Comparative Statics. Given the tendency of markets to converge to competitive
predictions in an unfettered and competitive market, we can use this model to predict the
effects of changes in the world.
Changes in demand vs. changes in qty demanded. When one of the non-price
determinants of demand changes, it is necessary to draw a new demand schedule. This is

a. Intuition: One way to consider the problem of sensitivity is to ask the
following question: What happens to total revenue (TR) when price is changed?
