We are exploring the design and creation of information markets with a goal of bringing an electronic, distributed market to a community or an organization to enhance knowledge sharing, innovation creation, and productivity. We apply innovative market mechanisms to construct incentives while still encouraging pro-social behaviors. A key advantage of this study will be a direct appeal to information economic theories and market principles on information markets design. A web-based software platform called Barter is developed and deployed at several sites. We will measure the results and test the effectiveness of an information market in addressing organizational challenges.
