This master's thesis examines the effect of signaling on tourism trends. The author creates a model to analyze how the signaling effect of tourist attractions influences the number of visitors. Specifically, the model looks at how declaring a site as a World Heritage Site acts as a signal that impacts visitor numbers. The analysis finds some sites saw an increase in the signaling effect and visitors after being named a World Heritage Site, while others saw a decrease. Sites that saw an increase were likely less popular previously, while those with a decrease were likely more popular before the designation.
