Important WGU Global Economics for Managers Exam Questions

Answer: D

Explanation:

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.

Answer: A

Explanation:

A good with close substitutes tends to have elastic demand because consumers can easily switch to another product when its price rises. Option A is correct. Elastic demand means quantity demanded responds strongly to price changes. For example, if one brand of bottled water increases in price and many similar brands are available, consumers can quickly shift purchases. This makes the seller more constrained when raising prices. Goods with few substitutes, necessities, or small budget shares tend to have less elastic demand. Complements affect cross-price relationships, but having many or few complements does not directly define whether demand for the good itself is elastic. Tangibility also does not determine elasticity. For managers, elasticity is critical because it affects pricing strategy, revenue forecasting, and competitive positioning.

Answer: B

Explanation:

In Global Economics for Managers, the bandwagon effect refers to the movement of investors in the same direction at the same time, making option B correct. This phenomenon occurs when individuals follow the actions of others rather than relying solely on their own information or analysis.

The bandwagon effect is common in financial markets, particularly during asset bubbles or currency crises. As more investors buy or sell an asset, others follow, reinforcing the trend regardless of underlying fundamentals. This herd behavior can amplify volatility and lead to mispricing.

Options A, C, and D do not describe collective investor behavior.

Thus, option B correctly defines the bandwagon effect.

Answer: C

Explanation:

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.

Answer: A

Explanation:

An import tariff raises the domestic price of imported furniture, which reduces consumer surplus. Option A is correct. Consumer surplus is the difference between what buyers are willing to pay and what they actually pay. When a tariff increases the market price, consumers pay more and typically buy less. This reduces the benefit consumers receive from participating in the market. Domestic producers may gain producer surplus, and the government may collect tariff revenue, but consumers lose because prices rise and available choices may shrink. Option B is too weak because the standard tariff effect on consumer surplus is a decrease. Option C is wrong because tariffs change prices and quantities. Option D is the opposite of the expected effect. Tariffs redistribute welfare away from consumers.
