Considering that market economies do not always function ideally, there is market regulation involving industries that operate as monopolies or oligopolies. Industries engaged in activities with which they can operate under monopoly conditions determine the price increase and they limit the produced quantities of these goods. In such conditions, the intervention of the state is needed in order to protect its citizens from excessive price increases. Therefore, we can conclude that market regulation actually represents a group of certain measures that the state can adopt in order to control the decisions of individual branches of activities that operate in its territory and with such measures protect not only citizens, but the entire public, nongovernmental and non-profit sector and companies. The measures that the state can adopt include: introducing a minimum price for certain products, purchasing almost all products to maintain their price, limiting production, encouraging producers with various subsidies, as well as passing regulations that determine the quotas of certain products. Through their activities, state regulatory agencies can be divided into those that limit the market power of regulated companies, as well as those whose main goal is the protection and safety of workers and companies. The most important thing in everything is to have timely and as accurate information as possible so that the entire economy operates in the right direction. Data on the revenues that the state will be able to dispose of, is important so that state can distribute expenditures as best as possible with the aim of creating a surplus, that is, a state in which revenues are greater than expenditures. Ultimately, the surplus implies prosperity and better employment, which is the basis of higher incomes and improved quality of all citizens.
