---

Equilibrium is the situation when demand and supply come together and fix the price in the market. The market is cleared because consumers demand what producers have to sell.

The equilibrium will change when the demand and supply curves move.

A contraction occurs when the demand/supply decreases. An extension occurs when the demand/supply increases.
