Текст:

1. There are many forms of economic order, ranging from the mixed private enterprise system to partially or completely controlled economies. Regardless of their form, economic system is the system that a society uses for allocation and distribution of scarce resources. Private enterprise means that decisions about what and how much to produce are left to the discretion of owners and managers. In controlled economies such decisions are the responsibility of some governmental agency. There is no economy today that is completely free of governmental influence. There are many beneficial services and protections available from government. It performs certain valuable functions in the life of organizations of all types.
2. Among the functions of the economic order the most important one is to provide some resources. In a private enterprise this function is basically performed by the price mechanism. Demand and supply of goods and services interact to set their market price. In the case of regulated utilities, there are governmental agencies such as public service commissions that determine the rates. These rates are set at the level that will allow a fair return on investments made by the companies. This form of regulated monopoly is considered preferable to unchecked competition. This is true because of efficiency reasons. In taking actions in the area of employment, government is attempting to control the economy to help the business community operate at the level of production.
