18 Jan How To Recognize Sunk Costs

When making business decisions, organizations should only consider relevant costs, which include future costs—such as decisions about inventory purchase costs or product pricing—that still need to be incurred. Sunk costs are excluded from future business decisions because the cost will remain the same regardless of the outcome of a decision. Emotional attachment in the context of the sunk cost dilemma refers to the emotional investment people or organizations make in a project or decision due to the resources already committed.

Ellingsen, Johannesson, Möllerström and Munkammar[40] have categorised framing effects in a social and economic orientation into three broad classes of theories. Firstly, the framing of options presented can affect internalised social norms or social preferences – this is called variable sociality hypothesis. Secondly, the social image hypothesis suggests that the frame in which the options are presented will affect the way the decision maker is viewed and will in turn affect their behaviour. Lastly, the frame may affect the expectations that people have about each other’s behaviour and will in turn affect their own behaviour. While these functions are framed differently, regardless of the input ‘x’, the outcome is analytically equivalent. Therefore, if a rational decision maker were to choose between these two functions, the likelihood of each function being chosen should be the same.

1. The sunk cost dilemma, when attempted to be resolved, requires an evaluation of whether further investment would just be throwing good money after bad.
2. In the following examples, you can clearly see how sunk costs affect decision-making.
3. They already did their analyses and determined that the future benefit they will receive from the factory will outweigh the cost of construction.
4. Unsurprisingly, recognizing that a feature or product is no longer achieving its objectives after investing considerable time, energy, and resources can be challenging.

The former framing type is positive and the latter is negative.

The $50 you spent would be a sunk cost but would not factor into whether or not you buy theater tickets in the future. In general, businesses pay more attention to fixed and sunk costs than people, as both types of costs impact profits. The sunk cost fallacy is a cognitive bias that makes you feel as if you should continue pouring money, time, or effort into a situation since you’ve already “sunk” so much into it already. This perceived sunk cost makes it difficult to walk away from the situation since you don’t want to see your resources wasted. Sunk costs are important because may act as distractors in decision-making.

Sunk cost is also known as past cost, embedded cost, prior year cost, stranded cost, sunk capital, or retrospective cost. In this example, the architecture fees are an example of a sunk cost. It contacts an architect to design a new space who drafts some preliminary drawings for a fee. Then, an economy slowdown occurs, and the company is now unsure whether it should continue with the new warehouse.

But if he chooses to overlook the sunk costs, he falls into the sunk cost trap or the sunk cost fallacy. This happens when he makes an irrational decision, one made without considering the money he’s already spent. If, for example, XYZ Clothing is considering shutting down a production facility, any of the sunk costs that have end dates should be included in the decision. To make the decision to close the facility, XYZ Clothing considers the revenue that would be lost if production ends as well as the costs that are also eliminated. If the factory lease ends in six months, the lease cost is no longer a sunk cost and should be included as an expense that can also be eliminated. If the total costs are more than revenue, the facility should be closed.

What Factors Lead to the Sunk Cost Fallacy in Decision-Making?

When individuals or groups invest time, money, effort, or even personal emotions into something, they may become emotionally attached to the idea of recouping those investments. This emotional attachment can lead to several detrimental behavioral patterns. Businesses with the highest sunk costs tend be those with the greatest barriers to entry and biggest startup costs.

How Understanding Sunk Costs Can Help Your Everyday Decision Making Processes

The contractor does a walk-through with the owner, discusses the project requirements, and quotes a total construction price of $100,000 to complete the job. Both parties agree, and the homeowner puts down 25%, or $25,000. The most common type of framing effect was theorised in Kahneman & Tversky, 1979 in the form of valence framing effects.[39] This form of framing signifies types of framing. The first type can be considered positive where the ‘sure thing’ option highlights the positivity whereas if it is negative, the ‘sure thing’ option highlights the negativity, while both being analytically identical. For example, saving 200 people from a sinking ship of 600 is equivalent to letting 400 people drown.

On a psychological level though, you might believe if you don’t go you won’t get your money’s worth. But if you go and don’t like it, you’ve not only wasted the cost of the ticket but a few hours of your time. You’ve compounded the financial loss with an opportunity loss.In a strict economic sense, a rational person ignores sunk costs and only considers variable costs when making a decision. To do otherwise would prevent one from making a decision purely on its merits. However, this approach is in conflict with the irrational human tendency to avert loss under any circumstances. In business speak, a sunk cost is a payment or investment that has already been made.

A real-world historical example of the sunk cost dilemma can be found in the construction of the Sydney Opera House in Australia. For example, if you decide halfway through installing new hardwood flooring in your house that you hate the way it looks, you have a sunk cost. The Sunk Cost Dilemma is a formal economic term that describes the emotional difficulty of deciding whether to proceed with or abandon a project when time and money have already been spent, but the desired results have not been achieved. According to the National Institutes of Health (NIH), this leads to irrational, emotion-based decision making, causing you to spend additional resources on a dead end instead of walking away from the situation that’s no longer serving you. The framing effect which underlies the sunk cost effect builds upon the concept of extensionality where the outcome is the same regardless of how the information is framed. This is in contradiction to the concept of intentionality, which is concerned with whether the presentation of information changes the situation in question.

Admitting that resources were wasted can be emotionally difficult. Economists suggest that, in theory, sunk costs are not relevant to future decision-making. In practice, however, sunk costs can and do significantly influence decisions about the future. This is largely because it’s psychologically challenging to let go of previously invested time, effort, or financial resources even if the outcome of those investments fails to meet expectations. When considering opportunity costs, it is critical to disregard sunk costs.

However, it is important to realize that not all fixed costs are considered sunk costs. However, sunk costs aren’t just useful for large companies deciding whether to enter new markets or close down factories. This principle can be applied in everyday life, and understanding it may impact how you make decisions. The sunk cost dilemma is also commonly discussed when considering investments, primarily in volatile investments like equity markets. Investors that have limited capital must make decisions on whether to hold or sell securities and must make the decision independent of historical emotions.

Sunk cost fallacy can also sneak up on you by inflating your sense of confidence in a situation. It can be really challenging to walk away forms and instructions from a situation where you’ve already spent any amount of time, money, or energy. What often happens is that you try to rationalize the situation by saying that, since the spent cost can’t be recovered, you might as well stay the course and/or allocate additional resources to try to make things better.
