prices guide the decisions of buyers and sellers and these decisions lead to an efficient allocation of resources
For private goods allocated in markets, the government guides the decisions of buyers and sellers and these decisions lead to an efficient allocation of resources prices guide the decisions of buyers and sellers and these decisions lead to an efficient allocation of resources prices guide the decisions of buyers and sellers and these decisions lead to an inefficient allocation of resources the government guides the decisions of buyers and sellers and these decisions lead to an inefficient allocation of resources
