What is the type of mechanism that answers the basic economic questions through a decentralized decision-making process?

The type of mechanism that addresses basic economic questions through a decentralized decision-making process is known as a market economy. In this system, individual consumers and producers make decisions based on their preferences and resource availability, leading to the allocation of goods and services through supply and demand dynamics. Prices serve as signals to guide these decisions, allowing for efficient resource distribution without central planning.
