Explanation:

It is difficult to define a mixed-market economy, but in essence, almost all economies in the world are of this type now. A mixed-market economy is a system in which there is a dual interaction between a planned economy, where the government controls all aspects of production, and a free-market economy, where there is no governmental control at all. Also known as a dual economy, the mixed-market system is one where there is a balance between the roles played by the private and public sectors, and the govnerments will intervene the processes through regulations and policies, only when the situation merits it.
