I believe the following explains the effects of the elasticity of the pure monopolist.....You will see from the visual,below, that the elasticity is purely random and is,figuratively, based on the roll of a die.

Monopolistic companies are cost setters unlike companies in suitable opposition that are cost takers. In suitable opposition, purchasers can extremely swap companies if the cost is purely too severe. the cost elasticity of call for is subsequently bigger consequently. below a monopoly, the organization can tinker with expenses slightly greater and human beings will might desire to pay.
