Microeconomics is the study of how households and firms
make decisions and how these decision makers interact in the
broader marketplace. In microeconomics, an individual chooses to
maximize his or her utility subject to his or her budget constraint.
Macroeconomic events arise from the interaction of many
individuals trying to maximize their own welfare. Because
aggregate variables are the sum of the variables describing
individuals’ decisions, the study of macroeconomics
is based on microeconomic foundations.
What is Macroeconomics?
Microeconomics v/s macroeconomics
Macroeconomics is concerned with
aggregates and average of the entire
economy, such as national
income, aggregate output, total
employment, total consumption, savings
and investments, aggregate

Economists use models to understand what goes on in the economy.
Here are two important points about models: endogenous variables
and exogenous variables. Endogenous variables are those which the
model tries to explain. Exogenous variables are those variables that a
model takes as given. In short, endogenous are variables within a
model, and exogenous are the variables outside the model.
This is the most famous economic
model. It describes the ubiquitous
relationship between buyers and
sellers in the market. The point of
intersection is called an equilibrium.
