Jonathan Gruber continues MIT's 14.41 Public Finance and Public Policy course with a lecture on Medicare and redistribution through health policy. He examines how Medicare is structured and financed, who bears its costs and who receives its benefits, and how the program redistributes resources across income groups and generations. The lecture builds on prior sessions covering health care economics, situating Medicare within broader debates about efficiency and equity in public insurance programs. Gruber works through the mechanics of the program using standard public finance tools, walking through cost projections, funding sources like payroll taxes, and the tradeoffs policymakers face when expanding or restricting coverage. The seventy-seven minute session is part of MIT's Fall 2024 offering of 14.41, delivered in the standard lecture-hall format with slides and discussion.
