As for the contextual variables, the positive coefficient associated
to the booking time (0.0014, p < 0.10) indicates a slightly
decreasing trend of prices when approaching the check-in date
providing evidence of last minute strategies. While there is no
evidence of a weekend price-shift, the general level of demand,
measured by the average occupancy rate in the center of Milan for
the collected dates, exerts a significant pressure on the price level: a
one percent increase in the average occupancy would lead, on
average, to a 0.44% price increase
