microeconomics

Definition

Study of the economic behavior of individual units of an economy (such as a person, household, firm, or industry) and not of the aggregate economy (which is the domain of macroeconomics). Microeconomics is primarily concerned with the factors that affect individual economic choices, the effect of changes in these factors on the individual decision makers, how their choices are coordinated by markets, and how prices and demand are determined in individual markets. The main subjects covered under microeconomics include theory of demand, theory of the firm, and demand for labor and other factors of production.
