TY - JOUR AB - Purpose– The purpose of this paper is to explore the use of information aggregation markets (IAMs) for community‐based idea management and to present IDeM, a novel Internet‐based software tool that can be used for generating and evaluating new ideas utilizing the concept of IAMs.Design/methodology/approach– Starting with a review of existing methods for collective intelligence, IAMs are identified as a prominent method for collective intelligence. Specific requirements for exploring IAMs for idea management are derived. Based on these requirements, a software tool for implementing IAMs in the context of idea management is developed (IDeM). IDeM has been evaluated and evaluation results are used to identify IDeM's benefits and limitations. A review of related work points out the innovative characteristics of IDeM.Findings– Evaluation results indicate that IAMs is an efficient method for idea generation and evaluation. Moreover IDeM is perceived both as easy to use and efficient in supporting idea generation and evaluation.Practical implications– IDeM can be used by commercial or other organizations for supporting generation and evaluation of new ideas.Originality/value– IDeM's innovative aspects are: in addition to trading, it allows users involvement by means of new idea submission, rating of ideas and commenting on ideas; it confronts the uncertainty of new idea related events by offering an expert based valuation mechanism.; and it extends the typical output of IAM tools – which is price of idea‐stocks – by calculating the volume weighted average price.
