What do the three kinds of economic system have in common?

The three primary types of economic systems—traditional, command, and market—share the fundamental objective of allocating resources to meet the needs and wants of society. Each system involves decision-making regarding production, distribution, and consumption, albeit through different mechanisms: tradition and customs in traditional systems, central planning in command systems, and supply and demand in market systems. Moreover, all three systems aim to address the basic economic questions of what to produce, how to produce it, and for whom to produce.
