<u>Mixed Economy:</u>
The mixed economy in economics cohabits with the government's intervention in the market systems of allocating resources, trade, and commerce.
When a government gets involved to undermine free markets through the establishment of state-owned companies (such as public healthcare or education), legislation, incentives, tariffs, and taxation policies, it may create a mixed economy.
It is structured among true capitalism and true socialism, with a certain number of free-market components and social democratic elements. It is the combination of the aspects of capitalism and socialism.
Mixed economies generally preserve private control and ownership over most production processes but often regulated by the state. These type of economies are socializing industries which are considered essential.
Even if some economists question the economic consequences of different mixed modes of economics, they are all common in historical and contemporary economies.
