Privatization

Privatization is the incidence or process of transferring ownership of business from the public sector (government) to the private sector (business). In a broader sense, privatization refers to transfer of any government function to the private sector including governmental functions like revenue collection and law enforcement.
The term "Privatization" also has been used to describe two unrelated transactions. The first is a buyout, by the majority owner, of all shares of a public corporation or holding company's stock, privatizing a publicly traded stock. The second is a demutualization of a mutual organization or cooperative to form a joint stock company.
In Roman Republic, private individuals and companies supplied nearly everything, including tax collection, supply the army, religious sacrifices and construction. However, Roman Empire created state-owned enterprises. For example, much of the grain was eventually produced on estates owned by the Emperor. Some scholars suggest that the cost of bureaucracy was one of the reasons for the fall of Roman Empire.
