There are two types of systems in organizations: closed systems and open systems. An open system interacts with its environment through giving and receiving information. Closed systems are closed off from the outside environment, and all interaction and knowledge is transmitted within the closed system only.
DEFINITION of 'Closed Economy'. An economy in which no activity is conducted with outside economies. A closed economy is self-sufficient, meaning that no imports are brought in and no exports are sent out. The goal is to provide consumers with everything that they need from within the economy's borders. A closed economy is the opposite of an open economy, in which a country will conduct trade with outside regions.
