In Global Economics for Managers , profit-maximizing firms should increase production when marginal revenue (MR) exceeds marginal cost (MC) , making option A correct.

Here, MR = $200 and MC = $150. Since the additional revenue from producing one more unit exceeds the additional cost, producing that unit increases profit. Firms should continue increasing output until MR equals MC.

Options B, C, and D contradict the marginal decision rule. Reducing or stopping production would forgo profitable opportunities.

Thus, option A is correct.

In Global Economics for Managers , bounded rationality describes the necessity of making sensible decisions without complete information , making option B correct. Because information is costly, limited, or imperfect, individuals and firms cannot always make fully optimal decisions.

Bounded rationality recognizes cognitive limitations and time constraints. Managers often rely on rules of thumb, experience, and simplified models rather than exhaustive analysis. This approach leads to satisfactory decisions rather than perfectly optimal ones.

Option A assumes complete information, which is unrealistic. Options C and D describe information asymmetry problems, not decision-making constraints.

Thus, option B correctly defines bounded rationality.

Informal institutions are unwritten social constraints that shape behavior, including norms, customs, values, traditions, and ethics. Option B is correct because ethics represents an informal guide to behavior rather than a formally codified legal requirement. Informal institutions reduce uncertainty by helping people understand what is socially acceptable, trustworthy, or legitimate in a particular society. They matter greatly in global business because managers may comply with formal laws but still fail if they ignore local customs or ethical expectations. Rules and regulations are usually formal when written and enforced by legal authorities. Written laws are clearly formal institutions. Informal institutions are enforced mainly through social approval, reputation, relationships, and cultural expectations rather than courts or government penalties.

In Global Economics for Managers , an increase in supply with demand held constant leads to a new equilibrium characterized by a lower price and a higher quantity , making option A—quantity increases—the correct answer. This outcome follows directly from standard supply-and-demand analysis.

When supply increases, the supply curve shifts to the right. At the original equilibrium price, producers are now willing and able to supply more than consumers wish to buy, creating excess supply. To eliminate this surplus, sellers reduce prices. As prices fall, quantity demanded increases until a new equilibrium is reached where quantity supplied equals quantity demanded.

Although price also changes (it falls), the question asks what happens to the equilibrium point of price and quantity , and among the given options, only quantity increases is correct. Price does not remain the same, nor does it increase, and quantity certainly does not decrease.

This concept is critical for managers analyzing productivity improvements, technological progress, or reductions in input costs. Supply increases are often driven by innovation, economies of scale, or favorable regulatory changes, all of which allow firms to produce more at every price.

Thus, option A correctly describes the equilibrium outcome when supply increases and demand remains unchanged.

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.

===============

The Federal Reserve alters bank reserve quantities through monetary policy tools such as changing the discount rate and conducting open market operations. Option A is correct because raising the discount rate makes borrowing from the Fed more expensive, which can reduce bank reserves and lending. Option B is correct because buying bonds injects reserves into the banking system; the Fed pays for bonds, increasing bank reserves. Option E is correct because selling bonds removes reserves from the banking system as banks and investors pay the Fed. Raising inflation is not a direct Fed operating tool. Selling stock shares is not how the Fed manages reserves. Raising income tax rates is fiscal policy controlled by government taxation authorities, not the Federal Reserve’s reserve-management tool.

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 , copyright is identified as a form of intellectual property protection that applies to original works of authorship , making option A—the content of a book—the correct answer. Copyright protects the expression of ideas rather than the ideas themselves.

Copyright protection typically covers literary works, music, films, software code, artistic creations, and other original content fixed in a tangible medium. It grants the creator exclusive rights to reproduce, distribute, display, and perform the work for a specified period. This protection encourages creativity and innovation by allowing creators to earn economic returns from their work.

Option B refers to trademarks , which protect brand names, symbols, and slogans used to distinguish goods or services. Option C, the design of a logo, is also generally protected under trademark law. Option D describes a patent , which protects new inventions, processes, or designs with functional utility.

Global Economics for Managers emphasizes that strong intellectual property protection is critical for firms competing in knowledge-intensive industries. Copyright protection, in particular, plays a key role in publishing, entertainment, and software sectors.

Therefore, option A correctly identifies an example of what copyright is used to protect.

In Global Economics for Managers , an oligopoly is defined as a market structure characterized by limited competition in which a small number of sellers dominate the market , making option C the correct answer. These firms collectively control a large share of total market output, and each firm’s actions significantly influence the behavior and profitability of the others.

Oligopolistic markets are common in industries with high barriers to entry, such as automobiles, airlines, telecommunications, and energy. Barriers may include economies of scale, high capital requirements, technological advantages, or government regulation. Because only a few firms operate in the market, strategic decision making becomes critical.

Option A, monopoly, involves a single seller. Option B, monopolistic competition, includes many sellers offering differentiated products. Option D, perfect competition, involves many sellers with no market power.

Global Economics for Managers emphasizes that oligopolies are marked by strategic interaction, where firms must anticipate competitors’ reactions when setting prices, output, advertising, or investment levels. This interdependence distinguishes oligopoly from other market structures.

Thus, option C accurately describes a market structure with limited competition and a small number of sellers.

In Global Economics for Managers , marginal cost (MC) is defined as the increase in total cost that arises from producing one additional unit of output , making option B correct. Marginal cost plays a central role in production and pricing decisions because it reflects the incremental cost of expanding output.

Marginal cost typically includes additional labor, materials, and variable inputs required for one more unit. Fixed costs do not affect marginal cost in the short run because they do not change with output. As production increases, marginal cost may initially decline due to specialization and efficiency gains, but it often rises later because of diminishing marginal returns.

Managers rely on marginal cost to determine optimal output levels. Producing beyond the point where marginal cost exceeds marginal revenue reduces profit. Therefore, understanding marginal cost is essential for profit maximization, cost control, and operational planning.

Thus, option B correctly defines marginal cost.
