Adam Davidson, writing in the New York Times, says that the rise of college prices is a sign of market competition in elite colleges. If colleges publish a high price, they can attract top students with financial aid. The greater the reduction in the tuition, the more likely schools may be in attracting successful students to build the school's reputation.____________________________Adam Davidson在纽约时报上表示,大学学费的上涨是各顶尖大学之间竞争的标志.如果大学收取高额学费,他们可以吸引那些获得学费帮助的好学生.越减少学费,就越可以吸引成功的学生来给学校打广告.__________________________
