Why is Demand Important?

Fortunately, the concept of demand iseasy to understand because it involves onlytwo variables - the price and quantity of aspecific product at a given point in time.

So, when it comes to demand, there are twotypes of changes that can occur. When the price of a productchanges while all other factors remainthe same, we have a change in the quantitydemanded. Sometimes other factors changewhile the price remains the same -when this happens, we see a changein demand.

Only a change in price can cause achange in quantity demanded.When the price goes down, the quantity demanded increases. Whenthe price goes up, the quantity demanded decreases. Both changesappear as a movement along the demand curve.
