WGU Global-Economics-for-Managers Practice Exam Questions & Answers

In Global Economics for Managers, a market shortage occurs when quantity demanded exceeds quantity supplied at the current price. A defining characteristic of a shortage is that quantity supplied is less than the equilibrium quantity, making option D correct.

Shortages typically arise when prices are set below equilibrium, such as under price controls. At these lower prices, consumers demand more, while producers supply less, creating excess demand.

Option A describes a surplus condition. Option B contradicts the definition of shortage. Option C is incorrect because shortages create upward, not downward, pressure on prices.

Thus, option D correctly identifies a characteristic of a market shortage.

In Global Economics for Managers, the fundamental profit-maximization rule states that firms should increase production when marginal revenue exceeds marginal cost, making option C correct.

Marginal revenue represents the additional revenue from selling one more unit, while marginal cost represents the additional cost of producing it. As long as MR > MC, producing additional units increases profit. Firms should stop expanding output when MR = MC.

Option A implies losses on additional units. Option B relates to cost efficiency, not profit maximization. Option D ignores costs and therefore does not maximize profit.

Therefore, option C correctly identifies the condition under which firms should increase production.

A monopoly created by government regulation exists when a single firm receives the exclusive legal right to produce or sell a good or service. Option B is correct because legal exclusivity prevents competitors from entering the market. This may occur through patents, copyrights, licenses, public franchises, or other government-granted rights. Option A describes a natural monopoly, where one firm can serve the entire market at lower cost due to cost structure. Option C describes a resource monopoly, where one firm controls a key input. Option D describes economies of scale, another source of natural monopoly power. Government-created monopoly power differs because entry is restricted by law rather than resource control or production efficiency. Managers must recognize this because legal rights can create strong market power.

In Global Economics for Managers, a first mover is a firm that enters a market early and is often able to erect significant barriers to entry, making option B correct.

First movers can secure scarce resources, establish strong brand recognition, achieve economies of scale, and set technological or industry standards. These advantages make it difficult for later entrants to compete effectively.

Late movers benefit from reduced uncertainty but rarely control key assets. Contenders and dodgers are strategic responses to multinational enterprises, not timing-based entry categories.

Therefore, option B correctly identifies the entrant most capable of erecting significant entry barriers.

In Global Economics for Managers, demand for a good increases when factors other than its own price change in a favorable direction. Two such changes are an increase in the price of a substitute and a decrease in the price of a complement, making options A and B correct.

When the price of a substitute rises, consumers switch toward the relatively cheaper alternative, increasing demand for the good in question. For example, if the price of coffee increases, demand for tea may rise.

When the price of a complement falls, consumers are more likely to purchase both goods together, increasing demand. For instance, a decrease in the price of printers raises demand for printer ink.

Options C and D reduce demand rather than increase it.

Thus, A and B correctly identify changes that increase demand.

When the Federal Reserve decreases the money supply, aggregate demand decreases because borrowing becomes more expensive and less credit is available. Option B is correct because the quantity of goods and services demanded at any given price level falls. A lower money supply tends to raise interest rates, which discourages consumer borrowing, business investment, and interest-sensitive purchases such as homes, vehicles, and capital equipment. This shifts the aggregate demand curve left. Option A is not the standard macroeconomic result. Option C is too narrow and incorrectly states that demand increases. Option D is also incorrect because contractionary monetary policy does not directly increase aggregate demand for imports. For managers, tighter monetary policy can reduce sales forecasts, investment plans, and expansion opportunities.

In Global Economics for Managers, the consumption component of GDP includes household spending on goods and services, making option C correct.

When a person pays for a haircut, it represents a direct purchase of a service by a household. Consumption is the largest component of GDP in most economies and includes spending on nondurable goods, durable goods, and services.

Option A is classified as investment. Option B is government spending. Option D is an export, counted in net exports.

Thus, option C correctly identifies a consumption transaction.
