But for some goods, additional consumers do not add to cost. In this case, they are equivalent to the private marginal benefits and costs. Since, on our assumptions, total profit from fish production from the lake is the net social benefit, maximisation of profit leads to efficient labour input.
But the fact that their products may have positive externalities means that the fees producers charge for the use of their products do not reflect the full benefits their products deliver.
