Managerial economics applies economic theory and quantitative methods to business administration problems. It bridges economic theory and business practice for facilitating managerial decision-making and planning. Managerial economics uses concepts from microeconomics and integrates economic theory with management principles. It helps managers make optimal decisions regarding production, pricing, inputs, profits, investments, and forecasting through tools like demand analysis, cost-benefit analysis, and quantitative modeling. Managerial economics draws from disciplines like accounting, finance, statistics, mathematics, and operations research.
