Study Notes
The role of government in microeconomics involves interventions to influence market outcomes, such as earning revenue, supporting firms and households, influencing production and consumption, correcting market failures, and promoting equity. Price controls, like price ceilings and floors, are tools used to prevent prices from reaching equilibrium, resulting in market disequilibrium and affecting stakeholders differently.
