“…They observe that the price is higher in periods with lower price sensitivities, and that a lower price is set when the available inventory for the whole horizon is greater. Based on the assumption often considered in the RM hotel sector, according to which 'customers who book later are willing to pay higher rates', in an empirical analysis, Lee et al (2011) prove that rates, particularly rates for the retail segment, do not increase as the day of arrival approaches. This result is different to the one found in the airline sector; where, for example, the leisure segment usually books earlier compared with the business segment, and the first segment is defined as the most sensitive, therefore, the typical price path is one where price increases along the booking horizon (Narangajavana et al, 2014;Talluri and van Ryzin, 2005).…”
