What are Externalities?

Marginal Private Benefit (MPB): Additional benefit enjoyed by the individual/firm when producing/ consuming an additional unit of the good/service

Marginal External Benefit (MEB): Additional benefit enjoyed by third parties not involved in the economic transaction when producing/ consuming an additional unit of the good/service

Marginal External Cost (MEC): Additional cost borne by third parties not involved in the economic transaction when producing/ consuming an additional unit of the good/service
