Can online auctions beat online catalogs?

Yaniv Vakrat, Abraham Seidmann
1999 International Conference on Information Systems  
In this paper, we report the results of an extensive study comparing the price paid in 473 online auctions with the prevailing prices of identical goods sold through online catalogs.  ...  Our results reveal a striking phenomenon: auction winners enjoy an average discount of 25% relative to the catalog prices for identical items sold at the same site.  ...  ANALYZING ONLINE AUCTIONS In this section, we construct a comparative model between online auctions and online catalogs.  ...

Consumer Surplus in Online Auctions

Ravi Bapna, Wolfgang Jank, Galit Shmueli
2005 Social Science Research Network  
Our analysis, based on a sample of 5187 eBay auctions, indicates that the median surplus level per auction on eBay auctions is $3.53, which roughly translates to $1.47 billion in accrued consumer surplus  ...  Using an ongoing novel field experiment, we collect and examine a unique dataset to empirically quantify and understand determinants of consumer surplus in eBay auctions.  ...  These comparative studies are presented as a series of box plots and QQ plots below.  ...
