C211 Global Economics for Managers

Correct Answer:

Absolute advantage, comparative advantage, and Heckscher-Ohlin theory.

Explanation:

The three classical international trade theories explain why countries engage in trade and how they benefit from it. Absolute advantage, introduced by Adam Smith, suggests that countries should produce goods they can make more efficiently than others. Comparative advantage, developed by David Ricardo, shows that countries gain from specializing in goods in which they have a lower opportunity cost. The Heckscher-Ohlin theory (also known as the factor proportions theory) emphasizes that countries will export goods that use their abundant factors of production intensively. Together, these theories form the foundation of classical trade analysis.

Why Other Options Are Wrong:

Mercantilism, new trade theory, and strategic trade theory

This is incorrect because these represent historical and modern trade approaches rather than the three classical trade theories. Mercantilism focuses on accumulating wealth through trade surpluses, while new trade theory and strategic trade theory are part of modern trade analysis.

Ricardian model, product life cycle theory, and Porter’s diamond model

This is false because while the Ricardian model is related to comparative advantage, the product life cycle theory and Porter’s diamond model are modern theories that explain trade patterns differently and are not part of the classical framework.

Factor proportions theory, competitive advantage, and trade creation

This is incorrect because while the factor proportions theory (Heckscher-Ohlin) is classical, competitive advantage and trade creation are modern or policy-based concepts rather than classical trade theories.

Correct Answer:

Spot transactions, forward transactions, and swap transactions

Explanation:

The three primary types of currency transactions in international finance are spot transactions, forward transactions, and swap transactions. Spot transactions involve the immediate exchange of currencies at the current exchange rate. Forward transactions are agreements to exchange currencies at a predetermined rate on a future date, helping firms hedge against exchange rate risk. Swap transactions combine spot and forward contracts, allowing parties to exchange currencies temporarily and then reverse the transaction at a later date. These transaction types are fundamental tools for managing foreign exchange risk.

Why Other Options Are Wrong:

Spot transactions, future transactions, and option transactions

This is incorrect because "future transactions" is not the standard term; the correct term is "forward transactions." Options are a separate derivative instrument and are not grouped with the three main types of currency transactions in the study guide.

Forward transactions, option transactions, and swap transactions

This is false because it excludes spot transactions, which are a primary form of currency exchange.

Spot transactions, currency options, and future transactions

This is incorrect because currency options are not considered one of the three main transaction types in the study guide, and "future transactions" should be "forward transactions."

Correct Answer:

the norms of professions and industries.

Explanation:

Normative institutions establish standards, rules, and expectations that guide behavior within professions, industries, or societies. They focus on what is considered appropriate or ethical practice rather than codified legal requirements. For example, professional associations may set ethical codes or industry standards that members are expected to follow. Normative institutions shape behavior through social and professional norms rather than through legal enforcement.

Why Other Options Are Wrong:

the ability to obtain the insights of average consumers.

This is incorrect because gaining consumer insights is a market research activity, not the primary concern of normative institutions, which deal with norms and standards.

the laws in a country.

This is false because laws are enforced by formal legal institutions, not normative institutions. Normative institutions influence behavior through social expectations rather than legal mandates.

the progress of technology at a normal pace.

This is incorrect because normative institutions are not focused on technological advancement; they regulate social and professional norms.

the banking industry

This is false because the banking industry is a sector of the economy and not a type of institution that sets behavioral norms. Normative institutions cut across industries rather than being specific to one.

Correct Answer:

Marginal cost helps firms determine the cost of producing one more unit, influencing whether to increase production based on profitability.

Explanation:

Marginal cost is the additional cost incurred from producing one more unit of output. Firms use this information to decide whether increasing production will increase profits. If the marginal revenue from selling an additional unit exceeds the marginal cost, production should increase. Conversely, if the marginal cost exceeds marginal revenue, producing more would reduce profit. Marginal cost analysis is crucial across all market structures, not just perfectly competitive markets, and guides optimal production decisions to maximize profitability.

Why Other Options Are Wrong:

Marginal cost only affects firms in perfectly competitive markets.

This is incorrect because marginal cost considerations are relevant to all firms, including monopolies, oligopolies, and monopolistic competition, when making production decisions.

Marginal cost is irrelevant to production decisions as it only reflects fixed costs.

This is false because marginal cost specifically reflects the additional variable costs of production, not fixed costs, and is highly relevant to decision-making.

Marginal cost is the total cost divided by the number of units produced, which is used to set prices.

This is incorrect because dividing total cost by output gives the average cost, not marginal cost. Marginal cost focuses on the incremental cost of one additional unit, which directly informs production decisions rather than general pricing.

Explanation

Correct answer: (D.) It decreases.
When a country experiences higher inflation, the purchasing power of its currency decreases relative to other currencies. This typically leads to a depreciation of the currency, meaning its exchange rate declines compared to foreign currencies. Higher inflation makes domestic goods more expensive for foreign buyers and reduces demand for the currency in international markets. Options A and B are incorrect because inflation has a predictable effect, and option C is the opposite of what occurs.

Explanation

Correct answer: (B.) There is high industry pressure to globalize and competitive assets are customized to home markets
The contender strategy is used by firms facing high pressure to globalize while their competitive advantages are primarily tailored to their home market. In this situation, companies may attempt to challenge multinational enterprises (MNEs) in foreign markets by leveraging unique home-market strengths, but they face difficulties because their assets are not easily transferable internationally. This contrasts with strategies for firms whose resources can be applied abroad, which allow more aggressive global expansion.

Correct Answer:

The country's currency is likely to appreciate due to increased foreign investment.

Explanation:

When a country raises its interest rates while other countries keep theirs stable, it tends to attract foreign investors seeking higher returns on investments such as bonds and savings accounts. This increased demand for the country’s currency to make these investments can lead to an appreciation of the currency in the foreign exchange market. Higher interest rates make the country more attractive for capital inflows, strengthening its currency relative to others. This principle is a key concept in international finance and exchange rate determination.

Why Other Options Are Wrong:

The country's currency will depreciate due to increased domestic spending.

This is incorrect because domestic spending alone does not necessarily cause depreciation, and higher interest rates typically reduce domestic borrowing and spending rather than increasing it.

The country's currency will depreciate because of reduced exports.

This is false because while currency appreciation may make exports more expensive, it is the appreciation itself that is the primary effect of higher interest rates, not depreciation due to exports.

The country's currency will remain unchanged regardless of interest rates.

This is incorrect because interest rate differentials are a major driver of currency movements in the foreign exchange market, and rates changes generally do affect currency value.

Correct Answer:

Duopoly

Explanation:

A duopoly is a specific type of oligopoly where the market is dominated by exactly two firms. These two firms hold significant market power and can influence prices, output, and competitive strategies. Because there are only two participants, each firm’s decisions directly affect the other, often leading to strategic behavior such as collusion or price competition. Understanding duopolies is important in industrial organization and competition economics as it highlights the dynamics of limited competition and interdependent decision-making.

Why Other Options Are Wrong:

Oligopoly

While a duopoly is a form of oligopoly, this term refers to markets with a few dominant firms, not specifically two. Using oligopoly would be too broad for this question.

Perfect competition

This is incorrect because perfect competition involves many firms with no single firm able to influence the market price, which contrasts with the two-firm scenario in a duopoly.

Monopoly

This is false because a monopoly refers to a market controlled by a single firm, not two.

Correct Answer:

Exporting involves selling domestically produced goods to foreign markets, while FDI involves investing directly in foreign assets or companies.

Explanation:

Exporting and FDI are two distinct strategies for entering foreign markets. Exporting entails producing goods domestically and selling them abroad, which allows a firm to expand internationally without significant investment in foreign operations. FDI, on the other hand, involves establishing or acquiring assets in a foreign country, such as building a factory, purchasing a company, or investing in local operations. FDI provides greater control over operations, local market access, and potential tax benefits but comes with higher financial risk compared to exporting. Firms choose between these methods based on risk tolerance, control needs, and market opportunities.

Why Other Options Are Wrong:

Exporting requires a local partner, while FDI does not

This is incorrect because exporting does not necessarily require a local partner; it can be done directly through international shipping or intermediaries.

Exporting is less risky than FDI because it does not involve ownership

While partially true, this does not fully describe the fundamental difference between exporting and FDI, which lies in the method of market entry and asset investment.

Exporting is only for services, while FDI is for goods

This is false because exporting applies to both goods and services, and FDI can also involve service-based investments.
