Now it is possible to pass to analytical calculations. We have to are interested two moments: first, what 2 value, that is a tilt angle of new, less elastic function of demand and what expenses have to be has to be that to turn the P1(Q) function into the P2(Q) function. Let's remember that
It is natural to assume that all these expensive actions for formation of the market will be made by behavior of consumers less reacting to the change in price. It, of course, will lead to that the curve of demand will become more flat, and function of demand of less elastic.
