount per physical unit.

Ad valorem means 'according to value'.

2

Analyze the functional definition of an Import Quota.

It limits the physical quantity or volume of foreign goods allowed entry.

Quotas regulate trade volumes directly rather than through price adjustments.

3

Analyze the purpose of an Export Subsidy.

It provides state funding to local businesses selling products abroad.

Subsidies reduce production costs so domestic exporters can sell at lower prices globally.

4

Analyze the scope of a Trade Embargo.

It represents an absolute prohibition on economic exchange.

Embargoes eliminate trade entirely for political, economic, or security objectives.

Question 13Question →

To correct a persistent balance of payments deficit, a central bank decides to adopt an expenditure-reducing monetary measure. Which of the following actions directly achieves this objective?

Raising the bank rate to contract credit and lower total domestic demand

Lowering the cash reserve ratio to expand liquidity available to commercial banks

Subsidizing local manufacturers to promote export substitution over foreign market entry

Reclassifying foreign direct investment inflows from the financial account into the current account

Show answer & explanation

Answer: Raising the bank rate to contract credit and lower total domestic demand

Answer

Raising the bank rate to contract credit and lower total domestic demand

Expenditure-reducing monetary policies aim to dampen aggregate domestic demand. Raising the bank rate leads to higher interest rates across the banking system, restricting credit creation and reducing general spending, which in turn reduces expenditure on imported goods.

Step-by-Step Solution

1

Identify the goal of the policy measure

The goal is to correct a balance of payments deficit via an expenditure-reducing monetary policy.

Expenditure-reducing policies target aggregate domestic expenditure to curb total spending, including spending on foreign goods.

2

Evaluate the monetary policy tools presented

Raising the bank rate is a contractionary monetary policy that discourages borrowing and dampens consumer and investor spending.

Higher interest rates reduce disposable income and loan availability, leading directly to reduced import spending.

Question 14Question →

The table below shows the input requirement in labor-hours needed to produce one unit of Wheat and one unit of Solar Panels in Country Alpha and Country Beta:

Country	Wheat (1 unit)	Solar Panels (1 unit)
Country Alpha	4 labor-hours	8 labor-hours
Country Beta	6 labor-hours	18 labor-hours

Based on the principle of comparative advantage, which of the following statements correctly identifies the specialization pattern for both countries and the mutually beneficial terms of trade range for 1 unit of Solar Panels?

Country Alpha specializes in Solar Panels, Country Beta specializes in Wheat, and 1 Solar Panel exchanges for between 2 and 3 units of Wheat.

Country Alpha should produce both goods because it has an absolute advantage in both, while Country Beta should not engage in international trade.

Country Beta specializes in Solar Panels and Country Alpha specializes in Wheat because Beta requires more total labor-hours for industrial production.

Country Alpha specializes in Solar Panels, Country Beta specializes in Wheat, and 1 Solar Panel exchanges for between 0.33 and 0.50 units of Wheat.

Show answer & explanation

Answer: Country Alpha specializes in Solar Panels, Country Beta specializes in Wheat, and 1 Solar Panel exchanges for between 2 and 3 units of Wheat.

Answer

Country Alpha specializes in Solar Panels, Country Beta specializes in Wheat, and 1 Solar Panel exchanges for between 2 and 3 units of Wheat.

Country Alpha needs 8 labor-hours for 1 Solar Panel and 4 labor-hours for 1 Wheat, meaning 1 Solar Panel costs 2 units of Wheat. Country Beta needs 18 labor-hours for 1 Solar Panel and 6 labor-hours for 1 Wheat, meaning 1 Solar Panel costs 3 units of Wheat. Alpha has a lower opportunity cost in Solar Panels and should specialize in them, while Beta has a lower opportunity cost in Wheat (0.33 Solar Panels vs 0.5 Solar Panels) and should specialize in Wheat. For trade to benefit both nations, 1 Solar Panel must buy more Wheat than Alpha can produce internally (2 units) but less than Beta must forego internally (3 units).

Step-by-Step Solution

1

Calculate domestic opportunity costs for Country Alpha

Opportunity cost of 1 unit of Wheat = 4/8 = 0.5 Solar Panels. Opportunity cost of 1 unit of Solar Panels = 8/4 = 2 units of Wheat.

Input-based opportunity cost is calculated as (Labor-hours for Good X) / (Labor-hours for Good Y).

2

Calculate domestic opportunity costs for Country Beta

Opportunity cost of 1 unit of Wheat = 6/18 = 0.33 Solar Panels. Opportunity cost of 1 unit of Solar Panels = 18/6 = 3 units of Wheat.

This establishes Country Beta's relative cost ratio.

3

Determine comparative advantage for each country

Country Alpha has comparative advantage in Solar Panels (2 Wheat < 3 Wheat). Country Beta has comparative advantage in Wheat (0.33 Solar Panels < 0.5 Solar Panels).

A nation specializes in the good where its opportunity cost is lower.

4

Establish the terms of trade bounds

1 Solar Panel must exchange for more than 2 units of Wheat (Alpha's cost) but less than 3 units of Wheat (Beta's cost).

Terms of trade must lie strictly between the internal opportunity cost ratios of the two trading partners to benefit both.

Question 16Question →

The table below shows the output of Cocoa (bags) and Solar Panels (units) produced per unit of labor in Country A and Country B:

Country	Cocoa (bags)	Solar Panels (units)
Country A	50	25
Country B	40	40

Before trade, each country possesses 10 units of labor and allocates 5 units of labor to Cocoa production and 5 units of labor to Solar Panel production. If both countries decide to specialize completely according to the principle of comparative advantage, what is the net increase in total world output of Cocoa?

Show answer & explanation

Answer: 50

Answer

The net increase in total world output of Cocoa is 50 bags.

Country A has a lower opportunity cost of Cocoa (

0.5

Solar Panels per bag of Cocoa compared to Country B's

1.0

Solar Panel per bag of Cocoa), giving Country A a comparative advantage in Cocoa. Before specialization, world Cocoa production is

(5 \times 50) + (5 \times 40) = 450

bags. Upon complete specialization, Country A uses all 10 labor units to produce

10 \times 50 = 500

bags of Cocoa. The net gain in total world output of Cocoa is

500 - 450 = 50

bags.

Step-by-Step Solution

1

Determine opportunity costs and comparative advantage for Cocoa

Country A's opportunity cost of 1 Cocoa = 0.5 Solar Panels; Country B's opportunity cost of 1 Cocoa = 1.0 Solar Panel. Country A specializes in Cocoa.

Comparative advantage belongs to the country with the lower opportunity cost in producing that commodity.

2

Calculate initial total world output of Cocoa before specialization

Country A:

5 \text{ labor units} \times 50 = 250 \text{ bags}

; Country B:

5 \text{ labor units} \times 40 = 200 \text{ bags}

. Total initial Cocoa output = 450 bags.

Each country initially allocates half of its 10 labor units (5 units) to Cocoa production.

3

Calculate total world output of Cocoa after complete specialization

Country A:

10 \text{ labor units} \times 50 = 500 \text{ bags}

; Country B: 0 bags. Total post-specialization Cocoa output = 500 bags.

Country A devotes all 10 labor units to Cocoa production.

4

Calculate the net increase in total world Cocoa output

500 \text{ bags} - 450 \text{ bags} = 50 \text{ bags}

.

Subtract initial aggregate output from post-specialization aggregate output.

An economy records $500 million in merchandise exports,$ 650 million in merchandise imports, $120 million in net invisible receipts, and receives$ 200 million in foreign direct investment. What is the country's Current Account balance?

A deficit of $30 million

A surplus of $170 million

A deficit of $150 million

A surplus of $270 million

Show answer & explanation

Answer: A deficit of $30 million

Answer

A deficit of $30 million

The Current Account measures the flow of goods, services, and primary/secondary income. Here, the visible balance is -

150 million (

500M exports minus

650M imports). Adding the net invisible receipts of

120 million gives a net current account balance of -

30 million, which represents a deficit of

30 million. Foreign direct investment ($200M) is an entry under the capital and financial account.

Step-by-Step Solution

1

Calculate the Balance of Visible Trade

Merchandise Exports (

500M) - Merchandise Imports (

650M) = -$150 million

Visible trade consists strictly of tangible goods exported and imported.

2

Calculate the Current Account Balance

Visible Trade Balance (-

; Gross Barter Terms of Trade matches with

\left(\frac{Q_m}{Q_x}\right) \times 100

.

Each concept correctly maps to its definition and formula: Net Barter Terms of Trade measures price indices (

\% P_x / P_m

), Income Terms of Trade measures capacity to import based on export revenue (

\% P_x / P_m \times Q_x

), Single Factoral Terms of Trade incorporates domestic export productivity (

\% P_x / P_m \times Z_x

), and Gross Barter Terms of Trade measures physical trade quantities (

Q_m / Q_x

).

Step-by-Step Solution

1

Identify the formula for Net Barter Terms of Trade

Net Barter Terms of Trade measures price movement of exports relative to imports:

\left(\frac{P_x}{P_m}\right) \times 100

.

It forms the baseline commodity terms of trade index.

2

Identify the formula for Income Terms of Trade

Income Terms of Trade reflects export purchasing power:

\left(\frac{P_x}{P_m}\right) \times Q_x

.

Multiplying commodity terms of trade by export quantity index (

Q_x

) yields total import capacity derived from exports.

3

Identify the formula for Single Factoral Terms of Trade

Single Factoral Terms of Trade incorporates domestic productivity:

\left(\frac{P_x}{P_m}\right) \times Z_x

.

Z_x

represents the productivity index in the domestic export sector.

4

Identify the formula for Gross Barter Terms of Trade

Gross Barter Terms of Trade evaluates physical quantities of trade:

\left(\frac{Q_m}{Q_x}\right) \times 100

.

Unlike Net Barter TOT which uses prices, Gross Barter TOT compares the total quantity of imports received to exports given up.

Show answer & explanation

Answer

Import Tariff matches with 'A direct tax imposed by government on imported commodities.', Import Quota matches with 'A physical restriction on the maximum quantity...', Trade Embargo matches with 'A complete government ban...', and Export Subsidy matches with 'A financial grant paid to domestic manufacturers...'.

Each trade policy instrument is accurately paired with its defining characteristic: tariffs serve as price-increasing taxes, quotas impose volume limits, embargoes enforce complete commercial bans, and export subsidies provide financial assistance to domestic producers.

Step-by-Step Solution

1

Identify the operational mechanism of an Import Tariff.

Recognize that tariffs act as price-based controls through government taxation on foreign goods.

Tariffs raise import prices to generate government revenue and discourage foreign purchases.

2

Identify the operational mechanism of an Import Quota.

Recognize that quotas set a maximum quantitative ceiling on foreign goods.

Quotas restrict physical import volume directly without changing tax rates.

3

Identify the operational mechanism of a Trade Embargo.

Recognize that an embargo represents a total prohibition of commercial exchange.

Embargoes completely halt bilateral or multilateral trade for economic or diplomatic reasons.

4

Identify the operational mechanism of an Export Subsidy.

Recognize that export subsidies are government payments granted to home exporters.

Subsidies assist domestic firms in offering lower, more competitive pricing internationally.
