1. Regulators should assert influence over the derivatives market, like they do with stocks, and require derivatives to be traded on an open exchange where buyers and sellers disclose prices and fees.
2. Nothing shoul be done to change how derivatives are bought and sold. If buyers and sellers don't like the lack of dealer transparency then they can choose not to trade derivatives.
3. The derivatives market should be modified only slightly to allow other players (e.g, banks) to provide and derivatives. If they then choose to disclose prives and fees, that is their choice, just as it is the choice of others to buy derivatives.
4. Invent other alternatives and explain.
