We analyse 20,268 shopbot consumers who select various books from 33 retailers over 69 days. Although each retailer offers a homogeneous product, we find that brand is an important determinant of consumer choice. The three most heavily branded retailers hold a $1.72 price advantage over more generic retailers in head-to-head price comparisons. In particular, we find that consumers use brand as a proxy for retailer credibility in non-contractible aspects of the product and service bundle, such as shipping reliability.", pages = "541-558(18)", url = "http://www.ingentaconnect.com/content/bpl/joie/2001/00000049/00000004/art00009" doi = "doi:10.1111/1467-6451.00162" }
