Marginal Social Benefit (MSB) vs. Marginal Private Benefit (MPB)
The Marginal Private Benefit (MPB) is the direct benefit to the consumer or producer from one additional unit of a good or service. The Marginal Social Benefit (MSB) includes the MPB plus the marginal external benefit (MEB) that accrues to third parties. In the case of a positive externality, MSB is greater than MPB (MSB = MPB + MEB). The socially optimal quantity is where MSB equals the marginal social cost (MSC), whereas the market equilibrium occurs where MPB equals the marginal private cost (MPC).
