The curve AB=1_day measures the instantaneous impact of Covid-19; the more the curve falls the fewer hotels offer rooms in the short term. The indication is: "hotels looking for customers for one night between today, tomorrow and the day after tomorrow are the X% of the total sample". The curves for different advance bookings provide information on future expectations and how they change: for example, if the curve AB=140_days is much higher than the curve AB=56 days it means that the great majority of hotels is confident that activity will resume after two months and before five months.
The comparison of HAI week after week allows us to have a dynamic view of how expectations change in light of the evolution of the pandemic and of the rules regulating the lockdown. The CAST team working on the index is also working on the structure of prices posted by hotels in Milan and Venice at different advance bookings. Stay tuned on the CAST website to be updated on the future developments of the index.
