Experimental economics is a branch of economics that uses controlled experiments to test economic theories and explore various aspects of human behavior in economic decision-making. It allows researchers to observe and analyze how individuals make choices in controlled settings, often using real incentives, and investigate the validity of economic theories in practice. Experimental economics has been instrumental in addressing questions related to market behavior, game theory, finance, and public policy, among other areas. By conducting experiments, researchers can gain insights into economic behavior that complement traditional theoretical and empirical methods.
