Abstract: A facility for automatically determining a recommended price for an entertainment event ticket is described. The facility determines a first group of attributes of the entertainment event ticket. For each of a second group of attributes selected from the determined first group of attributes, the facility applies to the attribute a lift factor determined for the attribute to obtain a quantitative measure of the effect of the attribute. The facility then combines the obtained quantitative measures of attribute effects to obtain a recommended price for the entertainment event ticket.
