Free Practice Questions for WGU Global-Economics-for-Managers Exam

According to Global Economics for Managers , when marginal cost exceeds marginal revenue , firms should decrease production , making option D correct.

In this case, MC = $92 and MR = $81. Producing an additional unit would reduce profit because the cost of production exceeds the revenue gained. Reducing output moves the firm closer to the profit-maximizing condition where MR equals MC.

Options A, B, and C would worsen losses or ignore marginal decision-making principles.

Therefore, option D is the correct managerial response.

In Global Economics for Managers , the extender strategy centers on leveraging homegrown competencies abroad , making option A the correct answer. This strategy is typically adopted by firms whose competitive assets are strong and transferable across borders and that operate in industries with significant pressure to globalize.

Homegrown competencies may include proprietary technology, strong brands, efficient production processes, or superior managerial know-how developed in the domestic market. Under an extender strategy, firms take these existing strengths and apply them to foreign markets, often through exporting, licensing, franchising, or foreign direct investment. The goal is to extend the firm’s competitive advantage beyond national borders without fundamentally altering its core business model.

Option B describes a dodger or collaborator strategy , which emphasizes cooperation rather than independent expansion. Option C aligns more closely with a defender strategy , where firms rely on local advantages to resist foreign competition. Option D reflects elements of a contender strategy , where firms prioritize learning before expanding internationally.

The extender strategy is particularly effective when firms face global competitors but already possess assets that can be scaled internationally at relatively low cost. For managers, understanding this strategy is critical for deciding when and how to internationalize operations in response to MNE competition.

Thus, option A accurately reflects the central focus of the extender strategy as defined in Global Economics for Managers .

In Global Economics for Managers , an indifference curve represents all combinations of goods that provide the same level of satisfaction (utility) to a consumer. If Point A and Point B lie on the same indifference curve, the consumer is indifferent between the two bundles, making option B correct.

This means the consumer derives equal satisfaction from either bundle and has no preference for one over the other. Movement along an indifference curve reflects trade-offs between goods while maintaining constant utility.

Options A and D relate to cost, which is irrelevant to indifference curves. Option C is incorrect because preference differences occur only when points lie on different indifference curves.

Thus, option B correctly describes the implication of two points on the same indifference curve.

The institution-based view of global business argues that firm behavior and strategy are shaped by the interaction between firms and institutions. Option A is correct because it captures the central proposition: firms do not make decisions in isolation; they operate within formal and informal institutional constraints. Formal institutions include laws, regulations, property rights, and political systems. Informal institutions include norms, ethics, customs, and cultural expectations. These institutions reduce uncertainty and influence what strategies are acceptable, legitimate, and profitable. Option B is too narrow because institutions include more than government regulation. Option C is incorrect because firms still make strategic choices. Option D is wrong because financial motivations remain important, but they operate within institutional limits.

In Global Economics for Managers , a market economy is characterized by decentralized decision making and reliance on market forces, making options B and E correct.

Option B is correct because Adam Smith , in The Wealth of Nations (1776), laid the intellectual foundation for market economies. He argued that individuals pursuing their own self-interest unintentionally promote the overall welfare of society.

Option E correctly identifies the “invisible hand” , a central concept in market economies. Prices, supply, and demand coordinate economic activity without centralized planning. Firms decide what to produce based on profitability, and consumers decide what to buy based on preferences and prices.

Options A, C, D, and F describe command economies , where governments control production, pricing, and resource ownership—characteristics inconsistent with market economies.

Thus, B and E accurately describe defining features of a market economy.

A key feature of oligopoly is the tension between cooperation and self-interest. Option A is correct because oligopolistic markets contain only a few major sellers, so each firm’s pricing, output, and advertising decisions affect rivals. Firms may benefit collectively from cooperation, such as keeping prices high, but each firm also has an incentive to undercut rivals and gain market share. This creates strategic interdependence. Option B is wrong because oligopoly firms are not independent like perfectly competitive firms; they must anticipate competitor reactions. Option C is also wrong because one seller’s actions can significantly affect other sellers’ profits. Option D is incorrect because oligopoly firms often have strong motivation to cooperate, whether formally or tacitly, though explicit collusion may be illegal.

In Global Economics for Managers , direct exporting allows firms to capitalize on economies of scale in production in the home country , making option B correct.

By concentrating production domestically, firms can achieve lower average costs, maintain quality control, and leverage existing facilities and expertise. Direct exporting avoids the fixed costs of establishing foreign production facilities.

Options A, C, and D are incorrect because exporting typically involves transportation costs, limited distribution control, and exposure to exchange rate risk.

Thus, option B correctly identifies a key advantage of direct exporting.

In Global Economics for Managers , complementary goods have negative cross-price elasticity , making option C correct.

When the price of one good rises, demand for its complement falls. Examples include cars and gasoline or printers and ink.

Substitutes have positive cross-price elasticity. Inferior and luxury goods relate to income elasticity, not cross-price elasticity.

Thus, option C is correct.

In Global Economics for Managers , demand is inelastic when quantity demanded responds only slightly to changes in price , making option B correct.

Inelastic demand is common for necessities, goods with few substitutes, or goods that represent a small portion of income. When demand is inelastic, price and total revenue move in the same direction.

Options A, C, and D describe elastic demand.

Thus, option B correctly defines inelastic demand.

In Global Economics for Managers , deadweight cost (or deadweight loss) is defined as a net loss that occurs in an economy as a result of tariffs or other market distortions , making option D the correct answer. Deadweight cost represents the reduction in total economic surplus—consumer surplus plus producer surplus—that is not offset by gains to any other group, including the government.

When a tariff is imposed on imported goods, domestic prices rise above world prices. As a result, consumers purchase less of the good and pay higher prices, while domestic producers may increase output despite being less efficient than foreign producers. Although the government collects tariff revenue, this revenue does not fully compensate for the loss experienced by consumers and the misallocation of resources. The portion of lost surplus that is not transferred to producers or the government is the deadweight cost.

Option A is incorrect because a government payment to a domestic firm refers to a subsidy , not a deadweight cost. Option B describes an anti-dumping tariff , which is a specific trade policy instrument rather than a definition of deadweight cost. Option C defines opportunity cost , a fundamental economic concept distinct from deadweight loss.

From a managerial perspective, Global Economics for Managers emphasizes that deadweight costs signal economic inefficiency . Tariffs distort price signals, encouraging production in higher-cost domestic industries and discouraging consumption that would otherwise generate value. These inefficiencies reduce overall economic welfare and can lead to retaliation by trading partners, further magnifying losses.

Understanding deadweight cost is essential for managers operating in global markets, as it explains why protectionist policies often reduce national and global welfare despite benefiting specific interest groups. Thus, option D accurately reflects the definition and economic significance of deadweight cost in international trade analysis.
