What is the distinction between yield and atom economy?

Yield refers to the amount of product obtained from a chemical reaction compared to the theoretical maximum possible, often expressed as a percentage. Atom economy, on the other hand, measures the efficiency of a reaction in terms of how well atoms from reactants are incorporated into the desired product, calculated by comparing the molar mass of the desired product to the total molar mass of all reactants. While yield focuses on the quantity of product produced, atom economy emphasizes the sustainability and efficiency of the reaction in utilizing resources effectively.
