Question 1

What is the difference between sunk costs and opportunity costs?

Accepted Answer

Sunk costs are expenses already paid that cannot be recovered, such as salaries, rent, or nonrefundable deposits. Opportunity costs represent the benefit forgone by choosing one option over another, like investing in marketing instead of computers. While sunk costs are irretrievable past expenses, opportunity costs reflect the value of alternative choices available in the future.

Question 2

Why should sunk costs not influence business decisions?

Accepted Answer

Sunk costs cannot be recovered regardless of future choices, making them irrelevant to rational decision-making. Businesses should focus on present circumstances and future benefits rather than past investments. Continuing to fund a failing project simply because money was already spent ignores better opportunities and wastes additional resources.

Question 3

What is the sunk cost fallacy and how does it affect companies?

Accepted Answer

The sunk cost fallacy occurs when organizations base decisions on past investments rather than future prospects. For example, a software company may continue spending money to salvage a failing project because of resources already invested, even when stopping would be rational. This psychological barrier prevents businesses from cutting losses and reallocating resources to more promising opportunities.

Question 4

How can understanding opportunity cost improve business strategy?

Accepted Answer

Recognizing opportunity costs helps firms evaluate trade-offs between competing investments. When a company spends $100,000 on advanced computers, understanding the opportunity cost—such as foregone marketing or research investments—enables better resource allocation. This awareness supports rational decision-making by comparing the value of chosen options against realistic alternatives.

Question 5

What are examples of sunk costs in business operations?

Accepted Answer

Common sunk costs include salaries already paid, insurance premiums, rent, nonrefundable deposits, and repairs completed. A software company investing $500,000 in developing unsuccessful software incurs a sunk cost. These expenses cannot be recovered and should not influence decisions about whether to continue or abandon projects.

Question 6

How should a company decide whether to continue or abandon a failing project?

Accepted Answer

A rational decision focuses on future prospects rather than past spending. If a project will not succeed, the company should stop funding it regardless of previous investments. Decision-makers should evaluate remaining opportunities and potential returns, considering total fixed total variable and total cost curves to assess whether continuing generates positive future value.

Question 7

Why do businesses struggle to abandon projects despite understanding sunk cost principles?

Accepted Answer

The sunk cost fallacy represents a psychological barrier where people become emotionally attached to failing projects because of invested resources. Even when managers recognize that continuing wastes money, reluctance to abandon previous investments often overrides rational analysis. This cognitive bias causes organizations to ignore better alternatives and persist with unprofitable ventures.
