Cost Effect

Human decision-making is often swayed by irrecoverable investments even though it should only be based on future – and not past – costs and benefits. Although this sunk cost effect is widely documented and can lead to devastating losses, the underlying psychological mechanisms are unclear. To tease apart possible explanations through a comparative approach, we assessed capuchin and rhesus monkeys’ susceptibility to sunk costs in a psychomotor task. Monkeys needed to track a moving target with a joystick-controlled cursor for variable durations. They could stop at any time, ending the trial without reward. To minimize the work required for a reward, monkeys should have always persisted for at least 1 second, but should have abandoned the trial if that did not yield a reward. Capuchin monkeys and especially rhesus macaques persisted to trial completion even when it was suboptimal, and were more likely to complete the trial the longer they had already tracked the target. These effects were less pronounced, although still present, when the change in expected tracking duration was signalled visually. These results show that sunk cost effects can arise in the absence of human-unique factors and may emerge, in part, because persisting can resolve uncertainty.

Cost Effect

Researchers and design practitioners advocate building physical models of ideas at early stages of the design process. Still, the cognitive effects of physical models remain largely unknown. Some studies show that physical models possess the potential to facilitate the generation of high quality ideas. Conversely, other studies demonstrate that physical models can lead to design fixation. A prior controlled study by the authors failed to detect fixation due to early stage physical models. Based upon these conflicting results, this study hypothesizes that the fixation observed in prior studies can be explained by the Sunk Cost Effect. The Sunk Cost Effect pertains to an individual's reluctance to choose a different path of action once he/she invests a significant cost (money, time, or effort). According to this theory, as designers spend more time, money or effort in building physical models, they tend to generate ideas with lower novelty and variety. The prior observational studies use complicated design problems with higher costs compared to the controlled study, possibly explaining the difference in results. This study also hypothesizes that physical models supplement designers' erroneous mental models. The authors investigate these hypotheses through a controlled, between-subject experiment with five conditions: Sketching Only, Metal Building (low time cost), Plastic Building (high time cost), Metal Constrained Sketching, and Plastic Constrained Sketching. In each condition, subjects construct their ideas using materials specified by the name of the condition. The constrained sketching conditions assist in determining if participants tend to limit their ideas to only ones that can be built with given materials even though they are instructed to write down all ideas. The results confirm that the sunk cost of building plays a vital role in the observed fixation; thus, physical models do not inherently cause fixation. Moreover, results also show that physical models supplement designers' erroneous mental models, leading to higher quality ideas. To minimize sunk costs very early in the design process, models should be built with materials requiring minimal time, cost, and effort for the designers.

Cost Effect

Rational decision makers aim to maximize their gains, but humans and other animals often fail to do so, exhibiting biases and distortions in their choice behavior. In a recent study of economic decisions, humans, mice, and rats have been reported to succumb to the sunk cost fallacy, making decisions based on irrecoverable past investments in detriment of expected future returns. We challenge this interpretation because it is subject to a statistical fallacy, a form of attrition bias, and the observed behavior can be explained without invoking a sunk cost-dependent mechanism. Using a computational model, we illustrate how a rational decision maker with a reward-maximizing decision strategy reproduces the reported behavioral pattern and propose an improved task design to dissociate sunk costs from fluctuations in decision valuation. Similar statistical confounds may be common in analyses of cognitive behaviors, highlighting the need to use causal statistical inference and generative models for interpretation.

Purpose: The objective of this paper was to analyze the influence of the sunk cost effect in the decision-making process of Accounting and Business Administration undergraduate students of the Federal University of Rio Grande do Norte. Methodology: The sample comprised 655 students, of which 347 were from the Accounting program and 308 from a Business Administration program. Data were collected through the application of structured questionnaires, based on the studies of Arkes and Blumer (1985), Rover, Wuerges, Tomazzia and Borba (2009) and Silva and Domingos (2010). After tabulation, the data were analyzed through descriptive statistics, as well as a Mann-Whitney U test to verify if there are differences between the answers of the Accounting and Business Administration students. Results: The main results suggest that the amount of sunk cost can influence the occurrence of the sunk cost effect, and this evidence is perceived through the mean values, considering that the reduction of the amount of sunk cost is inversely proportional to the average disposition of the respondents in continue investing in the course of action. In addition, to identify that the investigated students take the sunk costs into consideration in the decision-making process, it is verified that there is no statistically significant difference between the medians of the respondents with regard to the questions that allow identifying the susceptibility to the sunk cost effect in the context of business decision-making. Contributions of the Study: The study contributes to signal that the future professionals of Administration and Accounting are susceptible to the sunk cost effect, which can imply in a report of biased accounting information by future accountants, as well as biased decisions by future administrators. Furthermore, these results contrast previous evidence that suggests that agents from different areas of knowledge react differently to the presence of sunk costs.

Cost Effect

Escalation is a serious management problem, and sunk costs are believed to be a key factor in promoting escalation behavior. While many laboratory experiments have been conducted to examine the effect of sunk costs on escalation, there has been no effort to examine these studies as a group in order to determine the effect size associated with the so-called “sunk cost effect.” Using meta-analysis, we analyzed the results of 20 sunk cost experiments and found: (1) a large effect size associated with sunk costs, and (2) stronger effects in experiments involving information technology (IT) projects as opposed to non-IT projects. Implications of the results and future research directions are discussed.

Cost Effect

The sunk-cost fallacy—pursuing an inferior alternative merely because we have previously invested significant, but nonrecoverable, resources in it—represents a striking violation of rational decision making. Whereas theoretical accounts and empirical examinations of the sunk-cost effect have generally been based on the assumption that it is a purely intrapersonal phenomenon (i.e., solely driven by one’s own past investments), the present research demonstrates that it is also an interpersonal effect (i.e., people will alter their choices in response to other people’s past investments). Across eight experiments ( N = 6,076) covering diverse scenarios, I documented sunk-cost effects when the costs are borne by someone other than the decision maker. Moreover, the interpersonal sunk-cost effect is not moderated by social closeness or whether other people observe their sunk costs being “honored.” These findings uncover a previously undocumented bias, reveal that the sunk-cost effect is a much broader phenomenon than previously thought, and pose interesting challenges for existing accounts of this fascinating human tendency.

The One

The 2011 NFL collective bargaining agreement introduced significant changes to rookie compensation, including a rookie wage scale. We test if the new rules changed how sunk costs affect utilization for drafted rookies. Our regression discontinuity results show a robust sunk-cost fallacy that is similar in magnitude to the one documented under the previous agreement. Second-round selections play significantly less than their first-round counterparts, as measured by percentage of games started, total snaps played, and percentage of snaps played. However, the effect is not evident beyond the rookie season. Additional results show coaching success and coaching changes are important factors.
