This model is most common in public as well as private Prediction Markets. Under this model buyers bid prices up and sellers bid prices down until a consensus is reached. If no consensus is reached, no transaction will take place. If this situation persists, there is low activity in the market and it becomes illiquid. This model can be implemented with or without an automatic market maker.

Food People Power

For many years, people living in West Oakland had accepted eating unhealthy food as a way of life. That is, until a small group of people decided to change their community through Mandela MarketPlace, a non-profit that partners with local residents and rural, minority farmers to bring fresh agricultural produce to their local corner stores. Mandela MarketPlace now represents the difference that youth can make by challenging prevailing paradigms - you CAN select what you put in your body.
