We consider eBay (or Taobao) like E-commerce systems, where a large number of sellers and buyers transact online. To reflect the trustworthiness of sellers, a reputation system is maintained. In particular, the feedback-based reputation system [4] is the most widely deployed. Sellers of such systems are initialized with a low reputation and they must obtain a sufficiently large number of positive feedbacks from buyers to earn a reputable label. For example, eBay and Taobao use three-level feedbacks, i.e., (-1 (Negative), 0 (Neutral), 1 (Positive). Each seller is initialized with a reputation score of zero. A positive (or negative) rating increases (or decreases) the reputation score by one, while a neutral rating does not change the reputation score.<\/jats:p>","DOI":"10.1145\/3305218.3305221","type":"journal-article","created":{"date-parts":[[2019,1,17]],"date-time":"2019-01-17T17:15:15Z","timestamp":1547745315000},"page":"3-5","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["A Markov Decision Process Approach to Analyze Discount &amp; Reputation Trade-offs in E-commerce Systems"],"prefix":"10.1145","volume":"46","author":[{"given":"Hong","family":"Xie","sequence":"first","affiliation":[{"name":"The Chinese University of Hong Kong, Hong Kong , China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John C.S","family":"Lui","sequence":"additional","affiliation":[{"name":"The Chinese University of Hong Kong, Hong Kong, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2019,1,17]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.1240466"},{"volume-title":"John Wiley & Sons","year":"2014","author":"Puterman M.
