演讲内容简介:

People commit the sunk cost fallacy when their decisions are influenced by costs that have already been incurred and cannot be reversed. The implication of the sunk cost fallacy is that the price discount may reduce consumption. Recently the gambling- or lottery-type price discount is drawing more and more attention to its impact on consumer buying decision. However, it is unclear how this probabilistic price discount affects consumption when the sunk cost fallacy is implicated, and how it differs from the sure price discount with equal expected monetary value. In a large-scale randomized field experiment conducted in a museum, we compare the impact of these two price discount schemes on consumption behavior – the length of time customers stayed in the museum. We found that the length of stay is more likely to be reduced by the probabilistic price discount than by the sure price discount. In another treatment condition, we offered the customer a choice between the probabilistic price discount and the sure price discount. We found that customers in the condition with choice stayed longer than the other two conditions without choice. Overall, the results are consistent with a diminishing sensitivity to sunk cost and a reference-dependent sunk cost effect.
