The definition above already suggests that they can be either positive or negative. This can be seen on the graph. The difference in value of each unit between the optimum output and the market output is shown by the shaded triangle ( welfare loss ). Through the graph, it will be more clear why the negative externality causes the surplus in the market. Therefore there is under-consumption of the positive externality. The output (Q2) is social efficient: because here Social marginal cost (SMC) = Social marginal benefit (SMB) Advantages of subsidies. For example, the industry supplying smallpox vaccinations is assumed to be selling in a competitive market. However, this is socially inefficient because at Q1, social marginal cost < social marginal benefit. Additionally, there is another (and maybe less familiar) distinction which should be made here: Both positive and negative externalities can arise on the production or on the consumption side.
