Explain how public disclosure is used as a tool to prevent market failures.

The correct answer is Provide info that people want.

Explanation:

Externalities are caused when the production or consumption of a good or service has a cascading effect that is not purely reflected in its price and therefore there is no appropriate compensation to be paid for it. If the price does not include the true costs of the good or service there will be a market failure. Importantly, externalities can be positive or negative. To prevent refusals, governments must add certain taxes to assets to cover their social cost.
