sunk cost Opportunity Cost, Rational Decision-Making & Behavioral Biases Definition

Experimenting with new recipes is a part of research and development. You spend $100 on materials for one potential new product, and nobody purchases the product. After a test run, the customer feedback is that the new product is not something you should sell. Understanding the underlying psychology of the sunk cost mindset can shed light on why it’s so difficult to let go.

  • The best way to avoid the sunk cost trap is to set investment goals.
  • The results reveal inadequate profitability, so the logical choice is to shut down the project.
  • For example, a company invests $100,000 in a pilot project to manufacture green widgets.
  • Using straight-line depreciation, the company should recognize $1,000 in depreciation expense per year.
  • A program manager is someone who is responsible for leading a number of interdependent projects to achieve strategic objectives.

At some point, the rent may become an expense you can’t recover through your shop’s profit (a sunk cost). But after spending so much money on repairs, you decide you’d rather fix the old car so that the money you spent previously wasn’t all for nothing. You believe that you “invested” a lot of money into the car, and you don’t want to “lose” it by getting a new one.

What is the real consideration is what the 100 means for the marginal benefits of the product. If that 100 is to quickly add another feature given there has been a number of competitors beating your product to launch, there are some real considerations whether to launch at all. By authorising the extra 100, the total investment exposure increases yet may not result in any greater success with the product. 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.

Research and Development Sunk Cost

In general, businesses pay more attention to fixed and sunk costs than people, as both types of costs impact profits. A sunk cost is always classified as a fixed cost, though some fixed costs are not classified as sunk costs. A fixed cost that is a sunk cost cannot be recovered, as is the case with customized equipment for which there is no resale market. A fixed cost that is not a sunk cost can be recovered, usually by selling it to a third party; for example, a tractor trailer that can be sold on the resale market is not a sunk cost. In rational decision-making, sunk costs should not play a role in our future actions because we can never get back the money, time, or energy we have invested—regardless of the outcome.

In economic decision making, sunk costs are treated as bygone and are not taken into consideration when deciding whether to continue an investment project. A sunk cost is a cost that has already occurred and cannot be recovered by any means. Sunk costs are independent of any event and should not be considered when making investment or project decisions. Only relevant costs (costs that relate to a specific decision and will change depending on that decision) should be considered when making such decisions. The sunk cost fallacy is the improper mindset a company or individual may have when working through a decision.

A fixed cost, however, is not a sunk cost, because it can be stopped, for example, in the sale or return of an asset. Once a variable cost is incurred and cannot be recovered, however, it becomes fixed in sunk terms. By definition, $1,000 worth of variable costs are sunk if they cannot be recovered; once incurred, the realized sunk costs become fixed.

What is a Sunk Cost?

The sunk cost dilemma may lead to irrational decision-making where individuals or organizations make choices that defy logic and reason. Instead of assessing the current situation objectively, they are influenced by past investments. An example of a sunk cost would be spending $5 million on building a factory that is projected to cost $10 million. The $5 million already spent—the sunk cost—should not be taken into account when deciding whether the factory should be completed. What ought to matter instead are expectations of future costs and future returns once the factory is operational.

Sunk costs are the expenses you already incurred and do not play a role in purchases you plan to or will make. A program manager is someone who is responsible for leading a number of interdependent projects to achieve strategic objectives. The Program Manager focuses on overall benefits realization and achieving organizational goals rather than managing short deadlines and individual deliverables.

The defining characteristic of sunk costs is that they cannot be recovered. It’s easy to imagine a scenario where fixed costs are not sunk; for example, equipment might be resold or returned at the purchase price. The reason economic analysis ignores sunk costs is that doing so helps to prevent decision makers from throwing good money after bad when they are stuck in an unprofitable project. It is often the case that heavy initial investment in a poor project results in a temptation to spend more money on the project in the hope of recovering the sunk cost or preventing embarrassment.

How Can You Overcome the Sunk Cost Dilemma?

Sunk costs are important to be mindful of because incorrectly including them in an analysis may lead to a less favorable decision being chosen. However, behavioural economics suggests that individuals may have an attachment to the past sunk costs – because they spent $100million on a new software system, they want to try and make it work. The sunk cost fallacy can be observed in various contexts, such as business, relationships, and day-to-day decisions.

What Is a Sunk Cost Trap?

To leave early is to make this lapse of judgment manifest to strangers, an appearance they might otherwise choose to avoid. As well, the person may not want to leave the event, because they have already paid, so they may feel that leaving would waste their expenditure. Alternatively, they may take a sense of pride in having recognized the opportunity cost meaning of depreciation of the alternative use of time. Another example is that market research shows that a movie may not be popular or appeal to a wider audience. The studio then decides to spend more money on advertising to raise awareness and avoid loss. The basic sunk cost meaning is that it has already been incurred and should not be a part of the decision-making process.

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. The sunk cost dilemma, when attempted to be resolved, requires an evaluation of whether further investment would just be throwing good money after bad. The purely rational economic person would consider only the variable costs, but most people irrationally factor the sunk costs into our decisions. Avoid the sunk cost fallacy by monitoring the outcomes of your financial decisions and stopping projects that no longer show benefit. Do not compound sunk costs by continuing to spend money on investments or financial decisions with a negative financial outcome.

The construction of the Sydney Opera House began in the 1950s with an initial budget of 7 million Australian pounds. However, as the project progressed, it encountered numerous design and engineering challenges that led to cost overruns and delays. Architect Jørn Utzon’s innovative design, while iconic today, posed significant technical difficulties and was much more complex to develop than initially anticipated.
