Suppose a university decides to alter its tuition schedule by separating its students based on how many years of college they have completed. most university programs require four years to complete. first-year students would get a 13% tuition reduction. second-year students would pay the normal tuition. third- and fourth-year students face an increase in tuition of 25 and 41%, respectively. fully explain whether this pricing strategy is based on a sound understanding of price elasticity of demand, or not.
