Respondents in one group earned an “asset” (a lottery ticket that paid $10 with a 10% chance) by performing well on a laborious task . Respondents in a second group were not required to complete any task but were simply asked to choose between the two assets. In one scenario, people were asked to imagine that they were accidentally scheduled to take two trips — one to Montreal, and one to Cancun — during the same weekend, forcing them to choose one.
Participants were then asked which of the ski trips they would go on if it was too late to return either ticket. Some investors actively seek out risk as they believe those types of investments offer the greatest returns. On the other hand, other investors still stick cash under the mattress and would rather forfeit any potential growth out of liquidity protection.

Lastly, the frame may affect the expectations that people have about each other’s behaviour and will in turn affect their own behaviour. 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.
Since the Sunk Cost fallacy is thought to be caused by our desire to avoid negative emotions, we should try to take our emotions out of the equation when making a decision. Instead, we may want to use technologies to help us make decisions when it comes to scenarios where we might be influenced by the sunk cost fallacy. The sunk cost fallacy not only has an impact on small day-to-day decisions like attending a concert. It also has been proven to impact the decisions that governments and companies make. Many people have strong misgivings about “wasting” resources that may contribute to the sunk cost effect.

One way to stay disciplined is to draft a trading plan ahead of time outlining what you’re trying to accomplish and how you are going to accomplish it. Key elements of your trade plan should include your investing time horizon, entry and exit strategies, position size and trade performance review.
What is sunk cost?
Sunk costs are expenses incurred to date in a project that are already spent and as a result cannot be recovered.
A https://online-accounting.net/ refers to money that has already been spent and cannot be recovered. A manufacturing firm, for example, may have a number of sunk costs, such as the cost of machinery, equipment, and the lease expense on the factory. Sunk costs are excluded from a sell-or-process-further decision, which is a concept that applies to products that can be sold as they are or can be processed further. More examples The investment in consolidating a market involves substantial sunk costs and should not be undertaken lightly. Statistical analysis of the response data suggested we select eight of these 18, leaving us with our scale, the “SCE-8”. The resources each of those scenarios focuses on is shown in the exhibit Testing Sunk Costs. Our analysis identified which scenarios gave responses that best described the most variation in the data.

I exploit a natural experiment in which residential water customers switched exogenously from bimonthly to monthly billing. Customers increase consumption by 3.5–5% in response to more frequent information. This result is reconciled in models of price and quantity uncertainty, where increases in billing frequency reduce the distortion in consumer perceptions. Using treatment effects as sufficient statistics, I calculate consumer welfare gains equivalent to 0.5–1% of annual water expenditures. Heterogeneous treatment effects suggest increases in outdoor water use.
- In economics, a “sunk cost” is an expense that’s already been incurred and can’t be recovered.
- On the other hand, other investors still stick cash under the mattress and would rather forfeit any potential growth out of liquidity protection.
- As long as those wages are not recoverable, that salary represents an expense that has been incurred and can not be captured back by the company.
- As one accepts where they went wrong, they won’t repeat the mistake again and hence, make a better decision in the future.
- To this end, we employed an operant procedure that allowed pigeons and humans to continue with or to abandon a course of action that had started out with good prospects but turned sour.
We are likely to continue watching a movie if we’ve invested both time and money into it even though those investments cannot be recovered by continuing to watch the movie. Age seems to have an impact on how much time we are willing to continue watching the movie, with younger people being more susceptible to the sunk cost fallacy.
A ticket buyer who purchases a ticket in advance to an event they eventually turn out not to enjoy makes a semi-public commitment to watching it. 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 of the alternative use of time. Daniel Kahneman, an Israeli psychologist known for his work in behavioral economics and studies of rationality in economics. The bygones principle can also be formalised as the notion of “separability”. In the language of decision trees, it requires the agent’s choice at a particular choice node to be independent of unreachable parts of the tree.
Each scenario provides a realistic everyday situation that anyone should be able to easily imagine themselves in. In most instances a variety of costs are sunk because people’s resources tend to be highly interconnected. For these reasons it seems undesirable and futile to try to always refer to only one type of resource per scenario or to only offer scenarios that feature one resource. Rather, it is important to include scenarios that emphasize different mixes of resources. Another way to describe this would be if a project has spent all of its 1,000k to develop a product and needs only another 100 to release to market. It seems a simple enough approach that for ‘just another 100’ we can get our product out the door but therein lies the bias if considering sunk costs.
