Why do governments provide social insurance to protect citizens against economic risks?
In short: In this lecture from MIT's Principles of Microeconomics, Professor Jonathan Gruber examines the mechanics of social insurance. By exploring how these systems function as a form of social welfare, the session clarifies the complex tradeoffs involved in managing economic uncertainty and the role of asymmetric information.
Professor Jonathan Gruber defines social insurance as a mechanism designed to shield individuals from specific economic risks. The lecture situates this within the broader framework of social welfare, analyzing why such programs are necessary and how they are structured to address market failures.
The discussion centers on the inherent tradeoffs policymakers face when designing these systems. A key focus is the impact of asymmetric information, which complicates the provision of insurance and influences the design of public programs like social security.
