“…2 Furthermore, this study also documents a noticeable source of online price dispersion within each single airline's website and thus fills a gap in the literature, which has produced scant empirical evidence of online intra-firm price dispersion and has mainly focussed on the sources of online inter-firm price dispersion (see, inter alia, Baylis and Perloff, 2002;Baye et al, 2004;Brynjolfsson and Smith, 2000;Clay et al, 2001;Clemons et al, 2002;Smith and Brynjolfsson, 2001; and the surveys by Baye et al, 2006;Ellison and Ellison, 2005;Stole, 2007). A notable exception is the work by Cabolis et al (2007) showing evidence of international price discrimination for the economics textbook sold by Amazon on its US and British websites, with American prices being substantially more expensive. 3 To shed further light onto the properties and the motivations underlying the previously described pricing scenarios, the present paper draws from and aims to contribute to two generally distinct strands of literature, one studying price dispersion in e-commerce setups, the other in airline markets.…”
