Mazón, CristinaPereira, Pedro2006-11-092006-11-092001-122340-5031https://hdl.handle.net/10016/264This paper explains three things in a unified way. First, how e-commerce can generate price equilibria, where physical shops either compete with virtual shops for consumers with Internet access, or alternatively, sell only to consumers with no Internet access. Second, how these price equilibria might involve price dispersion on-line. Third, why prices may be higher on-line. For this purpose we develop a model where e-commerce: reduces consumers search costs, involves trade-offs for consumers, and reduces retailing costs.1001011 bytesapplication/pdfengAtribución-NoComercial-SinDerivadas 3.0 Españaworking paperEconomíaopen accesswe016722
