Is it a good idea to encourage ALL employees to trade in these markets? Should insiders and/or highly uninformed people be allowed to trade? Do they help or hurt the market?
Yes, everyone should be encouraged because the idea is to get the masses knowledge to predict an outcome. The more people that contribute the more accurate the prediction. Insiders and highly uninformed people should be allowed to trade. The idea behind the prediction model is that masses knowledge is better then the smartest person in the mass. The one googler commented that she already knew the outcome of one of the predictions for one of her group’s project but that the outcome just confirmed her intuition. Having uninformed and highly informed people help the market because the more people that are in the market more likely the prediction is to be correct. Highly informed people are likely to move the market closer to the correct prediction. Uninformed people are either going to go along with their gut feeling or they are going to be convinced to go one way because the market is going that way. At google 13 people accounted for 48% of the trades so you see they may be the market movers and could move people to act in a certain way, much like the stock market. When one big bank sells a stock because they know something you don’t it generally drives the price down then everybody else starts selling. Prediction markets probably function about the same way.
