  abstract =	 {In this paper, we propose a market model and
                  learning algorithms for buying and selling agents in
                  electronic marketplaces. We take into account the
                  fact that multiple selling agents may offer the same
                  good with different qualities, and that selling
                  agents may alter the quality of their goods. We also
                  consider the possible existence of dishonest selling
                  agents in the market. In our approach, buying agents
                  learn to maximize their expected value of goods
                  using reinforcement learning. In addition, they
                  model and exploit the reputation of selling agents
                  to avoid interaction with the disreputable ones, and
                  therefore to reduce the risk of purchasing low value
                  goods. Our selling agents learn to maximize their
                  expected profits by using reinforcement learning to
                  adjust product prices, and also by altering product
                  quality to provide more customized value to their
                  goods. This paper focuses on presenting results from
                  experiments investigating the behaviours of buying
                  and selling agents in large-sized electronic
                  marketplaces. Our results confirm that buying and
                  selling agents following the proposed algorithms
                  obtain greater satisfaction than buying and selling
                  agents who only use reinforcement learning, with the
                  buying agents not modelling sellers reputation and
                  the selling agents not adjusting product quality.},
