In a pure market economy who determines which goods and services are produced and in what quantities?

In a pure market economy, the determination of which goods and services are produced and in what quantities is driven by the forces of supply and demand. Consumers express their preferences through their purchasing choices, while producers respond to these signals by allocating resources to meet demand. Prices act as indicators, guiding producers on what to create and in what amounts, resulting in an equilibrium where supply meets demand. This decentralized decision-making process allows for flexibility and innovation in the marketplace.
