| Summary: | 碩士 === 國立雲林科技大學 === 會計系研究所 === 95 === Sunk cost is irrelevant in making decisions. However, recent research in psychology suggests that people will make decisions that is bias when they make decisions. The reason of bias results may be that unrelated information is considered. The subjects are the college student of the accounting department and information management department. Adopting a 2(related to the decision making vs. unrelated to the decision making)*2(sunk cost knowledge vs. no sunk cost knowledge)*2(financial incentives vs. no financial incentives) factorial design in which the former two variables are manipulated between subjects.
The result of research suggests that people tend to cause make bias decisions when they confront face the former fault that is no matter related to the decision-making condition or not. However, this result is opposed to the frame hypothesis advanced by Tversky and Kahneman. In addition, provision of sunk cost knowledge improves decision performance. The results of experiments show that financial incentives motivates subjects to exert more cognitive effort, but they do not significantly reduce decision errors. This finding is essentially consistent with existing behavioral accounting literature, especially Kennedy’s model. Sunk cost effect belongs to one kinds of data-related bias.
