A Government Corporation is a type of government agency that operates like a private business but is owned and funded by the government. These corporations are created to provide specific services or products that may not be profitable for private companies. Examples include the United States Postal Service and Amtrak, which serve public needs while aiming to be financially self-sustaining. Government corporations are established by legislation and are accountable to the public and government oversight. They often have more flexibility in operations compared to traditional government agencies, allowing them to respond more quickly to market demands while still fulfilling their public missions.
