The effects generated by events on destination dynamics and topology

This study investigates the effects generated by a mega-event (the World Expo 2015) on a destination (Milan), using network analytic methods. The horizontal visibility graph was used to transform the time series into a network. Two hypotheses are tested: first, the ability of the Milan Expo to generate a turning point; second, the ability of this event to increase the system’s stability. The findings are based on a longitudinal analysis (2004–2017) of three widely used metrics: occupancy, average daily rate, and revenue per available room. The empirical pieces of evidence confirm both hypotheses. The Milan Expo has generated a positive turning point increasing the system stability. In the conclusion section, some theoretical and practical advancements are proposed, along with the implications for future research, and the main study limitations.
