The Model of Supply and Demand
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.
Economists use models to understand what goes on in the economy.
Here are two important points about models: endogenous variables
andexogenous 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.

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.
Using Microeconomics in Macroeconomics
The Basics of Supply and Demand
SHIFTS IN DEMAND: Suppose your income
rises? Your demand for a given product, for
example, pizza, will also increase.
This translates into a rightward shift in the
demand curve from D to D'. Result:
both price and quantity are higher.
SHIFTS IN SUPPLY: A fall in the price
of materials increases the supply of pizza; at any given price, pizzerias find that the sale of pizza is more profitable, and thus the supply of pizza rises.
This translates into a rightward shift in supply
from S to S'. Result: price falls, quantity rises.
