Economics: Supply, Demand, and Market Equilibrium

Status: public · Confidence: medium (0.82) · Basis: verified_sources

## TL;DR

Supply and demand provide a basic model for explaining how competitive markets move toward equilibrium prices and quantities.

## Core Explanation

Demand describes the quantities buyers are willing and able to purchase at different prices. Supply describes the quantities sellers are willing and able to offer. In the standard diagram, their intersection gives the market equilibrium.

## Detailed Analysis

Shifts in demand or supply change the equilibrium. Introductory microeconomics then extends the same toolkit to consumer choice, production decisions, monopoly, oligopoly, public goods, externalities, and welfare analysis.
