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?
I believe it is a good idea to encourage employees to trade in these markets. In this case Google has a very effective tool for informing managers. These market questions can be applied to advise small projects or create scenarios to inform future investment. Additionally, Google could sell the outcomes of market scenarios to interested parties.
I also believe insiders and uninformed people should participate in the trading process. Both these extremes balance the information being shared amongst market participants. Additionally, no market participant has perfect information which is again a balancing control in the process. Insiders can potentially shape the market in profound ways, but they’re influence can be diminished by the number of users. The same factor applies to uninformed; the number of participants will drive the impact these voices have on outcomes.
