Which economies are mixed?
There is not a consensus on which economies are capitalist, socialist, or mixed. It may be argued that the historical tendency of power holders in all times and places to limit the activities of market actors combined with the natural impossibility of monitoring and constraining all market actors has resulted in the fact that, as we understand a "mixed economy" being a combination of governmental enterprise and free-enterprise, nearly every economy to develop in human history meets this definition.
