The paper acknowledges limitations in the generalizability of Prospect Theory (PT) to real-world scenarios, particularly in tourism where utilities are difficult to quantify. This limits the practical application of the findings.
Reliance on Stated Preferences
The reliance on self-reported data (stated preferences) in many of the reviewed studies introduces potential biases and may not accurately reflect actual behavior. This raises concerns about the validity of some conclusions.
The paper identifies confusion between related concepts like loss aversion and risk aversion, as well as the certainty/possibility effect. This highlights a need for greater clarity and precision in applying PT principles.
Limited research on PT applications in certain tourism sub-sectors (e.g., recreation, food and beverage) and on the supply-side limits the breadth of understanding of decision-making across the tourism industry.
Static Decision-Making Focus
The focus on static decision-making processes, rather than dynamic ones, fails to capture the evolving nature of tourist preferences and decisions over time.
