Economics Economics examines how people produce goods and services, how they distribute them among themselves, and how they use them. Economists deal with problems in such areas as management and labor relations, the setting of wages and prices, and the use of natural resources. They use computers and statistical analysis to construct mathematical models that enable them to determine how various economic systems work and to predict the effect of changes in the systems.
