Which is found in a mixed economy but not in a free market system?

In a mixed economy, government intervention plays a significant role alongside private enterprise, allowing for regulations and policies that address social welfare, environmental protection, and economic stability. This contrasts with a free market system, where economic decisions are driven entirely by supply and demand with minimal government involvement. Consequently, aspects like public goods provision, social safety nets, and regulatory frameworks are characteristic of mixed economies but absent in pure free market systems.
