A set is a well-defined collection of distinct objects that share a common characteristic and are related to each other in some way.

In economics, sets are used to represent a wide variety of concepts, including consumers, goods and services, and possible outcomes.

The intersection of two sets is the set of all elements that are common to both sets.

The union of two sets is the set of all elements that are in either set.

The complement of a set is the set of all elements that are not in the set.

Set operations are used in economics to analyze a wide variety of concepts, including consumer behavior, market structure, and economic growth.

Set theory can be used to model the behavior of consumers in a market by representing consumers as sets of preferences.

Set theory can be used to analyze the structure of a market by representing the market as a set of buyers and sellers.

Set theory can be used to study economic growth by representing the economy as a set of resources and technologies.
