Understanding what are the factors that influence non-buyers of floral products to become buyers, and the fact...

Multi-sided platforms are increasingly common, which is no surprise given the winner-take-all dynamics in platform-based markets. That is, the platform with the biggest installed base of buyers and sellers can arguably sustain its competitive advantage because of positive indirect network effects. We reexamine this argument with an agent-based simulation model, where we allow for variety seekin...

In this paper, we propose a novel incentive mechanism for promoting honesty in electronic marketplaces that is based on trust modeling. In our mechanism, buyers model other buyers and select the most trustworthy ones as their neighbors to form a social network which can be used to ask advice about sellers. In addition, however, sellers model the reputation of buyers based on the social network....

In this article, we focus on the scenario in which the inventory is in short supply, i.e. an e-marketplace with limited inventory (EMLI). The challenges are in two-fold: (a) for sellers who aim to maximize their profit, they may intentionally conduct dis...

We develop a model to show that the intermediary would want to restrict sellers from charging buyers more for transactions it intermediates. With this restriction an intermediary can profitably raise demand for its services by eliminating any extra price buyers face for purc...
