Behavior-based pricing under imperfectly informed consumers
Esteves, Rosa Branca; Cerqueira, SofiaThis paper is a first look at the dynamic efects of BBPD in a horizontally diferentiation product market, where rms need to invest in advertising to generate awareness. When a rm is able to recognize customers with diferent purchasing histories, it may send them targeted advertisements with diferent prices. We show that in comparison to no discrimination, rms reduce their advertising eforts, charge higher rst p...

When a firm is able to recognize customers with different purchasing histories, it may send them targeted advertisements with different prices. In comparison to no discrimination, it is shown that firms reduce their advertising efforts, char...
