document: Analyzing seller practices in a Brazilian marketplace E-commerce is growing at an exponential rate . In the last decade , there has been an explosion of online commercial activity enabled by World Wide Web ( WWW ) . These days , many consumers are less attracted to online auctions , preferring to buy merchandise quickly using fixed-price negotiations . Sales at Amazon.com , the leader in online sales of fixed-price goods , rose 37 % in the first quarter of 2008 . At eBay , where auctions make up 58 % of the site 's sales , revenue rose 14 % . In Brazil , probably by cultural influence , online auctions are not been popular . This work presents a characterization and analysis of fixed-price online negotiations . Using actual data from a Brazilian marketplace , we analyze seller practices , considering seller profiles and strategies . We show that different sellers adopt strategies according to their interests , abilities and experience . Moreover , we confirm that choosing a selling strategy is not simple , since it is important to consider the seller 's characteristics to evaluate the applicability of a strategy . The work also provides a comparative analysis of some selling practices in Brazil with popular worldwide marketplaces .
