Marginal Social Benefits/MSB

Marginal Social Benefits (MSB) is an economic concept that describes the additional benefit provided to society by producing one additional unit of a good. It includes both private benefits - those enjoyed directly by consumers, and public benefits - those enjoyed by the rest of society, such as the environment. The MSB measures the value of producing a good beyond its own monetary value, and is used to compare the benefits and costs of production to gauge its overall effect on society.
