A 1998 study indicated that the price elasticity of demand for four-year university was .67. Using this estimate, how would a 10% increase in tuition at a four-year university change expected enrollments? Do you think the price elasticity of demand would be higher for an individual school (e.g., UNM, Harvard) or at the aggregate level (e.g., all 4-year schools). Why? What other factors do you think affect tuition elasticity?
