1. Price elasticity of demand (hereafter ped) describes the responsiveness for prices changes of a particular good/service. It is measure from 0 to minus infinity. A ped between -1 to 0 is known as inelastic and this means that less responsive to price changes (0 is the extreme end, known as perfect inelastic and it means that consumers will not change the amount they purchase no matter how high the price changes to). A ped between -1 to minus infinite is called elastic and it means that consumers are very responsive to price changes (minus infinity is the other extreme end, called perfect elastic and it means that consumers will not buy anything even if the price just goes up by 1 cent).

Numerically, say the ped of some good is -2, this means that when price goes up by, say, 10%, then the quantity sold would decrease by 20%. If the ped of this good is -0.5, this means when price goes up by 10%, then quantity sold would only decrease by 5%.

PED is important for sellers to decide whether or not they can increase their prices ...
