The difference is that instead of the market equilibrium quantity being too much, the market will generate too little of Q. Lets look at an example. To determine the optimal quantity of a public good, it is necessary to first determine the demand for it. At any output level, social costs are greater than private (market) costs. a marginal benefit curve. And this would be the optimal price from a societal point of view.
