Externalities in Theory - Lecture 2

Explore the theoretical foundations of externalities in this 77-minute lecture from MIT's Public Finance and Public Policy course. Examine how externalities impact three critical areas of public economics: public goods provision, social insurance systems, and taxation policy. Learn from Professor Jonathan Gruber as he breaks down complex economic concepts and demonstrates how external effects influence market outcomes and government intervention strategies. Gain insights into the theoretical framework that underlies many public policy decisions and understand the economic rationale behind government involvement in markets where externalities are present.
